Audi a3 central locking 2003

After reading your complaint for the thrid time it occur to me that there is a disconnection between the lock actuator and the lock itself. Remove the door panel and activate while observing. There is a couple of screws that need tightening

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

hi jamie,to reset the system,unlock the door/hold key over(windows will go down),then lock/hold key over(windows will go up/sunroof will close)then press unlock button on remote for 30 secs,RESET DONE.(if this dont work renew the battery in remote/reset again).geoff.

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.

what ever you do don't go to a audi shop as it will cost you a £1000.00 with out vat and £32.50 for every half hour of there time. try to resync. switch engine on with spare key and remove the remote fob from the key, shut the door and lock the door with the key within 5 seconds press unlock on the first remote to be coded untill the indicators flash once, wait 5 seconds and press unlock again to confirm this memory position. Remove ignition key and test remote if o.k repeat for other remotes adding extra positions by sitting indicators flash. position 2 will be two flashes. if no flashes then get the fault memory read. This may take a few attempts and lots of sweaing. Regards Samantha

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

More than likely your front driver door module has failed.  You will need to replace this module and readapt the key fobs for locking and unlocking

I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
