Here's something most business owners get wrong: they wait until after a break-in, a fired employee, or a lost master key to upgrade their office locks. By then, the damage is done. Stuart Locksmiths handles office lock upgrades in Stuart, FL every week, and the businesses that call us proactively spend a fraction of what the reactive ones do.
An office lock upgrade in Stuart typically runs $150 to $800 per door depending on hardware grade, lock type, and whether you need electronic or mechanical systems. Most single-office jobs take 2 to 4 hours. Multi-suite commercial buildings along US-1 or the industrial corridor near Monterey Road can take a full day. We'll give you a firm quote before we touch anything.
Stuart Locksmiths is licensed, insured, and has completed over 1,400 commercial lock jobs across Martin County since 2009. We serve the entire Stuart area including downtown, Confusion Corner, the Kanner Highway corridor, and out toward Palm City.

Why Stuart Offices Are Upgrading Their Locks Right Now
Commercial burglaries in Martin County spike every summer. Seasonal staff turnover is the main culprit, along with businesses that haven't changed locks since they moved in. If your office is still running Grade 3 residential-grade hardware on a commercial door frame, you're not protected the way you think you are.
ANSI/BHMA Grade 1 commercial locks withstand 250,000 open/close cycles and resist significantly higher forced-entry torque than Grade 3 residential hardware. Most office doors in older buildings near Colorado Avenue or Stuart's historic downtown district are running hardware installed 10 to 15 years ago. That hardware wasn't designed for today's threat profile.
Rekeying helps, but it doesn't solve a worn cylinder, a failing latch mechanism, or a door that doesn't seat properly in the frame. Sometimes an upgrade is the only real answer. Our Commercial Lock Rekey service covers situations where the hardware is still sound, but full replacements are a different conversation.
| Lock Grade | Forced Entry Resistance | Avg. Time to Defeat | Common Use |
|---|---|---|---|
| ANSI Grade 3 | Low | Under 60 seconds | Residential interior |
| ANSI Grade 2 | Moderate | 2 to 5 minutes | Light commercial |
| ANSI Grade 1 | High | 8 to 15 minutes | Standard commercial |
| High-Security (UL437) | Very High | 30+ minutes | Banks, medical, legal |

How Our Office Lock Upgrade Process Works
- Security walk-through. A Stuart Locksmiths technician surveys every entry point, notes door frame condition, existing hardware grade, and any compliance requirements like ADA clearance or Florida Fire Code egress rules. This takes 20 to 35 minutes for a typical office.
- Written quote, no pressure. You get itemized pricing on paper before anything happens. Hardware brand, labor, and any door prep work are listed separately so you know exactly what you're paying for.
- Hardware sourcing and scheduling. We stock Schlage, Medeco, Mul-T-Lock, and Alarm Lock in the van for most standard upgrades. Specialty orders for high-security or access control hardware typically arrive within 2 business days.
- Installation and testing. Every lock gets installed, tested under load, and adjusted to the frame. We don't leave until every door opens and closes correctly on the first try, every time.
- Key control documentation. You get a written key record showing exactly how many keys exist, which doors they operate, and who has them. That paperwork is worth more than people realize when staff turnover happens.
Need a Master Key System built into the upgrade? We design those during step one so the pinning is done right the first time, not retrofitted later.

Lock Upgrade Options for Stuart Businesses
Not every office needs the same solution. Here's what we actually install most often in Stuart.
Mechanical High-Security Locks
Medeco and Mul-T-Lock cylinders are pick-resistant, drill-resistant, and come with restricted keyways so copies can't be made at the hardware store down the street. These are the right choice for server rooms, executive offices, and anywhere sensitive records live. See our full High-Security Lock Installation page for details.
Smart Locks and Keypad Entry
Eliminate physical keys entirely for common areas and conference rooms. Audit trails show you exactly who unlocked what door and when. Great for offices with rotating staff or contractors. Our Smart Lock Installation service covers brands like Schlage Encode, Yale, and Kwikset Halo.
Access Control Integration
Fob and card readers, tied to a management portal you control from your phone. Add and remove employees in under 2 minutes without touching the hardware. Our Access Control Systems page walks through the full scope of what's possible.
Panic Bar Upgrades
Florida Fire Code requires panic hardware on certain commercial egress doors. If your office has a rear exit that still has a standard knob or lever, that's a code violation waiting to be flagged. Check our Panic Bar Installation page for compliance specifics.
Why Stuart Locksmiths for Your Office Upgrade

- Hardware we actually stand behind. We carry Grade 1 commercial hardware from Schlage, Medeco, and Mul-T-Lock, not the rebranded import hardware some shops sell at premium prices.
- Flat-rate quotes. The number we give you before the job is the number on the invoice. Every time.
Frequently Asked Questions
How much does an office lock upgrade cost in Stuart, FL?
Most single-door upgrades run $150 to $400 depending on hardware grade. Smart lock installations land between $285 and $550 per door. Full access control systems start around $600 per door and go up from there. Stuart Locksmiths provides written quotes before any work starts, so you'll know the exact number upfront.
How long does it take to upgrade locks in an entire office?
A 3 to 5 door office typically takes 3 to 5 hours. Larger suites with 10 or more doors may need a full day. We'll give you a realistic time estimate during the walk-through so you can plan around it.
Do I need to replace the whole lock or just the cylinder?
Depends on the existing hardware condition and your security goals. If the door hardware is Grade 1 commercial and structurally sound, upgrading just the cylinder to a high-security model is often the right call. If you're running older Grade 2 or Grade 3 hardware, replacing the whole unit usually makes more sense long-term.
Can you upgrade our office locks without disrupting business hours?
Yes. Most commercial lock upgrades are quiet, fast jobs that don't require office closure. We work around your schedule and can handle installations early morning or after hours for businesses that can't afford interruptions.
Should I rekey or fully upgrade my office locks after an employee leaves?
Rekeying works if the hardware is in good shape and you just need to invalidate old keys. If the former employee had a key for an extended period, or if the lock hardware is worn or outdated, a full upgrade gives you a clean slate on both the hardware and key control. Stuart
