The information on both the Explorer and Expy keyless code is dead on, just traded to the Expy and am so glad I did. I enjoyed the Explorer, but I am disabled and have Spinal Cord Stimulator, and while I am not as flexible as I was, I still easily located the code behind the E brake along the firewall and programmed my two new FOBS. I wasn't aware of the PATS key and had two normal keys made but they obviously don't work.... Any Change anyone knows why this is a requirement? I suppose it's something like if you lend or someone had access to one key, they cannot dup without having enough access to grab two sets.... but I would think, it should have equally have been abled to be done with just some simple logic like a original and proof of ownership and ID... go figure... I guess I am just using the other side of my brain... (grins) Great Site, I am new on here, but have been involved in setting up many websites with forums and Chats, I am still pleased to find this one (and not having to maintain it, makes me think it must be my B-day or something... LOL KUDOS!
