I have a 2001 Ford F-150 XLT Supercrew that I installed a ford factory remote start/keyless entry into last year. Everything is working fine on it, but i'm trying to get into programming mode but it just won't do it. I do the instructions like it says in the installation/programming instructions but it won't chirp like it says it's supposed to.

I thought maybe the programming button was bad but it still works after I tested it and it still will enable the system if using keys to get into truck.

Please Help!
