What this service includes
Lock Replacements work we take on
Locks get changed for practical reasons: a tenancy ends, keys go missing, a door stops locking properly or a mechanism finally gives out. We fit replacements that suit the door rather than whatever is cheapest.
This is a common request from landlords and letting agents between tenancies, and we can attend the property directly once access is arranged.
- Euro cylinders
- Replacement cylinders in the correct size, including anti snap options for external doors.
- UPVC mechanisms
- Multipoint locking gearboxes replaced when the handle lifts but the door will not lock.
- Mortice locks
- British Standard five lever locks fitted to timber doors, including insurance requirements.
- Handles and furniture
- Door handles, letterplates, hinges, spy holes and chains fitted or replaced.
- Door adjustments
- Dropped and misaligned doors adjusted so the lock engages without forcing.
- Keyed alike sets
- Several doors set to a single key where that suits the property.
Common customer needs
The reasons people usually call us about this
- A change of tenancy where the previous keys are unaccounted for
- A key snapped in the lock or a lock that no longer turns
- A UPVC door that will not lock even though the handle lifts

FAQs
Lock Replacements questions
If your question is not covered here, call or send a message and we will answer it directly.
- Are you a locksmith for lockouts?
- We are not an emergency lockout service. We handle planned lock replacements, door security upgrades and mechanism repairs during normal working hours.
- How do I know what lock I need?
- Send us a photo of the door and the edge of the door where the lock sits and we can usually tell you. We measure exactly on site before fitting.
- Can you fit anti snap cylinders?
- Yes. For external doors we generally recommend a three star rated anti snap cylinder, and we will explain the difference in cost before ordering.
- Can several doors use one key?
- Yes, cylinders can be supplied keyed alike so one key opens front, back and side doors. This is popular with landlords managing several properties.
