Not to hijack the thread, but I also would appreciate some feedback about a Corolla key question. I bought my 2006 Corolla new. It now has 122,000 miles on it. It came with two regular keys, two fobs, and a valet key. I have always used one particular key and fob. I keep the other regular key and fob at home as spares but have rarely used them. I store the valet key at a relative's house, so that someone could bring me a car key in case I lost mine while I was out somewhere. Yesterday, the favorite key quit working. It would not turn in the ignition to start the car. It would unlock the doors, but it would not lock them. The fob worked fine. I had to get a tow home, and the first thing I did was to try my never-used spare key in the ignition. The spare key worked fine and started the car. I then held the two keys side by side and carefully compared them, and it did look as if the more used key is worn. Some of the little bumps and ridges are a bit rounded off. I have driven the car several times now with the spare key and have had no problems, so I think there is probably nothing wrong with the ignition or with the electronics of the car. I do want to get another key made to keep as a spare, but those chipped keys are expensive. I'm thinking that my old, worn key's RFID chip probably is still functional. I'm wondering if, instead of buying a new chipped key, I could just leave that old key inside the car permanently to give the car's ignition system the okay to start. Then maybe I could just get a cheaper, non-chipped key to actually stick in the ignition. Does anyone know if that will work?
