How Much Does Lock Installation & Rekey Cost in Chicago?

Lock rekeying in Chicago typically costs between $85 and $130 per cylinder, while installing a new deadbolt ranges from $120 to $250 plus the cost of the hardware. At Novak Lock & Security, we provide a firm, written price before any work begins for our Lock Installation & Rekey services, adhering to our founding rule that the quote delivered by our dispatcher is the exact price you pay on-site. We serve all Chicago neighborhoods, from the historic brownstones in Lincoln Park to modern high-rises in the Loop, ensuring your property is secured according to your specific needs.

Lock Installation & Rekey Cost Breakdown (2026)

Pricing for locksmith services in Chicago is determined by the complexity of the hardware and the time required to ensure the mechanism functions correctly. We do not use “starting at” pricing that balloons once the technician arrives. When you call (331) 202-1318, we provide the total cost for the labor and service.

These figures represent the labor and service costs for professional locksmithing in the Chicago market. If you are replacing hardware, the final invoice will include the cost of the specific lock brand you select, such as Schlage, Baldwin, or high-security options like Abloy. Every installation we perform is backed by our 365-Day Done Right Promise. If the lock does not function perfectly, we return to make it right.

What Affects Lock Installation & Rekey Pricing in Chicago

Several factors influence the final cost of your locksmith service. Understanding these variables helps you know what to expect when a technician arrives at your property.

• Hardware Complexity: Installing a standard residential deadbolt is a straightforward process, but installing high-security cylinders from brands like Medeco or Mul-T-Lock requires precision drilling and calibration. These locks are designed to be pick-resistant and bump-proof, which adds to the installation time and technical requirements.
• Door Material and Condition: Chicago homes vary from historic wood-frame structures to modern steel-reinforced doors. If your door is misaligned due to the city’s seasonal temperature shifts, a simple lock install may require additional adjustments to the strike plate or door frame to ensure the bolt extends fully. We do not force locks into misaligned doors; we adjust the door to fit the lock.
• Lock Type: A standard cylindrical lock, common in suburban-style builds, is cheaper to service than a mortise lock. Mortise locks are frequently found in older Chicago buildings and require a deep pocket in the door edge. Servicing these requires a technician with specific experience in antique hardware, which increases the labor cost.
• Master Key Systems: If you are managing a multi-unit building and require a master key system-where one key opens the common area and your unit, but tenants only have keys to their own doors-the labor costs increase due to the complexity of the pinning process.
• Emergency vs. Scheduled Service: We provide 24/7 service, but dispatching a technician outside of standard business hours for an emergency lockout or a security-critical failure involves different operational costs than a scheduled installation during the day.

Daniel Novak, the owner of Novak Lock & Security, ensures that all our technicians are background-checked and uniformed. When we arrive, we do not guess at the price. We assess the hardware, explain the security gap, and provide a written price before turning a single screw.

How to Save on Lock Installation & Rekey

The most effective way to manage your security budget is to avoid the “cheap” call-out services that use bait-and-switch tactics. A low price quoted over the phone often hides significant upcharges once the technician is at your door. You can save money by being prepared.

• Consolidate Services: If you need multiple locks rekeyed or installed, have them done in one visit. We charge for the trip and the labor, so addressing three doors at once is more cost-effective than scheduling three separate visits across different weeks.
• Provide Photos: When you call (331) 202-1318, describe your lock or text us a photo. If we know exactly what hardware you have, we can provide an accurate quote over the phone. This prevents surprises and ensures our technician brings the correct tools and parts for the job.
• Choose the Right Grade: You do not always need the most expensive high-security lock for every entry point. We can help you identify which doors are high-risk and which are standard, allowing you to allocate your budget effectively.
• Avoid DIY Mistakes: Attempting to install a high-security lock without the proper template or tools often leads to a damaged door or a lock that does not engage properly. Fixing a botched installation is significantly more expensive than paying a professional to do it correctly the first time.

Our commitment to you is simple: we provide a free second opinion on any written estimate you have received from another company. If you are unsure about a quote, bring it to us. We will review it at no charge.

The Haven Standard: Our Documentation Process

At Novak Lock & Security, we operate under The Haven Standard. This is a quality and documentation framework that governs every job we perform. When you hire us for Lock Installation & Rekey in Chicago, you are not just getting a new key or a new cylinder.

Every visit includes a documented photo record of the lock before and after we finish the work. We provide this to you at the end of the job. This record proves that the work was performed to the agreed-upon specifications. Whether we are installing a standard Schlage deadbolt or a high-security Abloy system, the documentation ensures you have a permanent record of your security status. This is standard procedure for every customer, regardless of the job size.

FAQs - Lock Installation & Rekey Cost

How much does it cost to rekey a lock in Chicago?

Rekeying a standard residential lock typically costs between $85 and $130 per cylinder, assuming the lock is in good working condition. The process involves changing the internal pins so that the old keys no longer work, and we provide you with a new set of keys. Call (331) 202-1318 to get a firm quote for your specific lock type.

Is it cheaper to replace a lock or rekey it?

Rekeying is almost always cheaper than replacing a lock, costing roughly 40% to 60% less than a full hardware replacement. You should rekey if your existing hardware is high-quality and functions smoothly; you should replace if the lock is damaged, outdated, or you want to upgrade to a higher security grade.

Can you fix a lock that is stuck or won’t turn?

Yes, we can repair stuck locks, and the cost usually ranges from $120 to $200 depending on whether the issue is internal debris, a bent key, or a misaligned door frame. We always assess the hardware first to see if a repair is viable or if the lock’s internal mechanism has failed, which would require a replacement.

Do you offer 24/7 emergency service?

We provide 24/7 service, and our calls are answered by a live person at any hour of the day or night. Emergency service pricing varies based on the time and the specific security issue, but we always provide the cost in writing before we begin work, adhering to our no-hassle pricing policy.

What brands do you service?

We service and install the full spectrum of lock brands, from entry-grade Kwikset and Schlage to high-security systems like Medeco, Mul-T-Lock, and Abloy. If you have a specific brand in mind for your home, let our dispatcher know when you call, and we will confirm availability and pricing immediately.

Safety and Security Warning

Security hardware, particularly deadbolts and high-security cylinders, involves critical components that must be installed with precision. Improper installation can result in a lock that fails to engage, leaving your property vulnerable, or a lock that jams and prevents you from exiting during an emergency. If you are dealing with high-tension springs or complex high-security cylinders, we strongly recommend hiring a trained professional. Do not attempt to drill into your door or modify the strike plate without the correct templates and tools, as permanent damage to your door or frame is often irreversible. If you are unsure about the state of your security, call (331) 202-1318 for a professional assessment.
