What is a car key lock box?

A car key lock box is like a mini safe where you can store your car keys while doing activities such as surfing or swimming. You can generally securely attach the lock box to your car like a padlock and can lock and unlock the box using a combination code.

A car key lock box is a handy accessory if you need somewhere to store your keys while surfing safely. Of course, you can also stash cash, credit cards, or other valuables in these boxes.

Car Key Lock Box Considerations

A car key lock box is a straightforward gadget that allows you to store your possessions securely. But, first, you should consider a few core features to ensure your car key lock box meets your needs.

Understanding these features will help you choose the perfect car key lock box.

  • Shackle: The shackle is what locks the box onto your car. There are several options, such as a padlock-style shackle or a chain shackle. Some lock boxes also allow you to remove the shackle so the box can be wall mounted.
  • Box: Your lock box must have a compartment large enough to store your keys. Always pay attention to this size to ensure it’s big enough for whatever you want to keep safe. 
  • Lock: The type of locking mechanism is also an essential consideration. In most cases, a locking code secures the lock box. 4 digit codes have 10,000 possible answers, which will undoubtedly keep your lock box safe.
  • Durable materials: The lock box needs to be strong if it’s going to protect what it contains. It should also be made of salt-resistant, weather-resistant and rust-proof materials – especially since you will likely be parking near the beach. Pay attention to the grade and strength of the materials used and how much protection they offer.

Locker BOXX

  • Extremely strong magnetic box
  • Made from polymer hard plastic
  • Waterproof
  • 3.25″ L x 1.75″ W internal dimensions’

This car key lock box is a little different. It’s not a classic combination lock box, but rather a magnetic locker box that doesn’t come fitted with a lock. The box has actually been designed to hold GPSs to track vehicles, but it also works perfectly as a car key storage box.

The magnets are incredibly strong and convenient to use. You just stick them onto your car and they will hold up even while driving on the bumpiest roads. The box itself is solid and very convenient to use. 

The downside is that the box doesn’t lock, so it will have to be well hidden. It’s also quite small, and won’t fit all car keys. 

That being said, it’s a seriously helpful box to stash away your keys, GPS, or even to store a spare set of emergency keys when you go on a road trip.

Why I use a car key lock box when surfing?

A car key lock box became an essential part of my surf accessories after my partner’s car got stolen while surfing a few years ago. Previously he had hidden his car key in the bushes, with a towel on the beach, or under his car while surfing, but when a robber stole his car, we knew we needed a new solution for keeping our car safe!

On that particular day, he hid his car key on the tyre of his limited edition Lexus. So when he came out of the surf, initially he thought he had forgotten where he parked his car!
