## Description

Upgrade Large 7.3''x4.2'' Magnetic Key Holder Under Trucks Car,Car Key Fob Holder,Heavy-Duty Magnetic Key Box Under Car,Hide a Key,Strong Magnetic Key Hider Outside for Hiding Keys【Splash Resistant】

## Features

- 7.36'' x 4.25'' Large Capacity - The magnetic storage box can fit your big keys! Large capacity meets the multiple storage requirements, such as airtag, door keys, car keys, USB drive, watch, cash, etc! The dark color is perfect because it makes it much harder to see depending on where you place the key holder.
- 4 Neodymium Magnets - With 4 strong magnets, the magnetic key holder can be attached to nearly any metal surface with a separation force of 50 lbs. If you attach this outdoor key hider under your car/truck, no worry about it being lost even if you drive at high speed or on Undulating terrain. A secret hidden spot that only you know!
- Splash Resistant - There are four latches and a self-aligning retainer to ensure the hidden key box doesn't come open unless you open it intentionally. The latches are simple but strong. The magnetic key hider is splash-proof, we suggest putting your key fob (or other valuables) in a zippy bag before inserting them in the hidden key box if you plan to mount it on your vehicle and go driving through puddles or wet conditions.
- 2 Open Holes - There are 2 holes at the top of the box for zip ties or maybe a very thin chain lock, providing an alternative way to hide the magnetic key box if magnetic attachment isn't possible.
- Removable Padding - The magnet key holder for truck has padding on the inside so the things inside can't shake and rattle around. please open the storage box up for a LOT more storage if the padding isn't needed. There is no adhesion on the padding. The key case is durable hard plastic which would resist wear and tear.
