Fast, Reliable Lock Installation & Rekey Across Rockville
Lock installation and rekey work in Rockville typically runs $95-$220 for a standard cylinder rekey and $180-$475 for a new deadbolt installed by a licensed locksmith. Most jobs are completed same-day, and our crews carry hardware for everything from a 1950s Twinbrook Cape Cod to a King Farm smart-lock upgrade. If you’ve bought a home, lost a key, or just want every exterior door working off a single key, this page explains exactly how we handle it. Call (331) 310-8471 and get a written price before anyone rolls a truck.
We know Rockville’s housing stock the way a good mechanic knows a specific engine. The original Twinbrook ramblers and Cape Cods settle, the door frames shift, and a deadbolt that worked fine in September jams by February. Newer construction off Rockville Pike has its own issues, mostly around electronic access and smart-lock retrofits. We’re a full-service Lock Installation & Rekey shop serving all of Rockville, and the price you’re quoted on the phone is the price on the invoice. That rule has been in place since Daniel Novak started this company in 2002.
Why Novak Lock & Security Is Rockville’s Preferred Lock Installation & Rekey Company
Novak Lock & Security has been installing locks, rekeying cylinders, and cutting keys since 2002, with over 60,000 locks, keys, and systems serviced since then. Every one of those jobs started with a written price and ended with a documented record. In Rockville, our technicians are background-checked and uniformed, and every visit includes a photo record of the work, left with you before we leave. That is Haven Standard procedure, and it’s never been an upsell.
Our dispatchers answer the phone live, 24/7. No voicemail queue, no callback window. If you’re locked out of a deadbolt that refuses to throw on a February morning in Twinbrook, you get a real person who can dispatch a Rockville-area tech, not a recording. Our response time to most Rockville neighborhoods runs 30 to 45 minutes for emergency calls. We’re independent, locally operated under The Haven Standard, and led by Daniel Novak. No franchise script, no “technician will call you back within the hour” delay.
Rockville homeowners are decisive about security. The NRC campus in White Flint and the federal contractor community throughout the Rockville and Bethesda corridor mean a lot of our customers already understand physical security at a professional level. They want branded hardware with spec sheets, not vague reassurances. We stock Baldwin, Schlage, Yale, Mul-T-Lock, and Sargent cylinders and hardware in our Rockville service vehicles, so most rekeys and installs are done in one visit, not one visit plus a parts order.
Our Lock Installation & Rekey Services in Rockville
Smart Lock Installation
Smart lock installation in Rockville runs $150-$390 including hardware integration and app setup, depending on whether you’re retrofitting an existing deadbolt or installing a full keypad-and-handle assembly. We install Yale Assure, Schlage Encode, and keypad models that integrate with Ring, Google, and Apple Home. For Rockville townhouses and condos off Rockville Pike, we check door thickness and bolt alignment before ordering hardware, because a six-year-old building settles less than a sixty-year-old one, but it still moves.
Keyless Entry and Keypad Locks
Keyless entry installation in Rockville runs $180-$320 per door for a mechanical or electronic keypad deadbolt, including programming and a printed user guide for every household member. These are the most requested upgrade in King Farm and the Rockville Town Center corridor, where kids walk home from Richard Montgomery or the bus stop and fumbling for keys becomes a daily irritation. We program unique codes per family member, show you how to disable a code remotely, and verify the deadbolt throws cleanly before we leave.
Biometric Lock Systems
Biometric lock installation in Rockville runs $300-$650 for residential fingerprint or app-based access systems, with commercial-grade biometric readers from Sargent and other manufacturers priced by site scope. These systems are popular among Rockville’s federal and defense-sector families who want a lock that cannot be picked, bumped, or shared. We’ll assess your door frame and power options first. A biometric reader on a sagging 1958 frame is a bad investment until the frame is reinforced, and we’ll tell you that plainly.
Key Duplication
Key duplication in Rockville runs $3-$8 for standard residential keys and $15-$45 for restricted or high-security blanks like Medeco or Mul-T-Lock, cut on site from your existing key or from a code. We cut bump-resistant keys for homes in Twinbrook and East Rockville where lock bumping is a known entry method among criminals. If you need six copies of a Mul-T-Lock key, we verify the keyway and card before cutting, because high-security blanks are serialized and not interchangeable with the hardware-store version.

