When it comes to securing your home or business, not all locks are created equal. As professional locksmiths working across Crawley and the surrounding areas, we’re often asked: “What’s the best lock I can buy?” The truth is, the best lock depends on a few key factors — and it’s crucial to know what to look out for.
At Crawley Locksmiths, we’ve put together this helpful guide to help you choose the right lock products for maximum safety, insurance compliance, and long-term reliability.
1. Look for the British Standard Kitemark
If you’re buying a lock for a front or back door, make sure it’s BS3621 approved. This British Standard means the lock has been tested for strength, durability, and security.
Many home insurance policies actually require this level of lock — especially on external doors. The British Standard Kitemark is a small logo engraved into the lock face, usually near the keyhole.
2. Check for Anti-Snap and Anti-Drill Protection
Modern burglars often use a method called lock snapping, especially on uPVC and composite doors with euro cylinder locks. If your lock doesn’t have anti-snap features, it could be vulnerable.
Choose a lock that includes:
- Anti-snap zones
- Anti-pick pins
- Anti-drill components
Brands such as Ultion, Yale Platinum, and ABS locks offer these features and are worth the extra investment.
3. Understand the Lock Type You Need
Different doors require different locks. For example:
- Mortice locks (5-lever) are commonly used in wooden doors.
- Euro cylinders are used in uPVC, aluminium, and composite doors.
- Night latches are often seen on front doors for added convenience.
If you’re unsure, Crawley Locksmiths can advise which lock suits your specific door and security needs.
4. Insurance and Police Recommendations
Always check that the lock meets your insurer’s requirements. Some insurers specify certain locks or standards (e.g., BS3621 or PAS 24). Locks that meet Secured by Design guidelines (backed by UK police) offer an extra layer of reassurance.
5. Avoid Cheap Imitations
We’ve seen it all — low-quality locks bought online that fail within months or don’t meet security standards. Invest in a reputable brand and have it fitted by a professional locksmith to ensure it’s installed correctly.
