A new lock for old uPVC door in Alderley Edge, Cheshire

I had a call the other day, A bed and breakfast in Alderley Edge. The handles on the main entrance door were floppy and just felt wrong. On stripping the door, the uPVC gearbox was found to be worn out, and the main spring to the mechanism broken. When I contacted my locksmith stockist in Stockport for a replacement, my worst fears were proven right - the lock was obsolete, and had been for a number of years!  We quickly found a close alternative and I returned  and fitted it, together with a new pair of handles, the job looked brand new!
