has anyone had trouble with door locks on their van

Same with us, door is locked, insert key and turn, handel pops out but door won't open, turn key again and handel goes in and we repeat till it works which is usually the second time.
Cheers

hi all
some of these have internal plate mechanisns and are held together with a couple of screws that run loose due to corregations /vibrations so i found out
on a van i was reparing cant remember the brand of lock
i also had same problem going around aus in 1980 with the viscount door lock ran loose as well
the results of this are that when you turn the key or knob because the parts are loose you dont get the normal movement while trying to unlock or open the door and so the lock tongue /mechanisn does'nt move the require amount and does'nt release the latches
dismantle the lock
note:
some have security type screws and you might need the the required kit drivers

which is done from the internal side and tighten the loose screws and you should have no more problems a small quirt of lube on the parts will also be benificial
any handy man could do it
just take note of how it comes apart and which way up the bits and pieces go if anything is removed lay it out in sequence as it dismantled warning

do not apply -excessive- tension to the scews as the are only usually going onto alloy parts unless it's a real classy brand of deadlock ???????
cheers

Baz - sounds like you have the Camec 3 point lock. Go to this link. Click on the picture of the lock and get a larger image. Where the LHs and RHS are joined you will see a very dark piece over the lighter piece in the background. If you look closely at the dark piece you will see a little tit poking out of its RH end. This must be pushed back into its housing for the lock to operate. This feature is to stop someone from locking the door with the keys inside.

When the lock is operating properly and the door is closed, the striker plate pushes this tit back into its housing. If the striker plate is set out of kilter then this tit will not go right home. You will then not be able to lock the door with either the key or the inside snib or they will be notchy to operate. You can try adjusting the striker so its lower portion is a little further out. Alternately glue something to the striker where the tit hits it so that packing pushes the tit further home.

For those having difficulty locking or unlocking the door, push the door hard home whilst operating the Key or the inside snib may assist until you get the lock fixed. If the door frame is bowed out so the tit misses the striker you have next to no chance of getting anything in from the outside to push it back. You will have to get inside somehow to do the trick.
