Anti-snap euro cylinder lock being fitted in Manchester

Lock Replacement and Security Upgrades

The lock landscape has changed enormously in the last decade. Cylinder snapping, a technique where burglars break the exposed section of a euro cylinder to gain access, has become one of the most common methods of forced entry in the UK. Standard euro cylinders offer almost no resistance to this attack. Anti-snap cylinders are specifically designed to defeat it, featuring a sacrificial break line that protects the functioning part of the lock even if the outer section is snapped off.

We fit anti-snap cylinders from trusted brands including Avocet ABS, Ultion, Brisant Secure, and Yale Platinum. All of these locks carry TS007 3-star ratings or equivalent and provide protection against snapping, picking, bumping, and drilling. We measure your existing cylinder on site to ensure a perfect fit, and we can key-alike multiple locks so you only need one key for your entire property.

For wooden doors, we replace mortice deadlocks with BS3621-rated models that meet insurance requirements. We also upgrade nightlatches, fitting deadlocking versions that cannot be opened by pushing back the latch through the letterbox. Every replacement is installed to manufacturer specifications and tested thoroughly before we leave.

Moving into a new home? We strongly recommend changing all external locks. You have no way of knowing how many keys are out there for your existing locks. Previous owners, estate agents, builders, dog walkers, neighbours. A fresh set of locks gives you complete peace of mind from day one. We offer competitive multi-lock packages for new homeowners.

When to Replace Your Locks

Not sure if your locks need replacing? Here are the most common reasons our customers upgrade.

Just moved into a new property

This is the number one reason people call us for lock replacements. When you move into a new home, you inherit whatever locks the previous occupants had. You also inherit the risk that copies of your keys are floating around with people you do not know. Changing the locks on moving day is a simple, affordable step that gives you complete control over who can access your home.

Insurance company requires an upgrade

Many home insurance policies require BS3621-rated mortice deadlocks on wooden external doors and TS007 3-star cylinders on uPVC and composite doors. If your locks do not meet these standards, your insurer could refuse a claim after a break-in. We check your existing locks against your policy requirements and fit compliant replacements where needed.

Standard euro cylinders on external doors

If your front or back door has a standard euro cylinder with no anti-snap protection, it can be broken open in under thirty seconds using a pair of pliers. This is not an exaggeration. Cylinder snapping is quick, quiet, and requires no skill. Upgrading to an anti-snap cylinder is one of the most cost-effective security improvements you can make, and we can do it in about fifteen minutes.

Lock is worn, stiff, or unreliable

Locks are mechanical devices that wear down with use. If your key is getting harder to turn, the lock feels gritty, or it occasionally fails to engage on the first try, it is only a matter of time before it fails altogether. Replacing it now, on your terms, is far better than dealing with a total failure at an inconvenient moment. A lockout call-out will cost you more than a planned replacement.

After a break-in or attempted break-in

If someone has forced your lock, even if they did not get in, the lock is compromised. Damaged pins, a bent cylinder, or stress fractures in the lock body mean it is weaker than it was before. We replace the damaged lock with a high-security alternative and check the rest of the door hardware for hidden damage. The police crime reference number can often be used for an insurance claim on the cost.
