A few years ago I was picking up take out pizza in during a winter snow storm and locked my truck with the motor running. When I came out to unlock the keypad, it did not work and stood there in the snow with a pizza in my hand. I tried the new code as well as the original factory code and got nothing. I got a ride to my house 2 miles down the road and came back with my spare keys. My truck went to the dealership the next day and I was covered under warranty. It was a defective keyboard actuator part # XL1Z*14A626*AA. Good luck with your repair.
