can you reprogramme your key yourself as ive just getting a new 3 button fob and programmed that to open and close the doors but now my key wont start the car, ive got the spare key black with a red square on the edge but im not sure if thats the master key i need to get a dealer to do it, but id like to avoid that if i can as it wont be cheap.
thanks for any help

 

thats the master key m8 as for reprogramme new key dont go to main dealer try and find a small garage

 

if you find a small grage it should be about £40-60 not the £100+ from main dealer

 

here you go try this i take it it's a ford

i know it says radio code but it will do keys as well

 

That will programme the key to work the locks, but the transponder needs programmed for the immobiliser.

 

Take the transponder out of the old key fob and put it in the new one.

 

On pre 1998 Fords, the master key is a solid red key. Slave keys are black with a red chip.

One post 1998 Fords, the first 2 keys programmed into the system are the masters (you turn one in the ignition, remove and do the same with the 2nd to open the system for programming), regardless of remote key or not. Any key programmed after that is a slave key. You can have 4 remote keys and a maximum of 6 or 8 keys total on the later systems.

 

cheers for advice fellas, so if i get a new key cut to put with the new fob and put that key in after ive put the original keys it should reprogramme it, can only give it a try
