Lock Change in Phoenix, AZ
A standard lock change in Phoenix, AZ, typically costs between $120 and $280 per door, depending on the hardware grade and the complexity of the existing door prep.

At Novak Lock & Security, we understand that a lock change is rarely just about hardware. It is about restoring the security of your home. Whether you have moved into a new property, lost your keys, or are dealing with hardware that has failed due to the intense Phoenix heat, we provide a consistent, documented service. We are a locally operated business, not a call center, and every technician we send is background-checked and uniformed. We work across the entire Phoenix metro area, providing services that fall under our home page services and our specialized Residential Locksmith in Phoenix division.
When You Need Lock Change
You may not always need a full lock change when you have a security concern. Sometimes, a Lock Rekey is sufficient. However, there are specific situations where installing new hardware is the correct choice to ensure your home remains secure. We see these scenarios regularly in neighborhoods ranging from Arcadia to Desert Ridge.
- Moving into a new home: You have no way of knowing how many copies of your keys are in circulation from previous owners, contractors, or neighbors. Replacing the hardware gives you a clean slate.
- Hardware failure due to heat: The extreme Phoenix sun causes metal expansion and contraction, which can warp internal springs and deadbolt mechanisms over time. If your key feels gritty or the bolt is difficult to throw, the internal components are likely failing.
- Security upgrades: If your current locks are entry-grade, they may be vulnerable to bumping or picking. We often install higher-grade hardware from manufacturers like Schlage, Sargent, or Abloy for customers who want to move from standard security to high-security protection.
- Lost or stolen keys: If you have lost your only set of keys, replacing the lock cylinder or the entire lock assembly is often the most cost-effective way to ensure unauthorized access is impossible.
- Broken keys inside the cylinder: If a key has snapped off inside your lock, we can often extract it. However, the extraction process can sometimes damage the cylinder pins, making a full lock change the more reliable, long-term solution.
Our Lock Change Process

We operate under The Haven Standard, a framework designed to ensure that every customer receives the same level of service, documentation, and technical accuracy. We do not believe in surprises or price changes once we arrive at your door.
- The Initial Quote: When you call (480) 376-7170, our dispatcher will ask for photos of your existing hardware or a description of your door. We provide a firm, written price range based on that information. Clause 1 of The Haven Standard states that the price on the phone is the price on the invoice.
- The Arrival: Our technician arrives in a marked, stocked vehicle. They are uniformed and background-checked. Before any work begins, they will inspect the door frame and the current lock to ensure the new hardware will fit properly without requiring structural modifications to your door.
- The Installation: We install the new lock, ensuring the strike plate is aligned and the deadbolt throws smoothly. We use professional-grade tools to ensure the finish is not scratched and the door is not damaged.
- The Documentation: We provide a documented photo record of the completed job. This includes a photo of the new lock installed and a written scope of the work performed. This serves as your receipt and your record of the security upgrade.
- The 365-Day Done Right Promise: We stand behind our work. If the lock fails or was not installed correctly, we will make it right at no cost to you for up to 365 days.

FAQs - Lock Change

Is it cheaper to repair or replace a lock?
If the lock is a high-quality model and the issue is minor, such as a sticky keyway that needs lubrication or a loose screw, a repair or a rekey is usually the most cost-effective solution. However, if the internal springs are worn out or the metal is fatigued, a repair is only a temporary fix. Replacing the lock is often the better value in the long run because it provides a fresh 365-Day Done Right Promise on the entire assembly.
Can you change my locks the same day I call?
Yes, we offer same-day service for most residential lock changes in Phoenix, including Residential Lockout emergencies. Because we carry a wide inventory of hardware in our vehicles, we can typically complete the installation in a single visit. Call (480) 376-7170 to check our current schedule and technician availability.
Do you work with high-security brands like Mul-T-Lock or Abloy?
Yes, we are experienced with the full security spectrum, from entry-grade hardware to high-security cylinders that are pick-resistant and bump-resistant. We can install systems from manufacturers like Mul-T-Lock, Abloy, Sargent, and Schlage. We will discuss your security goals when you call to ensure we provide the right level of protection for your property.
What if the new lock doesn’t fit my door?
This is why we ask for photos or descriptions before we arrive. In the rare event that your door prep is non-standard or incompatible with the hardware you selected, we will communicate this before we begin any work. We are trained to modify door preps, but we will always provide a written quote for any additional labor required before we turn a single screw. You will never be surprised by an invoice.
Safety Note: If you are attempting to work on high-tension components or integrated smart-lock systems, please exercise caution. Improper installation of a deadbolt can leave your home vulnerable to intrusion or prevent you from exiting in an emergency. If you are unsure about the mechanical requirements of your door, contact a professional to ensure the work is done to code.
