FAQ - Frequently asked questions


flinkey combines digital and classic locking technology. The key for the vehicle is safely stored in the flinkey Box in the vehicle. All vehicle users who have received an access authorization through the WITTE Digital Portal can see the vehicle in the flinkey app. The user selects the vehicle and sends a digital command for operating the key to the box via an encrypted Bluetooth connection. If the vehicle is locked, it will be unlocked. If it is unlocked, it will be locked.

Installation is really easy and non-invasive: Place the flinkey Box in a convenient location in the vehicle – in the boot or on the center console. The box can be placed vertically or horizontally, just as you like. Installation is not required. In the WITTE Digital Portal, you register the vehicle, the user and possibly the period of use– from your workplace or from a mobile device. And the user is ready to unlock the vehicle via the flinkey app. That's all. No installation, no damage, no key programming, no access to the vehicle CAN bus.

We offer the flinkey app for smartphones with Android (from version 4.4 and higher) or iOS (from version 8 and higher) operating systems.
