Lock change: two cylinders on uPVC French doors in Birmingham
In October 2026 our locksmith replaced both cylinders on a set of uPVC French doors in Birmingham (B8) on the day they were booked. The doors were thick, so they needed longer 95mm cylinders.
The job
- Where: Birmingham (B8), October 2026
- Doors: white uPVC French doors
- Fitted: two 95mm euro cylinders (45/50)
What we did
- Measured each cylinder from the centre screw: 45mm on one side and 50mm on the other.
- Fitted both new cylinders.
- Checked both doors locked and the cylinders did not stick out too far.
Worth knowing
- Not every door takes a 70mm cylinder. The most common size we fit is 70mm (35/35), but thicker doors need longer ones.
- A cylinder should not stick out more than about 3mm. A cylinder that projects too far is easier to snap.
Shop anti-snap cylinders.
