How do you change the code for electric door locks on a ford thunderbird 1988?

Answer 1

This information can be found in your owner's manual. Don't have one, get one. Dealer or salvage yard is a source. This is quoted out of the Owners Guide for an '88 Turbo Coupe "In addition to unlocking by using the code appearing on your owner's code card or the warranty card, you may also program in a second code of your choice. To program this second code, you first have to enter the code from your code card. Then, within five seconds, press the 1/2 button. Then, within five seconds of each other, press five buttons in any sequence you desire. This button sequence is retained by the system as the second code. To erase this second code, simply enter the warranty card code, press the button 1/2, and wait six seconds." If you do not know the factory code (assuming the door is still factory): "A record of the permanent computer code for the keyless entry system can be found in four places: ~A sticker with the printed number code is taped to the exterior of the computer module located in the trunk. ~A second sticker with the code is taped on the lower left corner on the front of the Owner Warranty Card. This card is located inside the glove box. ~A third sticker is located on the inside of the trunk lid. ~A fourth sticker appears on a pocket-size code reminder card that will be found in the glove compartment." Hope that is a little more helpful than the last answer.
