5 Fascinating Facts About Locks You Probably Didn’t Know

We use a lock every day—turn the key, shut the door, job done. But behind that simple action lies a rich history and some truly clever technology. As your trusted local locksmith in Romsey, we’ve spent years helping residents across Cupernham, Whitenap, North Baddesley, and surrounding areas keep their homes and businesses secure.

Here are five surprising facts about locks you might not know—plus how they matter to you right here in Romsey.


1. Locks Have Been Around for Over 4,000 Years

A Brief Look at Lock History

The first known lock dates back to around 2000 BC in ancient Mesopotamia. These early devices were made from wood and operated using a simple pin tumbler design.

Today’s locks have evolved into high-tech security tools with features like anti-snap protection, smart access, and drill-resistant mechanisms. Whether you live near Broadlands or in the heart of Romsey, modern locks offer peace of mind that an ancient lock never could.


2. Master Key Systems Are Older Than You Think

From Ancient Egypt to Modern Romsey

The concept of a master key system—where one key opens several locks—originated in ancient Egypt. Back then, they were made of wood and rope. Now, precision engineering makes them secure and practical for multi-door setups.

We regularly install modern master key systems for local landlords, offices, and schools in Romsey, Shootash, and the Romsey Industrial Estate, making property access more efficient and secure.


3. Lock Picking Is as Old as the Lock Itself

Security Has Always Been a Challenge

As long as there have been locks, there have been people trying to open them without keys. Over time, this has led to major advances in lock design.

That’s why we recommend anti-pick locks—like those from Ultion and ABS—for properties in Braishfield, Timsbury, and Michelmersh. If your lock is older or basic models, you may be more vulnerable than you think.


4. High-Security Locks Do More Than Just Lock

Advanced Protection for Your Romsey Property

Some of the best locks on the market today do far more than stop a key from turning. High-security models are built to withstand common attack methods like:

  • Lock snapping
  • Lock bumping
  • Drilling
  • Picking

We supply and fit Ultion, Yale Platinum, and ABS 3-Star locks across Romsey and the surrounding villages, giving homeowners and businesses extra peace of mind.


5. Your Insurance Might Depend on Your Locks

Are Your Locks Up to Standard?

Many insurance providers require your locks to meet British Standards—typically BS3621 for mortice locks or TS007 3-Star for euro cylinders. If your locks don’t meet these requirements, your insurer may reject claims following a break-in.

We often carry out lock upgrades for homes in Awbridge, Crampmoor, Halterworth, and other parts of Romsey to ensure compliance and improve overall security.
