Car key safe Switzerland for vehicle key storage

Keep a car key directly with the vehicle
Mechanical window-mounted car key safes let you leave a vehicle key directly with the car. BELS17A is our proven compact off-the-shelf model. For modern electronic keys and bulky fobs that simply will not fit standard car key safes, we created the MLK5412A AUTO XXL ourselves by adapting the larger Master Lock 5412 and fitting our over-window vehicle mounting bracket.

How it works

Fast installation
Lower the window slightly, hook the finished safe over the glass using its fitted bracket, then close the window again. There is no drilling or permanent modification to the vehicle itself.
Controlled access
The key stays directly with the vehicle. Give the mechanical code to authorised users when they need access, then change it when access requirements change.

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
No batteries, no app and no charging. Access is controlled by a mechanical combination that can be changed when required.
Two genuine solutions for different key sizes
The BELS17A is the straightforward choice for a standard car key. We created the MLK5412A AUTO XXL because many modern electronic fobs, badges and access cards need considerably more internal space than compact vehicle key safes provide.

Overview

A car key safe is a mechanical combination lock box that hooks over a car window. Lower the window slightly, hang the safe over the glass, then close the window again so the unit is held in place. A protective back pad helps reduce the risk of marking the glass.

On this page you can compare two models. BELS17A is the proven standard model for normal car keys and straightforward everyday use. MLK5412A AUTO XXL is the larger Swiss-prepared specialist model for bigger electronic fobs, badges and access cards.

BELS17A or MLK5412A AUTO XXL?

Choose BELS17A if you want a compact, proven and practical solution for standard car keys and normal private use. It is the straightforward off-the-shelf option for people who want secure vehicle key storage without unnecessary complexity.

Choose MLK5412A AUTO XXL if you need more internal space for larger electronic key fobs, access badges or cards, or if the safe will be used in a more demanding shared or professional setting. It is the Swiss-prepared specialist option for cases where a standard-size model may be too small.

Useful across Switzerland

A car key safe is especially useful when carrying the key is awkward, risky or simply inconvenient. It helps keep the key with the vehicle while avoiding obvious hiding places.

  • Outdoor activities: hiking, skiing, cycling, trail running and active day trips.
  • Water-based activities: when carrying the key on you is impractical.
  • Shared access: family members or another trusted person can reach the vehicle when needed.
  • Professional use: useful for shared vehicles, planned access and larger electronic access items.

Simple fitting

  1. Lower the vehicle window slightly.
  2. Hook the window attachment over the glass.
  3. Raise the window again so the safe is held firmly in place.
  4. Store the key, close the cover and set the code.

The result is quick, mechanical and easy to understand. There are no batteries, no app and no charging issues to manage.

Use it well

  • Keep the code private and change it when access needs change.
  • Check internal space if your vehicle key fob is unusually large.
  • Keep the unit discreet and avoid leaving other valuables visible in the car.
  • Close the cover properly in wet or winter conditions.
  • Follow your own local or insurance requirements where relevant.

Main points

  • Mechanical combination access with no batteries required.
  • Window-mounted fitting for vehicle-based key storage.
  • Protective backing to help reduce contact marking on the glass.
  • Two size approaches: compact BELS17A or larger MLK5412A AUTO XXL.

Is installation really that quick?
Yes. The system is designed for fast fitting and removal in normal everyday use.

Which model is better for a normal car key?
In most straightforward cases, BELS17A is the right starting point.

What if my key fob is large?
Choose MLK5412A AUTO XXL when you need more internal room for a larger electronic fob, badge or access card.

Does it need power?
