You cannot change the master code. You can add a personal code by following the directions in the owner's manual but you will need the Master Code to do so. It's usually on a sticker on one of the Trunk Life Rods. If it's not there, a dealer can retrieve it for you.
You cannot reprogram it. A dealer can get you the Master Code if you've lost it.
thats my question to you

Keyless entry will have a keypad built into the driver's door handle.
To reset the keyless entry system on a 1997 Mercury Grand Marquis, start by disconnecting the vehicle's battery for about 10 minutes. Then, reconnect the battery and enter the vehicle. Press the "1" and "2" keys on the keypad simultaneously, which should reset the system. After this, you can program new codes if desired.
