Frequently Asked Questions
What makes a lock 'high security'?
A TS007 3-Star Kitemark rating means the cylinder resists snapping, picking, bumping and drilling. A BS3621 mortice deadlock adds a second line of defence. Together they meet most UK insurer requirements.
Are high security locks worth it for a standard home?
On roads with cylinder-snapping or kicking attacks, the upgrade typically costs less than a single insurance excess. We can advise on the risk level for your specific street in Tottenham.
Do you charge a callout fee?
No callout fee. Fixed quote before we start.
How long does a high security cylinder fit take?
Usually 20-30 minutes per door. A full upgrade with mortice and cylinder on front and back door runs 90-120 minutes.
Do you provide documentation for insurance?
Yes — an itemised invoice naming the specific lock, its BS/TS standard, and the date fitted. Accepted by all major UK home insurers.
Anti-Snap, Anti-Bump and Anti-Drill, in Plain Terms
Understanding the finer points of lock security is essential, especially for anti-snap, anti-bump, and anti-drill protection. These features keep our homes secure against common break-in techniques.
Anti-snap technology protects the lock cylinder from being snapped in half, a common method used by burglars. By having a reinforced section, it prevents the lock from breaking easily.
Meanwhile, anti-bump protection stops unauthorized access by preventing the lock from being manipulated using a bump key, a tool often used to quickly open doors.
Finally, anti-drill protection safeguards the lock mechanism from being drilled out. High-security locks incorporate hardened steel pins that resist drilling attempts, keeping the lock intact and functional.
Together, these features form a robust defense, keeping our homes and valuables safe. Investing in such locks means you can rest easy, knowing you're well-protected against modern burglary tactics.
