Changing Door Locks in South Lancing
Moved home, lost keys or living with a worn lock in South Lancing? A lock change should fit your door, work smoothly and stop old keys working. Here is how to choose the right approach.
Why people change locks in South Lancing
- Moving in. You rarely know how many keys previous occupants, tradespeople or agents still have.
- Lost or stolen keys – especially if they could be linked to your address.
- Worn or damaged locks that stick, catch or have been forced.
Lock Change in South Lancing
A lock change can help when keys have been lost or access arrangements change. We discuss compatible hardware and the condition of existing fittings.
Matching the new lock to your door
The right replacement depends on what is already fitted. Here is how common door types in South Lancing usually work:
| Door | Usual lock | What to consider |
|---|---|---|
| Timber front door | Mortice deadlock and/or rim night latch | Replacements must suit the existing cut-out and door thickness. |
| uPVC or composite door | Euro cylinder operating a multipoint mechanism | Often only the cylinder needs changing. It must be measured so it does not project too far. |
| Flat entrance door | Varies – latch, mortice or euro cylinder | May be a fire door; check before changing hardware. |
| Back, side or patio door | Euro cylinder, mortice or sliding-door lock | Often overlooked when a property changes hands. |
If your home insurance specifies a type of lock – policies often refer to British Standard BS 3621 for mortice locks on timber doors – check the wording before choosing a replacement. We can explain what is fitted, but the policy wording is what counts.
Permissions to check first
- Renting: check your tenancy agreement – permission from the landlord is usually needed.
- Shared entrances: locks on doors used by other households need the agreement of whoever is responsible for them.
- Owner-occupied homes: no permission is usually needed, but think about every external door, not just the front.
Cylinder change or full lock replacement?
- Cylinder only. On most uPVC and composite doors, changing the euro cylinder is enough to stop old keys working. It is usually the quickest and least expensive option.
- Whole lock. Needed when the mechanism itself is worn or damaged, or when a mortice lock or night latch needs replacing.
- Keyed alike. Several cylinders can sometimes be supplied to work with one key. Ask about this if you are changing more than one door.
- Finish and materials. On doors exposed to sea air, ask about finishes and materials that cope better with the conditions near the coast in South Lancing.

Lock Change questions
How do I know which cylinder size I need?
Euro cylinders come in different lengths for each side of the door. They are measured from the fixing screw, so it is best to have them measured rather than guess – an over-long cylinder can be easier to attack.
Can you change all the locks on a house in South Lancing in one visit?
Often, if the parts are available. Tell us how many doors and which types of lock when you call so we can plan the visit and give an itemised quote.
Do I need to change the lock or just the cylinder?
If the mechanism works well and the concern is who has keys, a cylinder change is often enough on uPVC and composite doors. Timber doors with mortice locks or night latches may need the lock itself replaced.
