As a homeowner, protecting your family and property is one of the most important decisions you’ll make. With burglary methods becoming more sophisticated, relying on old or basic locks simply isn’t enough. At Lock Fitter, we help thousands of UK homeowners upgrade to police-approved, high-security solutions that deliver real protection and everyday convenience.
Here’s our guide to building a complete home security system using the best products we stock and recommend.
Ultion 3 Star PLUS Cylinder – The Heart of Your Security
The Ultion 3 Star PLUS is our most popular cylinder for good reason. It carries the highest TS007 3-Star rating, Sold Secure Diamond approval, and the prestigious Secured by Design police-preferred specification. With advanced ALPS technology and a £5,000 anti-snap security guarantee (when paired with a compatible handle), it resists snapping, drilling, picking, and bumping far better than standard locks.
Whether you’re replacing one door or upgrading your whole home, this cylinder gives you professional-grade protection at a price homeowners can afford.
LockLock 2 Star Handles – Strength Meets Style
A strong cylinder needs an equally strong handle. Our LockLock 2 Star Security Handles are designed to work perfectly with Ultion cylinders. They resist leverage attacks and look modern on any uPVC, composite or timber door. Pairing the 3 Star PLUS cylinder with a 2 Star handle activates the full £5,000 burglary guarantee — real financial protection most standard setups don’t offer.
Ultion Nuki 2025 Smart Lock – The Future of Home Access
Want keyless convenience without compromising security? The All-New Ultion Nuki 2025 is a game-changer. With a built-in Wi-Fi bridge, auto-unlock when you approach, and full app control, it makes coming home effortless. Yet it still works with your physical Ultion key as backup — perfect if the battery or signal ever fails.
Ideal for busy families, remote workers, or anyone who hates fumbling for keys in the dark.
Keyed Alike System – One Key for Everything
Why carry a bulky keyring when one key can open your front door, back door, French doors, shed, garage and garden room? Keyed alike is now a **completely free upgrade** on every Ultion lock we supply. It’s one of the most popular requests from homeowners because it simplifies daily life without reducing security.
Ultion Window Handles & Additional Security
Don’t forget the windows. Our Ultion In-Line Window Handles (available in multiple colours) replace vulnerable espagnolette handles with secure, lockable versions. Add an Ultion Padlock for gates and outbuildings, and genuine Ultion replacement keys with free key caps to maintain your warranty.

Your home deserves the best defence — and you deserve peace of mind every time you turn the key (or tap your phone).
