Purpose and function of the remote key

The presented "fish" type key has been designed as a remote control component for locks and security systems in selected Mercedes C, E, and S-Class models. The remote's design allows for comfortable carrying in a pocket or bag, and the shape of the housing enables intuitive button feel without the need to look at the key. This makes vehicle operation quick and comfortable, both in daily city driving and on the road.

Construction and button ergonomics

The button layout on the key has been developed to minimize the risk of accidental pressing and to ensure a clear division of functions. The housing has compact dimensions, which promotes a comfortable grip and stable handling. The "fish" shape used is characteristic of many Mercedes models and harmonizes well with the interior aesthetics and the ignition or starter slot, depending on the vehicle version.
