High Security Locks Bolton – Maximum Protection for Homes and Businesses
Looking for a reliable high security lock in Bolton? CJW Locksmiths specialise in supplying and installing locks that offer superior resistance to picking, drilling, bumping, and forced entry. Whether you need to protect a home, office, or commercial property, we can recommend the right solution for your needs and budget.
What Are High Security Locks?
High security locks are designed with advanced mechanisms, anti-manipulation features, and hardened materials to protect against modern burglary techniques. They’re perfect for properties requiring an extra layer of defence and often meet or exceed insurance requirements.
We install and upgrade all types of high security locking systems, including:
- BS3621 Mortice Deadlocks and Sashlocks
- Anti-snap Euro Cylinder Locks
- 3-star TS007 Rated Locks
- Smart Locks with built-in tamper resistance
- Multipoint High Security Systems for uPVC and composite doors



When Might You Need a High Security Lock?
Recent Break-In or Attempted Entry
After a burglary or attempted intrusion, upgrading to a high security lock in Bolton adds immediate peace of mind and insurance-level protection.
Upgrading for Insurance Compliance
Many insurers require BS3621-rated locks for valid home cover. We install compliant locks and issue proof of fitting to meet policy standards.
Moving to a New Property
When you move into a new home or commercial unit, replacing existing locks with secure, tamper-proof models ensures previous keyholders can’t gain access.
Business or Office Security
Shops, offices, and units often hold valuable stock or equipment. High security locks offer better protection for entry points and storage areas.
Peace of Mind for Families
High security door locks are ideal for homeowners wanting better everyday protection without compromising usability or style.
Remote Entry with Smart Options
We also install digital and smart high-security locks that allow for keyless entry, code access, and remote control.
