I like the modification. I have keyless entry on my Expedition & 89 Town Car. Yes I got locked out of my HD F150. I was washing during the cold weather, kept the engine running while drying, went to go home & sure enough I got locked out. (left it running for about 20 minutes while I got my spare keys. I am glad I only lived 4 miles away)I had a friend shave down a key for my wallet, & it has been used a few times!!!!! I think I will try the keypad as well. thanks for the idea.
