What the Texas DPS PSB rules cover

Texas Occupations Code Chapter 1702 requires a state locksmith license for locksmith activity in commercial settings. The definition covers:

• Installing, repairing, rebuilding, or rekeying mechanical locks on commercial properties
• Originating keys (cutting a new key when the customer doesn't have one)
• Designing, installing, or maintaining master-key systems
• Opening locks for customers (lockouts) on commercial properties
• Servicing safes for compensation
• Servicing automotive locks and keys for compensation

Residential work in your own home or a property you own is exempt. Residential work as a paid service provider is in a gray area that the law arguably covers. The practical line: if money is changing hands for lock-specific work on a property that isn't yours, hire someone with a DPS PSB license. The legal exposure for unlicensed activity (Class A misdemeanor, civil penalties up to $5,000) falls on the operator, but customers can be on the hook for unpaid work if a contract was signed with an unlicensed provider.

Cost comparison on a real Houston example

Scenario: 4-cylinder Houston home rekey after a new homeowner moves in. Let's compare the paths.

Locksmith path. $150 to $300 total for the rekey. One trip, 30 to 45 minutes on-site. Locksmith brings pin kits and key blanks. Customer leaves with a fresh set of keys cut on-site. Old keys (previous owner, agents, neighbors) no longer work. Done.

Handyman path. $50 to $80 per hour for the time. The handyman has to either (a) buy a Kwikset SmartKey rekey tool and only handle Kwikset cylinders (most Houston homes have at least some Schlage, so this path covers maybe 50 percent of the doors), or (b) just replace the deadbolts entirely instead of rekeying, which means $100 to $250 per door installed for the new hardware. The handyman path either leaves you partially rekeyed or costs more than the locksmith path. Plus the handyman path requires you to source the hardware yourself, which is another 60 minutes at Home Depot.

For rekeying specifically, the locksmith is almost always cheaper end-to-end despite the higher hourly equivalent. This is the pattern for most lock-specific work.

What handymen genuinely do better

A few categories where the handyman is the better call:

Door alignment and hinge work. A door that sticks at the top corner because the upper hinge has loosened over years is a handyman job. The fix is mechanical (longer hinge screws, sometimes a shim, sometimes a hinge replacement). The locksmith bills the same kind of hourly rate but their core skill isn't relevant.

Frame patching and refinishing. Post-break-in frame damage needs wood filler, sanding, and matching paint. A handyman with finish-carpentry experience does this well. A locksmith does the lock side of the same repair and coordinates with the handyman or contractor for the frame side.

Slab door replacement. If the door itself is damaged (kicked in, rotted at the bottom from sprinkler exposure, warped from Houston humidity), the handyman or contractor handles the replacement. Locksmith comes in after the new door is hung to install the lock hardware.

General mechanical adjustments. Sticky deadbolt that's actually a misaligned strike plate. Hard-to-turn knob that just needs WD-40-free lubricant on the latch. Sliding patio door that won't latch because the track is dirty. Handyman.

When the handyman should call a locksmith mid-job

A handyman who finds themselves on a job that's drifted into lock-specific work should call a locksmith. Common moments:

• Customer mentions they lost a key and want to "rekey." (Handyman doesn't have the pinning kit.)
• Smart lock install on an older Houston bungalow turns out to need door prep that involves milling a fresh mortise pocket or borehole. (Beyond standard handyman scope.)
• Strike plate alignment reveals an underlying issue with the deadbolt cylinder itself. (Needs locksmith diagnostic.)
• Customer asks about a master-key system for their home office. (Locksmith-only.)
• Lock-related work on a commercial property. (Texas DPS PSB license required.)

We work with several Houston-area handyman companies in this exact pattern. They handle the mechanical side, we handle the lock side. The customer gets the right specialist for each piece of the job and the total cost stays reasonable.
