Step 1
Place a piece of masking tape over the lock. Press it down firmly, so you can see the small circular area in the center of the barrel. The masking tape will minimize residue from the lock flying out during the drilling process.
Step 2
Drill into the lock at medium speed for approximately 3/4 inch. Use a 3/16-inch drill bit and keep it as straight and level as possible, while drilling.
Step 3
Continue drilling at a slow speed until you feel the drill bit catch the latch bar, which will pop open the lock.
