    Did you ever get this fixed? I have a similar problem with mine slowly it would stop unlocking the doors and then locking the doors started to go. This would happen with both remotes in the exact same manner so it is NOT the remotes. now they both work fine to pop the trunk and set off alarm but will not unlock or lock the doors

Hello, It seems as is if you have a remote that will not lock the doors all the time. There can be a couple of reasons that it wont work at times.1 it may have a weak battery,2 there may be some kind of residue inside the key fob itself such as tea,coke,water, or even sweat. This will short the fob out at times.Thank you

Drive side power door lock is not working


If the door lock works ok with a key, I would say the lock actuator is failing. Its a small electric solenoid that moves the lock rod.

I can't disable my anti theft device on my chevy malibu 2004 and my car will not start


This usually works.Lock the doors with the remote.Press lock twice sounding the alarm.Then press the unlock button twice.Your car should start now.If that doesnt work try this,Lock the car again with the remote once.Go over to the passenger side door and use the key to unlock the door then press in the door unlock all doors.Hopefully by now it worked.Now if none of these work your security probably malfunctioned and theres only two things that will work,One is disconnecting the battery for 5 mins then reconnecting.unlock doors.the start.If that doesnt work you'll have to take it to the dealer to get the security reset or replaced.The steps I have wrot you are the diagnostics to reset it.I hope these work for you and good luck.See ya had have a great day..

The auto door lock feature dose not work.


There is 3 relays in one of the fuse panels that are labeled doorlocks one of them is probably bad. Push the door lock button and find the one that is clicking this is the one that is back. This should fix your problem

The remte control key is not responding with the car


Hi abdumi0f,

Firstly, open your glove box and make sure Valet Mode is not enabled, if it is not, follow these steps.

Step 1: Open drivers door and leave open.
Step 2: Lock and unlock the driver’s door using the power door lock switch on the door.
Step 3: Insert key into the ignition.
Step 4: Turn key to on position and return to off position. (IMPORTANT - use ON position NOT ACC position). Do this 3 times within 10 seconds. Leave key in the ignition.
Step 5: Open and close the driver’s door 3 times. (Door should be left open after this step).
Step 6: ECU should respond by locking and unlocking the doors.
Step 7: Press any button on remote #1 twice. ECU responds by locking and unlocking the car doors.
Step 8: Press any button on remote #2 (etc.) twice. Each time the ECU will respond by locking & unlocking the doors.
Step 9: Remove the key from the ignition and the ECU will respond a final time with a series of door locks and unlocks. You're done!

Hope this helps,

No security system beep when vehicle is locked


check to see if your "interior cabin lights" fuse isnt blown it is a 15amp fuse one of the top two rows in your fuse box. i have a 2002 A4 avant and when that fuse blows my security beep doesnt make any sound but the doors lock.

Automatic door locks will not work


Probably the door actuator - a part inside the door that activates the lock, particularly if neither the interior lock switch or the remote do not lock the door.  Once the doors lock the horn will beep again - the lack of beep indicates the vehicle is not secure.

Security will not reset


The disarm switch on the latch inside the door is most likely defective, pull the door panel and test it for proper function.
