Is lock cylinder in door 100% same as ignition?

[MrSlacker]

Long story short, i broke my fucking key (2 days after locking them inside the car). I don't have the title yet so can't go to BMW to get it cut from VIN. I had a key made from my broken one and it opens ALL LOCKS, but does NOT turn in ignition. A locksmith can make me a new key if I give him the lock itself. I can't remove the ignition cylinder without a key so I took one out of the door. So my question is this:

Is the lock in the door 100% same as in ignition?



Thanks

[MrSlacker]

Locked the doors by accident with keys inside while battery was out.

Obivously it's not in your case since it's not working. My car came with 2 keys from previous owner as well. I bought a new ignition lock cyl with cut factory key from the dealer, and then had a local locksmith re-key the doors/trunk to match.
