C5 Fob battery change funny

[DuggleBB]

I've just changed the battery in my keyfob for the second time.
The first time no problem, but this time, the initialisation has gone OK, however the touch lock/unlock feature in the door has stopped working.
I can lock the car with the keyfob, and unlock it with the keyfob.
The car starts & stops OK, but if I get out & touch the two lines on the Handle...nothing.
If I lock the car then hold the handle it doesn't unlock the door/car
Really weird
Is there something in the system settings I've missed, I'm sure on the previous battery change apart from the initialisation there were no problems

Are you sure you haven't disabled the Hands-Free option inadvertently?

Have a look at martyness's post - I think you may have disabled it accidently. Instructions are there to re-enable too:

It seems the system went into sulk mode after the battery change.
Next day, back s usual.
Still ignores the odd touch unlock but now about the same as before the battery change,
Thanks for idea anyway
