Key fob mystery?

[gazandlucy]

When i start my car with the spare key it doesnt want to ignite the engine , justs turns it over? I have changed the battery with no effect? The large square fob works fine.

Do i need to reprogram the fob? If so how?

Thanks

Hi
I think that your second key needs synchronising with the ignition. I believe this is a dealer job. Try doing a search for key synchronisation .

If its the remote key fob and you have replaced the battery im willing to bet you have lost the transponder chip out of the key, little black square thing that sits inside the key blade, when you take the fob off to replace the battery they fall out, if so it wont start as the vehicle doesnt recognise the pats system and the red light on the dash will flash repeatedly. If you cant find the transponder you'll need a new one plus coding to the pats system.

You don’t have to reprogram the fob. All you have to do is to call a auto experts so that you can also whether the cause of the problem.
