Trusted Lock Installation & Rekey for Katy Homeowners
Lock installation and rekeying in Katy typically costs $95-$285 per door depending on hardware grade, and most residential jobs are completed same-day with a single technician visit. For a detailed breakdown, see our Lock Installation & Rekey cost guide. Novak Lock & Security Katy has installed or serviced over 60,000 locks and key systems since 2002, every one starting with a written price and ending with a documented photo record left with the customer. We answer calls live at (832) 402-8386, 24 hours a day, and we do not use voicemail queues or callback windows.
Katy homeowners who bought between 2015 and 2025 often face a specific problem: their builder-grade Kwikset or Schlage locks are still original, the keys are unaccounted for from contractors and previous owners, and the hardware does not match the security profile of the neighborhood. In communities like Cinco Ranch, Pecan Grove, and Greatwood, we regularly find Grade 2 residential locks on front doors that should carry Grade 1 or high-security cylinders. We also provide our Lock Installation & Rekey in Richmond for homeowners in nearby areas seeking the same security upgrades. We replace what is there with what should be there, and we quote the full price on the phone before dispatching.
Our home base is in Katy, but we operate across the full west Houston corridor. Daniel Novak established the pricing rule in 2002 that still governs every call: the dispatcher quotes a firm price, and the technician is contractually prohibited from changing it at the door. Haven Standard Clause 1 is not a policy; it is a contractual obligation.
What Our Lock Installation & Rekey Service Includes
Smart Lock Installation
Smart locks connect to Wi-Fi or Bluetooth and allow keyless entry through a phone app, temporary access codes, or voice integration with systems like Alexa or Google Home. You need one when you want to eliminate key handoffs for housekeepers, dog walkers, or short-term rental guests, or when you simply do not want to carry a physical key. Novak Lock & Security Katy installs Yale Assure, Schlage Encode, and Baldwin Estate smart locks with factory-authorized procedures, and we document the network pairing and owner account setup in the photo record we leave with you.

Keyless Entry
Keyless entry systems use a fob, card, or proximity sensor rather than a traditional key or keypad code. You need this for side doors, pool gates, or detached garages where you want access without pulling out a phone or remembering a number. We install keyless entry hardware from Sargent and Schlage with commercial-grade latches, and we program all fobs on-site so you leave with every credential tested and working.

Keypad Lock
Keypad locks use a numeric code entered on a physical or touchscreen pad, with no app or phone required. You need one for children who do not carry phones, for elderly family members who prefer simplicity, or for rental properties where you want to change codes between tenants without rekeying. We install and program keypad locks from Schlage, Yale, and Baldwin, and we record the master code and all user codes in your written job documentation.

Biometric Lock
Biometric locks use fingerprint recognition to grant access, with no code or key to lose or share. You need one when you want absolute accountability about who enters, or when you manage a home office or gun room that requires restricted access. We install fingerprint-capable locks from select manufacturers and we calibrate the sensor sensitivity on-site to account for Texas humidity and temperature swings that can affect read accuracy.

Electronic Lock
Electronic locks encompass any lock powered by electricity or battery, including magnetic locks, electric strikes, and automated deadbolts. You need these for integrated security systems, for doors that must lock automatically on a schedule, or for compliance with insurance requirements on commercial spaces operated from a residential address. We wire and program electronic locks with proper voltage testing, and we leave you with the power supply specifications and battery replacement schedule in writing.

Key Duplication
Key duplication creates working copies from an existing key using precision cutting machines calibrated to manufacturer specifications. You need this when you have exhausted your spare set, when a new household member or employee needs access, or when you want to test whether a worn key is the problem before replacing the lock. We duplicate standard keys, high-security keys with restricted blanks, and Medeco, Mul-T-Lock, and Abloy keys that require factory-authorized equipment and credential verification.

