V35 / X139 (also known as Ilco V35, X139, V35-P plastic head variant, JMA AU-AH, Taylor X139, AU8 in some references) is a common non-transponder mechanical key blank used on various Audi, Volkswagen, and some Porsche models from the 1980s and early 1990s.
This is a double-sided (same cuts on both sides), typically 8-cut or similar profile key blank, metal-headed (nickel-plated brass) or plastic-headed in variants. It's pure mechanical—no chip/transponder (pre-immobilizer era for these vehicles).
Primary Compatible Vehicles
Primarily fits Audi models from the mid-1980s to mid-1990s, with cross-compatibility on select VW and Porsche models using the AH code series (AH1–AH9282 or similar).
Audi (most consistent and primary application):
Audi 4000 (1985–1987) — All locks (ignition, doors, trunk/glovebox).
Audi 100 / 200 (1989–1994) — All locks.
Audi 80 / 90 (1988–1995) — Sedan and other variants.
Audi Coupe / Quattro models from that era (e.g., 80/90-based).
Some references include 1985–1988 Audi Sedan/Wagon, and overlaps with 1995 models like early TT (less common).
Volkswagen (select models, often shared platform/locks with Audi):
Volkswagen Eurovan (1993–1998, some references).
Volkswagen Golf (1988–1999, select trims/years).
Volkswagen models from 1988–1989 (specific listings).
Note: VW often uses this interchangeably for certain 1980s–1990s models sharing the profile.
Porsche (limited/older models):
Porsche 911 (1983–1991, some references).
Porsche 944 (1983–1991).
