Can no longer remote lock/unlock vehicle, new batteries in key fob no help. I tried the single key and double key method to re-program the fob, no help. I heard it might help to unplug the control module, but I don't know where it is located. Thanks!

Re: central locking system stopped working
If the A6 layout for the modules is the same as my A4, the lock pump is in the rear corner of the car, on the passenger side. In the trunk, pull up the carpeting behind the passenger rear wheel, and tucked down in there is the pump assembly. They're known to go bad and it's a pretty likely cause for your problem, provided your fuses are not blown.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You are going to have to use the Key fob or remote alarm fob to go threw a set of lock and unlock procedure. Crank the car shut it off remove the key outside the vehicle at a distance of at least 30ft then lock the car, wait till it arms and the dash light blinks once this is active you want to unlock the car with the remote. If this one does not work do the same thing except when you unlock it do so with the key to re open after arming security.Also make sure you have both fobs or all remote fobs with you when you do this lock with one unlock with the other then vise, versa ok if you need any further help just ask also make sure your battery is fully charged and the terminals are clean this will affect a security system bad a low battery or low battery in the FOB's.
If the key turns in the lock, but does nothing, then the linkage has become disconnected or broken. The key is mechanical to the lock and the lock has a electrical switch to operate the central locking unit. Could be a simple broken clip from the lock barrel. Hope this helps
Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.
Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed
try putting the key in the ignition and turning it to on then holding the unlock button for 30 seconds and then remove the key and try the remote if still no good go to your dealer and get them to reinishalise the system
Have you you tried just re-programming all of your remotes? I just added a "new" (from Ebay) remote and when re-programming, had to do them all. Here's how...
1.Using a functional key fob transmitter, unlock the vehicle and disarm the Vehicle Theft Security System. 2.Insert ignition key into the ignition switch. 3.Turn the ignition switch to RUN position without starting engine. 4.Using a functional key fob transmitter, press and hold the UNLOCK button for a minimum four seconds (maximum ten seconds) 5.While holding UNLOCK button, and before ten seconds passes, press and release the PANIC button. A single chime will sound to verify that the RKE module is set to receive the new Vehicle Access Code(s) 6.Within 30 seconds of the chime, press and release the "LOCK" and "UNLOCK" buttons on the transmitter at the same time. Then press any one of the buttons. The BCM will sound an abbreviated chime to acknowledge that the programming of the transmitter has been completed and was successful. 7.Repeat step 6 for all transmitters that will be used with this vehicle (up to 4 total) 8.Programming mode will last for 30 seconds. To get out of programming mode sooner, turn the ignition OFF. A single chime will sound to verify that the RKE module will no longer accept additional Vehicle Access Code(s) 9.When Vehicle Access Code(s) programming is complete, turn the ignition switch to the OFF position and verify RKE system operation using each key fob
