Keyless Entry Transmitter: Description and Operation

Fig.2 Remote Keyless Entry Transmitter:

The Remote Keyless Entry (RKE) system Radio Frequency (RF) transmitter is equipped with four buttons, labeled LOCK, UNLOCK, DECK LID RELEASE, and PANIC. It is also equipped with a key ring and is designed to serve as a key fob. The operating range of the transmitter radio signal is up to 10 meters (30 feet) from the RKE receiver.

Each RKE transmitter has a different vehicle access code, which must be programmed into the memory of the RKE receiver in the vehicle in order to operate the RKE system. Two transmitters are provided with the vehicle, but the RKE receiver can retain the access codes of up to four transmitters in its memory.

The RKE transmitter operates on two Panasonic CR2016 or equivalent. batteries. Typical battery life is from one to two years. The RKE transmitter cannot be repaired and, if faulty or damaged, it must be replaced.

The transmitter has four buttons for operation. They are LOCK, UNLOCK, DECK LID RELEASE, and PANIC.
- The UNLOCK button will unlock the driver's door and enable illuminated entry. Pushing and releasing the button once will unlock the driver's door. Pushing and releasing the button two times, within a five second interval, will unlock all doors.
- Upon pressing the LOCK button, the horn will sound a short CHIRP (if enabled) and flash the park lamps to notify that the all door lock signal was received and set. Illuminated entry is cancelled and the interior lamps are faded to OFF.
- Pushing and releasing the DECK LID RELEASE button (one or two times depending on customer preference) within a two second interval, will slightly ajar the deck lid.
- Pushing and holding the PANIC button will cause the panic alarm to sound for three minutes, until the panic button is pressed and held a second time, or the vehicle reaches a speed of 15 mph.
The receiver is capable of retaining a Vehicle Access Code (VAC) even when power is removed.
Each Remote Keyless Entry (RKE) module must have at least one and no more than four transmitters.

STANDARD PROCEDURE - TRANSMITTER PROGRAMMING
The Remote Keyless Entry transmitters can be programmed with the use of the DRB III- scan tool or by the customer.

DRB III Programming When using the DRB III scan tool, select:
1. "Theft Alarm"
2. "VTSS"
3. "Miscellaneous"and then the desired function.

Customer Programming
For a customer to be able to program RKE transmitters themselves, at least one RKE transmitter must be programmed already. This procedure is to add additional transmitters. If all transmitters are lost, the DRB III scan tool must be used to program the new transmitters.
