Door Lock Barrels
#1
Hi - this is my first post on here...

I've just bought a 2nd hand 2007 Berlingo van, with the 1.6 HDi engine.

It has a few issues which I'm trying to rectify, and rather than it get all confusing, I'm going to ask about each one separately.

So ....

The external key barrels on both the RHS & LHS passenger doors just 'spin' around without operating the door lock.

In fact, you can take a screwdriver and 'spin' the barrels regardless of the key.

I have removed the barrel from the door...

My questions :-

1) Is this normal ?

2) Is the barrel(s) broken ?

3) Do I have the wrong key ? The key I have operates the fuel cap and the ignition correctly.

4) Assuming it's the correct key - can I take the lock apart and repair it, or is it a case of just get new.

5) If I need new - are the ones advertised on the internet where you get a complete set any good, or are they rubbish ?


I hope that's ok to ask in this way. 

Thanks

I've got an older model (2001) and have had the same thing happen.  I suspect the locks just get worn, but perhaps were never precision engineering in the first place (I've been able to operate the lock by sticking the key just part way in - even less than 1cm - and have only part jokingly said that these locks could probably be operated using a fingernail). I guess the fuel filler cap still works fine cos it doesn't get used as much.  The ignition lock seems a more robust construction so probably lasts longer, though eventually even that will wear out.

I never attempted to mend the locks so can't comment on whether it's possible - my door locks became redundant because for security reasons I had mortice locks fitted lower down the door by a van lock specialist.

Something to remember when getting new keys and locks is that the old keys contain a chip that, when they're inserted in the ignition barrel, deactivates the immobiliser.

Thanks for that...

I've had a look at the lock barrel in some light on my bench, and having initially thought it might be possible to get into the lock via the rear of it once you remove the circlip... that doesn't actually help.

It looks like the lock was assembled from the front and then the front must be crimped or swaged on to hold it all together. So I suspect you can't do anything with them without destroying them ...

If anyone knows any different that would be interesting, but I think it's new locks time.

I've moved this thread also to the M59 section and left a re-direct in place for 7 days.

I had a similar experience with my Caddy van (mk2) where the locks had a security paddle designed to break off if the locks were forced, and in winter it decided to use that function on me even with the real key. This was a vehicle with no central locking of course, and an SDi, couldn't pull the quilt off you if it tried, and I ended up having to climb in the back every day to get in but could slam-lock the doors at night when going in the house.

Never tried taking the locks apart on my M59's in the past and generally never tried to even use them, as in the days of remote controls they just get crapped up with dirt and stop working anyway. Especially the rear doors - even on the B9 my key barrel action on all doors are as rough as dogs and it's only 6 years old.
