An RFID system consists of a transponder that contains a code and a reader for reading out this identifier. RFID is also used in banknotes, payment cards and animal collars, among other things.

Question 19

What is jamming?

While the owner wants to lock his car at the push of a button, the thief sends out a jamming signal via a device called a "jammer". This jammer blocks the locking of the doors, the vehicle remains open and accessible to everyone. If no typical locking sound can be heard, it should be locked again by hand.

Question 20

What is a “Keyless Go” scanner?

A “keyless go” scanner, also known as a radio wave extender, consists of two parts, the “car scanner” and the “key scanner”. While the "car scanner" is placed close to the vehicle, the "key scanner" must be near the key. After the signal has been transmitted from the “key scanner” to the “car scanner”, the car can be opened and started. After that, the “Keyless Go” scanner system is no longer required, the engine continues to run even without a key, and the vehicle can be driven away.

Depending on the configuration, seat and mirror settings are also saved.

What's the trick with the suitcase?

Car thieves often hide a keyless go scanner in a briefcase or two. You should be puzzled if two men are with you and your car for a long time with a suitcase or two.

Question 25

What is the "SecuKey" security system?

The "SecuKey" security system consists of a module and 2 high security keys.
