Hello everyone.. I'm having some issues with my 03 Silverado's key-less entry.. Every time that I try to program the new fob, (holding the unlock while cycling the key 2 times the locks cycle and horn honks) 5 second into it the process the horn honks exiting the programing process... It's a brand new fob with new battery in it... Any ideas as to what my be the issue and how to resolve would be great... Thanks Jason

 

I've done a lot of research on this and everything I've found doesn't fit my problem... I've replaced both door lock buttons in the doors and tried another BCM still the same problem..