Brands We Service for Lock Installation & Rekey

We are factory-authorized for Mul-T-Lock and stock their interactive and MT5+ cylinders, which use pin-in-pin technology that resists picking, bumping, and unauthorized duplication. We have installed hundreds of Mul-T-Lock units in Katy homes, particularly in gated communities where homeowners want key control without replacing the entire lock body. We also service and install Baldwin Estate and Reserve series hardware, which we frequently encounter in the custom builds of Cinco Ranch and Seven Meadows; we stock Baldwin’s mortise and tubular latch components and can match existing finishes from satin nickel to oil-rubbed bronze.
Yale smart locks are another core specialty, especially the Assure Lock SL and Lever models that integrate with August and Z-Wave home automation systems. We have diagnosed and resolved pairing failures that stem from router configuration issues in newer Katy subdivisions with mesh network installations. Sargent commercial-grade hardware appears regularly on home offices and accessory dwelling units in Pecan Grove and Mission Bend; we service their 10-line bored locks and 8200 mortise series with OEM parts. Whether you have Baldwin, Yale, Mul-T-Lock, Sargent, or any other make, we can source parts, diagnose failures, and install replacements with a written price before any work starts.
Before
AfterSigns You Need Lock Installation & Rekey Right Now
- Your keys are unaccounted for after a move, renovation, or relationship change. In Katy, we regularly find that new homeowners have no chain of custody for keys held by builders, painters, cleaning crews, or previous owners. Rekeying costs a fraction of full replacement and restores key control immediately.
- The lock cylinder turns loosely or the key sticks at certain angles. This indicates internal pin wear or corrosion, common in Katy after humid summers and occasional flooding events. A sticking cylinder will eventually fail closed or fail open, and either failure is avoidable.
- You have had a break-in or attempted break-in anywhere in your neighborhood. We rekey and upgrade locks for homeowners in Richmond, Rosenberg, and Jersey Village after nearby incidents, often installing high-security cylinders that resist the picking and bumping techniques used in residential burglaries.
- Your locks are more than 10 years old and builder-grade. Builder hardware in Katy homes from 2005-2015 is typically Grade 2 or lower, with brass-plated zinc bodies that corrode. We replace these with Grade 1 or high-security hardware that meets the actual security demands of the property.
- You need different keys for different doors and want a single key to work throughout the house. We can rekey multiple locks to a single keyway during the same visit, provided the hardware is compatible. This is common for homeowners in Four Corners and Greatwood who are simplifying access for aging parents or growing families.
Our Lock Installation & Rekey Process - Step by Step

- 1
Call and receive a written price before dispatch. When you call (832) 402-8386, a live person answers. You describe the door, the lock, and what you need. We quote a firm price range based on hardware grade and labor time. Haven Standard Clause 1 prohibits the technician from changing that price at the door, with no exceptions.
- 2
Technician arrival with background-checked identification and uniform. Our technician arrives in a marked van, presents identification, and confirms the written scope before touching any hardware. Every technician is background-checked and works to The Haven Standard documentation framework.
- 3
On-site diagnosis and confirmation of scope. The technician inspects the existing lock, door prep, and frame condition. If the scope changes due to hidden damage or incompatible hardware, we stop and call the office for a revised written price. You approve it before work continues.
- 4
Installation or rekeying with calibrated tools and OEM parts. For rekeys, we use pinning kits calibrated to manufacturer specifications. For installations, we use door prep templates and mortising tools that match the lock body’s exact dimensions. We do not force hardware into undersized bore holes or cover gaps with escutcheon plates.
- 5
Testing, documentation, and photo record delivery. Every lock is tested with every key, every code, or every credential before the technician leaves. We take a documented photo record of the completed work and leave a copy with you, along with the written warranty and the final invoice matching the quoted price.
How Much Does Lock Installation & Rekey Cost in Katy?
A typical residential rekey in Katy runs $95-$145 per cylinder, which covers removing the lock, repinning the cylinder to a new key, reinstalling, and testing. A standard lock installation with Grade 2 hardware runs $165-$245 per door, including the lockset, labor, and warranty. Smart lock installation with Wi-Fi configuration runs $225-$385 depending on network complexity and whether door prep modifications are needed. High-security cylinder installation with Mul-T-Lock or Medeco hardware runs $285-$475 per door, reflecting the restricted keyway and drill-resistant components.
| Service | Typical Range in Katy | What Affects Price |
|---|---|---|
| Residential rekey (per cylinder) | $95-$145 | Number of pins, cylinder type, after-hours call |
| Standard lock installation (Grade 2) | $165-$245 | Door prep condition, hardware brand, finish matching |
| Smart lock installation | $225-$385 | Network setup, app integration, door modifications |
| High-security lock installation | $285-$475 | Cylinder grade, restricted keyway, key registration |
| Key duplication (standard) | $4-$12 | Blank type, quantity, high-security authorization |
What affects the price: door thickness and bore hole diameter, whether the existing lock is a standard tubular or a mortise configuration, the need for strike plate adjustment, and whether you want all locks keyed alike. We do not charge a separate “trip fee” or “service call” surcharge. The price we quote on the phone is the price on the invoice. To avoid overpaying, get any competitor’s estimate in writing and bring it to us for a free second opinion. We will review it line by line and tell you whether the scope and hardware match what you actually need.
Our free estimate includes a phone consultation, a written price quote, and no obligation to schedule. If you proceed, the full price is confirmed again before the technician begins work.

Frequently Asked Questions - Lock Installation & Rekey in Katy

Lock installation replaces the entire lock body, strike plate, and hardware on a door. Rekeying changes the internal pin configuration of the existing cylinder so that old keys no longer work, without replacing the lock body. Novak Lock & Security Katy performs both services with a written price before any work starts, and we recommend rekeying when the hardware is sound but key control has been lost.
A standard residential rekey takes 20-30 minutes per lock. A full lock installation takes 45-75 minutes per door depending on door prep condition and whether modifications are needed. Smart lock installations with network pairing take 60-90 minutes. We schedule appointments with arrival windows, not all-day waits, and we call 15 minutes before arrival. Call (832) 402-8386 for availability and a firm time estimate.
