When you’re running a business or managing a property, securing your doors isn’t something to cut corners on. Still, many property owners attempt to save money by taking on new lock installations themselves—only to discover hidden costs that make the project more expensive than hiring a commercial locksmith from the start.
From unexpected tool purchases to security vulnerabilities and long-term repair costs, DIY can quickly become a financial and operational burden. In this guide, we break down the risks, compare cost factors, and explore smarter options for secure, professional results.
Why Businesses Attempt DIY Lock Installation (And What They Overlook)
It’s easy to understand the appeal of a do-it-yourself approach. Online videos make it look straightforward. Hardware store employees offer basic guidance. Installation kits promise simplicity. But most guides don’t account for the unique variables present in commercial settings—like metal doors, fire-code requirements, or integrated access systems.
Small errors in alignment, incorrect installation torque, or using the wrong backset can result in lock damage or weakened security. What begins as a quick fix often spirals into hours of frustration, multiple trips to the store, and a call to a locksmith anyway.
What DIY Installers Rarely Budget For
When pricing out a project, the obvious expenses—such as buying the lock itself—are easy to factor in. But the real costs go deeper.
1. Tools You Didn’t Know You’d Need
A basic door hardware installation kit can run between $40–$90. But commercial-grade door frames often require specialty drill bits, hole saws, and alignment templates to avoid structural damage.
2. The Cost of Mistakes
If a lock cylinder is misaligned or overtightened, it may jam, or worse—compromise the door’s integrity. The cost to remove a broken lock from a door or repair stripped screw holes can exceed the price of professional installation.
3. Security Gaps That Can’t Be Seen
Even if everything looks right on the surface, small misalignments in latch placement or strike plate depth create vulnerabilities. A lock that “sort of” latches is a liability. Criminals notice these gaps faster than you do.
4. Voided Warranties
Most manufacturers void warranties if the product is not installed by a certified technician. That means if something breaks in a month, you’re out the full replacement cost.
Comparing True Costs: DIY vs. Professional
Let’s break it down. Suppose you’ve selected a mid-tier commercial deadbolt:
| Item | DIY Estimate | Professional Install |
| Lock hardware | $95 | $95 |
| Tool purchases | $80 | $0 |
| Time spent (4 hours @ $40/hr value) | $160 | $0 |
| Fixing mistakes / re-drilling | $100–$200 | $0 |
| Total | $335–$435 | $150–$200 |
In this scenario, hiring a technician for door lock installation isn’t just easier—it’s more cost-effective.
Mistakes Common in DIY Lock Installation
Let’s address a few examples of what can go wrong when business owners skip professional installation.
Incorrect Door Prep
Different types of door locks for homes and businesses have unique specifications. Installing a Grade 1 deadbolt into a hollow-core door, for example, offers limited protection. Likewise, some locks require specific bore hole sizes or backsets that generic instructions don’t mention.
Misaligned Strike Plates
A quarter-inch misalignment can cause a latch not to fully seat—leading to door rattle, resistance when locking, or a false sense of security. Over time, this wears down both the bolt and the internal mechanism.
Ignoring Fire Codes or Building Regulations
In commercial settings, certain doors must meet fire rating standards or emergency egress requirements. A lock not rated for these conditions may put you in violation—and expose you to liability.
These DIY lock installation mistakes don’t just reduce functionality. They increase long-term risk and often require costly follow-up services to correct.
Handyman vs. Locksmith: Why It Matters
You might think any handyman can perform a new lock installation, but that’s not always true. Commercial systems—especially those that involve master key setups or smart access controls—require precision and expertise.
When comparing a handyman vs locksmith, consider:
- Handymen may be skilled with general repairs, but they may not be trained on rekey vs new locks compatibility, electronic lock configurations, or code compliance.
- Security professionals know how to handle a range of systems, from magnetic door locks to keyless access and panic hardware.
If you’re investing in safety, your installer should understand how different systems interact with one another.
Smart Locks, Higher Stakes
Businesses using keypads, card readers, or WiFi-enabled locks face an even higher risk with self-installation. Unlike simple deadbolts, these systems often require:
- Electrical connections
- Software setup
- Mobile app integration
- Fail-safe or fail-secure modes
A small mistake here may compromise not just the door, but your entire access network.
So, How Much Does It Cost to Hire a Locksmith?
It depends on the job. For a basic commercial-grade deadbolt install, expect to pay anywhere from $125 to $200. If you’re working with smart locks or high-security hardware, the rate may be higher due to complexity—but the benefits are worth it.
Avoiding expensive mistakes, maximizing product life, and meeting insurance or code standards should always factor into your total cost analysis.
Instead of asking how much does it cost, consider the better question: how much could DIY mistakes cost me in time, liability, and rework?
How to Choose the Right Lock (Without Guessing)
If you’re not sure which system best suits your business, schedule a site evaluation. You’ll get guidance on:
- The right types of door locks for homes vs commercial spaces
- Whether to upgrade or rekey (a common rekey vs new locks dilemma)
- Compatibility with your door material and frame structure
- Options for expanding access control in the future
Don’t just guess based on reviews or YouTube demos. Your building deserves a tailored security approach—not a one-size-fits-all kit from the hardware aisle.
Final Thoughts: Cut Risk, Not Corners
The upfront cost of DIY installation might seem attractive—but that’s only the beginning. Add in tool expenses, time lost, hidden risks, and potential lock failure, and suddenly your “budget fix” becomes a costly problem.
The safer and smarter route? Work with a licensed technician who handles door lock installation for commercial spaces every day. Your business, your customers, and your bottom line are too valuable to risk on shortcuts.
If you’ve been debating whether to call in a pro, now’s the time. Don’t gamble with your property’s first line of defense.
