Key Fob A4 B7 does not work after battery replacement

[gio6500]

Hi,

yes you guessed it, its me again.

My spare key i have changed the battery and i can confirm it is a like for like replacement. however the butons on the fob are not working. some users on other forums have said to open the door using the key, put the key in the ignition and then start which should re-program the key back into use.

i have done this but the buttons still do not work.
i have looked at my manual to see if there are two batteries possibly but it only talks about replacing the one.

Anyone help?

In the ignition, ignition on, pres lock/unlock 3 or 4 times then try it.

If that fails it's lost the code and will need re-programming.

I have given that a try but it still doesn't work. Will have to reprogram. Can I do this via a tutorial or do I need to go to a specialist/dealer?

Will need to be someone with a 5051 so probably dealer.
