Try a new battery in the KEY

yes it would you need to remove the battery and leave it of for a few hours. but with deadlock on its going to be hard to get in to open the bonnet. you need to jack up the front of the vehicle and remove shield to access the battery wires. and hook up another battery to the leads just so you can get the deadlock off, you will also need a new alternator as this is what has gone wrong. charging with the battery still connected can damage the regulator on the alternator and instead of not using power when the engine is off it will drain the battery. you can replace the regulator but its more than likely damaged the rectifier as well. trickle charge systems can be safe to charge batteries but they are no 100% any weakness in the alternator or ecu and this can happen.

Hi , this sounds like the fuse has blown for the central locking due to a hi amp draw from a fault lock , depending on the country that you are in you will need to find the fuse for the central locking , for european cars the fuse will be #57 or #72 it will be a 15amp fuse that will nead to be changed to a yellow 20 amp fuse , once the blown fuse is replaced , insert the romote key in its slot and turn the ignition on , then remove the key , open and close the drivers door and the central locking should then work , if this fault re-occures then 1 or more door lock will nead to be replaced, hope this is of some help , regards mark.

you can take out the back seat and gain access to the trunk

Turns out the problem was a broken wire at a junction below the carpet below the drivers seat. Took my mechanic 4.5 hours to fix it nightmare had to take seat out handbrake lever etc to get to it!!

It won't be a deadlock issue, I bet my last dollar it will be a latch fault as they are quite common but before spending money it could be a programming error. I would advise getting plugged into something like Bosch KTS or Durametric to view the system for faults.

The security key is used to prevent theives from stealing your vehicle. There should not be any way to disable or overide this feature, otherwise it would be pretty useless as a security feature. Probably the only way that that you are going to be able to get you car started again, is to have it towed to your local dealer and have them make you a new key and have it programmed to your car. I will not be cheap. You can also call your dealer and find out if there is another possible solution.

Deep joy. This can be a royal pain. The only way I have successfully done this is to put a battery charger on the car overnight, locked, and then when the battery is sitting at about 15v unlock it with the remote - when the lazy deadlock is stirred into action. It can take a couple of attempts. It really is incredibly difficult to get to. Otherwise, its most easily a case of breaking the unit...though you could try taking the leads off and applying 18v to the solonoid directly. That was my next move, but never needed to get there. You can however stop the deadlock from locking, by cutting one of the wires, test using a multimeter which one is live when you arm the alarm/deadlock the car. Thats also the one to apply 18v to if you want to.

actuators working on all four

locking module could be out of sequence after the one door repaired

drop the vw back into the place where the door lock was replaced
