When people need a lock change

Five reasons people call us

Every lock change job is slightly different. Here are the most common situations — if yours matches one of these, you’re in the right place.

Most common

Just moved into a new home

You have no idea how many copies of the previous keys exist or who has them — past owners, estate agents, contractors, neighbours. A full lock change is one of the first things we recommend for any new property. Takes under an hour. Costs from £95 per door.

Common

Keys lost or stolen

If you’ve lost your keys — or had them taken — your current locks need changing. You don’t know who found them or whether your address is traceable from a key fob or other item they were with.

Common

After a break-in

Post-break-in lock changes are urgent and we respond 24/7. We replace damaged or compromised locks with BS3621 British Standard locks and anti-snap cylinders that meet insurance requirements — on the same visit wherever possible.

Planned

Insurance upgrade required

Many home insurance policies require British Standard BS3621 locks as a minimum condition of cover. If your insurer has flagged this — or you want to check before you need to — we can assess and upgrade to spec in a single visit.

Planned

Worn or failing lock

Stiff to turn, rattling, or no longer catching properly — locks wear out and older euro cylinders are increasingly vulnerable to snapping. If your lock is giving you trouble, it’s worth replacing before it fails entirely.

What we fit

Lock types & security options

All locks supplied meet British Standard or manufacturer security ratings. We’ll advise on the right option for your door type and insurance requirements.

Anti-snap euro cylinders

3-star British Standard cylinders designed to resist the most common modern burglary technique — lock snapping. The cylinder breaks in a designed weak point before the burglar can access the mechanism.

Police recommended

Ultion high-security cylinders

The highest-spec cylinder we fit. Ultion cylinders carry a £2,000 guarantee against burglary — anti-snap, anti-pick, anti-drill, anti-bump. Recognised by all major UK insurers.

Highest security

British Standard BS3621 mortice locks

The 5-lever mortice deadlock — the standard required by most UK home insurers. Fits into the body of the door for maximum strength. Essential on timber front and back doors.

Insurance standard

UPVC multi-point mechanisms

The locking mechanism inside UPVC doors that engages multiple bolts when you lift the handle. When this fails the door won’t lock or open correctly — we replace with a matching or upgraded mechanism.

Most common UPVC fault

Yale-type rim locks

Spring latch locks on the inside surface of timber front doors. We replace worn or outdated Yale cylinders with modern anti-snap equivalents and can upgrade to British Standard rim cylinders.

Common on older homes

Commercial lock changes

Offices, retail units, landlord portfolios — we carry out commercial lock changes with direct invoicing to business accounts. Master key systems available. Same-day response for urgent jobs.

Newly moved in?

The first thing to do in a new home

When you complete on a property, the solicitor hands over a set of keys. What they can’t tell you is how many other copies exist — keys cut for previous owners, tenants, estate agents, cleaning companies, maintenance contractors, or simply lost over the years and never reported.

A full lock change is the only way to be certain that nobody else has access to your home. It’s one of the most straightforward security steps you can take, and one of the best value — a typical Bristol house with front and back door takes around an hour and costs from £190.

Lock change FAQs

The questions we hear most from people considering a lock change or upgrade.

Lock changes start from £95 per door including labour and parts. Anti-snap cylinder upgrades start from £120. Ultion high-security cylinders from £150. UPVC multi-point mechanism replacements from £180. We always confirm the fixed price before starting — no call-out fee, no hidden charges.
Yes — always. You have no way of knowing how many copies of the previous keys exist or who has them. Previous owners, tenants, estate agents, contractors and tradespeople may all have had access over the years. A full lock change gives you certainty. A typical Bristol house with two doors takes around an hour and costs from £190.
Lock snapping is one of the most common burglary techniques in the UK — a standard euro cylinder can be snapped off using cheap tools in under 10 seconds, giving access to the door mechanism. A 3-star British Standard anti-snap cylinder is designed with a sacrificial break point that defeats this technique. Avon and Somerset Police actively recommend upgrading to anti-snap cylinders. We fit them from £120 supply and fit, usually in under 30 minutes.
British Standard BS3621 is the security specification most UK home insurers require as a minimum. It applies to both mortice locks (5-lever, fitted into the door body) and cylinder locks. If your insurer has flagged this as a condition of cover, or you want to check your property is compliant, call 07700 100146. Sam can assess your doors and confirm whether they meet BS3621 — and upgrade any that don’t, on the same visit.
A single door lock change typically takes 20–45 minutes. A full house — front door, back door and any patio or side doors — usually takes 1.5 to 2 hours. Sam carries the most common lock types for Bristol and South Gloucestershire properties on the van, so most jobs complete in a single visit without a return trip for parts.
Yes — and we respond 24/7 for post-break-in emergencies. We fit BS3621 British Standard locks and anti-snap cylinders to meet insurance requirements, and can advise on any additional security measures based on how the entry was gained. We carry the most common replacement parts on the van so the property can usually be secured in a single visit.
Yes — tenancy changeover lock changes are one of our most common jobs. We work for landlords and letting agents across Bristol and South Gloucestershire, with direct invoicing to business accounts available. Same-day response for urgent changeovers. Call 07700 100146 or see our Landlords & Letting Agents page for more detail.
