Which battery? The car or the key battery?

I replaced the car battery! Thanks!

Ok, sorry, my bad, your Key battery uses a rechargeable battery... Does one of the keys look like the one in this link on the right?..

Just initialized, repeated about 10 times nothing happened?! It is still dead! My key is diamond shape, is it possible, even though the key supposed to be charged by ignition, that something is wrong with the key?! Many thanks!

Maybe I should mention that even though the lock was a bit stiff I managed to lock the door manually first evening. The next day I unlock, with difficulties, but lock cylinder is not responding now the key is just turning. I am wondering is it possible that something in the door mechanism is in a wrong position which interferes with the signal of the central locking. Yee, I checked the key, is sending the signal so that is ruled out.

Yes, a failed door lock actuator will have an effect to what you are experiencing, have that repaired first, you'll have to fix it anyway. I'm thinking once you have that fixed, all your other issues will go away. If not, then the battery in the fob is not holding a charge and it's time for a new one.


Hi Mark, thanks for the tip, I managed to initialized, and eventually everything is working, as far as key central locking is concern. My worry is now the door barrel, if I put a key in its turning freely without any resistance. Do you think is loose conection with locking mechanism in a door itself?! Many thanks!
