I had a problem with my door key and thought it was the key that was the problem. I then lost the remote so had a guy come from the dealer and he gave me a new remote and made a couple of keys and then those keys didn't work either and he said something was wrong with my lock. I asked if he could fix it and he said that they have about four motors in them. Has anyone had experience with this and how much does it typically cost to fix a door lock? someone probably tampered with it
