Spark symbolises a spark of innovation, an igniting idea - and that is exactly what this world first is all about: The Spark key is the first battery-free eCLIQ key that generates its own energy.

The energy required for the locking function and for checking access authorizations is generated by a generator in the key during insertion into the cylinder.

Data is transferred between the eCLIQ locking cylinder and Spark with the usual high level of protection against manipulation and intelligent attacks that has always characterized the CLIQ® family locking system.
