Key fobs randomly loosing synch.

Morning all,
Have had a good search of the forums but couldn't find the answer.

My keyfobs randomly loose synch and I get the "engine immobilised" message. The car will start after pressing the remote buttons. There is no pattern to it. Drove to work this morning called into Tescos on the way (as I usually do) and the car will not lock on the remote.
Do my shopping jump in get the immobilised message press the remote a few times and it starts. Off to work and when get there locks as normal.

This has happened a few times over the last couple of months with no pattern.

I've swapped RF receivers (I have a spare -not the type 3) and unplugged the aerial to improve selectivity and it still randomly happens with both keyfobs.

Have had the car for 7 years and this ongoing issue is the only real problem-so may have been lucky.

Would the BeCM Sync-Mate get me out of a sticky situation here?

Will only be keeping the car until summer and will be on the lookout for a L322 Supercharged (must be mad!).

Any help appreciated and if it points to the later RF - where can I buy one from as I cannot seem to find any.

Regards

Steve

Thanks Mozz,
You helped me last year. I live near Caerphilly.
The Tesco is quite a large one-but again the occurence is quite random-it has done it once at Tescos and twice where I work (a school). It also did it the other week at home in the garage-although it might have been the fact that I had it unlocked for a week with my battery conditioner connected.
It starts when I press the remote with the key engaged. It never fails to open by remote but when it refuses to lock with the remote I know there will be trouble.

Next time it happens I'll lock it using the key and see what happens.

I'm still sure there must be problems with the BeCM.

Cheers

hi steve , yes I remember , unfortunately the answers still the same my friend you need the mk3 r.f. receiver , theres nothing wrong with your fobs , locks or becm ,,the part no is ywy500170 if you had bought one when I told you it would have cost approx. 100-150 now
you will be lucky if you can get one for less than £250-300 that is if you CAN find one ,sorry but I did warn you !!!!!!!! TESCOS ARE THE WORST CULPRIT ,IF YOUR DRIVING A P38 STAY OFF THEIR CARPARKS !!!!! UNLESS YOU ARE CONFIDENT YOU HAVE THE MK3 FITTED ,,, very easy to check out if its got the blue sticker on hard luck
