Transponder Chips and Immobilizers

When the key is placed or identified, the car's Immobilizer Control Unit sends out a signal to the chip. The chip needs to respond with a special, encrypted code. If the code is inaccurate or missing, the fuel system is handicapped, avoiding the car from being "hotwired."
Rolling Code Encryption
To avoid "relay attacks" where burglars intercept the signal from a remote, Audi utilizes rolling code technology. Every time a button is pushed, the key and the car sync to a brand-new audi key, special encrypted code. This makes sure that a recorded signal spoils the minute it is used.
Memory Storage

If a key gets wet, the battery should be eliminated instantly and the internals dried with silica gel.Protective Covers: Silicone or leather covers can prevent the plastic real estate from cracking if dropped-- a common cause of internal antenna failure.Signal Protection: For owners of vehicles with keyless entry, keeping the type in a Faraday pouch in the house can prevent "relay theft" by obstructing the key's signal from being increased by thieves outside your house.Frequently Asked Questions (FAQ)Can I set a second-hand Audi key myself?
