Describe the symptom, not a guessed part
Tell us whether the door is open or stuck closed, whether the handle moves and whether the key turns. Mention if the problem started suddenly or has gradually become worse. If you have already noticed different behaviour with the door open and closed, describe it; do not repeatedly test or force a failing door to diagnose it yourself.
The cylinder is only one part of the system
We look at how the cylinder, gearbox, locking strip and frame keeps work together, as well as the door's alignment. The aim is to identify the fault before selecting replacement parts. A new handle or cylinder may be appropriate, but it is not a universal cure; the assessment establishes whether adjustment, a component repair or mechanism replacement is needed.
Check the repair scope and parts availability
We explain which parts of the repair can be addressed and whether a matching component needs ordering. If safely visible, a maker's name on the door edge can help prepare the enquiry. Tell us if this is your only entrance or the property cannot be secured. Agree the initial work and any necessary return visit as separate parts of the quote.
Before you call
The handle will not lift. Should I pull harder?
No. Stop forcing the handle or key. Resistance may involve alignment or a mechanism fault, and additional force can worsen damage. Describe what happened and whether the door is currently open or closed.
Does a floppy handle always mean the gearbox has failed?
No. A loose handle can have more than one cause. The handle assembly and locking mechanism need assessment before a specific repair or part can be recommended.
Can you identify a replacement mechanism from a photo?
A clear image of accessible markings can help narrow the enquiry, but measurements and an inspection may still be needed. Ask how to send a photo; do not remove parts or expose the property to obtain one.
