🔧 PRO TIP
The 2003 Audi A6 uses a remote flip key with a transponder chip built into the head. The fob and the immobilizer both have to be dealt with separately. The blade gets cut to the car, but the chip also has to be enrolled to the immobilizer before the engine will run. A lot of people buy a replacement fob online thinking they can just get it cut and go. That only gets you into the car. The engine won't start until the transponder side is programmed with the right tools. Also worth knowing: the battery in this fob is a CR2032, and a weak one can cause the remote functions to drop out at short range before it fully dies. If your locks are acting up but the key still starts the car, swap the battery first before assuming the fob is bad.

2003 Audi A6 Remote Flip Key Replacement - Fast, Affordable & Professional

She was at the outdoor shops in RB Town Center in Rancho Bernardo when someone grabbed her bag off the stroller handle. Car keys, wallet, phone, all of it gone at once. She borrowed a phone from a store employee and called her husband first, then the police, then me.

Her 2003 Audi A6 was sitting at home in the garage and she had no way to get to it, let alone into it. Her husband called the dealer while she waited. They said the car would need to be towed in, they would have to order the key, and it would be three to five business days. They also recommended wiping the immobilizer memory since the stolen key could still start the car. The combined estimate was well over seven hundred dollars, and that was before towing.

I got there that evening. All-keys-lost on this generation A6 is a different job than adding a spare. When you have a working key, adding a second one is a registration job. The car already trusts something, and you just introduce a new key to the existing memory. All-keys-lost means wiping that memory completely so the stolen key is dead, then rebuilding from scratch. I cleared the key data from the immobilizer, enrolled two new fobs, programmed the remote functions, decoded the lock cylinder, and cut both blades on site.

Both keys were working before the police officer finished taking her report. She drove home that night with her baby in the back seat. The stolen key does nothing to that car now.

The dealer estimate was a reference point, not a competition. She saved a good chunk and didn't wait a week. That part almost felt beside the point given everything else she had been through that evening.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Audi A6 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace a key for a 2003 Audi A6?
Call a mobile locksmith before you call the dealer. On a 2003 A6, the dealer route usually means ordering the key, waiting several days, and paying for programming on top of the part. If the car needs to be towed, that adds more. The smarter move is to get the key made on site. A well-equipped mobile locksmith can decode your lock, cut the blade, and program the transponder and remote functions in one visit. No tow, no waiting on parts from a warehouse, no trip across town. Call us for pricing. It will be a fraction of what the dealer route costs, and the work happens wherever your car is parked.
How much more does all-keys-lost cost compared to just adding a spare?
Do aftermarket fobs work on a 2003 Audi A6, or do I need OEM?
My 2003 A6 key starts the car fine but the remote buttons stopped working. What is going on?
Can I program a second key to my 2003 A6 myself at home, or do I need a tech?
