This one is making me lose some sleep.
We do a fair amount of Medeco installation and service, but this one is driving me nuts. We took a service call for a lockout on a Medeco Bodyguard. The customer had the key, and yes, it was the right key, the key would go into the lock with no problem but not turn. (the lock was about two years old). My locksmith that was on the call lubricated, probed to make sure all the pins were free, tried several different keys, tried the keys NUMEROUS times, still no luck. We were left with no choice but to drill out the bodyguard (oh what fun!).
So after re-installing a new bodyguard and cylinder (about three weeks ago), we get a call today that the customer is having the same problem. I am totally bewildered over this. The lawyers office where this was installed feels that it might be sabotage (which wouldn't surprise me being that it's a lawyers office). If it is sabotage, how? The only thing I can think of is a pin turned somehow but twice on two different medeco cylinders in the same place? Is the building possessed?
