Magnetic Hide a Key Box for Under Car - Waterproof Secure Storage

In this review the Gorilla Box magnetic hide a key box is judged on convenience and reliability for people who need a discreet car key solution. The bottom line: it is best for vehicle owners who want a simple, durable way to store a spare key under a car without fumbling for lockboxes or worrying about accessibility. The single biggest reason to buy is the box's strong magnetic hold, which keeps the case attached to the undercarriage so the key is there when you need it.

Key Features

• Convenient and Secure: The box provides an easy method to hide a key under a vehicle so a spare is accessible without carrying it on your person.
• Strong Magnetic Hold: A powerful magnet secures the box to the car frame to reduce the chance of it falling off during normal use.
• Undercarriage Placement: Designed for mounting under the car, the box sits discreetly out of sight to deter casual discovery.
• Waterproof Air-Tight Design: The case seals to help protect keys from moisture and road grime while mounted under the vehicle.
• Reliable and Durable: Built to withstand regular use, the Gorilla Box aims to provide long-term key storage that holds up to outdoor conditions.

Who It's For

The magnetic key box is ideal for drivers who need a hidden spare for emergency access, family members sharing a vehicle, or homeowners who prefer not to carry a backup key. It suits sedans, SUVs, and trucks where a metal undercarriage area is available for mounting the box with the magnet.

It is less appropriate for owners of vehicles with little exposed metal underbody, cars regularly serviced on lifts that might dislodge attachments, or users who require keyless remote storage that includes batteries or electronics. Those seeking a combination lock or visible wall-mounted key cabinet should look elsewhere.
