Our take on the Iron Lock Portable U-Shackle Key Lock Box

The Iron Lock is a shackle-mounted key box: a metal body with a zinc-alloy 4-digit combination lock that hangs over door knobs, gates, fences and railings instead of being screwed to a wall. The U-shackle is removable, so you can move the box between properties, and the code resets with an internal A/B lever. It is small inside — about 2.5 by 2.7 by 1.4 inches — so it holds a spare set of keys, not a bulky fob ring. Against wall-mounted rivals it trades capacity and permanent mounting for portability, and buyers describe the metal body as feeling premium and secure.

About the Iron Lock Portable U-Shackle Key Lock Box

The Iron Lock Portable U-Shackle Key Lock Box is a compact key box with a heavy-duty metal body and a zinc-alloy lock. A hardened, scratch-resistant outer shell protects the keys and surrounding surfaces. The body resists water, sand, and salt, and it is built to deter theft and tampering.

A removable rigid U-shackle hangs the box on door knobs, gates, fences, and railings. The shackle is wrapped in rubber. The box is shackle-mounted, so no wall drilling is needed, and it can be moved whenever you want.

The lock uses a 4-digit combination that can be reset. To change the code, use the internal A/B reset lever. This lets you share access without handing over a key. The interior holds a spare set of keys.
