Audi A4 B6 - Remote keyfob wont work !

[Ray Singh]

I have an Audi A4 1.9tdi SE (52 plate)due to a long daily commute.

I went out this morning and the car opened up from the remote as normal. But on returning home the remote wouldnt lock the car. I assumed it was the battery, so i changed this. But still not working.....Both batteries measure just over 3 volts on a meter.

When i bought the car, it only came with one key.

Any ideas please??

Have you re-sync'd the remote? From memory, I think you have to first use the key manually to open the drivers door, then start the ignition, then use the remote to lock the car.

Thanks JonP68 - I will try this tonight when kids have gone to bed......

Funnily enough I had the exact same problem apart from the fact that I didnt actually drive the car after opening it I just left it on the drive open. Couple of days later the snow had cleared so I took it out for a drive came back hit the button and it locked straight away. Couldnt understand it

Be careful Remagel2507.

A couple of weeks ago my wife told me that the key fob wouldnt work. Then i went out to try and it worked again.

Could be yours is on the way out too? I hope not though......
