The roof box is an essential accessory for going on vacation and storing your belongings. You have chosen a safe suited to your needs, equipped with an efficient opening and closing system. Yes, but what if you lose your safe keys? We explain how to open a roof box lock without a key.


Installing a roof box on your vehicle leads to more excellent air resistance and inherent noise. To limit these effects, make sure to invest in an aerodynamic roof box that is correctly adapted to the size of your car. Indeed, not all roof boxes have the same volume or dimensions. On average, from 300 to 600 liters, the choice is vast for lengths ranging from 100 to more than 200 cm. Thus, you can invest in a trunk suitable for city cars and SUVs.

However, there are several different roof box models, each with its opening and closing mechanism. You can therefore opt for:

A roof box with a central lock

The closing and opening of the boot are done at several points simultaneously.

A roof box with a secure lock

It is necessary to lock the roof lid to retrieve the key. Therefore, it is not possible to forget your keys or lock this safe incorrectly.

Similarly, opening the trunk can be done in two different ways. You can then get:

A roof box with an assisted opening: Opening is done automatically by inserting the key into the box’s lock.

A roof box with bilateral opening:  The opening is on both sides of the box, facilitating the loading and unloading of its contents.


You use a roof box regularly, especially if you go on vacation often or on a more occasional basis.

Several instructions must be followed when using it:

  • Closing the roof box must be easy to do
  • The load must be optimally distributed within the trunk
  • The heaviest objects should be positioned in the middle of the trunk so that they cannot move
  • The maximum permissible load weight for your vehicle must not be exceeded.

It is essential to follow these rules to the letter to travel with a roof box without danger.


Have you lost the key to your roof box and need it to go on vacation? It’s boring. But rest assured, there are several methods to open a roof box despite the absence of a key.

Change your roof box lock

Call a locksmith in Tampa to replace the lock. If you don’t have the key, you need to open your roof box lock. It will then be necessary to drill the barrels to install new ones. After that, you can contact the manufacturer to obtain a new lock copy. If you do not have the skills to change it yourself, do not hesitate to call an external service provider.

Force the lock of your roof box

If you’re a do-it-yourselfer, you can open your roof box lock with just a bobby pin and a pick. To do this, put the hook in the lock to be stable. Then insert the pin into the top of the lock. Then, all you have to do is turn the hook in the door opening direction until the lock opens. If this technique is not recommended to force the lock of a front door, some roof box locks will not resist it.

Get a spare key

If you rivet the roof box, you cannot replace it. However, some manufacturers allow you to obtain new keys from the serial number engraved on the roof box lock. Are you in this situation? Contact your safe’s manufacturer, and you’ll get a new key in less time. It is ideal if you have lost your key or want to get a spare key.
