Key fob sync?
Hi to all!
Apologies if this may sound redundant, what is the right key fob sync procedure?
I have read and done the insert ign switch 2 clicks, press/unpress lock, press and hold unlock while press 5 times lock, wait 5 secs then press lock/unlock button or the insert key while it system recognizes key....
Until now i havent synced my 2 keys. It used to work 2 days ago and all of a sudden both dont work now in locking and unlocking the doors. The keys can start the car and the metal blade can open it manually, its just a hassle to open it through that. Batteries are new also.
Any help is very much appreciated.
Thanks

It might sound a bit crazy but have you checked the batteries in the key fob? Happened to me both batteries were dead at the same time albeit one key is very seldom used.
