The alarms we use now were not precisely like this contraption, though. Instead, it required a three-digit code to be entered before the automobile would start. The horn would automatically activate if someone tried to break into the car. Aftermarket car alarming systems have a separate horn to indicate if there is some situation. Most of the factory-fitted systems use the horn as their primary alarming system. 

Keyless Entry Systems

The key fob of a keyless entry system looks for radio signals sent from the vehicle to function. When you put your hand on the handles, a keyless car will transmit a radio signal. The fob will send its very own message back to the car.

Typically, the signal range is five meters. Suppose the vehicle meets those circumstances; the onboard computer will unlock the doors for you. This is a modern type of security system but not much protective as other security systems. If someone has the key fob, the car doors will also be open for them.

Systems for unlocking boots without a key are also gaining popularity. To automatically open the boot, shake your leg underneath the back bumper of the vehicle.
