Master Lock Magnetic Key Holder, 1 Pack, Black

The Master Lock Magnetic Key Box is an absolute must-have for anyone needing a discreet, reliable spare key solution. This little box is a masterpiece of simple utility, offering peace of mind without any complicated mechanisms. ​Its primary strength lies in its outstanding magnetic grip. The heavy-duty magnets are seriously strong; once you attach this box to a clean, flat metal surface (like underneath a car chassis or on a gutter drainpipe), it stays put through bumps, road vibrations, and even car washes. You can trust that your spare key will be exactly where you left it, regardless of the weather or driving conditions. ​Another major selling point is its perfect concealability. The compact, dark casing is designed to be tucked away out of sight, and when placed strategically, it’s practically invisible to a casual observer. This level of discretion is crucial for security. ​Inside, the box features a surprisingly generous compartment. It's spacious enough to easily hold multiple standard house or car keys, or a single large electronic fob, making it versatile for different household needs. The hinged lid closes tightly, creating a weather-resistant seal that keeps the contents dry and protected. ​Overall, the Master Lock Magnetic Key Box does one job—hiding and securing a spare key—and does it perfectly. It's a high-quality, practical item that provides excellent security and convenience for a low cost.

I am extremely pleased with this Master Lock magnetic key holder! The strength of the magnet is impressive and gives me complete confidence that it will hold securely while I’m driving. It’s surprisingly roomy, accommodating not just my keys but also my key fob and another small essential without feeling cramped. Opening and closing the holder is a breeze, yet it requires just the right amount of force to ensure that it stays shut—this reassures me that my keys won’t accidentally fall out while I’m on the road. I love the peace of mind it provides, especially when I’m in a hurry. I was so impressed that I’ve already added another one to my cart for added convenience! If you’re looking for a reliable and spacious solution for keeping your keys safe while driving, I highly recommend this product. It’s been a game changer for me! Worth every penny spent! Used water bottle for reference of size.

Was larger than I expected, which is fine. Very powerful magnet as well. Is tricky to open, people with arthritic hands might really struggle. It's well built.

Room for more than just a key or two. Sturdy construction. Lid opens in a way which protects against water, dirt, etc intruding. Lightweight with a strong magnet. Great for stashing a key or more.

I went on a solo road trip and wanted to stash my spare key fob in case I lost my keys since I was so far from home. I was really nervous about using a new product while on the road because if it didn’t work, I would lose my only spare (and have to pay $100+ for a new one), so I decided to not put my key in it for the first day. I drove 400 miles the first day to Sand Dunes, National parks and forests, highways up in the mountains, over dirt roads, construction zones, 20 miles of VERY bumpy and unpaved mountain backroads, etc.. Literally experienced so much terrain while it POURED rain on the mountains passes, and the next morning I checked to see if it was still there. It was splattered with mud, and still secure in its exact spot. No shifting or movement at all. I put my key in it and proceeded on the remaining 5 days of my trip. It never shifted, fell off, or broke in any way. I would highly recommend this as it’s large enough to fit my key fob and it stays put! I have a 2013 RAV4. Also, for $5 it was such a great price for the quality you get.

For what's on the market today, this is the best. I wish I could give it 4.5 stars, just because I always think there's room for improvement. Others have outlined the pros and cons quite well, but I'll do a quick summary. - No outside print or labels, making it less obvious when on a car - Solid construction - still plastic though - Good open/close sliding mechanism with a "click" to snap it shut - Bigger size - all of our car and SUV keys fit no problem (individually of course, not the whole key ring) - Good magnet - nice size and strength, but could be more. Size is roughly 1 inch by 2 inches. The magnet is much much better than past ones I've had. But I think they could make it even stronger. Why not? They make amazing magnets these days in very small sizes. There's certainly more powerful and smaller magnets out there, so why don't they use them in their design? That said, even with the strength of this magnet, which is quite good, I wouldn't leave it on the car long term. I don't think it would fall off, but why risk it. If I'm leaving a hide-a-key on my car for long periods of time while driving I put a piece of black duck tape over it. Just a little added insurance. Ironically I've found hide-a-key boxes sitting in the road with a key in it before. So they do fall off if you hit the right bump. Plus the tape helps to ensure water doesn't get into it. I had a hide-a-key taped in a box on my frame for two years and the day I needed it I was really really glad it was still there. Plus...the last time I had to replace a key to my Pathfinder, I learned the keys have a microchip in there that is unique to the car. So you can't go have one made from a blank at the hardware store. It was expensive to get an extra key ($75), so now I don't take the chance of losing it.

Great product it stays on I’ve had it for years
