The introduction of car chip

 Car key chip types:

There are three kinds of car key programmer chips available: fixed code, rolling code and encrypted code.

Fixed code: the code is fixed and includes a fixed string of numbers and letters. The code will not likely change as soon as the engine starts.

Rolling code: Each key carries a different electronic code. The code are going to be changed when motorist turns the main element to start the automobile. The code-changing program is merely known because of the manufacture which is hard to be cracked by reading chip memory.

Encrypted code: encrypted code is requested for latest chips and chip controllers (which uses two-way encryption technology). encrypted code gives you internal program algorithm, that permits users to decode the encrypted data.

Chip Controller
A chip controller is an electronic anti-theft system that communicates with engine control equipments. It is additionally often linked to car engine. The car engine will become only when chip ID is recognized.
