New Battery/ Dead Key

[x52006]

Hi All,

So I just changed the battery and when I got the X back the key isn't working. i can turn the key manually and lock and unlock the car, can also start it manually but the key functions don't work. It was working fine before the battery was replaced. Thoughts?

Thanks

I found it for you.Nothing complicated,I've done it twice already.
Here we go:
1. Charge the key for about 1 hour in the ignition.
2. Enter the vehicle and close the doors
3. Briefly turn the ignition on (key to position 2) and off (5 times within 5 seconds). Don\'t actually start the car.
4. Remove the key; press and hold the \'unlock\' button. While holding the \'unlock\' button, rapidly press the \'lock\' button 3 times within a period of 10 seconds.
5. Release the \'unlock\' button.
6. The central locking system activates and releases all locks in rapid succession to indicate that the initialization has been successful.
7. To initialize additional remote control keys (make sure that no more then 30 second elapse between each initialization procedure) repeat steps 4 and 5 ONLY. Do not repeat step 3.
8. NOTE: You MUST initialize all the keys (at least that is what I found, otherwise by initializing one you de-initialize the others).

My has stopped working to after a battery change, did your inside lights come on when you opened a door and did the main door lock button still work?

Hi Rome,

Did your battery work prior to the battery change? yes my inside dome lights did work and so did the main door lock. Sounds like you just need to reprogram your key. Worked for me.
