In our app, you can, on your active rental, press the button “open the lock” and then press “open the lock temporarily”.
Remember to enable location services on your phone!
The individual lock is coded to the individual Freetrailer and can only be opened when you have an active rental. It is possible to lock and unlock the lock as many times as you want during your rental period.
The lock can only be opened with Bluetooth. The lock cannot be opened remotely.
These suggestions often solve the problem:
- Make sure your phone is not connected to other Bluetooth devices (e.g., car, headset, etc.)
- If that doesn’t help, enable location services/GPS. It must be on at all times.
- Turn Bluetooth off and on and restart the app.
- If you’re still having issues, restart your phone.
- If it still doesn’t work, you can clear your phone’s cache and restart. iPhone: Settings > Safari > Clear history and website data Android: Settings > apps > Freetrailer > Storage > Clear cache
- If it still doesn’t work, we recommend trying another phone
The light on the lock
With a short press of 1-2 seconds, the lock will light blue and white, meaning everything is okay.
If the lock lights red, it indicates that the battery is low, and you may not always be able to open the lock.
No light on the lock?
1. Press your thumb on the three buttons for about 30 seconds.

2. Turn the lock upside down and find a hard object (e.g., a piece of wood, a rubber hammer, a stone, or the sole of a shoe). Tap the bottom of the lock 3-4 times in the area marked in red until the light works again.
3. Shake the lock firmly.
You can also “jump-start” the lock by holding a V9 battery against the two small buttons next to the round touch button for a few minutes.
