Nite Ize Hideout Magnetic Key Box - Waterproof Key Hider - Magnetic Key Holder & Box - Waterproof Key Storage for Spare Keys - Black, Extra Large...

This key case is large enough to store my car key fob and does have a strong magnet to keep it safe when stored on you car. Very durable case.

This is a great hide a key. My car has the key in the fob. So I needed a larger hide a key. This item fit the bill. The size was great. Very strong magnet and easy to use. You wont be disappointed.

The media could not be loaded. Product: XL In pictures/video - Subaru key fob and aftermarket car starter fob. ***ONE MONTH UPDATE**** - Got this just in time and it saved me from what could have been an emergency situation. I brought my dog to Lowes and after being outside for a while he was getting hot. I loaded him into the car so I could get the AC running soon and put some plants in the trunk. I accentally left my keys in the trunk of the SUV, and when I closed the trunk, the car locked. I was frantic because it was over 90 degrees and my already hot dog was now locked in the car windows up. I then remembered the second key tucked away in this case and was able to use it and open the car. It saved my dog's life and kept me from having to break/replace a window. This key case stayed securely attached to the underside of the vehicle frame through maintained dirt roads, long road trips, super gnarly storms with hurricane force wind gusts, and minor street flooding from severe storms. The key fob worked perfectly with no issues and was still dry. ---------------------------- Pros: - Fits a standard key fob (3.75 in L) no problem or is wide enough for an after market car starter fob - Magnets are super strong and stick easily to the frame of a vehicle without need of metal plate and requires effort to remove (nice and secure) - metal plate is great if needed for storage on a non-ferrous location - water/dust proof checks out so far - water stops at seals - clip for opening and closing is very secure - hole for lanyard is built in should you want to take this bring this to adventures in the water Cons - Magnets are very strong and may even attract to items within the case. Unknown if this will affect the electronics of the key fobs long term, but had no issues with key fob still working in the short time after it was in the case (will update review after time has passed) Other: people complaining about keys not fitting probably have the original size and may have failed to measure the length of their keys/fobs before purchasing (I failed to measure the first time and got another brand that ended up being too short by a 1/4inch, which is why I opted for this one).
