Affraid of break-in in your van, truck, trailer or container? You might allready have tried it. Do you remember the ekstra locks EVERY time? And what about the ekstra keys? Don't worry. Herkules is a safe and keyless system. It locks automatic when you lock the car as normal using the central locking system. Only difference is the massive steelbars that locks the doors form the inside. You deside if you want the locks to work automatic or manually. Using a key, phone or keytag to operate the system. When you want to unlock the car, you have to turn on the ignition before the steelbars unlock. That is to avoid sniffing af the key signal. Of course we have a bypass, so when you have to acces the back of the van many times, you simply pause the Herkules system. Next time you start the car, Herkules will automatic be active again.
