About Your 2026 Audi A4
Audi is part of the Volkswagen Group and shares the MQB-platform immobilizer (IMMO5) with VW, Skoda, and SEAT. The KESSY proximity smart key has been on Audi since 2006 and is now standard across most trims. Audi's modern key system is one of the most secure mainstream platforms in the industry — programming requires advanced equipment but we support the full lineup on-site. The most useful thing to know about Audi keys: pre-2006 Audis use IMMO3 or IMMO4, which are well aftermarket-supported and cheap to program; 2006–2014 Audis use IMMO5, which is moderately complex; and 2015+ Audis use the MQB-Evo platform, which is the trickiest VW Group programming we do.
A4 B9 (2017+) uses the MQB-Evo platform with KESSY standard. The S4 and RS4 share the same fob as the base A4.
2015-and-newer Audis (B9 A4, C8 A6, D5 A8, Q5 II, Q7 II, Q8, e-tron) use the MQB or MQB-Evo platform with the latest IMMO5 revision. We support the full lineup on-site.
Sedans are the bulk of our daily key work — they live in the driveway, get used every day, and tend to need spare keys before SUVs and trucks because they're stolen more often when an extra key is missing.
Immobilizer (Audi MLB Evo): Audi shares the VW Group MQB platform. Programming time and blank cost are nearly identical to the equivalent Volkswagen.
