ABOUT US

How Lock & Protect secures your home

Most break-ins happen through vulnerable, standard locks that lack modern protection. Lock & Protect assesses every access point to recommend high-security upgrades that deter intruders – protecting your property, your family, and your peace of mind.

WHAT WE DO

Comprehensive Protection Upgrades. Whatever Your Home Needs – We Are Ready.

3-Star Anti-Snap Cylinders

Protect your euro cylinder doors against lock snapping, drilling, and picking. We install TS007 3-star diamond-rated cylinders for ultimate defense.

BS3621 Mortice Locks

Key turns but door won’t open? Usually a mechanism fault, not the lock. We diagnose correctly and fix the actual cause.

Multipoint Locking Enhancements

Strengthen uPVC and composite entry doors with upgraded gearboxes, heavy-duty hook bolts, and high-security handle armor.

Patio & Window Lock Upgrades

Secure weak secondary entry points. We fit heavy-duty window locks, sliding patio door bolts, and French door security restrictors.

Insurance Security Audits

Ensure your home locks meet strict insurance policy standards. We assess, recommend, and fit fully certified locks on the same visit.

Smart Locks & Keyless Access

Modernize your home entry with heavy-duty keyless deadbolts and smart lock systems for effortless, key-free security control.

COMMON QUESTIONS

Home Security Upgrades – Your Questions Answered

Why should I upgrade my standard door locks to anti-snap cylinders?

Standard euro cylinder locks are vulnerable to lock snapping, a method intruders use to break into homes in under 10 seconds. Upgrading to TS007 3-star anti-snap cylinders reinforces your doors with anti-drill, anti-pick, and snap-resistant steel barriers that block forced entry completely.

Will upgrading my locks help satisfy my home insurance policy?

Yes. Most home insurance providers require main entry doors to be fitted with British Standard BS3621 approved locks or 3-star rated cylinders. We fit fully certified hardware and provide insurance-compliant solutions on the same visit.

Can you upgrade locks on existing uPVC, composite, and timber doors?

Absolutely. We retrofit high-security locks, heavy-duty handles, and anti-snap cylinders onto all existing door types without replacing the entire door structure or damaging the surrounding frame.

How do I know which security upgrades my home needs?

Our certified locksmiths conduct a full security audit of your front, back, patio, and window locks upon arrival. We identify vulnerabilities and provide a clear, fixed-price quote tailored to your property before starting any work.

Fantastic security assessment! They identified weak points in our lock mechanisms that we hadn’t noticed and swapped them for anti-drill, anti-snap models instantly. 5-star experience.
