A jimmy proof lock unlocks like almost any other lock. The difference is that the design of this lock is that it is a surface-mounted deadbolt. Instead of having the bolt be secured within the door and its jamb, the bolt hooks into a separate mount that is placed on the exterior of the frame.

You would insert a key to unlock the door as normal. Unlocking the door from the inside requires turning a handle, as with a standard deadbolt.

Jimmy Proof Lock Unlocking Benefits


How is a Jimmy Proof Lock Different?

Jimmy proof locks were invented in the early 20th century to prevent break-ins from occurring in urban environments. With a flat side and oval shape, the lock works by having a bolt that slides vertically into a strike plate when the door has been fully closed. The strike plate for the lock is then attached, via self-tapping screws, to the door frame.

These locks typically require a 1.25-inh hole in the door and nothing more to complete that portion of the installation. In comparison, a deadbolt often requires a minimum of 4 holes in the door.

  • They are difficult to unlock without a key. A jimmy proof lock unlocking process prevents unauthorized entry through drilling, snapping, picking, and bumping. You will need the key to unlock the door.
  • There is no spring mechanism. Jimmy proof locks are like deadbolts in their operation. That eliminates the spring mechanism that can be triggered in other locks, making it a more secure option for the home.
  • It offers vertical locking. Even a standard deadbolt offers an access point between the door and the jamb that could be targeted by a committed bad guy. The vertical locking design of a jimmy proof lock eliminates this option, which helps to prevent the front door from being pried open.

A jimmy proof lock unlocks from either side of the door, no matter which way the door may swing or open.
