Guard Security 1303 Jimmy-Proof Single Cylinder Deadbolt Door Lock Bronze

Exterior door security upgrade

The Guard Security 1303 is a jimmy-proof single cylinder deadbolt built for exterior doors that need keyed entry with an interior thumb turn. Its solid brass cylinder resists daily wear and the rust-resistant construction handles regular exposure to the elements. A bronze finish provides a warm, traditional appearance that suits classic home styles. Hardware and instructions are included for straightforward installation.

Replaces vulnerable surface-mounted locks

This deadbolt upgrades older or damaged jimmy-proof hardware where the interlocking design is worn or missing. The jump is worth it when an existing surface lock shows signs of forced-entry damage or when the cylinder no longer turns smoothly. It also replaces basic latch-only hardware on doors that previously had no deadbolt at all. The included flat and angle strikes cover common frame preparations without extra parts.

Fits standard surface-mount preparations

The lock mounts on the interior face of the door and engages a strike on the frame, requiring no deep mortise pocket. It works with typical wooden or metal doors where a surface-mounted deadbolt is the intended application. The single cylinder layout frees up the interior side for keyless egress, which speeds up emergency exit. The bronze finish coordinates with matching door hardware for a consistent look.
