🔧 PRO TIP
A 2015 A4 owner on a major Audi forum reported a dealer quote of $650 plus tax for a single replacement key, plus about $100 for the tow. We can do the same job on-site for significantly less because we carry the bench tools that talk directly to the BCM2.

2016 Audi A4 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 Chula Vista 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 2016 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 , was programmed through the correct factory data path.

Her spare cost $95. The dealer quoted $200. 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.

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”

Audi A4 Mobile Service FAQ

Real costs, no dealer surprises

Do you use OEM or aftermarket keys on Audi vehicles?
We use OEM spec keys that match the exact FCC ID, chip type, and frequency for your specific Audi model. On newer Audi vehicles with BCM2 and component protection, the system is extremely specific about what it will accept. A tech in an Audi forum explained that aftermarket keys sometimes fail because certain modules need a valid factory crypto signature and aftermarket fobs do not contain it. One owner on an older C6 A6 had no issues with an aftermarket fob, but on 2018 and newer BCM2 cars the risk of component protection failures makes verified keys essential.
How long will the replacement key last?
What if the new key stops working after a few weeks?