Trusted Brands We Service in Rockville
We’re factory-authorized on Medeco, Mul-T-Lock, Baldwin, Schlage, and Yale, and we stock cylinders, deadbolts, and keypad assemblies for those brands in our Rockville service vehicles. That means a Baldwin mortise lock on a Woodley Gardens colonial or a Schlage deadbolt on a Twinbrook rambler gets original manufacturer parts, not aftermarket substitutes. For high-security work near White Flint and the NRC-adjacent neighborhoods, we can install Mu-T-Lock or Medeco cylinders the same day, with all keys on a controlled system that requires a signed key card for duplicates. You see the key card, the lock spec sheet, and the price in writing before the first screw comes out.
Common Lock Installation & Rekey Problems We See in Rockville Homes
- Deadbolt-to-strike-plate misalignment in Twinbrook. Homes built between roughly 1951 and 1965 settle unevenly. The door drifts, the bolt drags, and a deadbolt that turns smoothly in July will not extend at all by late January. A rekey alone does not fix this. The fix is plate realignment or a frame reinforcement kit, and we handle it in the same visit.
- Soft, thin jamb wood on original Cape Cods and ramblers. The original jamb stock was thinner than today’s ANSI standard, and six decades of freeze-thaw cycling through Rockville winters has softened some of it to the point where a new deadbolt cannot pass a basic kick-in test. We carry Grade-2 reinforcement kits and install them before we even think about rekeying the lock above it.
- Multiple keyways across one property. Rockville has an unusually high number of acreage properties and older homes with separate workshops, carriage-house garages, or gate locks, each possibly keyed to a different keyway. You cannot master-key a Kwikset and a Schlage to the same key without changing cylinders. We source replacement cylinders in the correct keyway and key every door and outbuilding alike in a single visit, provided the hardware allows.
- Electronic lock upgrades on older Rockville frames. A smart deadbolt has tighter bolt tolerances than a 1950s mechanical lock ever had. If the door has settled and the bolt throws with friction, the motor will burn out early or the lock will jam. We check the frame before we install, and we’ll tell you if you need a reinforcement before the smart lock goes in.
In Twinbrook, we recently rekeyed a Cape Cod after the owner lost tenant keys and wanted everything keyed alike-front, side, and the detached workshop. Our tech first corrected a severe deadbolt-to-strike-plate misalignment from decades of slab settling, then installed a Grade-2 deadbolt reinforcement kit because the 1950s jamb wood had softened enough to fail a basic kick-in test. We finished by cutting four new bump-resistant keys from one master, leaving every door and the workshop on a single key. One visit, one key, one documented photo record.

FAQs - Lock Installation & Rekey in Rockville
In most cases, yes. We rekey the existing mortise cylinder to a new key, then rekey or replace the door and workshop locks to that same key, provided the cylinder housings are in serviceable condition. If the mortise lock body is worn beyond reliable operation, we’ll tell you and quote a replacement cylinder or lock body separately. Call (331) 310-8471 for an exact quote; estimates are free and binding.
No. The problem in Twinbrook is almost always a settled door frame from decades of slab movement, compounded by Rockville’s freeze-thaw cycles. A rekey changes the pins inside the cylinder; it does nothing to the frame. The fix is plate realignment or a frame reinforcement kit, and we handle both. Call us and we’ll assess it on site and give you a written number before any work starts.
Yes. We install a keypad smart lock on the main entry and a mechanical deadbolt or mortise cylinder on the side gate, then key both to the same physical key. You get code entry at the front door and a single key that works the gate and the mechanical override on the smart lock. Call (331) 310-8471 and we’ll spec it out over the phone.
Many of our White Flint and NRC-adjacent customers do choose high-security cylinders, and we stock Medeco and Mul-T-Lock for same-day installation. These cylinders resist picking, bumping, and unauthorized key duplication through a controlled key-card system. If you work with classified material or just want a lock that cannot be copied at the hardware store, ask us about a high-security rekey. We’ll quote it in writing before we start.
Yes, as long as the hardware allows it. We schedule one appointment, bring cylinders and hardware for the keyway you have or the one you want, and key every door, outbuilding, and gate alike in one visit. If a lock is too far gone to rekey, we’ll replace it with a matching cylinder and finish the job the same day. Call (331) 310-8471 for a written quote. The word “price” has a real meaning here, and we honor it.
