Car key safe Switzerland for vehicle key storage

Leave Your Car Key Safely with Your Vehicle
A car key safe lets you leave a vehicle key with the parked car instead of carrying it skiing, cycling or onto the water. The BELS17A is our ready-to-use compact window-mounted model. For bulky electronic keys and large fobs, we make the MLK5412A AUTO XXL ourselves by adapting a larger Master Lock 5412 and fitting our over-window mounting bracket.

Why I’ve Used a Car Key Safe for Nearly 10 Years – and Why You’ll Love One Too

I've had a BELS17A fitted to my own car for nearly ten years and have used it hundreds of times, in all sorts of situations. From skiing and cycling to paddleboarding and travelling abroad, it has become one of those simple accessories I wouldn't want to be without. These are real examples from my own experience.

Why we use a car key safe when skiing

I've used my own BELS17A for nearly ten years, including when skiing. One day at Villars, while we were putting our car key into the safe attached to the vehicle, a woman came over to ask what it was. Her partner had lost his car keys somewhere on the slopes earlier that season, causing them considerable problems. That is precisely why we use one: the key stays in the combination safe attached to the car rather than travelling around in a pocket all day. There is another advantage when we ski with others: whoever returns first can open the car, take off their ski boots, change clothes and wait comfortably out of the wind and cold.

Cycling, hiking and paddleboarding: keep electronic keys dry

On cycling and hiking days, we prefer leaving the car key at the vehicle rather than carrying it in a jacket or shorts pocket. That is even more useful when paddleboarding or swimming: an electronic key fob does not need to go anywhere near the lake. We leave it dry in the safe attached to the car. If people finish at different times, whoever returns first can use the combination to get back into the vehicle.

Airport parking at Geneva and Basel

We have also used our car key safe many times while parking at Geneva and Basel airports. Once the car is parked, we leave the key in the window-mounted safe instead of taking it abroad on holiday. When we return, it is exactly where we need it: with the car. One less thing to carry or keep track of while travelling.

A brilliant gift for anyone who loves the outdoors

Know someone who loves skiing, hiking, cycling, swimming or paddleboarding? A car key safe makes a thoughtful, practical present. It is one of those simple accessories they might never think to buy themselves, yet could end up using hundreds of times.

Spitex, home-care teams and shared company cars

We already have several customers among Spitex and home-care teams, as well as businesses with shared vehicles. Their needs were a key reason we created our MLK5412A AUTO XXL: we adapt the larger Master Lock 5412 ourselves and fit our window-mounting bracket, providing room for bulky electronic keys, fobs and access cards. Authorised staff can then access a vehicle without arranging a hand-to-hand key exchange.

Compare the two models

BELS17A
Proven standard model
The BELS17A is a straightforward choice for standard-sized car keys. Its mechanical combination and window mounting allow the key to remain at the vehicle during a day out, while authorised people can return independently. There is no app or battery to manage. Check the internal dimensions against your key before ordering.

MLK5412A AUTO XXL
Our adapted XL solution
Modern electronic keys can be too bulky for a compact vehicle key safe. Our MLK5412A AUTO XXL addresses that specific problem: we prepare a larger Master Lock 5412 and fit our own over-window bracket. The resulting safe offers more room for large fobs, badges and access cards, without requiring a permanent vehicle installation.

How it works

Fast installation
Lower a side window slightly, hook the fitted bracket over the glass, then close the window to secure the safe outside the vehicle. No drilling or permanent changes to the car are required. Before leaving, check that the bracket is seated correctly and that the window is fully closed.
Controlled access
Put the key inside, close the safe and scramble the mechanical combination. Anyone you have authorised and given the code can collect the key when needed, even if they return before the rest of the group. Change the code when access requirements change. For keyless-entry vehicles, follow the manufacturer's guidance on storing electronic keys near the car.

Especially useful for

  • outdoor activities such as hiking, skiing, cycling and active day trips
  • water-based activities where carrying the key is inconvenient
  • family and shared access when more than one trusted person may need the vehicle
  • temporary access for carers, service visits or other planned users
  • professional or shared vehicles where organised access and larger key fobs or cards are involved

Why these solutions work

Mechanical simplicity
The beauty of this solution is its simplicity: a mechanical combination, a window-mounted bracket, and no batteries, mobile reception or apps to worry about. Whether you're skiing, cycling, swimming or simply don't want the hassle of carrying a car key, you can leave it at the vehicle. And when several people are out together, whoever returns first can access the car without waiting for the person carrying the key.
Two genuine solutions for different key sizes
The most important difference between the two models is usable internal space. Choose the BELS17A for a conventional key, or consider our adapted MLK5412A AUTO XXL for a large electronic fob or access card. Measure the key rather than relying on its appearance, particularly if it has a thick protective cover.

