I bought a keychain remote off ebay and I cant seem to get it programmed. What is the procedure for a 98 mark? Thanks.

dont quote me on this but it dont hurt to try on my 97 t bird you had to turn the ignition on and off 8 times real fast and the dors would lock yhen open press the new remote and it will be programed like i said dont quote me on it but doesnt hurt to try

I don't know if the procedure for a 98 is the same as a 97, but try this and see if this works;

* Obatain all remote transmitters

* Enter the 5 digit permanent code into the keyless entry pad located on
the drivers door.

* Within 5 seconds:
*Press the 1-2 button on the keyless entry pad.

* Within 7.5 seconds:
*Press any button on the first remote transmitter.
(Doors should lock and then unlock)

* Within 7.5 seconds:
*Press any button on the second remote transmitter.
(Doors should lock and then unlock)

I hope this helps...
:)

Super Coupe is correct on the procedure. I had to do it earlier this year and I showed a used car dealer how to do it. Good stuff right there.
