How much does it cost to install a smart lock?

The labor cost to install a smart lock typically ranges from $100 to $200 per lock. This is higher than standard locks because it involves programming, app setup, and precise door alignment to ensure the motor operates smoothly.

Is it cheaper to install locks myself or hire a locksmith?

DIY is cheaper upfront as you save on labor ($100+). However, hiring a locksmith ensures the deadbolt aligns perfectly with the strike plate. A misaligned DIY installation can lead to lock failure or reduced security.

How do locksmiths calculate labor costs?

Locksmiths charge a base 'Service Call' fee to cover travel and overhead (approx $65-$85). Then, they charge a 'Per Lock' fee ($30-$60) for the actual work of removing the old hardware and fitting the new one.

What is the difference between Grade 1 and Grade 3 locks?

Grade 3 is standard residential quality (cheapest, easiest to pick). Grade 1 is commercial heavy-duty security (most expensive, hardest to break). For home exterior doors, Grade 2 is the recommended balance of cost and security.

How Much Should It Cost to Replace a Door Lock? (2026 Guide)

Planning to upgrade your security? Here is the real cost of labor and hardware.

When calculating the cost to change door locks, you need to separate two things: the cost of the labor (the locksmith’s time) and the cost of the hardware (the lock itself).

🛠️ Labor Cost

$75 – $150

Per trip (Service Call). Plus $30-$50 per lock for installation.

🔒 Hardware Cost

$30 – $300+

Depends heavily on quality (Grade 1 vs Grade 3) and brand.

Labor Costs: Fresh Install vs. Replacement

The price of labor depends on whether the door already has holes drilled.

Service Type	Description	Est. Labor Cost
Standard Replacement	Removing old lock and fitting new one into existing holes.	$30 – $60 per lock
Fresh Installation	Drilling new holes into a wood or metal door for a deadbolt.	$75 – $150 per lock
Smart Lock Install	Installing electronic keypad/Wi-Fi locks (setup & calibration).	$100 – $200 per lock

*Note: These labor prices are in addition to the initial Service Call fee ($65-$100).

Hardware Costs: You Get What You Pay For

Not all locks are created equal. The American National Standards Institute (ANSI) grades locks by security and durability:

Grade 3 (Residential Standard): $20 – $50. Found at big-box stores. Good for interior doors, okay for entry, but easiest to pick or force.
Grade 2 (Light Commercial / High-End Home): $60 – $150. Recommended for all exterior home doors. Stronger metal, harder to pick. (Brands like Schlage, Kwikset Signature).
Grade 1 (Commercial / Maximum Security): $150 – $400+. Used in schools, hospitals, and high-security homes. Nearly impossible to kick in.

Pro Tip: You can buy your own locks from Home Depot or Amazon and just pay us for labor! However, if you buy from us, we usually offer a warranty on the hardware itself.

Is it Cheaper to Use a Locksmith or DIY?

Many homeowners ask: “Can’t I just watch a YouTube video and do it myself?”

The DIY Route

Cost: Price of lock + Screwdriver.

Risk: If the door is slightly misaligned (which is common), the deadbolt won’t extend fully. A deadbolt that isn’t fully extended provides zero security. Also, installing a smart lock incorrectly can strip the motor, voiding the warranty.

The Professional Route

Cost: Hardware + ~$100 Labor.

Benefit: We align the strike plate so the door closes smoothly without pushing/pulling. We ensure the deadbolt “throws” completely for maximum security. We carry specialized tools to fix sagging doors.
