KEYLESS ENTRY SYSTEM
With the keyless entry keypad, you can:
• lock or unlock the vehicle doors
without using the key.
Your vehicle has a factory set 5 digit
code that operates the keyless entry
system. You can also program your
own 5 digit personal entry code. The factory-set code is located:
• on the owner's wallet card in the glove compartment
• or at your dealer.
When pressing the controls on the keyless entry keypad, press the
middle of the controls to ensure a good activation.
This system will disable the power door lock controls. These will not
work until the vehicle is disarmed.
Programming your own personal entry code
To program your own code:
5. Enter factory set code (keypad will illuminate when pressed).
6. Press 1/2 control within five seconds of step 1.
7. Enter your personal 5 digit code.
Enter each digit within five seconds
of previous one.
8. After the code is entered, the
locks will cycle, confirming that the
new code has been set.
Do not set a code that includes five of the same number or presents
them in sequential order. Thieves can easily figure out these types of
codes.
Your personal code does not replace the permanent code that the
dealership gave you. You can use either code to unlock your vehicle. If a
second personal code is entered, the module will erase the first personal
code in favor of the new code.

Anti-scan feature
The anti-scan feature prevents
repeated attempts at arriving at a valid key code.
The keyless entry pad is disabled for 1 minute after 7 unsuccessful
attempts (35 consecutive button presses) at entering a valid key code.
The keypad will flash during this 1 minute mode. However, the 7/8 and
9/0 controls will still lock the vehicle.
Anti-scan will be turned off after:
• one minute of keypad inactivity.
• the remote entry transmitter UNLOCK button is pressed.
• the ignition is turned to the ON position.
Unlocking the doors with the keyless entry 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 also illuminate.
To unlock all doors, enter the factory set code or personal code (driver
door unlocks) and press the 3/4 control within five seconds.
Locking the doors with the
keyless entry system
It is not necessary to enter the
factory or personal code prior to
locking all doors. To lock the doors:
• with the driver's door closed, press the 7/8 control and the 9/0 control
at the same time.
