Question about 2003 Chevrolet TrailBlazer

1 Answer

I just purchased a 2003 trailblazer and the power lock buttons won't work correctly. one min. we think it is set and then it just locks and unlocks by its self ? we set it to lock when it is shifted in to gear, it works fine and then the next time we start the vehicle it won't do it ? I also can't get the interior lights to worck correctly they won't go off unless I use the manual override button! Could this be a wiring problem ?

You could have a short in the wiring harness flex point on the drivers door. Peel back outer layer and inspect for shorts. Good luck!

Power door lock switch?


Sounds like the drivers door lock switch is bad an as far as the auto start remote the contacts under the button get dirty and won't make contact, open the remote like changing the battery and you can probably get at the contact button, if it's a little carbon button they can be cleaned with a pencil eraser and then paper tower with a bit of rubbing alcohol, if it's an actual switch you can try spraying some contact cleaner into the switch. let it dry before you put the battery back in.

How program my keyless entry remote for my 2003 chevy trailblazer


1. Close all doors
2. Insert key into ignition
3. Hold down the power UNLOCK button on the driver's door panel, continue to hold down
until instructed to release in step 9.

4. Perform steps 5 through 8 in a fairly rapid succession.
5. Turn the ignition to the ON position (as far as you can go without starting the engine.)
6. Turn the ignition to the OFF position.
7. Turn the ignition to the ON position (as far as you can go without starting the engine.)
8. Turn the ignition to the OFF position.
9. Release the power UNLOCK button on the door panel. The vehicle should respond by
door locks locking and unlocking automatically. (If locks do not cycle after you let go,
not before you let go of the unlock button, then the vehicle has not entered programming
mode and you must start procedure over. Remove key from ignition, open drivers door
and return to step 1 ). If the locks do cycle automatically then proceed to step 10.

10. Hold down the LOCK and UNLOCK buttons on the remote until the doors lock and
unlock. This may take up to 30 seconds.

11. Repeat step 10 NOW for each additional remote. (Including any existing remotes).
12. Turn the ignition to the ON position to exit the programming mode.
13. Test remote(s).

2003 Monte Carlo SS, FOBS won't unlock doors (new batterries), use key and open the door with the door open FOB will lock and unlock the door, shut the door and the FOB won't lock the doors. After...


If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.

I locked my keys in my 2005 trailblazer how do i unlock the door?


you have to have a special tool that will reach over the top of your door window and then down to hit either the window control or door locks control...you can buy these at any auto parts store but any wrecker driver has these tools and can get in in less than 5 mins... a "slim jim" will not work unless it is manual door locks (as opposed to electric)

2003 audi a4 had dead battery, charged battery and now the key fob won't work and the security lights flash for about 5 min everytime I do anything to the car. why ?


Synchronization
When
Key buttons operated repeatedly while vehicle out of range and system becomes inoperative. Key batteries replaced.
How - early models
Depress lock or unlock button. Manually lock and unlock driver's door within 30 seconds. System should operate normally after approximately 1 minute. If not, carry out programming procedure.
How - late models
If vehicle locked, manually unlock driver's door using key. Press key unlock button once. Switch ignition ON and OFF. Remove key from ignition switch. Press key lock or unlock button once. System should now operate correctly.

03 trailblazer autolocking upon startup


The key in the ignition unlock feature works when the vehicle is turned off, not in the running position. You should have a feature built into the radio that lets you go in and set features like your locks, lights etc. Look in the manual under the Radio section. I think you have to hold the lower left large button in to activate menu, but it is a little different on certain models. Some have a set button.

Hope this helps
