Key keeps sticking in the lock, replaced the barrel but it happened again, think it must be the door mechanism.

Do you mean when trying to turn .. or when inserting/removing  

[Auto Addict]

It turns so far, unlocks the door, but the key then sticks and won't move either way, can't get the key out and the door won't lock.

It happened with the old barrel, but has now started happening with the new barrel, which makes me think it's not engaging the door mechanism properly.

Sounds like wear in the main lock, it looks like a standard euro mortice but best to take it out and go to a locksmiths or builders merchant to match it up.

Does it operate any other bolts at top and bottom?

[Entwood]

On ours, to engage the locks you have to lift the handle, which shoots the bars out, before turning the key to lock.

I have found that when trying to unlock, if the handle is not "central" some interference takes place which makes things "tight".

Remedy was a good squirt of Ambersil 40+ in all the bolt apertures and the lock mechanism... seems to allow the springs to centralise everything properly and remove any restriction.

Don't know if that helps at all ..

[Auto Addict]

Yes, it's standard lift the handle to engage the bolts and lock.

I think what ever the barrel lock engages into, is worn, which if causing it to only half disengage.

My patio door went similar. Blast of WD40 into keyslot to drive out moisture, then after a few hours, a couple of drops of 3in1 down a pin into the slot.  Tend to have to do this every 3 years or so.

Not sure if yours is same issue, or if that helps

[Auto Addict]

I think it might be the springs on that operate the handle, as the handle is feeling slightly sloppy.

Mine did the same, the mechanism was slightly out of alignment ..... bent!  A bit fiddly sorting it, but it's now been ok for a couple of years. I had to drill the old lock out though cos when it failed, it failed locked and was a bugger to open the door to sort it. A new mechanism would be around £80/£90 .... or so the lock shop told me.

i think the whole mechanism is about 80 quid, piece of pi$$ to change, done loads of them

[Kevin Wood]

Mine has done this too. I'd forgotten to put it in "Park".

ours has hook shaped hammers that engage the door frame when you lift the handel, the door was never hung at the correct hight for them to drop fully and the frame holes where in the way, meaning the handel could not lift fully, in turn this stopped the key turning as the handle would not lift fully.

The clue was the mechanism worked perfectly with the door open, shut the door and the handel wouldnt travel the same and the key wouldnt turn.

I knocked the pins out of the hinges, raised the door 2mill by re arranging the nylon bushes, pins back in, now works beutifully.

Ift it works door open then its fouling the frame. If its the same door open or shut then its the door mechanism.

But i notice yours is differant design, might help maybe?

Thanks for all your replies, will try stripping it down.
