Re: Spare Key - not working
I purchased a used 2008 mercury mariner hybrid early this fall and it came with 2 identical FOB keys. i do not recall verifying that both keys worked, but my wife and i have 2 sets if identical keys for both our cars and frequently exchanged them. We have small kids, both of us work and we are very busy, utility is most important.
Last month, my car would not start with my key, the one I had always been using. I never thought to try my wife's key, you just assume it is a car problem not a key problem. after alot of riggormarole and almost having my car towed, I accidentally tried my wife's key and the car started. then I figured out it was the key.
i took the car to the dealer. all buttons functioned properly, it seemed the security on the key did not work, or broke. After several attempts to reprogram the key, I was told that the key took the program, but still did not work in the car.
Essentially, all the mechanics, the service manager and the branch manager all looked at each other and shrugged their shoulders. Never saw it before and did not know what to do to fix it. Of course, I had to buy a new key and pay to have it programmed.
