2010 Audi S5 Remote Flip Key Replacement - Fast, Affordable & Professional
When a 2010 Audi S5 key is done wrong, it does not just partially work. It fails. The engine might crank but the immobilizer kills fuel injection after two seconds. The remote might lock but not unlock. The comfort access might detect the fob one day and ignore it the next. Or the key programs initially but the car rejects it after a drive cycle.
A veterinary technician at the dog grooming shop in San Ysidro had a key made by another locksmith for her S5 that stopped working after about a week. It would start the car fine in the morning, then by evening the push-to-start refused to detect it. She thought the car had an antenna problem.
The previous locksmith had used a generic transponder chip that was close to the Megamos spec but not exact. On Audi's immobilizer system, a close-but-wrong chip can pass initial registration but fail after the car runs its deeper verification over multiple drive cycles. I used my VVDI2 to read the chip in her bad key, confirmed the data was wrong, and programmed a new key with the correct Megamos generation matched to her FCC ID IYZ3314. Her fob also had a low CR2032 battery making the intermittent detection worse.
The replacement has been working since. Her cost was $298. The dealer would have charged $542. The difference between a key that works and one that works for a week is chip accuracy.

“I needed two keys made for my Honda Element. Friendly, fast, fair pricing, and far better than any other locksmith I have used in the area. Best service by far.”
“I lost my Honda Passport key and called EZ Car Keyz. He came out and made a new key in under five minutes. Legendary service.”
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
