Euro cylinder lock issue.

[5oysterman2]

Morning guy's. I have a uPVC multi point door fitted with a Euro cylinder lock. Every now & then when you go to lock it, the key will only quarter turn & stop. The door seems to be locked.

Any idea why it does it & to remedy it. Thanks for any replies.

How long has it been fitted for?

I am not a locksmith (!) but I have found that a combination of uPVC door clearance hole size/location, the handle plate fixing lugs, and the multipoint lock assembly location can all cause difficulties. A smidge out of alignment and the Eurolock can bind in the manner you described.

Temporarily loosening all or some of the fixings (and giving everything a wiggle) can provide a clue that things can work, if only the overall alignment was knob on.

I have previously widened the through holes (very slightly!) when fitting new handles and testing the key will turn as I tighten everything back up again. I am not talking about large adjustment here. The lock points still need to align with the frame.

Don't forget the uPVC is quite soft. Over-tightening into the plastic is a risk for the unwary.

HTH!

I fitted this about 3 month's ago. I'm just a bit slow on getting thing's sorted out nowadays.

Cheers for the reply. Something to look at.

Start simple , give the key hole a squirt of wd40

And give the euro cylinder a loosen , euro cylinders/ oval cylinders don't like being too tight

What make is the euro cylinder and did the old cylinder do it?

just to check, does it do this when the door is open (lock mechanism binding)? Or only when it is closed (latch, bolt or rollers binding)?

Sounds like a common problem just after installation, the door has settled and needs re toeing and healing or if it's just a minute amount can be done with the hinges. As John says does it do this when trying with the door ajar because usually if the key won't fully turn enough it means the handle isn't right up, trying with the door open should prove this theory. Another issue could be that IF it's the key that throws the deadbolt and not the handle it could indicate the door has in fact dropped and the deadbolt isn't lining up with the slot on the striker plate now, again trying this with the door ajar should prove this

It's a Yale(I think) one & the old one didn't do it at all. Will try the wd40 & loosen when I finish work later today. Cheers!!!!

Little heads up:
Don't use WD40. Silicone spray or graphite spray!
Most lock instructions have in the small print any other lube invalidates the guarantee.

WD40 is a de-greaser so it may help immediately but will damage the lock as it strips the grease out. Also it remains tacky so attracts dirt making it worse again

+1 on avoiding WD40 in a lock. It can gum up the workings.

Good point.

I have an unhealthy relationship with wd40......

It's great at removing sticky residue though!

True, Million and one uses but not a true lubricant

Apologies for not replying earlier. It seems to be only when closed. I have sprayed some silicone on it, hope that does it.

it's adjustment then. see crank39 above.
