Hide A Key Magnetic Key Holder Under Car - Hide A Key for Your Car So You Never Lock Out - Plastic Magnet Key Hider to Store a Spare for Your Home, Storage, Office, or Vehicle - 3 pack - by RamPro

Great for hiding a spare key to keep you from being locked out of your vehicle

As expected

Too hard to open. The box cover is too tight to open and close.

Strong magnet 🧲 and secure hold.

These are so great! I use them on all my vehicles. Use the jumbo ones to hold more than 1 key. Good strong magnet that is powerful enough that you will have a hard time getting it off haha.

Only good for standard keys, not for ones with transponders. I thought it would work because it was long enough but part of the length on the inside is used for the magnet. If you have a car key with a large remote on the end or even one with a pop-out key, it is most likely this will not work for you. It is too thin and the sliding door will not close. I used one for a dummy key that only opens the car door. Didn’t have any trouble sliding the doors open. The magnets are strong, you just have to find a real steel piece to stick it to. Once you place it, try pulling it off and keep in mind, these can slide off as your car travels on bumpy roads. Try to find a flat piece of steel on the cars under carriage.

The product feels like it is well made. The magnets are heavy enough to hold onto the side of a refrigerator with no concerns. The size is big enough to hold two or more keys. However, as delivered, the sliding door is impossible to open without help from a flat head screwdriver or a pocketknife. I ended up using a dremel tool to thin out the door sliders on both sides of all three. They all work suitably after the additional treatment.

These are great. Small and easy to hide. Magnets work great. Would recommend.
