Lucky LineポーチキーHider XL、ブラック(91301)

I've been looking for something like this for a long time. My car has no place to put a magnetic key holder. I had taped a spare key inside the wheel well and it stayed there for a long time but I was always worried that it would come off. This one is just perfect and I found a good place for it.

We've had this under the back bumper of a car for over a year, replacing a magnetic type that was always a struggle to find a good location. I like that the pouch is big enough for any type of car key, has very strong velcro, and its companion fabric strip sticks really well to any flat surface. After installing it I felt confident that it would hold in place no matter what, but took someone else's advice and put in three junk keys and drove around for a week just to be sure. Now I check it every 4 months or so, but after two New England winters and plenty of jostling, I don't worry at all, and I'm about to get two more for our other cars. In the photo you'll notice I put a small triangle of white duct tape on it to make it easier to see when peering underneath the car - completely optional, but it does make it easier to spot.

Sturdy, thick. Holds spare key stuck to the underside of car's license plate in case of lock out.

Works okay, wish it was a bit biggier tho.

You need a little patience installing it. First, the bolts used from the unit to the car must line up with the ones used to bolt the license plate to the unit, and this makes it a little tight to get wrenches/sockets where they need to be. Also, it would be nice if the "open" position (license plate hinged upward) would have a "stop" position, where the plate would hold itself up. These two issues make it a little tricky to install, but if you are persistent, it will go together just fine. I chose to use a very thin weather stripping foam with a self-adhesive inside the key compartment, to keep the key from rattling around. I also put a small piece of this foam between the unit and the license plate, to keep the plate from rattling when the car hits bumps. All-in-all, I'm very satisfied with the product and the idea. If it works well with the one car, I'll be installing on all of my cars.
