How do you disable the automatic door locks on a Chevy Avalanche?

Answer 1

If the Avalanche is anything like a 2003 Chevy Silverado, you can program the door locks as follows: 1. With vehicle off, Pull back the High Beam headlight lever (High Beams are on) 2. Turn ignition key on and off twice (ON, OFF, ON, OFF) , then release the headlight lever. Your vehicle should respond my locking or unlocking the doors. 3. You can now PROGRAM your locks by pressing a three button code, using the unlock/lock buttons on your driver door. Your manual should have details of the buttons you should press. For example, Press Lock, Unlock, Unlock, - and your code will tell your when to unlock, or to unlock at all. Here are some of the possible Combinations (A and B) A - Do not Lock Doors Lock All doors When Vehicle Is Started Lock All doors When Vehicle is placed in DRIVE Lock All doors when Vehicle reaches speed of 5mph. + B Do not unlock doors Unlock Drivers side door only - when placed in park Unlock all doors - when placed in park Unlock Drivers side door only - when key is removed from ignition Unlock All doors- when key is removed from ignition. These are a few examples, that can be programmed by pressing the unlock/lock buttons (three times).. If you don't have your manual, then you can try random combinations. Once you enter your 3 button combination, the vehicle exits programming mode. You can now start the vehicle and test the locks. Or: Repeat the process.
