This Killer Key Disables Any Lock It's Placed Into

Are you a landlord looking to keep you tenants out after evicting them? A law enforcement official looking to keep out squatters? Or just a prankster looking to screw over a friend or foe? This killer key might be for you. A killer key is a key that you can push into a lock and will instantly and permanently disable the lock. The door can still be opened from the inside, but from the outside it's rendered useless and the only way to get in is to drill the lock. To use the key, simply slide it into any Kwikset lock, and push sideways on the bow of the key which will easily break it off and leave the teeth of the key locked inside blocking other keys from entering.

You can get a killer key that fits into Kwikset locks, as well as Schlage locks, which according to the manufacturer, 90% of all locks in the United States use either Kwikset or Schlage locks, so your odds are good if you're looking to use this killer key in one of your locks.
