• Physical Damage: Cracked cases, damaged flip systems, or buttons that no longer register a press.
• Water Damage: Dropping a clever type in a pool or laundry can fry the internal circuitry.
• Malfunctioning Immobilizer Chip: In some cases, the key might unlock the doors but fail to start the engine since the transponder chip has actually been deprogrammed or harmed.

3. Programming the Transponder

This is the most technical phase. A diagnostic tool is connected to the car's OBD-II port. For newer Audi A4s, the locksmith or dealer need to link to Audi's "FAZIT" database in Germany to license the brand-new key and "present" it to the car's immobilizer system.
