Are You Really Locking Your Door? The Common New Build Security Fault Explained

Across the UK, thousands of homeowners in newly built developments are discovering a surprising design flaw that could be putting their security at risk, front doors that don’t automatically lock when closed.

While modern homes boast energy efficient windows, smart heating systems, and sleek design, one crucial feature is often overlooked: self-locking functionality.

The Issue: Doors That Don’t Lock Behind You

Many new build homes are fitted with doors that require residents to manually lock them using a key once shut. Unlike traditional front doors with a built in night latch or self-locking mechanism, these newer doors remain unlocked unless physically secured.

That means if you forget to lock the door whether after coming home with groceries or rushing out in the morning  your property could be left completely unsecured overnight.

A Common Oversight

According to Thames Locks Home Security Solutions, this issue is not unique to one development and many new build housing developments have been identified with this same fault.

This design oversight leaves many homeowners unknowingly exposed to risk, assuming their door has automatically locked behind them when it hasn’t.

The Solution: Quick, Seamless Installation

The good news? It’s an easy fix. Thames locksmiths can install self-locking functionality on existing doors without replacing the entire lock system.

This upgrade provides a night latch feature, meaning your door automatically locks when it closes, while still allowing entry with your existing key. It’s a seamless, same day installation that gives instant peace of mind.

“No more double-checking or worrying if you remembered to lock up, once the door is shut, your home is secure.” – Neil Bowe (Director of Thames Locksmiths)

Cost and Community Offer

Installation and materials typically cost £125 + VAT, but Thames Locksmiths offer discounts for neighbours who book together, a simple way to protect your entire street while saving money.