Which model should you choose?
If you have a normal-sized car key, start with the compact BELS17A. If you have a large electronic fob, badge or access card, our adapted MLK5412A AUTO XXL provides more space. Check the actual key dimensions and the vehicle manufacturer's instructions before choosing.

Secure vehicle key storage with a mechanical code

A car key safe, sometimes called a car key lock box or vehicle key safe, allows a vehicle key to be stored in a locked container attached directly to the car.

Our window-mounted key safes for cars use a mechanical combination lock and a special over-window bracket. Lower the vehicle window, position the bracket over the glass and raise the window again to hold the unit in place. No drilling or permanent modification to the vehicle is required.

We offer two solutions in Switzerland: the compact BELS17A for standard car keys and our specially adapted MLK5412A AUTO XXL for larger electronic key fobs, badges and access cards.

Compare BELS17A and MLK5412A AUTO XXL

The best key safe for a car depends primarily on the size of the vehicle key and how the car will be used.

BELS17A is our compact, ready-made car key safe. It is suitable for standard vehicle keys and straightforward private or leisure use.

MLK5412A AUTO XXL is our larger specialist solution. We adapt the Master Lock 5412 and fit our own over-window vehicle mounting bracket to accommodate bulkier electronic car keys, remote fobs, access badges and cards.

Before ordering, check the dimensions of your vehicle key or electronic fob against the internal space available in the model.

Leave your vehicle key with the car

A car key storage box can be particularly useful when taking a vehicle key with you would be inconvenient.

  • Swimming and water sports: avoid carrying an electronic car key into the water.
  • Hiking and trail running: leave the key secured to the vehicle rather than carrying it on the trail.
  • Cycling: convenient when you do not want a bulky vehicle key in your pocket.
  • Skiing and winter sports: reduce the need to carry car keys in ski clothing or backpacks.
  • Beach and outdoor activities: avoid leaving keys loose in bags or hiding them near the vehicle.

A mechanical car keysafe provides coded access without batteries, charging or a smartphone application.

Controlled access without handing over keys

A vehicle key lock box can simplify access when several authorised people need to use the same car.

Typical applications include family vehicles, company cars, shared vehicles, vehicle maintenance and planned handovers.

Instead of arranging a physical key exchange, an authorised user can access the vehicle key using the mechanical combination code. The code can be changed when access requirements change.

For modern vehicles with larger electronic keys or access cards, our MLK5412A AUTO XXL provides considerably more internal storage space than a compact car key safe.

Window-mounted installation without drilling

Our car window key safes are designed for quick fitting and removal.

  1. Lower the vehicle window slightly.
  2. Position the mounting bracket over the glass.
  3. Raise the window to secure the bracket in place.
  4. Place the key inside and close the key safe.
  5. Secure the mechanical combination lock.

The protective backing helps reduce the risk of marking the glass. Check that the bracket fits your vehicle window and that the unit is correctly positioned before use.

The system does not require screws, drilling, adhesives or permanent changes to the vehicle.

Using a combination car key safe responsibly

A combination car key safe provides a controlled way to store a vehicle key, but no portable security product can guarantee protection against theft.

  • Keep the access code private and change it when necessary.
  • Check that the safe is correctly attached to the vehicle.
  • Make sure the key or fob fits without forcing the cover.
  • Avoid leaving other valuables visible inside the vehicle.
  • Check any relevant vehicle insurance conditions.
  • Follow the manufacturer's instructions for your vehicle and key.

Some modern electronic vehicle keys use proximity systems. Check that your key and vehicle behave appropriately when the key is stored near the car.

Can I leave my car key in a lock box attached to the vehicle?
Our window-mounted car key safes are designed for this purpose. Always check compatibility with your vehicle and follow sensible security precautions.

Do car key safes need batteries?
No. Both BELS17A and MLK5412A AUTO XXL use mechanical combination locks.

Can a car key safe hold an electronic key fob?
This depends on the size of the fob. Our MLK5412A AUTO XXL was developed specifically for larger keys, fobs, badges and access cards.

Can I remove the key safe after use?
Yes. The window-mounted design allows removal without permanent installation.

Which car key safe is best for swimming or hiking?
For a standard-sized car key, BELS17A is a practical starting point. For a larger electronic fob, compare the available space in MLK5412A AUTO XXL.

Can I buy a car key safe in Switzerland?
Yes. Both models can be ordered directly from KeySafe Switzerland, with Swiss delivery.
