🔧 PRO TIP
Your B6 or B7 A4 uses an older Megamos 48 transponder in an HU66 flip key. We can pull the security PIN directly from your instrument cluster and program a new chip on the spot, no dealer PIN lookup needed.

2003 Audi A4 Remote flip key Replacement - Fast, Affordable & Professional

BSIS license LCO#6792 means I passed California's background check, maintain active liability insurance, and operate a registered locksmith company. NASTF certification means I have access to the National Automotive Service Task Force security database, which provides factory key codes and immobilizer data that unlicensed operators cannot access. Google Guaranteed means Google verified my license and insurance independently, and if the job goes wrong, Google backs it with their guarantee.

An overnight hospitalist at the parking structure of the hospital in the San Marcos Pass neighborhood in Santa Barbara late at night told me she had checked my license number before calling. She works alone in a dark parking garage after midnight and was not about to let an unverified stranger near her car. She needed a spare for her 2003 Audi A4 and wanted to see credentials before anything started.

NASTF access matters on Audi specifically because it gives me factory security data for the immobilizer system. When I program a key using my ACDP or any of my tools, the NASTF database provides original PIN codes and security credentials that verify my access is authorized. Unlicensed techs without NASTF use workarounds that can leave fault codes or incomplete registrations. Her fob, FCC ID MYT8Z0837231, was programmed through the correct factory data path.

Her spare cost 264. The dealer quoted 492. You can look up LCO#6792 on the BSIS website right now. My reviews, my YouTube channel, and my Google Guaranteed badge are all public.

Audi A4 Emergency Key Replacement FAQ

What to expect when we arrive

I lost all my Audi keys. Can you still make a new one?
Yes. All-keys-lost is one of the most complex calls we get on Audi vehicles, and we handle it regularly. On BCM2 equipped models like many A4, A5, A6, Q5, and Q7 models, we access the immobilizer module, extract the security data, generate new keys from that data, and program them to your car so the lost ones no longer work. The system wipes all previous keys and only registers the new ones you authorize. Audi dealers will tell you to tow the car in and can quote $800 or more for a single key. We come to you and handle the entire job on site.
Do I need to tow my car to the dealer if I have no keys?
