Door jamming 'deadlocked' on 406

My 2001 406 estate has just developed a fault with the front passenger's door.

I normally lock, then deadlock, the vehicle with one push of each of the
buttons on my key. When returning I use the same remote to unlock, however the
passenger's door remains deadlocked (or perhaps just locked ?).

If I don't deadlock remotely, simply lock, then it unlocks again fine.

The only way to open the door if stuck 'electronically' deadlocked is to
physically insert my key into its lock.

I'm guessing I've got a duff solenoid ? Any experience out there on how easy
to repair etc ?

TIA

 

Same problem on drivers door of Jun 2001 406 Hdi Rapier Estate .
Solution WD40 in doorlock. Why not do the lot when can in your hand?

Happy 406`ing in 2006 to one and all.

I have had the same problem with the two rear doors on my 406. I have had to
replace the locks each time as once the problem occurs there is no way of
opening the door.
I have broken one of the locks to pieces, electrically they contain two
electric motors and a set of contacts to determine when the door is closed.
The problem is a design fault (The lock is almost entirely made of plastic.)
The lock wears and the fault occurs, it mainly affects the deadlock unlock
operation. The lock being plastic is glued together and cannot be repaired.
My solution is NOT to use the deadlock facility and use a good quality
steering lock much cheaper than the £80+ for the lock + fitting.

Thanks Mike and Wally for your responses.

I took Wally's advice and squirted WD-40 in the affected lock, and that's
restored things, however I take note of Mike's advice and will aim alter my
locking habits accordingly.

Happy New Year

 

Glad to have been of some small assistance. Where possible, I prefer the
KISS approach.( Keep It Simple Stupid). I always lock by using the key
in the lock and ,unlock, by using the button on the key fob. This
ensures that both methods are OK.

All the best for 2006

I am bemused by this thread - my 406 (406SVA98) does not seem to have
deadlocking - we have two keys - one with a button (my wife's) one
without (guess who). As far as I can tell the effect of locking
manually or by the button is exactly the same and has been sufficient
to protect this vehicle for the 6 years we have had it.

An additional level of protection - deadlocking - seems like overkill.
I have another vehicle - a Ford - much more recent - and there were
problems with something called the 'body control module' which gave me
a very bad time (immobilising the vehicle unpredictably) until the
module was replaced. Noone ever managed to diagnose the problem and the
cure was, as I say, quite drastic.

The KISS principle is one we should always bear in mind when
considering electronic anti-theft devices. My Ford experience convinced
me that the people who service these vehicles have little more
understanding of these systems that the owner.

 

Have you tried pressing the button twice when locking the car?

It depends upon the type of area you live in. If cars are regularly
broken into, at least it means that the thief has to get everything out
through a window rather than being able to open the door.

The increasing use of electronics is definitely making cars less
reliable than they used to be.

That definitely appears to be the case. The "master tech" at my local
Pug dealer admitted to me that he ended up getting another 807 alongside
mine to do fault finding - comparing what they both did and assuming
mine was the broken one (as that is a pretty good assumption on my heap
of junk).

Nevertheless I would stick with that dealer - the 807 guinea pig was
probably either his or his boss's. Your 'master tech' demonstrates how
to survive in the digital age.
