Keyless Entry Key-Pad: Description and Operation
Keyless Entry KeypadThe keyless entry keypad, located on the exterior of the driver door, allows vehicle access without a key or remote transmitter. The keyless entry keypad feature:
- locks all doors, arms the perimeter anti-theft and inhibits the door lock control switch UNLOCK capability after 20 seconds (if the inhibit feature is enabled).
- unlocks only the driver door.
- unlocks all doors.
- releases the liftgate glass.
- enables/disables auto-locking.
The keypad feature functions independently of key position, vehicle speed, or transmission position. When a keypad button is pressed, the buttons illuminate to provide better visibility. If the 7/8 and 9/0 buttons are pressed or five seconds have elapsed since the last button press, the illumination is turned off.
Each vehicle equipped with a keyless entry keypad is programmed with a five-digit entry code. This code is provided to the customer through a wallet card in the Owner Literature package. In addition, this code is available through a diagnostic tool and is also printed on the vehicle security module label. When entering codes, each digit must be entered within five seconds of the previous entry.
Programming/Erasing Personal Codes
A unique personal five-digit code can be programmed by following these steps:
1. Enter the factory set five-digit code (the keypad illuminates when pressed).
2. Press and release 1/2 within five seconds of Step 1 to activate the programming mode.
3. Enter the unique five-digit code.
The personal code does not over-write the permanent factory set code. Either code can be used to access the vehicle. If a second personal code is programmed, it will simply overwrite the previous personal code. To erase a personal code, carry out the following procedure:
4. Enter factory set five-digit code.
5. Press and release 1/2 within five seconds of Step 1.
6. Press and hold 1/2 for two seconds.
The system now responds only to the factory set code.
Anti-Scan Feature
To provide added security, the keypad is disabled for one minute after 35 button presses without a valid entry code being entered. The keyless entry keypad flashes during this one-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-Scan turns off after one minute of inactivity of the keyless entry keypad.
Unlocking the Doors with the Keyless Entry Keypad System
To unlock the driver door, enter either the factory set code or the personal code (each digit must be pressed within five seconds of the prior digit). The interior lamps will illuminate.
To unlock all doors, enter either the factory set code or the personal code (driver door unlocks) and press the 3/4 control within five seconds.
Locking the Doors with the Keyless Entry Keypad System
It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, press the 7/8 and 9/0 controls at the same time with the driver door closed.
