broken lock in a UPVC door

emma.cook3

My lock has stopped working. keys are only working sporadically . My door is UPVC. Do I need a new door or can I just get the lock? I really cant afford a door but cant use the back one regularly as it is inconvenient. (site on steep hill)

is it a multi point lock, ie: do you lift your handle up and turn the key to lock?
Anyway no you won't need a new door, if it's purely a problem with turning the key and it's a euro cylinder, you just need to replace the cylinder, there are plenty of videos online on how to do this and it's an easy enough diy job. You need to take the cylinder out first to take measurements of it so the new cylinder fits properly, generally it's only one screw, 2min job.
Basic cylinder will be around £10-20 or you could upgrade it to a high security avocet abs cylinder for around £40.

Fantastic, thanks. Will have a look.

try spraying some wd40 first before you replace the cylinder, if there is some water/rust inside this can often sort it out, you should be able to pick up a small bottle in the usual pound shops.

Hi,

and here's a wee video, let you see how easy it is.

If you're going to try lubricating the lock, which may well work although I'd suspect it only to be temporary since it's at the stage it is.
I wouldn't use WD40, use either graphite spray or a dry silicone spray, problem with wd over time is that it stays wet and therefore any little bits of grit that may come off your key or in the air ( unlikely in this country tbf) will stick in the lock and seize it up again.
And I realise that WD40 openly advertise on the can the use of it on locks but ask any locksmith or lock manufacturers and they'll advise against it.
