Anti-Theft - Passive Anti-Theft System (PATS)
Anti-Theft
NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).
The Passive Anti-Theft System (PATS) uses radio frequency identification technology to deter a drive-away theft. Passive means that it does not require any activity by the user.
The vehicle can be equipped with either conventional PATS (Passive Anti-Theft System) (standard equipment) or Intelligent Access (IA) with push button start (optional equipment). The conventional PATS (Passive Anti-Theft System) vehicle uses an Integrated Keyhead Transmitter (IKT) key and the IA (Intelligent Access) with push button start vehicle uses an IA (Intelligent Access) key. The IA (Intelligent Access) key uses radio frequency signals to be recognized by PATS (Passive Anti-Theft System) as a valid, programmed key before PATS (Passive Anti-Theft System) allows the vehicle to be started using the push button start.
Factory Invoiced Accessory (FIA) Remote Starter
Vehicles can be equipped with a factory-invoiced dealer-installed remote start system that is a Factory Invoiced Accessory (FIA). The remote start fob for this system uses a small device that is about half the size of a conventional Remote Keyless Entry (RKE) fob, but only has one button on it. If the remote start system is installed on the vehicle and the unlimited mode is not enabled, the PATS (Passive Anti-Theft System) allows up to 7 PATS (Passive Anti-Theft System) keys to be programmed into the Instrument Panel Cluster (IPC). The remote start system uses up one of the 8 total PATS (Passive Anti-Theft System) keys that can be programmed into the IPC (Instrument Panel Cluster). The number of keys that are programmed into PATS (Passive Anti-Theft System) can be determined by viewing the IPC (Instrument Panel Cluster) PID N_KEYCODE.
Passive Anti-Theft System (PATS) Function
Vehicles Equipped With Integrated Keyhead Transmitter (IKT) Key
NOTE: This vehicle uses a Strattec IKT (Integrated Keyhead Transmitter) key. If replacing an IKT (Integrated Keyhead Transmitter) key, it is recommended that the original Strattec IKT (Integrated Keyhead Transmitter) key be replaced with another Strattec IKT (Integrated Keyhead Transmitter) key. There are minor visual differences both externally and internally between the Strattec IKT (Integrated Keyhead Transmitter) key and IKT (Integrated Keyhead Transmitter) keys used on other Ford, Lincoln, and Mercury vehicles that may be noticed by the customer. These visual differences does not affect the IKT (Integrated Keyhead Transmitter) key functionality in any way. Rotunda should supply a Strattec IKT (Integrated Keyhead Transmitter) key when ordering replacement/new keys for this vehicle. Refer to the Owner's Literature for information concerning these differences. If replacing an IKT (Integrated Keyhead Transmitter) key (or adding another key) with a standard PATS (Passive Anti-Theft System) key (not an IKT (Integrated Keyhead Transmitter) key), any of the brands (Ford, Rotunda, Strattec or Huf) operates the PATS (Passive Anti-Theft System), but not the RKE (Remote Keyless Entry) system.
Vehicles with IKT (Integrated Keyhead Transmitter) keys were originally equipped with IKT (Integrated Keyhead Transmitter) keys manufactured by Strattec. Replacement IKT (Integrated Keyhead Transmitter) keys made by Huf work correctly, but can look and feel different. It is recommended that IKT (Integrated Keyhead Transmitter) keys be replaced with the same manufacturer's keys. Rotunda supplies matching keys by the same manufacturer if they are ordered by vehicle.
This vehicle is equipped with 2 IKT (Integrated Keyhead Transmitter) PATS (Passive Anti-Theft System) keys. The IKTs (Integrated Keyhead Transmitters) operate as a standard PATS (Passive Anti-Theft System) key with a RKE (Remote Keyless Entry) transmitter incorporated into the keyhead. The IKTs (Integrated Keyhead Transmitters) require batteries for the RKE (Remote Keyless Entry) transmitter to operate. The IKT (Integrated Keyhead Transmitter) battery is not necessary for PATS (Passive Anti-Theft System) operation. A maximum of 4 IKT (Integrated Keyhead Transmitter) keys can be programmed to operate the vehicle. If more than 4 IKT (Integrated Keyhead Transmitter) keys are programmed, the RKE (Remote Keyless Entry) portion of the additional keys do not operate and the SJB (Smart Junction Box) (the IPC (Instrument Panel Cluster) sets DTC B109E:42) sets DTC B1138 (Memory Full). These additional keys start the vehicle, but cannot operate the RKE (Remote Keyless Entry) system. If additional PATS (Passive Anti-Theft System) keys are desired, a standard PATS (Passive Anti-Theft System) key (a non-IKT (Integrated Keyhead Transmitter) key) can be used. For the purposes, the PATS (Passive Anti-Theft System) portion of the IKT (Integrated Keyhead Transmitter) key is referred to as a PATS (Passive Anti-Theft System) key.
