High-Security Locks
That Stop Intruders in Their Tracks
While CCTV and alarms provide visibility and alerts, your locks are the first barrier between a criminal and your home. Unfortunately, many standard locks can be bypassed in seconds using techniques like lock snapping. That’s where 3 Star high-security locks come in.
We supply and install insurance-approved 3 Star Euro cylinder locks that are resistant to snapping, drilling, bumping, and picking – all common methods used in forced entries. These locks are recommended by both locksmiths and insurers for properties across the UK.
Zone CCTV’s professional team ensures your locks are installed correctly and tested for performance. Whether it’s a main front door, patio, side gate or garage, we can help reinforce your access points for total peace of mind.
