Ok... This is going to be fun and result in a lot of destruction and probable personal injury.
The lock on one of our spare rooms is broken and we are now locked out of it.
The lock is the typical door knob with a 'Yale key' and a button on the inside to engage the locking mechanism.
The key(s) do not work.
A locksmith has failed to pick the lock and has said the tumbler inside the lock is too stiff or broken to move.
There is no possibility of opening the door with the old card trick as the gap is too tight to get anything in.
Possibilities seem to be....
1) kicking the door in. (probable severe door and frame damage)
2) whacking the outside knob off and attempting to force the mechanism, but I think the impact will fuck up any chances of manipulating it.
3) cutting a hole through door and reaching through and opening it from the inside (new door needed)
4) use my angle grinder to cut outside knob off, then trying to force mechanism.
There is no way to get inside the room from the windows (2nd floor with security grills over them)
Any recommendations?
