Chip car key role and classification

The role of car keys chip

When the car key in the ignition switch is turned on, the car's engine control unit (ECU) will send a coded signal to the encrypted electronic car key inside the chip, and only when the car ECU unit can read the feedback received proper security encoded signal is allowed to start the vehicle. Therefore, even a simple car car keys, no buttons, it can also through internal chip encoding can be turned on and open the anti-theft system of the vehicle. Car keys with a chip, you need to use a special dedicated equipment to be able to match the original programming.

Car key chips (plastic type)

Used in the automobile sector, the chip is called magnetically coupled transponder system. Magnetically coupled transponder system is essentially a passive state. The chip itself does not require a constant power supply, so that no time is energized. Simply by electromagnetic waves within the range of 125 kHz frequency. Chip in an electromagnetic wave will produce their own original set good signal coding, generally 1 cm to 15 cm range. Since this is a radio frequency, which can penetrate the material, the chip does not need to expose the appearance, shape can be made of plastic or rubber, a key head.

In the key identification process works most car alarm system chip is substantially similar. When a chip car key is inserted into the ignition lock, turn to "on" or "run" position, the ignition lock is installed around the induction coil, it will send an electromagnetic wave. Winding key chip radiation, electromagnetic waves generated electricity electronic chip emits a coded signal. The signal is usually a sequence of alphanumeric characters, which is considered the identification code. In the read signal induction coil, and sends it to a computer in ECU identification signal. If the signal is acknowledged as having been in the ECU signals the computer memory, the computer accepts were ECU, ECU controls other electronic components of the vehicle is configured to allow execution state, this time the engine of the vehicle starts to run free.

Car keys chip classification

Chip fixed code and rolling code encryption type.
Fixed: Code is fixed, by the numbers and letters (when the engine is started, the data do not change).

Rolling code: each key has a different electronic code, but every time you use the key to start the engine of the vehicle, the code will be changed. For example: chip encoding been completely copied, the controller system, it is difficult to break through the copy-chip memory, because every time you start the engine when the chips are dynamic password.

Bidirectional dynamic password: the latest chip and chip controller (two-way data encryption) cryptographic code. It is equipped with an internal program algorithm for decrypting each encrypted information.

Here are the common types of chips:

93-- Philips chip (Daewoo Motor)
4C - Texas chip (fixed code)
4D - Texas encryption chip
8C - Big Mac encryption chip
8D - Saab chip (instead of copy)
4D chip:
60-- Texas encryption chip (Universal)

63 - Texas encryption chip (Ford)
64-- Texas chip (if Chrysler Jeep 2000 mine)
65 - Texas encryption chip (for Suzuki)
66-- Texas chip (for Suzuki Motor 2)
67 - Texas encryption chip (TOYOTA / LEXUS)
68 - Texas chip (for Toyota / LEXUS 2's)
XX - Texas encryption chip (new wide type)
