Front door levers catching when locking

[RobTi]

hi on my front upvc door with multipoint locking I have to give the handle an extra nudge when locking as it sticks just enough to stop the key turning, but works fine if I try it when opened, so I assume that after around 10 years it has dropped a bit and I need to Jack the hinges up a bit, if this is right can anyone tell me how, I know where the screws are.
Thanks

WD40 is not good for locks. It remains tacky so attracts dust and dirt into a lock which in the long term can make things worse
Silicone spray or Graphite spray is whats recommended.
Probably wouldn't do any harm but best not to invalidate any guarantees

Tacky? its oil in petrol suspension.Silicon attracts dust.

Just going by what I have been told and read many times on lock maintenance instructions. I'm no expert but this is what one lock manufacturer says:
This is what we find works best to keep your lock in its best working condition lubricate the lock cylinder. Do not use WD-40, WD-40 is a solvent, not a lubricant and will, in fact, remove any type of lubricant that is in the cylinder. Use a lubricant that has a silicone, graphite or Teflon base only. Make sure the lock cylinder is facing up and spray or pour the lubricant into the cylinder. Let it sit for 5 minutes. Place a rag on your workstation and turn the lock over onto the rag for a minute or so. This should be done several times a year to keep your lock working properly

I have read the same or similar many times in instruction for locks and locking gear I fit.
