2003 Suburban key fob programming
Getting my burb back on the road after 2 years. Find only one fob working. Turn the key to run twice while holding door unlock down. The car enters programming mode. Press and hold lock and unlock on all 3 fobs. Each fob causes the car to go through the lock/unlock to show it's been recognised. Turn the key to run and back to exit mode. However only one fob (same one each time) works. Any ideas?
