BMW Repair: Car Locks, bmw 3 series, 7 digits

Question
My BMW 3 series has locked itself,the key isnt working and the barrel on the drivers side appears to be broken and I cannot access my car.  How can I get into my car?  Your help would be much appreciated.


Answer
would people submitting questions PLEASE give us enough info to work with as in model, year and the last 7 digits of the chassis number.

Back to your question, it SOUNDS like an e30 with mechanical deadlock on the drivers key that electronically deadlocks the other doors/ boot.

IF the drivers lock has turned 90 degrees(horizontal) its in deadlock.

If so, make sure you have a spare key first.
Spray a lot of wd40 into the key hole on the drivers door.
Now for the fun part, put a mole grip on the key and with gradually increasing pressure turn it to the open position rocking it a bit maybe.

Should work, if its not an e30 try putting the key in the pass door,lift the handle then turn the key.

hope that helps
