Shows: Why It’s Sophisticated
Audi uses a system called the “Immobilizer.” In modern-day Audis (Immobilizer Generation 4, 5, or 5+), the car’s computer and the key take part in a “challenge-response” handshake.

If the action is inaccurate, the engine will shut off after one or two seconds.

Programming an extra key involves linking the car to a secure server-- often connected straight to Audi’s headquarters-- to authorize the new key. This is why DIY programming for newer Audi designs is essentially impossible without professional-grade diagnostic tools.
