To disable the automatic door locks on a Chevy Silverado, unlock all the doors and with the engine turned off, pull back the turn signal and hold. While holding the turn signal lever, turn the ignition to the "on" or "run" position and then off. Repeat these steps twice, while holding the stalk. Afterwards, with the key in the "off" position, release the lever. The Silverado's doors should lock and unlock. The automatic feature can be reset from this point.
