How do you program a factory alarm remote on a 2002 Chevy trailer blazer?

Answer 1

1. Insert key 2. Hold down drivers side unlock button 3. Turn ignition to on position and back to off position three times (on,off,on,off,on,off) 4. release unlock button. (door locks will cycle) 5. hold down the lock and unlock buttons on the remote at the same time. (locks will cycle again) 6. Remove key, the remote should now work (unless is is not the right frequency for your car, in which case the locks wouldn't have cycled the second time)c
