The Audi A4 has steadily evolved from a bold newcomer into a refined benchmark of the compact executive sedan class, with each generation introducing new innovations in design, engineering, and interior tech. As these vehicles advanced, so too did their security systems - making expert locksmith service essential for owners across all model years. Whether you drive a first-gen B5 from 1994 or a 2020s-era A4 8W with Virtual Cockpit and digital keys, SherlockLock is Boston’s go-to Audi locksmith. We specialize in key programming, ignition repair, advanced fob replacement, and emergency lockouts.
The original 1994 Audi A4 debuted on the PL45 (B5) platform, carrying over the brand’s signature longitudinal engine layout and available quattro all-wheel-drive. That setup added both handling stability and complexity to the ignition and key systems. These early models introduced transponder chip keys - cutting-edge at the time - and SherlockLock can cut, clone, and program these older Audi keys with ease, even when no spare is available.
With the release of the B7 and B8 generations, Audi enhanced both performance and security. Although the B7 was technically a major facelift, it introduced a redesigned grille and new electronics. By 2007, the B8 model moved to a platform that shifted the engine placement for better weight balance and introduced more robust immobilizer technology. If you’ve lost your key or are experiencing ignition switch failures, SherlockLock offers non-destructive solutions for all post-2005 A4 models, including ECU-linked key programming.
The 2015–2020 Audi A4 (8W) brought luxury-level features to the compact sedan class, from standard xenon or LED lighting to Audi Virtual Cockpit and sophisticated digital infotainment interfaces. By the 2020 refresh, A4 models came equipped with a touchscreen MMI system, acoustic feedback, and optional head-up display - all integrated into Audi’s high-security digital key infrastructure. SherlockLock is fully equipped with Audi-specific diagnostic tools and programming software to replace lost smart keys, reset modules, or handle digital immobilizer faults. Unlike generic locksmiths, we service even the latest A4 systems without requiring a trip to the dealership.
No matter your A4’s generation - B5, B7, B8, or the latest 8W - SherlockLock’s certified locksmiths can handle your key replacement, keyless entry repairs, ignition cylinder issues, and onboard diagnostics. We’re local to Boston, mobile, and available 24/7, so you don’t need to tow your vehicle or wait days for a dealership appointment.
