Thanks for your prompt reply. As you suggested , I used the second remote and all it does is lock and unlock the doors, or trunk; not the slightest motion from the top or even electronic noise. (I must say, I never used this key before for that purpose,first I should check the battery!!!!!!!
If it is the sensor, can I trust the dealer to give me an honest diagnoses. Is this an expensive part, or is it a DIY job?
Thanks
