Have you replaced the battery lately? If so , you could have a bad battery in your key. It is a small microchip in some cares and will effect unlocking and starting the car if the battery is weak or dead.

Try doing a re-learn on the remote. If you don't know how, go to "you tube" enter the model of remote and you'll most likely get the information you need to complete the task.

I recently called the Volkswagen Dealership and spoke with the service manager about why my passenger doors no longer unlock using either of my two remotes...but all doors do unlock using the key in the exterior door lock, and by using the driver door master control switch. Note: The remotes are new, have been programmed by the dealership, and have fresh batteries in them. The VW service manager said "it sounds like the control module has a bad circuit". The fix would be a new control module, parts and 2 hours labor would be about $530.00. I mentioned that my original car battery is over eight years old and weak and needs to be replaced, and asked if that could be the problem. He said "NO that a weak battery wouldn't cause only that one single lock malfunction".

My husband went to the local auto parts store today and purchased a new battery for the car and installed it himself. Cost was just under $190.00 w/tax for the battery, but we purchased the top of the line "Interstate" battery. THIS FIXED THE PROBLEM! The remote problem is gone! All doors will lock and unlock as they did when the car was new! I'm happy to share the good news with everyone out there who may be experiencing the same problem. If your battery could be weak, try replacing it first before spending money on a new module. Cheers!

Check the batteries in your remote the may need replaced and if working OK check to see if you power locks work pushing the door switch. (If batteries are low they may not disengage both the alarm and the locks)

1. Start with key out of the ignition, drivers door is open all others closed and
drivers door is unlocked.
2. Insert key into ignition (Do not turn) and pull it out.
3. Perform these steps within 40 seconds.
A. Using the power door lock switch on drivers door perform 5 lock/unlock cycles starting
with lock. Use an even pace and try to go about one cycle per second.
(1 cycle = 1 lock and 1 unlock.)
B. Close, then open drivers door.
4. Perform these steps within 40 seconds.

Hi there,
Try adding a little WD40 to the lock itself. Use your hands to lock and unlock it to get the oil to spread. Put a little oil on the key, then put it into the lock. Use your hand and key to move it through the lock and unlock stages. I hope that this is some help to you. Good luck and let me know. Have a great night.~MWD

I recently replaced the battery on my 2004 Toyota Camry. When I installed new battery the door locks will not stay unlocked once opened with remote. How do I reprogram?

It was the part that attaches from the lock to the lock/unlock button. Thanks
