High Security Lock Installation (Restricted & Pick-Resistant)
Protect your property with high-security locks that block common attacks—bumping, picking, drilling, and unauthorized key duplication. GOAT Locksmith and Doors installs restricted keyway cylinders and reinforced deadbolts for homes, storefronts, and offices across Toronto & the GTA.
What Makes a Lock “High Security”
- Restricted / patented keyways: duplicates only with authorization
- Pick & bump resistance: advanced pin stacks and mechanisms deter covert entry
- Drill & pry resistance: hardened inserts, reinforced strike and bolt
- Grade-rated hardware: commercial duty components for heavy use
- Clean alignment: proper strike and door fit for a smooth, fully thrown deadbolt
Our Installation Process
1) Site Review
Door material, backset, handing, frame and strike condition assessed before we recommend hardware.
2) Cylinder & Keyway Choice
We help you choose the right restricted system for your property and future growth.
3) Precision Fit & Reinforcement
Deadbolt bore/edge prepped accurately; reinforced strike and long screws into framing.
4) Key Control Setup
Authorized signers, key logs, and (if needed) master key levels.

High-Security Locks — FAQs
Do I need to replace my entire lock or just the cylinder?
Often a high-security cylinder retrofit is enough. We’ll advise if the existing hardware is compatible and in good condition.
Can you prevent unauthorized key copies?
Yes—restricted or patented keyways require authorization for duplication and maintain key control.
Is drilling still possible on high-security locks?
They include hardened components that resist drilling and tampering far better than standard locks.
Can this be part of a master key system?
Absolutely. We can integrate high-security cylinders into a Master Key Lock System.
