Changing my door lock tomorrow , any advice ?

[Spartacus]

Got to change my passenger door lock on my 4200 tomorrow , are there any tips before i start ? i already have the door panel off .

it just looks like a pain as the window runners look to be in the way ?

Have a look at this thread Martyn

Runners are not in the way. It's just fiddly.

Check the new push rod holders are the correct diameter. I had to swap mine from the old lock as there was no way it was going to fit.

Best of luck

Cut 3 of your fingers off on your right hand and you should be able to reach it no bother!

And here is a guide to removing the door card:

Go easy removing the alloy strip that covers the screws, they can snap and also its easy to damage the leather levering it off. Put a feeler gauge under the lever so you dont mark the leather door card.

changed mine last year, there isn't much room but is quite easy.

I thought the worst part was removing the door card but you've done this already!

Take some photos please...I have a hunch mine is not registered as closed and thats why I am having window drop issues...there is a micro switch in there...some where!

i take it that you un bolt it from the outside of the door end , remove the control rods and then refit the control rods to the new lock and re bolt to the door ?

BWHAHAHAHAHAHAHHAHA

No

The rods don't fit like that, although you *might* be able to disconnect at the remote end, I confess I didn't try that.

I loosened the lock, unclipped the rods, then took the lock out.

To put it back I put one bolt in loose to support the lock, the reattached the rods (dental mirrors and rat's teeth forceps are quite useful)

There may be a better way

seems i may have the lock/unlock issue, its happened just a few times but want to get it fixed before it gets worse.

passenage side is fine and works great, no battery drain, no water in foot well (it never really sees rain).

I can't seem to work out how to remove the lock / unclick the rods without breaking the clips.?

 

[CatmanV2]

With difficulty if memory serves. I probably used the rat's teeth or fine pliers.

It has been a while but you can move the window to a position to give less obstruction with the lift mechanism.

Also I remember unbolting it from the door first to move it a bit, then giving better access to the rods and connector etc

 

[EnzoMC]

thank you both for response guys... lock and door handle out only one clip broke but now see how its done so will take some pics and post up

 

[Lozzer]

Hardest part when I did it was re-connecting the rod for the exterior door handle, it was tight as f*, luckily there is a hole in the door panel you can put a screwdriver/rod through to push it home.

 

[BennyD]

Yes, mortice locks are better than Yale.

 

[EnzoMC]

whilst I'm waiting on parts to arrive and with the door panel off - I'm going to clean the window rails and re-grease
any suggestion on which grease to use ? a few roogle search suggest hi-temp silicone or white lithium ?

 

[conaero]

Yes, Lithium on the metal scissor action, 3in1 silicone spray on the rubbers and channel guides. The silicone makes a massive difference.

thanks Matt

below is a ruff outline for replacing door lock on GS (should be similar for 4200s / 3200s)

I didn't switch the battery off but its always recommended when working on electrical items.
normal disclaimer - both SM and I are not responsible for any damage or issues caused by using this information below.


1 - with windows full up, remove door card (see other thread on this).

2 - peel back foam cover being careful not to rip - this is held on with soft sealant paste.

3 - remove connectors(5) from bottom of lock


(numbered in order or install)




4 - with lever tool, POP out bar(4) from barrel lock - this is stiff and may take some pressure to remove




5 - with lever tool or screwdriver push plastic clip up on rod(3), this should now pop out







6 - remove lock screws on door



7 - easy part with the lock now free, rod(2) should now just pull out

8 - with rod/wire(1) push this down through the gap, this should now be free to pop out




9 - the lock should now be free to remove behind the windows rail.



10 - order replacement lock - right(67294800) left (67294900)
in case you snap the barrel lock clip, its been replaced by 3 parts (1x 38400390 and 2x 53451352)





install in reverse and test after connecting the power(5)

plus items to finish off
1 - I used some loctite 248 on the lock screws

optional - whilst doorcard is off I also cleaned and re-greased the window rails/gear and lubricated the clips for rod(1) and rod(3)

2 - clean off old paste then with small line of sealant paste reapply foam cover


job done
