I have a 2002 sport trac that key cylinder broke and getting it out it fell apart! We bought a new one with transponder keys and found out we would have to hire a locksmith to come program it! Long story short after trying everything, I bout a VEEPEAK MS(for MS-CAN & OBD 2). It connects to OBD port and laptop at the same time and costs abou $30 on Amazon. Also ordered correct transponder keys for my model(less than $2 each) you can find this on ford website. Returned key cylinder with transponder keys, got new key cylinder without transponders, took no transponder and new not cut transponder keys to be cut at Walmart, paid ford $10 for a year of use to be able to program or diagnose with OBD 2 , get into a program on computer to register and everything is explained step by step on how to do everything! It sounds like a lot but for less money than the original key cylinder with transponder keys, I have the ability and license to use the OBD2 programmer for a year on any ford! We tried bypassing PATS SYSTEM, but without original cylinder and keys it won’t work on a ford! You do have to make sure the keys ordered from Amazon are the right ones for your year and model ford also! It’s a good and bad thing about fords, it prevents theft, but dang if it isn’t aggravating figuring it all out! Hope this helps! By the way, I’m an old woman and if I can do it! LOL
