lex[0]='Transponder key – The biggest change to the Automotive Industry in recent times has been the introduction of the built in immobilize system on all cars manufactured since 1995 (late 9-4 in some cases). This involves placing a microchip in the head the key, which is a miniature transmitter and receiver. There is an engine management system in the engine compartment that can recognize the signals transmitted from the key. If the correct signals are not detected the engine will not start.';
lex[1]='Transponder – An electronic chip with a permanent memory which contains an ELECTRONIC CODE. The transponder has an antenna with which it can interface with an external electronic control device. Through the antenna, the device emits a fixed frequency signal; the transponder receives the signal and then transmits its electronic code, by means of special frequency modulations, to the control device, which is able to process the code. The transponder has no external input of power supply (passive system); it receives the energy necessary to work from the signal emitted by the external control device (inductive coupling between the control device antenna and that of the transponder).';
lex[2]='Normal transponders – Keys with normal transponders fitted can be copied by use of RW 2.';
lex[3]='Crypto electronic code – The new transponder and vehicle computer memory are structured to be totally protected in the Radio Frequency communication The code on the computer chip is protected and therefore cannot be copied using a reading / writing machine.';
lex[4]='Changed electronic code («rolling code») – Each keys has a variable electronic code. However, the codes are changed every time the key is used to start the car engine. The procedure by which the code is changed is known only to the manufacturer of the immobilizer and therefore cannot be copied by reading/writing machine.';
lex[5]='Immobilizer – An electronic antitheft alarm which interfaces with the engine control device, and often also with the starter, to allow the engine to be started when the electronic code on the transponder is recognized.';
lex[6]='Fixed electronic code – Each keys has a different electronic code. The codes are permanent (they are not rewritten when the engine is started).';
