My 2000 Siverado 1500 power door locks are locked and wont open with a key or the lock button. How do I get my door open and what could possibly cause this?

You may need to reprogram the fob GM vehicles are equipped with keyless entry systems. GM cars and trucks are equipped with keyless entry capabilities. This technology gives owners the ability to remotely control their vehicle's door locks, trunks, engines and panic alarms. You can program or reprogram your keyless-entry FOB system in just minutes from your vehicle. Programming requires only your ignition key and your keyless remote itself and you will be ready to use the device immediately with your car, truck or SUV. Enter your GM vehicle with your keyless remote and your ignition key in hand. Close all of the car's doors behind you. Insert your key into the ignition and press and hold the "Unlock" tab on your driver's side door. Be prepared to hold the tab through the next step. Turn the key in the ignition to "On" and then back to "Off" two times in quick succession. Release the "Unlock" button on the driver's side door and wait for the car's locks to cycle to indicate the beginning of the programming sequence. Hold down the "Unlock" and "Lock" buttons on your keyless-entry remote until the doors respond by cycling again. This will indicate that the programming was successful. Repeat step five with any additional remotes and turn the key back to the "On" position to end the programming sequence once you have finished.

OR.. If and when you get inside..... close all of the doors behind you as your get in with your remote and ignition key. Insert your key into the ignition and hold the "Unlock" tab on the driver's side door. Cycle the key in the ignition "On" and then "Off" twice in a row and then release the "Unlock" tab on the door. Wait for the door locks to automatically cycle and hold down the Lock and Unlock tabs on your keyless remote. Hold the locks for up to 30 seconds until the door locks cycle again and turn the ignition switch to the "On" position when you are done to end the procedure.

I am not Mark .....don't feel bad it happens all the time, that is a place to click if you think my answer was helpful I must admit is looks like it is a name, answered by "Mark helpful"

This didn't work. Tried it several times. Anyone have any ideas. Still cant get the door open

I will ask some other guys. sorry 'bout that. I thought I was on to something

But how did you try it if you can't get the door open" You must be in the car to do it....?

sorry should of clarified. The only door that will not open with the key, remote, or the switch is the drivers door. Passenger door works fine. I have to climb over any time I drive.
