Your windows and doors are where security starts. Even though the majority of locks will discourage casual intruders, determined burglars frequently know how to get past simple models. For this reason, an increasing number of Salisbury companies and homeowners are opting to upgrade to high security locks. When properly installed, these locks greatly increase the difficulty of breaking in, providing you peace of mind that your family and property are safe.
This tutorial describes the characteristics of "high security" locks, how to install them, and the fundamentals of installing security locks on windows and doors. We'll also examine why hiring a professional installer frequently results in long-term time, cost, and bother savings.
What Makes a Lock High Security?
Not every lock is made equally. Although it might keep your door closed, a cheap lock from a do-it-yourself store won't always keep a robber out. Extra measures that thwart popular break-in techniques are built into high security models.
These locks frequently have "anti-snap" designs that prevent thieves from breaking the lock in two, pins that make picking nearly impossible, and strengthened cylinders that resist drilling. Additionally, a lot of them have restricted keys, which prevent duplicates without ownership documentation.
Installing a high security lock gives you more peace of mind each time you close your door, in addition to making it more difficult for burglars to break in.
Installing a Door Security Lock
If you’ve ever wondered how to install a door security lock, it usually comes down to careful removal, accurate measuring, and precise fitting. For a standard euro cylinder, the process starts by unscrewing the fixing screw on the edge of the door, sliding the old cylinder out, and measuring from the centre of the screw hole to each end. Getting these measurements right is essential; if the lock sticks out too far it becomes vulnerable, while one that sits too deep may not operate properly.
Once the correct size is chosen, the new cylinder is fitted, screwed into place, and tested repeatedly to make sure it locks smoothly. For mortice locks in wooden doors, the job is more complex and involves chiselling the cavity accurately before securing the lock body and keep. While it’s possible to do this yourself, small mistakes—like choosing the wrong size or leaving a gap—can undermine the whole point of the upgrade. That’s why many Salisbury residents prefer to have a professional locksmith carry out the fitting.
Security Locks for UPVC Doors
Modern Salisbury homes often have UPVC doors with multi-point locking systems. If you’re thinking about how to install a security door lock on this type of door, the most common upgrade is to change the euro cylinder for a stronger, snap-resistant version. The steps are similar to those for a standard cylinder, but the multi-point mechanism must also be checked. If the gearbox or locking strip is worn, these may need replacing too.
Correct alignment is vital; if rollers or hooks don’t sit in the right place, the door may not close or lock properly. This is where experience really shows. A locksmith can carry out the upgrade quickly, adjust the mechanism, and make sure everything works perfectly before leaving.
Window Security Locks
Doors aren’t the only entry points that need protection. Windows, especially those on the ground floor, can be easy targets without proper locks. Installing security locks here is just as important as upgrading your doors. For UPVC windows, this may mean fitting new lockable handles or replacing the espagnolette strip that runs along the frame. Traditional wooden sash windows can be fitted with sash stops or restrictors that prevent them from being lifted open, while casement windows may need surface-mounted locks or keyed handles.
If you’ve been searching for advice on how to install window security locks, remember that placement is key. Locks should be easy for you to operate but positioned so that intruders cannot easily force them. Professional installation ensures the right balance between security and convenience.
The Risks of DIY Fitting
It’s tempting to think you can save money by installing locks yourself. And while some homeowners succeed, many run into problems.
A cylinder that protrudes even a few millimetres is at risk of snapping. A misaligned keep can mean the lock doesn’t engage fully. And forcing parts into place can crack a frame or strip a screw hole.
The result is often a lock that looks secure but isn’t. Worse, you might not even realise there’s a problem until it’s too late. Having a professional fit your locks avoids these risks and ensures the job is done right first time.

- After moving into a new property, when you can’t be sure who else has keys.
- If your locks feel stiff, loose, or unreliable.
- When your insurance requires British Standard or high security locks.
- Following a burglary or attempted break-in.
- Simply for peace of mind if your locks are old and outdated.
