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

Car Key Lock Box Design Considerations

A car key lock box is a straightforward gadget that allows you to store your possessions securely when you’re away from your vehicle. 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. You must consider the grade and strength of the materials used and how much protection they offer.
