Where’s the job?

Scope of Works

• inspect and assess existing lock, cylinder and door/frame condition

• remove and replace euro cylinder or mortice sash lock depending on the fault

• fit anti‑snap/anti‑bump cylinder or upgrade to a higher‑security multipoint mechanism if requested

• adjust or replace keeps and strike plates and rebalance the door for smooth operation

• cut and supply up to three keys and test all fitted locks

• carry out minor carpentry to secure a new lock where required (packings, strike reinforcement)

Typical Cost

Time on Site

simple cylinder swap: 30–60 minutes; mortice or full multipoint replacement: 1–3 hours; time can extend if frames are rotten, bespoke parts are needed, additional carpentry is required or access/permission issues arise

Questions to Ask Your Tradie

• are you insured and registered with a relevant trade body

• do you provide a written quote and a parts and labour warranty and for how long

• will replacement locks meet my home insurance requirements and can you provide certification

• which brand and security rating do you recommend and can you fit an anti‑snap cylinder

• will you need to return with parts not held in your van and how will return visits be charged

• do you cut extra keys on site and how many are included in the price

How to Avoid Surprises

• ensure clear access to the door and move furniture from the working area

• provide parking details or permits and advise if access involves stairs or narrow corridors

• secure pets and keep children away while work is carried out

• confirm who can approve lock changes (landlord, freeholder or management company) for communal doors

• tell the tradie about previous forced entry, rotten frames or non‑standard doors before arrival so they bring correct parts and PPE

• be prepared for short delays if non‑standard parts must be ordered and ask about temporary security if the lock is removed
