Getting locked out of your car or home is an incredible inconvenience, but the best magnetic key holders for cars can help you avoid calling a locksmith if — OK, when — it happens. They tuck under your car (or any other magnetic spot) and hide a set of spare keys that you can easily access in case you get locked out. Available in a variety of sizes, these key holders are ready to conceal your spares for when you need them most.

How to choose a magnetic key holder for your car

While there aren’t too many variations on the trusty magnetic key holder, there are a few specs to look for to find the perfect one for you and your vehicle:

  • Make sure the magnetic key holder you choose has the interior dimensions necessary to accommodate the size of key or keys you’d like to store. From standard metal keys to keys with large plastic fobs, there should be a size that will work for you.
  • Many magnetic key holders have a simple slide closure, but for extra security, consider one with a combination lock.
  • If you’re in search of key holders for multiple cars or hiding places, think about getting a multipack so you can meet all of your key hiding needs in one fell swoop.
