The primary factor Audi A3 keys are challenging to reproduce is the Immobilizer System. Audi has made use of a number of generations of this technology (Immo 3, Immo 4, and the most recent MQB platforms).
The Transponder: When the key is inserted or spotted, the car sends out a signal to the chip. The chip should respond with the correct encrypted code. If the code is missing or incorrect, the engine will turn off after a couple of seconds.Component Protection: In newer A3 models, the key becomes part of a "component defense" ecosystem. This implies the key is digitally wed to the lorry's VIN (Vehicle Identification Number) and can not be easily "single" to be utilized on another lorry.Approximated Costs of Replacement
