Hi. My 1999 mondeo estate only has one key and it looks different to the keys in the manual. Mine has only two buttons on it , one with a triangle and the other with two. I've took it to pieces to fit a new battery but it had 3 in it, and the manual said it has one cr3032??. Also over the little bulb is a red piece of plastic and a 4 digit code number and sticker. Can Anyone help at all with this ?. Dont know whick batteries to fit etc.

hi there this might be of some use to you chap as theres diff setup look at bottom of this to see list of keys on link.

the 4 didgit is the code for the key regards pete

Obtain all keys fitted with remote control.

Turn ignition switch from position 0 to position II 4 times within 6 seconds.

Turn ignition switch to position 0.

The system will emit an acoustic signal to indicate start of programming mode.

Programming mode activated for 10 seconds proceed as follows:

Press and hold lock, unlock or boot release button.

Wait for acoustic signal (indicates correct programming).

Repeat above procedure within 10 seconds to program remaining keys.

To exit programming mode:

Turn ignition switch to position III or wait 10 seconds.

Hi Peter,

do you know if this process works only for new keys or will it work for reprogramming a second hand key

Thanks in advance

Chris

The posted procedure will set the key up to operate central locking but WILL NOT programme the transponder on a second key for the immobiliser.
