I'm trying to program a new fob, but my door locks don't cycle when I turn the key from off to run 4 times. I've tried several times doing it as fast as I can to meet the 3 second requirement. Any idea why my door locks won't cycle? Thanks.

You need to turn it 8 times for the locks to cycle and enter the programming mode. HTH. -Jim
