I'm not sure if I mentioned it here (I know I did on another post) but I took a gamble with my ignition lock as I don't have any keys with the van, so I stripped the door, sliding door and engine lid locks off and ended up with a total of three separate key codes.
Now I know the cab doors are wrong (not 68 handles) so they have been changed in the past, it was more than likely that the sliding door was original and the engine lids also been added at a later date but I ordered two keys from these codes.
Anyway the keys turned up very quickly (which for once was actually annoying as I was working nights
Sorted
Only strange thing was it didn't work in the sliding door (the code I actually ordered the key from) but that problem soon became apparent once I started stripping it.
So today I took a look at the other locks to see about putting them all onto one key, which is a tad frustrating but surprisingly very easy to do.
Yet again like everything else with this van I didn't think it would go this far but looking at the crap in the locks it was (yet again) well worth doing.
Most of the locks are generally in this sort of condition,

Except for that stubborn sliding door lock, which took about an hour to get out of the lock as it was seized solid. To free it I ended up soaking it in boiling water with the hope that all the different metals would free themselves up and it worked a treat.
This is the sliding door lock, in a very sorry state.

Cleaned the external of the barrel and it shows just how stuck the tumblers are in the barrel (with the key removed they should all be sticking out!)

So I pulled all the locks apart and cleaned each tumbler, you can also see a lot of the springs are knack erred but luckily I had a spare lock to steal the springs from.
Stripped

And cleaned,

Reassembled (tumblers are actually free and spring loaded now 8) )

All greased and it's now super smooth back in the handle,

still got the engine lid and tailgate to do (hoping the tailgate is original) but I now have one key that's fits both front cab doors, sliding door and ignition,
Just the big brake hurdle to get over..
