Is it Cheaper to Use a Locksmith or DIY? The Hidden Costs Explained
In the age of YouTube tutorials and massive hardware stores, taking the “Do-It-Yourself” route has never been more popular. When a lock gets sticky, you move into a new house, or you want to upgrade your home security, it is natural to ask: is it cheaper to use a locksmith or DIY?
At first glance, the math seems simple. If you install a lock yourself, you only pay for the hardware off the shelf and save on the locksmith’s labor and call-out fees. However, home security is rarely that straightforward. A poorly installed lock is essentially the same as having no lock at all. In this guide, we will break down the true costs, the hidden risks of DIY, and when hiring a professional actually saves you money in the long run.
The True Cost of DIY Lock Installation
If you are a highly skilled handyman with a garage full of specialized tools, DIY can indeed save you some money upfront. But for the average homeowner, the DIY route often comes with unexpected expenses:
- Buying the Wrong Hardware: Doors come with different thicknesses, and lock mechanisms have specific “backset” measurements (the distance from the edge of the door to the center of the keyhole). Buying the wrong size means multiple frustrating trips to the store, and trying to force it to fit can permanently damage your door.
- The Cost of Tools: Professional locksmithing requires more than just a Phillips-head screwdriver. If you are installing a new deadbolt, you may need to purchase hole saws, specialized chisels, and alignment jigs—tools that can easily cost more than the locksmith’s labor fee.
- Insurance Risks: Many Australian home insurance policies require exterior doors to be fitted with deadlocks that meet specific Australian Standards. If your house is burglarized and the insurance assessor determines the lock was installed incorrectly, your claim could be denied entirely.
The Locksmith Advantage: Doing it Right the First Time
While paying a professional involves an upfront labor cost, it provides immediate value that DIY simply cannot match. A professional locksmith ensures that the lock functions perfectly, aligns smoothly with the strike plate (preventing battery drain on smart locks), and provides maximum resistance against forced entry.
Furthermore, a professional can often save you money by repairing or rekeying an existing lock, rather than requiring you to buy a brand new one.
DIY vs. Professional Locksmith: A Cost & Risk Comparison
To help you decide which route is best for your specific situation, here is a breakdown comparing the two approaches:
| Factor | DIY Approach | Hiring a Professional Locksmith |
| Upfront Cost | Lower. You only pay retail price for the lock itself. | Higher. You pay for the lock, plus a call-out fee and professional labor. |
| Time Investment | High. Requires researching, driving to the store, buying tools, and spending hours trying to install it correctly. | Low. A professional can usually arrive quickly and complete a standard installation in under an hour. |
| Security Risk | High. Misaligned locks or incorrect strike plate installation make it incredibly easy for an intruder to kick the door open. | Zero. The hardware is installed to strict industry standards, ensuring maximum physical security. |
| Warranty & Guarantees | None on the labor. If you break the lock during installation, the manufacturer’s warranty is usually void. | Fully covered. Reputable locksmiths provide guarantees on both the high-quality hardware and their workmanship. |
| Best For… | Changing a simple internal bedroom door knob if you already have the tools. | Main entry doors, smart lock installations, commercial security, and emergency lockouts. |
When Should You NEVER DIY?
While you might get away with replacing a basic bathroom handle yourself, there are certain situations where DIY will almost always cost you more:
- Car Lockouts: Trying to use a coat hanger to unlock a modern car will likely scratch the paint, tear the weather stripping, and damage the internal window mechanisms—resulting in hundreds of dollars in repair bills.
- Home Emergencies: Breaking a window to get back into your house will always cost significantly more to fix than a locksmith’s emergency call-out fee.
- Master Key Systems: Businesses require precise, restricted key systems. DIY solutions cannot provide the necessary access control or legal key restriction.
