Might be the receiver part that gets the signal from the fob playing up?

Which battery fob or van ?
Check the voltage of the front battery under seat
Do you also have any running or dash problems ?

[leetheedge]

thanks for the reply.no problems with anything else regarding the front battery..ive also looked at the key fob antenna behind the interior light,all seems ok.

Mk6 remote programming only needs keyturning etc, it's almost a clockwork affair

Mk7 requires diagnostic equipment and codes

Also I find that led bulbs can interfere with the signal.

With my Cree marker lights on the fob has to be with in a couple of metres to work, but with them off, the remote works like 1/4 mile away
