Lock Change in Marietta, GA
Our Residential Locksmith services make replacing the locks on your Marietta home a direct security upgrade. A standard lock change service at Novak Lock & Security Marietta typically costs $120-$280, depending on the hardware grade and the number of cylinders involved, with every price quoted in writing before we turn a single screw. If you have recently moved, lost a set of keys, or discovered that your current hardware is malfunctioning, we provide immediate, documented lock replacement services across Marietta, from the historic homes near the Marietta Square to the newer developments in East Cobb.
When you call us for a lock change, you aren’t getting a vague estimate or a technician who will change the price once they arrive at your door. We operate under Haven Standard Clause 1: the price quoted by our dispatcher is the price on your final invoice. Every lock change we perform includes a documented photo record of the work, ensuring you have a clear history of your home security.

When You Need a Lock Change
Not every security issue requires a full lock change, but there are specific moments when replacing the hardware is the only way to restore your home’s integrity. We often see Marietta homeowners requesting this service for the following reasons:
- Moving into a new home: You have no way of knowing how many copies of your house keys are currently in circulation with previous owners, contractors, or neighbors. Replacing the cylinders ensures you are the only one with access.
- Lost or stolen keys: If your keys were lost in a public place like the Marietta Square or a local park, the security of your home is compromised. We recommend a full hardware change rather than just a rekey if the keys were lost along with identification.
- Worn-out or damaged hardware: Older locks, particularly those exposed to the humidity and temperature swings common in Georgia, can begin to stick or jam. If your key drags or the latch doesn’t retract smoothly, the internal pins are likely damaged.
- Security upgrades: Transitioning from entry-grade hardware like basic Kwikset or Yale knobs to high-security systems like Medeco or Mul-T-Lock significantly reduces the risk of picking, bumping, or drilling.
- Break-in attempts: If a lock was damaged during an attempted entry, the structural integrity of the door frame and the bolt itself may be compromised. We replace the hardware to restore the door’s ability to resist force.
If you aren’t sure if you need a full replacement or a Lock Rekey, call (762) 252-5919 for an honest assessment. We provide a free second opinion on any written estimate you have received from another provider.
Our Lock Change Process
We believe in transparency. When you schedule a lock change with Novak Lock & Security Marietta, you can expect a standardized, professional experience that complies with The Haven Standard. Here is how we handle your security needs:
- Initial Consultation: You call our office, and a live person answers. We discuss the specific issues you are facing, identify the current brand of your hardware, and provide a firm, written price quote for the labor and materials.
- Arrival and Verification: Our technician arrives in a marked, professional vehicle. Before starting, they will confirm the scope of work and present the written quote for your approval.
- Hardware Removal: We carefully remove the existing hardware, inspecting the door prep and strike plate alignment to ensure the new lock will function correctly.
- Professional Installation: We install your chosen hardware-whether it is a standard Baldwin deadbolt or a high-security cylinder-ensuring the latch throws properly and the key turns without resistance.
- Documentation and Testing: Once installed, we test the operation of the lock multiple times. We then create a documented photo record of the installation, which is left with you as part of our commitment to transparency.
Safety Note: High-tension door mechanisms and electronic smart locks can be complex. If you are dealing with a heavy-duty commercial door closer or a high-security electronic system, we strongly recommend having a trained professional handle the installation to prevent injury or damage to the door frame.
Lock Change Pricing in Marietta
We do not use “starting at” pricing designed to get us in the door so we can upsell you later. Our pricing is fixed, transparent, and provided before we arrive. Below is a breakdown of How Much Does Residential Locksmith Cost? (2026 Price Guide) - Marietta, GA when budgeting for a lock change in the Marietta area.

FAQs - Lock Change
Is it cheaper to repair a lock or replace it entirely?
If the internal components of a lock are worn-such as the pins or the cam-replacing the hardware is almost always the more cost-effective choice in the long run. Repairs are often temporary, whereas a new lock provides a fresh mechanical lifespan and the benefit of a new warranty. Call (762) 252-5919 for an exact quote so you can compare the cost of repair versus replacement before you decide.
Can you match my new locks to my existing keys?
Yes, we can perform a “keying” service where we match new cylinders to an existing key, provided the locks are of the same brand and keyway. This allows you to have a single key for your front door, back door, and garage entry. If you are mixing brands, this may not be possible, and we will explain why during our initial consultation.
How long does a typical lock change take?
A standard lock change usually takes between 30 and 60 minutes for a single door. If we are replacing multiple doors or installing high-security hardware that requires modifications to the door prep, the time may increase. We provide an estimated duration when we give you your firm price quote.
Do you offer a warranty on lock changes?
Every service we perform is backed by our 365-Day Done Right Promise. If the hardware we installed fails or if the installation does not function as intended within one year, we will make it right at no additional cost to you. This is part of our commitment to the quality standards we uphold at our home office.
