Remote fob stopped working

[Scott Petrie]

Hi
My 2021 A3 remote fob has stopped working. I checked in the MMI info and it says there is only 1 key programmed to the vehicle. The car has recently been in the garage for some work and a software update but just noticed my other key doesnt work. Is this something I could solve myself or will it have to go back to the dealership?

Stopped working for lock systems or, & the car starting?

Yeh it wont unlock or lock the car

They may have reset the lock systems when they updated, I'd just pop to the dealer as it takes minutes usually.

try this from page 41 of the owners manual

Thats not in my owners manual, and theres nothing at all about if the key stops working. Ive spoke to the dealer and apparently when the car was in they recoded a control unit but didnt do the 2nd key so will need to be done

Have you tried it though - it worked for me.

Ill try it once the rains off! How do I remove the cap on the door handle where the lock is? Ive tried pitting key in the slot underneath but its solid?

Sorry - I have a key hole and that bits not in my manual.
