I think you’re on the wrong website, this is a diesel engine forum, you should check out vwvortex.com.
That said, what do you mean by “dead locked”? Do you mean it’s stuck locked, or do you mean someone installed a deadlock like you’d find on a house door?
If the lock isn’t turning, try putting some oil on your key. You might need a new lock cylinder which can be replaced from the inside of the car.
If the lock turns but doesn’t unlock the door, the module is probably bad, which is also replaced from inside the car. Could be a wiring issue too.
If a deadlock was installed on your door, remove the deadlock.
