First check of one key opens the door and not the other. this is happens when cars are recovered after theft and new ignition key and switch are reprogrammed. If bother keys work, then a possible bad chip in your key (locksmith could fix this). Please click on "Mark helpful" if you're happy with the respond. Good luck :-)
Bad chip on the key. Key will open doors even with bad chip, doors don't have a chip sensor like the ignition
That's correct, doors don't have RFID sensors but the objective is to compare the key teeth cut. This will help indicate if its original or made after market.
Apparently Chip was fried, cost 250 for new key!!
