TOSICAM Magnetic Key Lock Box - 4-Digit Combination, 3x N52 Magnets, Weather-Resistant

The TOSICAM 3xN52 Magnetic Key Lock Box is a compact, weather-resistant lockbox that hides keys and small items securely using a 4-digit combination and three powerful N52 magnets.

This compact magnetic key holder combines a resettable 4-digit lock with heavy-duty rare-earth magnets and a sealed shell to protect contents from weather and theft. Designed for vehicles, homes, rental properties and outdoor use, it offers two installation methods — a detachable shackle for hanging and a magnetic base for attaching to metal surfaces like car undercarriages. The interior fits most standard keys, fobs and small tools while the exterior resists rust and moisture for reliable performance in varied environments.

How secure is the 4-digit combination and can I change it?

The lock uses a four-wheel dial system that creates more than 10,000 possible combinations, letting you set a unique code. It ships preset to 0-0-0-0 and you can change the code in a few simple steps without special tools.

• Over 10,000 possible 4-digit combinations for varied access codes.
• Factory default code set to 0-0-0-0 for easy first use.
• Resettable mechanism allows periodic code updates for added security.
• Mechanical dials—no batteries or electronics to fail.

Will the magnets hold the box under a moving vehicle?

This model includes three N52-grade rare-earth magnets engineered for high magnetic strength, giving a firm attachment on ferrous surfaces even with vibration and light movement. It’s intended to remain secure under cars, RVs and trailers when mounted to clean, flat metal areas.

• Three N52 magnets deliver strong pull force for stable adhesion.
• Works on clean, flat steel undersides and vehicle frames.
• Not recommended for painted or highly uneven metal without testing first.
• Detachable shackle option available for non-magnetic mounting.

Can this lock box stand up to rain, snow and outdoor conditions?

The TOSICAM key box features a sealed housing and corrosion-resistant materials to help keep internal contents dry. It’s built for outdoor locations like garages, pool areas and cabin exteriors, but extreme prolonged exposure or submersion should be avoided.

• Sealed shell reduces water and moisture ingress.
• Rust-resistant construction for longer outdoor service life.
• Compact profile sheds water and minimizes exposed seams.
• Best used in sheltered or routine-exposure outdoor settings, not underwater.

What fits inside and how easy is it to carry or hide?

Although compact, the interior is sized to accommodate most car keys, key fobs and small multi-tools, offering a discreet storage option that’s easy to conceal. Its small footprint and magnetic mounting make it suitable for under-vehicle hiding, door knobs, or fixed metal spots where it stays out of sight.

• Internal space approximately 1.06" × 2.2" × 3.43" for common keys and small accessories.
• Slim exterior profile for hidden placement on vehicles or fixtures.
• Includes detachable shackle to hang from door hardware when magnetism isn’t practical.
• Lightweight for portability while robust enough for repeated outdoor use.
