When Does a Lock Change Make Sense?
Better security / upgrade
Compare a straightforward replacement with a suitable higher-security cylinder for your door and existing hardware.
Tenant or key-holder change
Arrange fresh keys for an agreed property handover when previous keys should no longer operate the lock.
Planned replacement
Replace an existing domestic lock with a suitable option for the door, whether like for like or a chosen upgrade.

Locks That Can Be Changed
Suitable replacements for domestic doors include:
- Euro-profile and front-door cylinders
- Mortice and sash locks on suitable timber doors
- Rim locks and night latches
- Suitable composite-door locks
- uPVC or composite cylinders where the multipoint mechanism works correctly
The door, lock dimensions and existing handles or security hardware determine what fits. A cylinder change does not automatically require replacement of a working multipoint mechanism.
If the gearbox, multipoint mechanism or alignment is faulty, see uPVC and composite door repairs.
Standard Replacement or Security Upgrade?
Standard euro cylinder
A basic replacement option for fresh key control. It should not be assumed to offer the tested attack resistance of a higher-rated cylinder.
TS007 1-star cylinder
A different rating from a 3-star cylinder. Suitable TS007 2-star security handles or protection can form part of the overall security setup; a 1-star cylinder alone is not a 3-star cylinder.
TS007 3-star / higher-security cylinder
A TS007 3-star cylinder is tested for resistance to snapping and other attacks under that rating. Anti-snap protection varies by product and security level.
Correct cylinder length and fitting matter. Existing door hardware and your requirements affect suitability, so the final option is confirmed after assessment. Not every door needs a 3-star cylinder.
British Standard replacement options can be discussed where suitable. Standards describe different products and tests; they do not all provide identical protection. Check any specific insurance requirement before choosing a lock. No lock is unbreakable.

Lock Change Questions
How much does it cost to change a door lock in Leeds?
Standard euro cylinders start from £45, higher-security or anti-snap cylinders from £65, mortice and sash locks from £45, and rim locks or night latches from £25. These are category guide prices, not fixed fitted totals. Lock type, size, security specification, existing hardware and work required affect the quote. No call-out fee and no VAT; the price is agreed before work starts.
Can you replace just the euro cylinder instead of the whole lock?
Yes, where the cylinder can be replaced separately and the rest of the lock and door are working correctly. A suitable cylinder change gives you new keys without replacing a working multipoint mechanism.
What should I do if my house keys are lost or stolen?
Tell me whether you still have access and which locks the missing keys operate. We can discuss changing those locks to restore key control. If you are locked out, use the house lockout service for access help.
What is the difference between a standard cylinder and a 3-star anti-snap lock?
A standard cylinder is a basic replacement option. A TS007 3-star cylinder has tested resistance to snapping and other attacks under that rating. A TS007 1-star cylinder is a different rating and is not equivalent on its own. The right option depends on the door, cylinder size and existing security hardware.
Can you change locks on uPVC and composite doors?
Yes. A suitable cylinder can be changed where the multipoint mechanism and door alignment are working correctly. Gearbox, multipoint or alignment faults belong with the uPVC and composite door repair service.
Should I change the locks after moving house?
A lock change can restore control over who has working keys when the history of spare keys is uncertain. See the moved-house lock guide for advice specific to moving into a property.
Are replacement parts covered by a warranty?
Parts supplied and fitted by Locksmith Leeds MobileLS Ltd are covered by a 1-year warranty, subject to normal use.
