Hi,
Help!
The lock mechanism on my uPVC front door has bust and I can't lock it. The door was installed by Coldseal (now out of business) about five years ago. I've got the lock out and it definitely appears to be the 'core' locking mechanism at fault. No manufacturer's name on the lock so at a guess it's Coldseal own-brand. The unit is sealed shut and I can't see myself getting it apart to diagnose or fix the fault.
How best to proceed? Needless to say, B&Q / Wickes / etc. don't stock them. I don't know whether these are standard-ish parts or manufacturer specific, whether my local locksmith or double glazing fix-it man will be able to assist, whether to nip to the local council tip and see if I can maybe salvage a uPVC door from there and take the lock out of it, etc. etc.
Cheers for any useful advice. No I'm not going to give you my address and tell you when I'll be out. :-)
