Door Lock Cylinder

I'm looking for anyone who has replaced a door lock cylinder. I'm pretty sure this would be the kind of thing I can handle (but advice and tips are welcome). I've got the Haynes book, tools, and plenty of other experience inside the door and mucking around various parts of my car (98 Outback).

The dealer and my local shop both say $200-ish for the door cylinder replacement, but the part is ~45 so it's attractive to do it on my own and just have the locksmith key it to match the others before I put it in. First question: Do these sound like good numbers or should I look for parts at other sources?

A little background: this was damaged by an overzealous player my wife coaches who tried to open the lock with the wrong key (the key for our Jeep). Upon meeting resistence rather than trying another car-looking key she apparently figured more muscle was the solution and kept wrenching away.

The bottom line is that neither her key nor my key now unlocks the drivers door. Both keys unlock everything else and start the car fine so it seems to be the cylinder itself. I don't know about how these things can break so is there a change a little lube and shaking would help or is it surely bent beyond function?

In the mean time we're unlocking the doors from the passenger side or with the flaky key-fob (the other item on the todo list).

Thanks in advance,

Andy
