Whether your key was misplaced, damaged or stolen – only an authorized Audi dealer is able to offer a replacement. Since all Audi key programming is stored in a secure database, a permanent record is available when a replacement key needs to be coded.
The Immobilizer – The New World of Anti-theft Technology
All Audi vehicles are now equipped with a state of the art electronic “immobilizer” anti-theft system. The critical component in this system is a sophisticated electronic anti-theft device – the “immobilizer.” The immobilizer activates when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The immobilizer in the vehicle interacts with a transmitter and receiver unit (transponder) in the ignition key. Whenever an attempt is made to start the engine, the immobilizer transmits a new code to the car’s electronics. The immobilizer keeps the ignition, fuel, and steering systems locked unless a key with the proper code is used to start the vehicle.
The Smart Key – Yours and Yours Alone
Even an exact physical duplicate of a key cannot start the vehicle unless the key’s transponder and the vehicle’s immobilizer have been coded to each other. Securely encrypted and constantly changing electronic codes match your specific key with the onboard computer on your vehicle – and your vehicle alone.
No security system can provide 100% protection against theft, and thieves may be able to overcome the electronic immobilizerElectronic ImmobilizerThe immobilizer is an electronic anti-theft device.Electronic Immobilizer . However, objective data has demonstrated a dramatic reduction in theft rates in vehicles equipped with immobilizer and “smart key” technology. For these systems to be effective, the codes that are unique to a particular key and a particular vehicle cannot be allowed to fall into unauthorized hands. At the same time, vehicle owners who have lost or misplaced their sets of keys need to be able to obtain replacements in the most convenient manner possible, while preserving the security of key coding information.
