Retrofit smart lock that mounts over a European cylinder and key, adds phone control with auto-lock, sharing, optional Bridge for remote access and logs, requires an emergency-function cylinder, and should use Tedee rechargeable batteries for sufficient current.

The Tedee GO smart lock offers keyless entry with a simple installation that fits over existing door hardware, and it is compatible with Matter, allowing it to work with a wide range of smart home devices and ecosystems.
