Audi S3 2010 Key fob not working


Registered User
Hi guys, basically took my car for a valet on saturday, ever since key fob has not been working... Replaced battery in key, read and attempted what must be every method to resync (only have one key)

Manual says to press any button, use key to lock/unlock door then press any button but does nothing all other methods result in same

No luck... Begining to think its related to the valet... Maybe damaged some electronics but i would hope not.

Any ideas?

Mine sometimes does this, but if I unlock the door with the key and then cycle the ignition on and off with it, it resyncs itself
