How can you Change the keyless entry code 1997 mercury mountaineer?

Answer 1

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.

If you wish to erase your personal code, use the following instructions:

1. Enter factory set code.

2. Press 1/2 control and release.

The system will now only respond

to the factory set 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.
