How To Drill A Pin Tumbler Lock
——————————-

Sometimes a malfunction in the lock will prevent it
from being picked.
Drilling a pin tumbler lock is a less destructive means of opening the
lock
without the key than forcing the cylinder. Almost any type of drill may be
used,
including a hand operated drill, but the small one-quarter-inch electric
drill is faster. The
bit size is not of great importance, but the small bit
will make the task easier when using a
hand drill. Normally a 1/16 to 1/32-inch
twist steel drill bit will do the job.

Make the hole just above the lower tumbler pins near the shear line. Once the
hole is drilled
to approx- imately one and a half inches, take a tension wrench
and turn the plug toward the
unlocked position. If the plug refuses to turn,
take a thin stiff section of wire and push the
upper pins above the shear line
to rotate the lock open.
