Why High-Security Locks Matter
Most break-ins are not Hollywood safe-cracking. They are fast, repeatable attacks against average hardware. High-security cylinders and restricted key systems raise the difficulty, reduce successful picking attempts, improve drill resistance, and tighten control over who can duplicate keys.
- Stronger protection for exterior doors
- Better resistance to picking and drilling
- Key control through restricted keyways
- Professional install, alignment, and testing
High-Security Lock Options We Install
High-security is not one single product. The right upgrade depends on your door type, current hardware, key control needs, and whether you are protecting a home, business, or multi-tenant property. We help you choose what actually fits, then install it cleanly so the door closes and locks smoothly.
High-Security Deadbolts
Deadbolts are still one of the best exterior-door upgrades. High-security deadbolts use stronger components and improved cylinders to resist common attacks while staying simple to use every day.
Best for
- Front and back doors
- Side entrances and garage entry doors
- Rental properties where you want fewer lock failures
Restricted Keyway and Key Control
Standard keys are easy to duplicate, which kills accountability. Restricted keyway systems reduce unauthorized copies, which is critical for businesses, property managers, and homes with multiple keyholders.
Pair key control with structured access
If you also need hierarchy access (staff vs managers vs ownership), combine restricted keys with a properly designed master key system.
Keyless Entry and Smart Lock Upgrades
Keyless entry can improve convenience and access control, but the mechanical foundation still matters. We help you choose hardware that matches the door and install it so it is reliable, aligned, and secure.
Common add-ons
- Keypad entry for controlled access
- Audit-friendly access changes (better for turnover)
- Mechanical backup planning so you are not stranded
Professional Installation and Maintenance
Even premium hardware fails when the door is misaligned, the strike is weak, or the installation is sloppy. We install, test, and confirm smooth operation, and we can adjust or service doors that stick or bind.
What we check
- Door alignment and latch engagement
- Strike plate strength and fastener integrity
- Clean key operation and cylinder function

Quality-First ServiceWhat Makes a Lock High-Security?
High-security locks improve resistance to forced entry and reduce unauthorized key duplication. Most systems do this through upgraded cylinders, hardened components, controlled keyways, and tighter tolerances. For lock grades and performance standards, see: BHMA.
Common high-security features
- Drill resistance: hardened inserts and protective components that reduce cylinder drilling risk
- Pick resistance: tighter tolerances, security pins, or advanced cylinder designs
- Key control: restricted keyways to limit unauthorized duplication
- Stronger hardware: improved bolts and more durable materials
- Better strike support: stronger strikes and fasteners that improve real-world door strength
Rekey vs replace for security
Rekeying is best when the hardware is good but you need old keys to stop working. Replacement is best when the lock is worn, compromised, low-grade, or you want a true upgrade. For the access-control side of this decision, see: lock change and rekey services.
Key Duplication and Key Control
We can duplicate many key types and can also help you move into restricted key systems where duplication is controlled. For structured business access and accountability, combine key control with a master key system.
Lock Replacement for Better Security
If your lock is worn, low-grade, or compromised, replacement can be the fastest path to better protection. We install upgraded hardware with clean fit and proper testing so the door closes and locks smoothly.
Rekeying When Access Needs Change
Rekeying is the go-to option when keys are lost, stolen, or access needs change. It is usually faster and more affordable than replacing all hardware. Learn more at lock change and rekey services.
