2019 Audi a6 c8 central locking fault

[Victoria sherry]

Anyone any ideas central locking has stopped on the key no problem inside 

[Steve Q]

Have you tried changing the key fob battery? 

[Victoria sherry]

No didn’t think it was that as the spare key doing the same the same keys no problem to start the car but just no lock/ unlock

The price of a new fob battery will not break the bank, and would eliminate the obvious and most likely fault.

[jammy]

New battery won’t harm for about a quid.

I would also try pairing the remote with the car again.

[Victoria sherry]

Will try battery just strange how it stopped on both remotes but they will start the car 

 

how do I pair it again 

[jammy]

Put the key fob on the sync point under the central arm rest and start the car. Keep the other key away from the car so it doesn’t interfere.
