I just bought 2 new key fobs on ebay that come with easy-to-use programming instructions. I'll let you know how well they work. I also have re-keyed vehicle ignition keys. The original the owner left with her mechanic by mistake. I have two copies. They both work in the lock and the ignition. Sometimes it may not turn the first time so I may have to flip the key over of back it off a bit so the teeth hit the tumblers.
