How It Works
The Magnetic Under-Car Key Box uses two screw-in neodymium magnets embedded in the lid. These magnets provide exceptional holding force (a tested separation force of approximately 50 lbs), allowing the box to remain secure even when your vehicle is in motion over rough terrain. The housing seals against moisture, and the interior cushion protects the stored items. Attach it to a flat metal surface under the vehicle and hide your spare key or valuables.

Frequently Asked Questions
- Is the box truly waterproof?

- Yes — the internal dimensions allow room for a mini GPS tracker alongside a spare key or other small items.
