KeyFob Classic EM4200
Robust, handy, safe—our key fob, with fixed programmed EM4200 transponder. Made of high-quality, fiberglass reinforced plastic, it is absolutely break- and kink-resistant. And thanks to the ultrasonic welding of the cover (pressure window) with the key ring, it is absolutely watertight and cannot be opened by force.


Identification media such as key transponders are handled several times a day. They are used both indoors and outdoors—so good quality is essential. That's why the KeyFob Classic EM4200 is made of high-quality, fiberglass-reinforced plastic. Ultrasonic welding of the cover (pressure window) to the key fob ensures absolute watertightness and makes it impossible to open the key fob. Thus, tampering is impossible.