The IKT (Integrated Keyhead Transmitter) key PATS (Passive Anti-Theft System) consists of the following components:
- Anti-theft indicator (located in the IPC (Instrument Panel Cluster) and depicts a vehicle with a padlock covering part of it)
- IKT (Integrated Keyhead Transmitter) key(s) (the key contains a PATS (Passive Anti-Theft System) transponder and an RKE (Remote Keyless Entry) transmitter)
- PATS (Passive Anti-Theft System) transceiver
- IPC (Instrument Panel Cluster)
- PCM
PATS (Passive Anti-Theft System) is active only for a few seconds when the vehicle is starting. It is not a PATS (Passive Anti-Theft System) concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS (Passive Anti-Theft System) cannot disable a running vehicle.
The PATS (Passive Anti-Theft System) function uses the IPC (Instrument Panel Cluster) and the PCM to enable or disable the engine. All elements of PATS (Passive Anti-Theft System) must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle cannot start. If there is a PATS (Passive Anti-Theft System) concern present, the IPC (Instrument Panel Cluster) sends a message to the PCM to not allow fuel injector or starter operation. If the vehicle starts and stalls, or the engine does not start at all, check the anti-theft indicator operation in the IPC (Instrument Panel Cluster) and if flashing or glowing, retrieve the DTCs from the IPC (Instrument Panel Cluster) and the PCM and follow the PATS (Passive Anti-Theft System) diagnostics.
PATS (Passive Anti-Theft System) disables the vehicle from starting if there is:
- a damaged IKT (Integrated Keyhead Transmitter) key.
- an unprogrammed IKT (Integrated Keyhead Transmitter) key.
- a non-encoded (non-PATS (Passive Anti-Theft System)) key (a conventional key or one that does not have any electronics).
- damaged wiring.
- a damaged transceiver.
- a damaged IPC (Instrument Panel Cluster).
- a damaged PCM.
PATS (Passive Anti-Theft System) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems can reduce the security of the vehicle, and also can cause no-start concerns. Remote start systems must be removed from the vehicle before any PATS (Passive Anti-Theft System) -related no-start concerns are investigated.
Unlimited Key Mode
PATS (Passive Anti-Theft System) contains a feature called unlimited key mode (available only on vehicles with IKT (Integrated Keyhead Transmitter) keys, vehicles with IA (Intelligent Access) keys do not have this feature). This feature allows a customer to program more than 8 vehicle keys, if requested. Each vehicle in unlimited key mode is set up with a special unlimited transponder security keycode. This allows all the customer vehicles to share the same mechanically cut keys. For an individual customer, any randomly selected security key that has been previously mechanically cut and electronically programmed to the vehicle is acceptable. Refer to Spare Key Programming - Unlimited Key Mode .
If unlimited key mode is enabled, a maximum of 4 IKT (Integrated Keyhead Transmitter) keys can be programmed to the vehicle for RKE (Remote Keyless Entry) functionality. If more keys are required, they should be standard PATS (Passive Anti-Theft System) keys. If more than 4 IKT (Integrated Keyhead Transmitter) keys are programmed to the vehicle, the SJB (Smart Junction Box) sets DTC B1138 (Memory Full) and the IPC (Instrument Panel Cluster) sets DTC B109E:42 (Remote Keyless Entry: General Memory Failure) and only 4 IKT (Integrated Keyhead Transmitter) keys have RKE (Remote Keyless Entry) functionality, however, all of them start the vehicle, if programmed correctly. Refer to Spare Key Programming - Unlimited Key Mode .
Vehicles Equipped With Intelligent Access (IA) Key
NOTE: The IA (Intelligent Access) key must be outside the vehicle for entry purposes, and inside the vehicle for starting purposes. The IA (Intelligent Access) key cannot operate the system if used in the opposite manner. In other words, the IA (Intelligent Access) key cannot be used for entry if it is inside of the vehicle and it cannot be used for starting if it is outside of the vehicle. This is done for security purposes. If an IA (Intelligent Access) key is inside the vehicle, and the operator is carrying another programmed IA (Intelligent Access) key, IA (Intelligent Access) entry is still allowed.
