Broken spring in door locking mechanism?

Ken2000

Hi, is it possible to replace or fix the spring behind this latch bolt, that doesn't spring back out anymore? Currently, it means that unless the door is locked, it won't be securely shut.

it should be. You'll have to remove handles & the whole mechanism from the door to do so though.

Thanks, as in the strip that runs the height of the door needs taking off, too?

I have just changed a couple of ours and got the fixings from Screwfix.  https://www.screwfix.com/p/era-zinc-188-93-tubular-mortice-latch-64mm-case-45mm-backset/9396t?_requestid=428705 yours will be different but hopefully you get the idea. 

Undo the screws on the door plate (the handle part).  Remove the handle and you will be left with a rod pocking though left to right, remove that.  Then you will need to remove the screws on the view that you have photographed.  Then remove the mechanism.  

You will need to check the measurements and purchase the correct latch.

The lock is on a uPVC door, and appears to be a multipoint locking system similar to this - https://www.screwfix.com/p/yale-adjustable-replacement-upvc-door-lock-53mm-case-35mm-backset/74544

Whilst it is possible that the spring in your selection might fit, if the OP's gearbox is riveted, getting to it is going to be troublesome.

OP - Take the gearbox out and look for a manufacturer and make/model number. If it is a current model, a replacement should be readily available. There are companies out there making alternative for discontinued models, but you need to hunt a bit harder for them.

I am no expert - having just changed a couple this weekend and never before in my life!  I did suggest it may not be the same and added the link to give the idea of what the OP may find when they undo the screws.

Now you've mentioned gearboxes I am out of my depth :-)

Thanks, I'm assuming that I would need to replace the whole gear box and that it's quite easy to remove.

Most likely it isn't riveted.

Open the lock first and look inside before buying an expensive replacement.

Once the door handle & Euro-cylinder is out, a few screws along the edge of the door need to be undone. Plenty of youtube and web pages to guide you. There may be a manufacturer name on the steel strip running up the edge of the door. If there is, that will narrow down your How-To searches.

Putting the darned thing back, not so easy. When I last did one, getting the linkages lined up took a bit of fiddling.
