Has anyone had a problem with thier key fob's? On average twice a month mine will not unlock the vehicle and disarm the alarm. No matter what I do, and push all the buttons at random including the panic, close or far, I have to use the key and open the door, the alarm goes off and will only turn off when the ignition key is turned and started. Once it would not turn off even with the engine running, I was in the process of disconnecting the battery and it turned off, I now know that the alarm will turn off by itself after approx 3-5 minutes. The dealer has given me new keys as they said the RF was weak, last month both my wife an I had our keys and it happened again, nothing would open the vehicle and disarm the alarm. It seems to me the receiver is at fault, has this happened to anyone else?
