I have patio doors that will not open, I can hear the bolts operating when I lift the handle but it is stuck shut. Anyone else had this, I am told that if the glass is remove I can get at the mechanism
If its a fairly new PVC door, then its unlikely that removing the glass will help. The PVC frame is a sealed "box" and you wont be able to see the lock mechanism by removing the glass.
I managed to open it by chance after 2 weeks of trying, it appears the bottom bolt is loose so I removed it, it works for now until I get a professional to fix it
