Transponder
Transponder
The key has a built-in transponder with a unique identification code. When the key is inserted into the ignition switch and turned the ON position, the identification code is sent to the receiver located around the ignition switch. The receiver sends the signal to the TWICE control module, which in turn checks that the code is valid.
The transponder's identification is used for:
^ The electronic immobilizer
^ Central locking system
^ to unlock the car if it is locked when the key is turned to the ON position
^ to inactivate TSL and resume normal locked mode
^ Disarming the anti-theft alarm
^ Theft protection, audio system
Locking all doors
The central locking system can be operated with a key from the driver's door only.
To lock all the doors, the key is turned once clockwise (LHD) - or anti-clockwise (RHD). The boot lid cannot now be opened from the inside with the button on the driver's door.
When the key is turned in the lock a microswitch in the lock closes, grounding pin 7 (LHD), pin 2 (RHD), on the lock unit, whereby pin 56 on the TWICE control module is grounded.
A short voltage pulse (0.8 sec.) is output from pin 22 on the TWICE control module to the doors' electric motors, which locks the car.
The lock motors are grounded to the TWICE control module by
^ pins 26 and 42, driver's door
^ pins 69 and 66, passenger door
^ pins 49 and 20, rear doors
Unlocking all doors
To unlock all the doors, the key is turned once anti-clockwise (LHD) - or clockwise (RHD). The boot lid can now be opened via the button on the driver's door.
When the key is turned in the lock a microswitch in the lock closes, grounding pin 3 (LHD), pin 8 (RHD), on the lock unit, whereby pin 33 on the TWICE control module is grounded.
A short voltage pulse (0.8 sec.) is emitted from the TWICE control module
^ pin 26 to the driver's door
^ pin 69 to the passenger door
^ pin 49 to the rear doors
The lock motors are grounded to the TWICE control module by
^ pins 42 and 22, driver's door
^ pins 66 and 22, passenger door
^ pins 20 and 22, rear doors
Activating TSL with the key (Not US/CA)
To activate the TSL, the key is turned twice clockwise (LHD) - or anti-clockwise (RHD) within five seconds. The car horn sounds once to confirm TSL activation.
When the key is turned the first time, a microswitch in the lock closes, grounding pin 7 (LHD) or pin 2 (RHD) on the lock unit, whereby pin 56 on the TWICE control module is grounded.
A short voltage pulse (0.8 sec.) is output from pin 22 on the TWICE control module to the doors' electric motors, which locks the car.
The lock motors are grounded to the TWICE control module by
^ pins 26 and 42, driver's door
^ pins 69 and 66, passenger door
^ pins 49 and 20, rear doors
When the key is turned the second time within five seconds, the microswitch in the lock closes once more, grounding pin 7 (LHD) or pin 2 (RHD) on the lock unit, whereby pin 56 on the TWICE control module is grounded.
A short voltage pulse (0.8 sec.) is emitted from the TWICE control module
^ pin 42 to the driver's door
^ pin 66 10 the passenger door
^ pin 20 to the rear doors
^ pin 22 to all doors to ensure the lock motors reach their end positions.
The lock motors are grounded to the TWICE control module by
^ pin 26, driver's door
^ pin 69, passenger door
^ pin 49, driver's door
Inactivating TSL with the key (Not US/CA)
TSL cannot be inactivated with the key, but with the remote control by pressing the unlock button. Description and Operation However, it is possible to open the door in emergencies, see "Emergency opening" below.
Emergency opening
The drivers door can be opened mechanically with the key in emergencies, e.g. defect remote control or discharged battery. After the door has been emergency opened because of a defect remote control, all the doors will be unlocked when the ignition switch turned to ON and the correct immobilizer code has been identified. See Antitheft and Alarm Systems
If an anti-theft alarm is fitted, it will be activated by emergency opening but is disarmed when the ignition is turned to ON and the correct immobilizer code has been identified.
On the US/CA markets, the alarm is disarmed when the door is unlocked (emergency opening) with the key.
Separate unlocking of driver's door with key (US/CA)
The function can also be programmed for other markets.
To unlock the driver's door separately, the key is first turned once anti-clockwise (LHD) - or clockwise (RHD). The boot lid can now be opened via the button on the driver's door.
When the key is turned in the lock a microswitch in the lock closes, grounding pin 3 (LHD), pin 8 (RHD), on the lock unit, whereby pin 33 on the TWICE control module is grounded.
A short voltage pulse (0.8 Sec.) is output from pin 26 on the TWICE control module to the driver's door which is then unlocked. The lock motor is grounded to pins 42 and 22 on the TWICE control module.
When the key is turned a second time, the microswitch will again close, grounding pin 3 (LHD), pin 8 (RHD), on the lock unit, whereby pin 33 on the TWICE control module is grounded.
A short voltage pulse (0.8 sec.) is emitted from the TWICE control module
^ pin 69 to the passenger door
^ pin 49 to the rear doors
The lock motors are grounded to the TWICE control module by
^ pins 66 and 22, passenger door
^ pins 20 and 22, rear doors
