Lucky LineExtra Large Magnetic Key hider Case Key Holder for Large Keys (9121)

it says large it’s really large… But worked very good with the new type of car keys… Very good magnet force

This was purchased for my oldest son who has enjoyed this. He's always doing something to his truck. But i am happy as long as it is used and works. He definitely is happy.

Great magnetic grip.

I bought the XL size and it was perfect for my truck key, my locking gas cap key, and a house key.Pro's: Very strong magnet that held up to heavy off-roadingCon's: One of the magnets rattled a lot (Had to shim it with a piece of rubber). This is why I gave it 4-stars)I wrapped all of my keys together in a paper towel, put the bundle in a small zip-loc baggy, and then put it in the box. That way, the keys are protected from the elements, shock, and they don't rattle around loose in the box. I also use a piece of Gorilla tape (But duct/electrical tape will do just fine too) to secure the sliding lid to the housing to ensure that it will not open accidentally. Overall, I'd definitely buy it again.

Works well and the magnets are very strong.

I have several of these on my SUV in case one or more fall off. They don't feel as strong as neodymium magnets but I've never had one fall off. Have had to use one of them just once... and it was a lifesaver! I'd suggest putting your keys in a small thick poly bag that seals and then give a healthy squirt of WD40, then seal the bag and put in in the case. The keys, years later, come out clean with no corrosion or road dirt and sand on them. It's an extra step but 100% worth it.

My Honda key includes the remote lock so it is extra long. It does not fit inside this case. I can fit my Frontier key in it but not the remote locking for. Fortunately I can lock and unlock that vehicle with just the key. Magnet is very strong but I am not sure about the sliding cover staying closed when driving the vehicle. So might not be handy for carrying spare in case of locking keys in vehicle.

Now I must say I did not use this for a large car key! It is used for a regular store or house key, so would not be under a tire well or bumper so I can not tell you if it stays put or not under those conditions. But it stays hidden where I have it and has not been jarred loose. the box is actually big enough for several keys so it you needed more than one lock and hidden keys for each, this is big enough. it is easy to open and easy to put back in place, no complaints from me.
