I ordered some "transponder" keys from Ebay. They were the ones with the remote in the head of the key. I took it to a locksmith I have used before that knows what he is doing for programming. The remote fob in the key head would work locking and unlocking the doors. The key would NOT start the vehicle and the Ford Security icon would flash on the dash.
The locksmith said that it was NOT a transponder key. My key to my 08 Escape has the letter "S" stamped into it. From research I understand this is a 40 bit key. My key is also a regular transponder key with separate key fob. The Ebay seller is adamit that is is a transponder key as their keys are all tested. Ebay seller says that it doesn't have a stamp because its an aftermarket key. I have seen other ebay sellers with aftermarket keys that HAVE a "SA" or "HA" stamp in the key (I understand this is a 80 bit key that is backwards compatible with 40 bit systems). I have NOT seen ANY keys with the remote head have any stamps on them. I spoke with a local Ford dealer who informed me that the IKT keys won't work UNLESS your vehicle came with it; as he tried with his F150 unsuccessful. I thought escapes came with IKT keys. Am I wrong? Was it an option?
Is it Possible that the IKT key I have is a transponder key but just wouldn't work on my Escape?
I've contacted the seller and am about to ship them back for a refund.
