Meterk B-811 Key Lock Box

The Meterk B-811 is a wall-mountable key safe with a resettable four-digit combination that yields ten thousand possible codes. Its hardened steel lock cylinder and thickened ABS housing resist hammering, sawing and corrosion, making it suitable for outdoor use on homes, offices or rental properties.

Removable Shackle and Mounting Kit

A removable shackle lets you hang the box on a door knob or similar fixture without tools. For permanent placement the package includes four screws and four expansion plugs so you can bolt the unit to any solid surface such as brick, concrete or wood.

Simple Setup and Common Issues

Setting a new code is done by opening the box, moving the internal reset lever and dialling your chosen numbers. The dust-proof cover protects the dials from grit, but if debris enters the mechanism the dials can stiffen; periodic cleaning keeps them turning freely. Ensure the shackle is fully seated before locking to avoid alignment problems.

Questions about this item

How often will the combination mechanism need lubrication or internal parts replaced?

The lock uses an aluminium-alloy internal structure and hardened steel cylinder designed to resist jamming and rust; no scheduled lubrication or part replacement is mentioned by the manufacturer.

What is the first limit reached when the box is left outdoors in continuous sun and rain?

The 0.18-inch thickened ABS housing with powder coating is rated waterproof, dust-proof and corrosion-resistant, so the primary limit is the 3.35-inch maximum key length that fits inside.

Does the lock box generate any heat or noise when mounted in direct sunlight all day?

It has no power requirements, electronic components or moving parts that produce heat or audible noise during extended outdoor exposure.
