Lock Installation & Replacement
Exterior, interior, and patio locks replaced or newly installed with quality hardware matched to your door type, material, and security needs.
Residential Locksmith Services in the GTA
Your front door is the first line of defence for your home and family. Our residential locksmiths handle everything from a single worn cylinder to a whole-home hardware refresh — working efficiently, communicating clearly, and leaving every door operating smoother than we found it.
Lock Repair
Sticking, loose, or worn cylinders and latch mechanisms restored to smooth, reliable operation — without replacing hardware that still has life in it.
Rekeying Services
Moving in, dealing with a lost key, or managing shared-tenant access? We rekey your existing locks so previous keys no longer work — faster and cheaper than full replacement.
Smart Lock Installation
Wi-Fi and Bluetooth smart deadbolts professionally installed, connected to your home network, and configured with user codes and remote access — we walk you through every setting.
Deadbolt Installation
Grade-1 and Grade-2 deadbolts added to entry and side doors for significantly stronger forced-entry resistance and better insurance compliance.
Home Lock Upgrades
A complete home assessment followed by a hardware refresh using anti-bump, anti-pick, and high-security cylinders where your current locks fall short.
Home Lockout Service
Locked out of your home? We use non-destructive entry techniques to get you back inside quickly without damaging your door, frame, or existing lock.
