My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Try disconnecting the battery with the key out of the ignition.Wait about 5 minutes then reconnect the battery and then leave it for about 5 minutes then try locking and unlocking the doors then see if it all works then o.k.If this does not work let me know.

If more help is needed, use the reply tab to continue our conversation.
