I had my door lock fail on me. I live in the DC Metro area, was in Philly for business parked in the garage at the company condo. I went downstairs to the garage to put some luggage in the truck and the key worked fine. I came back 5 minutes later and couldn't unlock it.
I tried spraying dry lubricant into the lock, jiggling the key all sorts of ways, and tried to force it with no luck. I ended up taking a taxi to the nearest Rover dealer (Cherry Hill) with my vin number. They cut me a key based on the vin and another based on the key I had. Neither key worked.
I called AAA, they sent a truck out and I had to stop the guy from trying to pump the door open because I was afraid it would go into super lock. They sent out a lock smith and he couldn't cut a key to work.
About 6 hours later I figured there was no way I was going to have the truck towed out without breaking a window, disconnecting the battery to stop the alarm from going off and potentially having to break the steering wheel lock to get the truck out of the garage (the rover was too tall to be put on a flat bed and towed out).
I drilled out the lock and turned the tumblers with a flat head screw driver. My key that didn't work in the door still worked in the ignition.
I got a new door handle, had a good lock smith fit the key, and its been working ever since.