The vehicle is equipped with 2 IA (Intelligent Access) PATS (Passive Anti-Theft System) keys (Rotunda numbers are 164-R7030 for the mechanical key blade and 164-R7028 for the IA (Intelligent Access) key, less the mechanical key blade). The IA (Intelligent Access) key and mechanical key blade cannot be purchased together as a single unit. The IA (Intelligent Access) keys operate as an electronic PATS (Passive Anti-Theft System) key (there is no conventional key shank) and contain a transponder that allows the customer to access and start the vehicle without using a standard key. The IA (Intelligent Access) key must be located somewhere in the vehicle for vehicle starting. A maximum of 4 IA (Intelligent Access) keys can be programmed to operate the vehicle. If more than 4 IA (Intelligent Access) keys are attempted to be programmed, the additional IA (Intelligent Access) key(s) cannot function in any way.
The IA (Intelligent Access) key requires a battery to operate the RKE (Remote Keyless Entry) functions. If the IA (Intelligent Access) key battery fails or is low on charge, the IA (Intelligent Access) key cannot be used to start the vehicle unless it is placed in the backup transceiver slot.
NOTE: The list below does not include the door handle antenna and the rear fascia antenna as they are not used for starting the vehicle. for information on these components.
PATS (Passive Anti-Theft System) consists of the following components:
- Anti-theft indicator (located in the IPC (Instrument Panel Cluster) and depicts a vehicle with a padlock covering part of it)
- IA (Intelligent Access) key
- Front console passive start antenna (located in the front of the floor console)
- Rear console passive start antenna (located in the rear/bottom of the floor console)
- Rear seat passive start antenna (located under the middle of the rear seat cushion, attached to the floor pan)
- Backup transceiver (located in the left rear corner of the floor console, bolted to the console behind the left side panel)
- Remote Functions Receiver (RFR) module (located above the headliner, near the driver side sun visor area)
- Remote Function Actuator (RFA) module (located behind the glove compartment)
- PCM (located in the engine compartment, under the RH cowl)
The PATS (Passive Anti-Theft System) function is controlled by the RFA (Remote Function Actuator) module. PATS (Passive Anti-Theft System) uses the RFA (Remote Function Actuator) module to carry out all of the PATS (Passive Anti-Theft System) functions such as receiving the identification code from the IA (Intelligent Access) key, sending a signal to the PCM to control the starter and fuel injectors enable, and initiating the key interrogation sequence when the ignition state is changed to ON or START.
PATS (Passive Anti-Theft System) is active only for a few seconds when the vehicle is starting. It is not a PATS (Passive Anti-Theft System) concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS (Passive Anti-Theft System) cannot disable a running vehicle.
The PATS (Passive Anti-Theft System) function uses the RFA (Remote Function Actuator) module and the PCM to enable or disable the engine. All elements of PATS (Passive Anti-Theft System) must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle cannot start.
PATS (Passive Anti-Theft System) disables the vehicle from starting if there is:
- a damaged IA (Intelligent Access) key.
- a damaged IA (Intelligent Access) passive start antenna (of the 3 used for starting the vehicle).
- an unprogrammed IA (Intelligent Access) key.
- a non-encoded (non-IA (Intelligent Access)) key (a conventional PATS (Passive Anti-Theft System) key or one that does not have any electronics).
- damaged wiring.
- a damaged backup transceiver (only if the IA (Intelligent Access) key is in the backup transceiver slot).
- a dead battery in the IA (Intelligent Access) key (backup transceiver slot may be used to start the vehicle in this case).
- a damaged RFR (Remote Functions Receiver) module.
- a damaged RFA (Remote Function Actuator) module.
- a damaged PCM.
PATS (Passive Anti-Theft System) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems can reduce the security of the vehicle, and can cause no-start concerns. Remote start systems must be removed from the vehicle before any PATS (Passive Anti-Theft System) -related no-start concerns are investigated.
Backup Transceiver
The backup transceiver is located in the left rear of the floor console and its associated backup transceiver slot is located in the left rear corner of the floor console storage compartment. This slot allows the IA (Intelligent Access) key to be placed in close proximity to the backup transceiver for starting purposes. If the vehicle does not start normally, place the IA (Intelligent Access) key in the backup transceiver slot and attempt to start the vehicle. If the vehicle does not start normally at this time, refer to Anti-Theft - With Intelligent Access (IA) Inspection and Verification and follow the appropriate diagnostic direction. Make sure the transmitter buttons are facing forward and the key ring is up for the most efficient backup transceiver operation.
