How To Lock A uPVC Door Without A Key?
A uPVC door may be unlocked without a key by drilling off the lock barrel first. Using HSS bits, a pilot hole may be drilled, followed by a 10 to 12mm hole. Because the bigger bit is so little, it won’t even make a dent if you accidentally slam the drill bit shut.
On a Euro-style barrel, a screwdriver is enough to turn the cam. This tool can be used so that no one else can access it through the door except the person who snapped it. To fit perfectly, snapping barrels from the outside with the handle is difficult, but from the inside, with the handle is easy. Once removed, it gives you enough information about the barrel to strike it from the top, snapping it in half. This allows you to access the locking mechanism.
Since anti snapping barrels still snap, keep the cam in place so that no one can access it. You can change the plates and barrel screw with a new barrel. Also, you must replace the handle. Most uPVC users tend to apply the same procedure. They find it difficult to do from the exterior if there are no keys for the door. This is why the entire thing must be dismantled to continue locking a uPVC door without a key.
Sometimes, this process might not work with all doors. Removing the hinges and pulling the door back will not always favor you. You could have better access to the lock with a key, and making it keyless may weaken the lock. A likable situation may include slightly undone screws that can be broken with a hammer.
