Mercury 2000 Grand Marquis - Manual (Page 83)

See also Remote entry system in this chapter for more information.
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
• taped to the computer module
When pressing the controls on the keyless entry keypad, press the
middle of the controls to ensure a good activation.
Programming your own entry code
1. Enter the factory-set code (keypad will illuminate when pressed).
2. Press the 1/2 control within five
seconds of step 1.
3. Enter your personal 5 digit code.
Enter each digit within five seconds
of the previous one.
All of the vehicle doors will lock and unlock to confirm programming of
the new code.
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.
You can program up to three personal codes to unlock your vehicle.
These codes do not replace the permanent code that the dealership gave
you.
