Replacing external door lock

[rutar]

Hello and thanks in adavance for any help on this.

I'm trying to replace an external door lock but can't seem to find an exact replacement.
Maybe I'm missing something or looking at the wrong specs?

I'm attaching photos:
1) lock itself
2) my drawing of the specs

Many thanks

Looks like a Monarch aluminum French door. Is the gearbox knackard or just the cylinder? Can you explain the problem please.
If its the gearbox it is most likely an old Union lock that has been discontinued I'm afraid. Remove the metal plate covering the lock (2 screws) and see if it says Union behind it). Take a photo for us too.

Try these guys
http://store.northwesthardware.co.uk/ but I'm pretty sure they are no longer available. If you get really stuck give me a shout as I have a full 2nd hand Monarch door for sale and I could remove the gearbox for the right price.

Tell a lie, They may still be available http://www.ebay.co.uk/itm/Union-Mon...Profile-30-5mm-Back-Set-48mm-pz-/230774577939
You would have to (Very!) accurately check all the sizes and compare them to your one. 1mm or so out on a measurement and you may just buy a £60 paperweight

They are very helpful if you need to phone them before you buy.

Thanks for the response guys very much appreciated..

I am attaching photos of the door lock/handle from the opposite side.
As you can see the loose screws are the issue, I'm unable to tighten these hence want to replace full thing.

Is this just the case of unscrewing and then replacing the handle?

Thanks

It looks to me like someone has drilled and put a screw in the handle to keep it on.
Before you take it off, measure the handle centres for the turnkey and the spindle and source a replacement otherwise you may not be able to open or shut the door.
The handles should come off once the screws are undone.

Thank you

Without dislodging anything as of yet I'm attaching my drawing of some measurements of the front plate ive made which I think are:

1) from top to spindle
2) from top to turnkey
3) from top to bottom

Does this seem correct?
Which is the most important measurement I need to keep in mind and do I need to go instore
To find one with the exact measurement? (When looking online they don't seem to have the exact spec)

Need the PZ measurement, the overall height of the lock faceplate, the width of the faceplate, if the lock could be taken out then a photo of the case itself would be great, stickers and makers stamps really do help but it's probably a union monarch

This is how to measure the handles; https://www.handlesandhinges.co.uk/measure-a-door-handle/

But I'm not sure about the turnkey.

May have to do a search such as ' upvc handles with turnkey ' to get the right ones
