Keyless Entry: Description and Operation

INTRODUCTION
The system allows locking and unlocking of vehicle door(s), deck lid release, and panic by remote control using a hand held radio frequency transmitter. The vehicle must be in PARK before the trunk lid can be unlatched with the transmitter.

The receiver may receive signals from up to four transmitters. Each transmitter has its own code, and the code is programmed and stored into receiver memory If a transmitter is replaced or additional transmitters are added, the codes for all units have to be reprogrammed into the receiver memory If a receiver module is replaced, the transmitter codes must be stored in the new receiver memory.

OPERATION
The transmiter 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 live 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 the PANIC button will cause the panic alarm to sound for three minutes, until the panic button is pressed 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.

Horn Chirp Toggle
Once the transmitters have been programmed, the horn chirp can be enabled/disabled by sending the horn chirp toggle operation code to the Body Control Module (BCM). This can be done using a DRB scan tool or by the customer. The horn chirp will enter the opposite state of its current programmed state by receiving this operation code. The BCM is responsible for keeping track of the horn chirp status.

SYSTEM OPERATION
Keyless Entry
The system allows locking and unlocking of vehicle door(s) and deck lid by remote control using a hand held radio frequency (RF) transmitter The ignition switch must be OFF before the trunk lid can be unlatched with the transmitter.

The receiver may receive signals from four transmitters (vehicles are shipped with two). Each transmitter has its own code and the code has been stored in memory, If the transmitter is replaced or other transmitters are added, the code for each unit must be learned.
