Master Key Systems
Tired of carrying 20 keys? Want managers to have different access?
Custom master key system design and implementation for businesses in Virginia.
What to Expect
- 1Understand Your Needs - I ask about your building layout, staff roles, and access requirements. Who needs to access what? Who should have master access?(15-30 min consultation)
- 2Design the System - I create a key hierarchy chart showing which keys open which doors. You approve the design before any work begins.(1-2 days)
- 3Order Components - I source the right cylinders and blanks. For larger systems, I use restricted keyways that cannot be copied at hardware stores.(3-5 days)
- 4Installation - I install new cylinders in your existing hardware. The work is scheduled to minimize disruption to your business.(2-4 hours typical)
- 5Key Distribution - I cut all keys, label them clearly, and help you create a key control policy. You know exactly who has what access.(30 min)
Common Questions
How much does a master key system cost in Virginia?
Master key systems in Virginia typically run $30-50 per door for basic systems, $50-80 for restricted keyway systems. A 10-door office might cost $400-600 total.
What is a restricted keyway?
A restricted keyway uses a unique key shape that cannot be duplicated at hardware stores. Only authorized locksmiths can make copies. Better for businesses with turnover.
Can you add to an existing master key system?
Usually yes, if I can identify the system or if you have documentation. If not, I can design a new system that works with your existing hardware.
Commercial Lock Installation
Need locks that can handle heavy use? Security upgrades?
Professional installation of high-security commercial locks in Virginia.
What to Expect
- 1Site Visit - I look at your doors, traffic level, and security requirements. Commercial doors need specific hardware grades.(15 min)

- 3Quote - You get an itemized quote showing hardware costs and installation labor for each door. No surprises.(Same day)
- 4Installation - I install the locks, ensuring proper alignment and function. Commercial hardware requires precise installation to last.(30-60 min per door)

Common Questions
How much does commercial lock installation cost in Virginia?
Commercial lock installation in Virginia typically runs $150-350 per door including hardware and labor. High-security and specialty locks cost more.
What is the difference between commercial and residential locks?
Commercial locks are heavier duty, designed for high traffic. They use different standards: Grade 1 is highest (250,000 cycles), Grade 2 is medium, Grade 3 is residential.
Do you handle fire-rated doors?
Yes. Fire doors require specific hardware that maintains the fire rating. I am familiar with code requirements and install compliant hardware.
Panic Bars & Exit Devices
Fire code inspection coming up? Push bar not releasing?
Installation and maintenance of panic bars and exit devices in Virginia.
What to Expect
- 1Assessment - I examine your exit doors and current hardware. Is this new installation or repair? Fire-rated door or standard?(15 min)
- 2Code Check - I verify the installation meets fire code requirements. Exit devices have specific requirements based on occupancy type.(10 min)

Common Questions
How much does panic bar installation cost in Virginia?
Panic bar installation in Virginia typically runs $350-600 including hardware and labor. Rim devices are on the lower end, vertical rod and mortise panic on the higher end.
What is the difference between panic bar types?
Rim exit devices mount on the door surface (most common). Vertical rod devices lock at top and bottom (more secure). Mortise panic devices are built into the door (cleanest look).
Why does my panic bar not release?
Common causes: latch binding, misaligned strike, worn mechanism, or debris in the bar. I diagnose and fix the specific issue.
High-Security Locks
Need pick-resistant, bump-proof commercial locks?
Advanced security lock solutions for businesses in Virginia.
What to Expect
- 1lock upgrade reviews - I evaluate your current security and discuss your concerns. What threats are you worried about? What level of security do you need?(20 min)

- 3Quote & Ordering - You get a detailed quote. High-security locks often require ordering specific cylinders for your keying requirements.(3-7 days for materials)
- 4Installation - I install the locks, ensuring proper function. High-security locks have tighter tolerances and require precise installation.(30-45 min per door)
- 5Key Control Setup - I explain the key control system. High-security keys cannot be copied without your authorization through the manufacturer.(15 min)
Common Questions
How much do high-security commercial locks cost in Virginia?
High-security commercial locks in Virginia typically run $250-500 per door including hardware and installation. Medeco, Mul-T-Lock, and Abloy are premium options.
Why are high-security locks more expensive?
They use patented mechanisms that resist picking, drilling, and bumping. The key control system prevents unauthorized copying. You are paying for real security.
Can employees still copy keys?
No. High-security keys use restricted keyways. Only authorized dealers with your signature can duplicate keys. You control who gets copies.
Lock Rekeying
Employee left with keys? New tenant moving in?

What to Expect
- 1Scope the Job - Tell me how many doors need rekeying and why. Employee termination, new tenant, security concern? This affects the approach.(5 min call)
- 2Schedule - I can often do same-day rekeying for urgent situations. Otherwise, we schedule a time that works for your business operations.(Flexible)
- 3Rekeying - I rekey each lock to work with new keys. The old keys stop working immediately. Locks stay in the doors the whole time.(10-15 min per door)
- 4System Integration - If you have a master key system, I integrate the rekeyed locks into the existing hierarchy so everything still works together.(Included)
- 5New Keys - You get new keys for all rekeyed locks. I can make as many copies as you need right there.(10 min)
Common Questions
How much does commercial rekeying cost in Virginia?
Commercial lock rekeying in Virginia typically runs $25-50 per lock. A 10-door office would cost $300-500. Same-day emergency service may have an additional fee.
How fast can you rekey our locks?
For urgent situations like employee termination, I can often do same-day service. Each lock takes about 10-15 minutes to rekey.
Should I rekey or replace the locks?
If the locks are in good condition and you just need new keys, rekey. If locks are worn or you want to upgrade, replacement makes more sense.
Lock Repair & Maintenance
Lock sticking? Not catching? Cylinder worn out?
Expert repair and maintenance for all types of commercial locks in Virginia.

- 4Repair - I fix the issue: cleaning, lubricating, adjusting, or replacing worn components. Most repairs are done in one visit.(20-45 min)
- 5Preventive Check - While there, I check other locks and hardware. I would rather catch a problem now than have you call again next week.(10 min)
Common Questions
How much does commercial lock repair cost in Virginia?
Commercial lock repair in Virginia typically runs $75-200. Simple fixes like lubrication and adjustment on the lower end, part replacement on the higher end.
Is it better to repair or replace a commercial lock?
Depends on the lock and issue. If it is a quality lock with minor wear, repair. If it is cheap or badly worn, replacement is often more cost-effective.
Why do commercial locks fail faster than residential?
Higher traffic means more wear. A commercial door might cycle 100+ times per day vs 10 times for residential. That is why commercial-grade hardware matters.
