I assume you did the re-synchronization process after putting in the new batteries ... Stand 5 feet away from the car and then ... Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds
I did see that that back in 2003 there was a technical service bulletin about this issue (03-08-52-001C). This had to do with the passenger door module (PDM) which is in the door and receives the fob signal.
Just to be sure also ... check that the passenger area fuse/relays are OK

SOURCE: Keyless remote Problem for Yukon Denali 2005

Have your dealership test the remotes for you, they will also use a "Tech-2" to re-program it and should not charge you to do so. "I know mine does not" The "puddle" lamps come on when you un-lock the doors with the remote."If they are enabled in the options on your dash information center or "DIC". "See owners manual for info on that". As far as the DRL's make sure your bulbs are good because they are known to blow out. But the remote should not have anything to do with those.Hope that helps a little?

SOURCE: how come on a 2002 GMC Denali if you lock your key inside

i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.

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).

Check the buttons.. I have an 06 Grand Prix with the Remote starter on the top and it seems that the conductor on the buttons worn out.. Take the keyfob apart, pull the rubber buttons off the chip, lick your finger and touch the place where the unlock (right side of the fob) would be. That should unlock your doors. I just did it with mine. I would just buy another fob on ebay and change the buttons out.. Hope this works

Key will not turn or open any doors


Got the right key? Is this a new buy for you? Does it work in ignition? If so then the ignition lock's been changed and you don't have the door key.
Or dead battery in fob, if you mean the remote function. (Frozen door lock barrels? Penetrating oil soak for an hour or 2)

Sorry that's all I can think of given the info provided.

Key fob is not switching off alarm or lockin the vehicle, Mitsubishi Shogan Sport 2003, I have changed battery in the fob


  • Check your remote to see whether it is held together by a small Philips-head screw. If so, remove it. Look at the join seam that runs along the middle of your remote. Search for a small indentation in which your miniature flathead screwdriver can be inserted. If not, use the seam itself, and gently pry it apart with your flathead screwdriver.
  • Spray the inside of the remote with canned air to remove any debris. Remove the battery, and dispose of it unless it is relatively new. It should be replaced when you re-assemble the fob.
  • Remove the button pad from the top of the remote, and using the alcohol with cotton swabs, clean around the buttons and the plastic frame it fits in to make sure it's clean. Lay it aside for it to dry.
  • Remove the remote's interior circuit board. Generally, the problem with remotes is that the contacts have worn thin and have ceased to make a proper electrical contact with the rest of the remote. These contacts are usually gold in color. Clean these with the cotton swabs and alcohol. Reassemble your fob, and check to see whether it works.
  • Reopen the fob if the clean contacts did not make a difference. To rebuild the contact surface, do one of several things: First, use a tiny bit of metallic paint applied gingerly with a paint brush or build up the contact surface by rubbing it with a pencil. Another solution is to use conductive coating, which is available at electronic shops. Let it dry 12 hours before re-assembling the fob and checking to see if it works.


  • Replace your battery, and close your key fob by pressing the two halves back together. It should click back into place. Replace any screws removed upon disassembly.

    My key fob is not working. Is there a way to reset the key fob? I have replaced the battery thinking that may be the problem.


    There are quite a few reasons a key fob might stop working, I just wish I could tell you what they are :)

    I can tell you there are some tricks to getting a key fob to work again.

    1) Change the battery
    I know you stated you tried this, but make sure you installed the battery correctly. Batteries don't last forever, you'll be surprised how often it's just a dead battery! Click here for a video on how to open a GM key fob, or search our YouTube channel on how to change a battery for your specific year, make, and model!

    2) Wipe the board
    The board inside your remote can get a lot more filthy than you think! When the board is dirty it can prohibit the contact to the circuit board when you push down on the button. Simply wiping the circuit board off can make your key fob like new again!

    3) The old car battery reset trick
    I know this sounds absurd, but it works sometimes and is worth trying. If you exhausted all of the options above, disconnect bot terminals on your car battery for 10 minutes. Then reconnect them and try your key fob. This has worked for many people and I have no idea why. If you do, please comment below to explain.

    4)New fob!
    It might be time for a new key fob! No need to dread over the expensive costs of a new key fob, at Keyless Entry Remote Fob Inc., you can get a refurbished one for a very affordable price! You won't even be able to tell the difference. Just search your vehicle make, model, and year to find your key fob or give us a call at 402-671-5100.
