Lost your key fob or need to program a new one for your 1997 Mercury Grand Marquis? Don’t worry, programming your key fob can be a straightforward process you can handle yourself. This guide will walk you through the steps to program your key fob, saving you time and potential dealership costs.
For 1997 Mercury Grand Marquis models, the key fob programming procedure utilizes the vehicle’s keyless entry keypad. Here’s how to program your key fob:
-
Enter Factory Code: Locate your 5-digit permanent entry code. This code is usually found on a sticker in your owner’s manual, glove compartment, or on the computer module itself. Enter this 5-digit code into the keyless entry keypad on your Mercury Grand Marquis.
-
Initiate Programming Mode: Within five seconds after pressing the last digit of your entry code, press the “1/2” button on the keypad. If successful, all doors will lock and then unlock. This lock cycle confirms that your vehicle has entered programming mode and is ready to learn new key fobs.
-
Program the First Key Fob: Within five seconds of initiating programming mode (pressing the “1/2” button), press any button on your first key fob transmitter. Upon successful programming of this transmitter, the door locks will cycle once again.
-
Program Additional Key Fobs (Optional): If you have additional key fobs to program (up to a maximum of 4), you must program them within five seconds of the previous successful programming. Press any button on the second transmitter. Repeat this step for any additional key fobs you need to program. It’s crucial to note that if the keypad light turns off before you have programmed all your transmitters, you will need to repeat the entire process from the beginning.
-
Exit Programming Mode: To finalize the programming and exit the mode, simultaneously press the “7/8” and “9/0” buttons on the keypad. The door locks will cycle one last time to indicate that the programming mode has been exited.
Now you should be able to use your newly programmed key fob to lock and unlock your 1997 Mercury Grand Marquis. If you encounter any issues or the key fobs do not seem to be working, double-check each step and ensure you are within the time limits specified. Programming your key fob yourself can be a convenient way to regain control of your vehicle’s remote entry system.
