A3 fob not unlocking

[Zee]

Hi All,

Today my fob both usual & spare have stopped unlocking the doors. I have to use the keyhole to open it and when I turn the ignition it unlocks the rest. However both fobs lock the doors as usual. 

It can't be the battery I've been told. Any advise is appreciated.

Welcome to the forum Zee :)

you'll find the members on here are a friendly and helpful bunch :) 

I had a similar issue with my a6 and found the drivers door locking mechanism to be to blame. Cost me £120 to fix. 

Obviously it's not a central locking issue as the doors unlock when the ignition is turned and locks off the key. 

Hope iv helped :) 

cheers

Hello Zoe,

Re. "It can't be the battery I'm told" , I would be tempted to renew it as an insurance - but not with a £ shop one! In my view, the batteries (inc. spare fob) should be routinely renewed. I'm with Steve on this, and I'm sure you will find that everything is controlled from the driver's door mechanism.

It might be worth injecting some WD40 or similar down the door frame towards the area below the lock barrel ( you sometimes see some sort of nozzle access point below the lock mechanism when the door is open). Possibly won't sort it but worth a try? 

There are varied suggestions for recync- ing key fobs, but I've never had any luck with them, but again you could try. 

Kind regards,

Gareth.
