My 2002 td5 key fob refuses to unlock the car every now and again.
The only way to get it to work is by restting the code by useing the key in
the lock method as per handbook instruction..
This seems to work so far . I am afraid it will let me down all together one
day.
Useing the key to open the door just sets of the alarm.

Any advice please.

Had a similar problem and when we opened up the fob and examined it more
closely there was a dry joint - in fact no solder at all.

It may be more complicated but is it better?

Thanks for your quick response Hugh.
I have two remotes both with new batteries and the problem is the same for
both
so I think it is with the imobiliser itself.

Or local RF interference on/near the keyfob frequency.

Look for wireless burgler alarms, video senders and other such
dodgy gadgetry near by.

Has it always been bad, or has it just sudenly gone bad?

Look for some gadget you bought at abou the same time, or did any
of your neighbors have anything gadgetry delivered at that time...

Dragon had a "N" reg Metro

That had the BL Fob

The car park she used for work was just across the road from the local nick

She had endless problems it wasn't until the RAC told her to park some where else
her intermittent problems went away

I've got some kit at home that wont work anywhere near the Disco

Other things can cause it as well are remote weather stations , remote central
heating oil sensors

The list is endless

The reason being, it all operates on a common licence free frequency.
No garrantee that there will be silence for you, but many gadget
makers/programmers "assume" (wrongly) that they will have the only
access, so the kit they make can't handle other signals they know
nothing about. Some fail quiet, some fail rather noisely, some just
lockup and go dumb.

As you say, the list is endless.

Back in the '80's it wasn't the licence free frequency that was the cause of the
problems

It was High Power UHF transmitters ( 10 watts + ) such as the police UHF base
station for their personal radios that caused most of the problems

The addition of some more components to the alarm system would have resolved these
problems but the manufactures were penny pinching to maximise profits

Now a days the EU have allowed the use of UHF for other licence free devices which
the Ministry of Defence have primary use and the do run high power

There are other users who have secondry use of these frequencies and can run up to
100 watts

If you have someone on your doorstep and you've got problems