It is not recommended to leave the IA (Intelligent Access) key in the backup transceiver slot, as this decreases the security of the system.
Intelligent Access (IA) with Push Button Start Ignition Modes
The IA (Intelligent Access) feature does not require a conventional key to enter or start the vehicle. Once inside the vehicle, the operator activates one of the ignition modes using the brake pedal and the push button start (START/STOP) switch.
Intelligent Access (IA) with Push Button Start Ignition Modes
MyKey(TM) Feature
NOTE: The MyKey(TM) feature is applicable to both key types, the IKT (Integrated Keyhead Transmitter) key and the IA (Intelligent Access) key.
The MyKey(TM) feature allows a restricted driving mode to be programmed into one (or more) key(s) supplied with the vehicle or into any (PATS (Passive Anti-Theft System)) programmed spare key(s) to promote good driving habits. The MyKey(TM) is a restricted key for all consecutive key cycles until the MyKey(TM) restricted key is cleared. The remaining key(s) is referred to as an "administrator key" or admin key. There must always be at least one admin key. The IPC (Instrument Panel Cluster) does not allow the last admin key to be programmed into a MyKey(TM) restricted key. Both the admin key and the MyKey(TM) can be used to see how many admin keys and MyKey(TM) restricted keys are programmed to the vehicle, and how many total miles have been driven with the MyKey(TM) restricted key active.
When the MyKey(TM) feature is programmed, several features are modified including:
Standard Restricted Features
- NOTE: The standard restricted features below cannot be configured in any way.
Belt-Minder(R) chimes periodically with the audio system muted until the driver safety belt is buckled. If Belt-Minder(R) has been disabled when the admin key is in the ignition lock cylinder, Belt-Minder(R) still functions for the MyKey(TM) driver. Belt-Minder(R) cannot be disabled by the MyKey(TM) driver.
- Audible and visual low fuel warnings are issued when the programmed Distance To Empty (DTE) value is reached (typically 75 miles).
- The parking aid system (if equipped), Blind Spot Information System (BLIS(R)) with cross traffic alert (if equipped), and forward collision warning (if equipped) cannot be turned off.
Optional Restricted Features
- NOTE: The optional restricted features below can be configured to the customer preferences.
The volume of the audio system can be programmed to limit the volume to 45% of the maximum volume.
- Vehicle speed can be programmed to be limited to 130 km/h (80 mph). Audible and visual warnings are issued when the vehicle speed of 130 km/h (80 mph) is attained.
- Audible and visual warnings are issued when the preselected vehicle speed of 75, 90 or 105 km/h (45, 55 or 65 mph) is attained.
- The AdvanceTrac(R) always on feature can be configured on or off. If configured to always on, at this time the traction control cannot be disabled by the MyKey(TM) driver.
Refer to Information and Message Center in the Description and Operation portion of Instrument Panel, Gauges and Warning Indicators for all of the MyKey(TM) system checks and system warning displays.
Refer to MyKey(R) Programming or to the Owner's Literature for MyKey(TM) programming information.
Check MyKey(TM) System Status
The vehicle system check provides the status of the following MyKey(TM) parameters:
- MYKEY DISTANCE- This odometer only tracks mileage when a MyKey(TM) is used. If mileage does not accumulate, the intended MyKey(TM) is not being used. The only way to reset this odometer to zero is by clearing the MyKey(TM). If this odometer is lower than the last time it was checked, the MyKey(TM) system has been cleared.
- MYKEY(S) PROGRAMMED- Indicates how many MyKeys(TM) are programmed to the vehicle. It can also be used to determine if a MyKey(TM) has been cleared.
- ADMIN KEYS PROGRAMMED- Indicates how many admin keys are programmed to the vehicle. It can also be used to determine if an additional spare key has been programmed to the vehicle.
Refer to the Owner's Literature for information on accessing the MyKey system status in the message center.
Using MyKey(TM) with Aftermarket Remote Start System
When using an aftermarket remote start system, the default settings recognize the remote start system as an additional admin key. If the remote start system has not been programmed as a MyKey(TM) and the driver is a MyKey(TM) driver, the driver could drive the vehicle using the remote start system as an admin key with no MyKey(TM) restrictions. If requested by the customer to resolve this concern, the aftermarket remote start system needs to be programmed as a MyKey(TM). For information on programming the aftermarket remote start system as a MyKey(TM), refer to MyKey(R) Programming .
