PVC door lock

[Mojooo]

Hi
We have lost one of our door keys and want to change the barrel

I have read about doing it online but can anyone confirm how to do it and how difficult it might be/cost of a lock?

You can view a couple of pics here:

I am guessing the handle will need to come off?

The other 2 pics which are similar show the bit that comes out to stop the door opening when the door shuts. i guess this bit stays the same and only the barrell changes?

In which case do the 2 screws above/below have to come out to release the barrel?

One the new barrel is in do you just screw it straight in and it will all work?

normally the handles stay in place.
There should be a screw directly inline with your key on side of door, unscrew this and your barrel should slide out, sometimes its easier with key in it to wiggle about.
New barrel just slides in and the screw on the side of the door tightens in to the barrel.
You should be able to pick up a decent barrel for around £10

Thats a euro-cylinder lock. When replacing it, they come in different sizes (lengths/thickness) and some are non-symetrical.

When you buy make sure you get a hardened one/anti-snap and make sure that it does not protrude on the outside. Many can be broken in the middle by applying mole grips and wiggling them from the outside. Makes them popular with a certain class of citizen.

i will prob goto the lock shop with the barrell out and make them give me the exact same one/best one i can afford

just read this - i like the idea of being a bale have a knob inside rather than the key... if we leave out key in then no one can unlock from outside.

bear in mind if you have a knob on the inside it may be easier for thieves to access

hand throo the letter box type thing - or soemthing else?

[Raverbaby]

yeah if thats possible, or if you've any small panes of glass in your door that are easily smashed to get a hand in to turn the knob.

The lock cylinders are very easy to change, just undo the screw at the edge of the door that is just under the lock barrle , put the key in and turn it just a bit and waggle as you slowly turn the key . You will feel when it becomes free and pull it out using the key.
Measure it either side of the 10mm locking part it will be something like 40mm-10mm-30mm.
Put your old lock back in and pop off to the shops with your measurements and get a new lock of the same dimentions.
By the way it is now reccommended to have thumb turns on the inside of your main escape doors so you dont have to look for a key when trying to get out of a blazing house.
I think all UPVC doors are fitted with toughened / laminated double glazed glass so its not so easy to break and put a hand in.

Look out for locks with at least 6 pins, anti-snap to prevent torque attacks, anti-drill pins, and ideally anti-bumping feature, though I'm not sure just how effective the last of these is (YouTube lock bumping :-o )
handlestore.com have some for about £10 or so

Bumping requires a blank key of the lock in question and the high security barrles have registered blanks available only to the lock's registered owner. No blank, no bumping!
