Fast, Reliable Lock Installation & Rekey Across Brookline
Lock rekey in Brookline typically runs $25-$45 per cylinder, quoted in writing before we start. Lock installation ranges from $95 for a standard entry knob or deadbolt to $450-$650 for a high-security mortise retrofit on an original pre-war door. If you live in a Coolidge Corner condo or an Aspinwall Hill Victorian, you already know the difference: generic cylindrical locks do not drop into 100-year-old mortise pockets without chewing through the millwork. Our Lock Installation & Rekey team works on Brookline’s original hardware every week. Call (331) 310-8471 and you’ll get a firm price on the phone, per Haven Standard Clause 1: the price on the phone is the price on the invoice.

Why Novak Lock & Security Is Brookline’s Preferred Lock Installation & Rekey Company
Brookline’s housing stock is older than almost anywhere else in Greater Boston. That matters because most of the lock work here is not “remove two screws and swap the knob.” It involves original mortise locksets from Corbin, Yale, and Russwin that were installed when Coolidge Corner’s brick apartment blocks went up in the 1910s and 1920s. We carry the specialized tools and replacement parts for these systems. We stock mortise cylinders in common Brookline door preps, and we know which legacy hardware can be rekeyed and which needs a full rebuild.
Daniel Novak founded this company in 2002 on a rule that still governs every job: the dispatcher quotes a firm price, and the technician is not permitted to change it at the door. That rule has held for 60,000+ locks, keys, and systems installed or serviced. It holds in Brookline. It holds everywhere. Background-checked, uniformed technicians work to The Haven Standard, and every visit ends with a documented photo record left with the customer. Not a promise. A procedure.
When a building association on Beacon Street needs a 32-unit master key system rekeyed, they need a locksmith who can inventory existing cylinders, cut new keys, and keep the street-level vestibule lock functioning for every resident. We do that work in Brookline on a regular basis. If you want a second opinion on any written estimate, bring it to us and we’ll review it at no charge.
Our Lock Installation & Rekey Services in Brookline
Smart Lock Installation
Most Brookline condo boards will not allow you to change the exterior hardware on a shared entry. What they will allow, in many units, is a smart lock on the interior unit door or a retrofit smart cylinder that works with the existing mortise body. We install smart locks on unit doors throughout Brookline, and we’ll tell you in advance whether your original frame can take the lock without modification. Expect $180-$350 for a standard smart deadbolt install, more if the existing mortise needs a conversion plate.
Keyless Entry & Keypad Lock
Keyless entry is practical in Brookline’s multi-tenant buildings because it eliminates the cost of rekeying every time a tenant turns over. A keypad deadbolt on a unit door runs $150-$280 installed, depending on whether we’re working with a standard cylindrical prep or adapting to an old mortise pocket. For building vestibules governed by a condo association, we recommend commercial-grade keypad systems with audit trails and per-user codes. Those start around $500 and require written board approval before we begin.
Biometric Lock
Biometric locks read a fingerprint and open without a key. They work well on interior unit doors in Brookline, particularly in buildings where residents have lost keys or where short-term rentals require frequent access changes. A residential biometric deadbolt runs $220-$400 installed. On original pre-war doors, the limiting factor is always the same: we have to see whether the door is thick enough and the frame is true enough for the lock to function reliably through a Boston winter. We’ll tell you before you buy anything.
Key Duplication
Brookline’s older locks often use restricted or unusual keyways. Big-box key machines cannot cut a Russwin mortise key or a warded skeleton key for a Victorian passage set. We can. We cut standard keys, high-security restricted keys (with proper authorization), and legacy keys for original Brookline hardware. Standard duplication runs $5-$12 per key; restricted or specialty keys run $15-$40. Bring the original and we’ll match it on the spot.

Trusted Brands We Service in Brookline
We service and install Baldwin, Mul-T-Lock, Sargent, and Abloy hardware across Brookline. Baldwin is common on the high-end single-families near Aspinwall Hill and Fisher Hill, where homeowners want period-appropriate brass and solid construction. Mul-T-Lock and Abloy are high-security cylinders that cannot be picked or bumped by standard tools; we are factory-authorized on both, and we install them frequently for Brookline condo boards after a break-in or a lost-key incident elevates the security requirements. We keep common mortise cylinders, strike plates, and tailpieces on the van so we aren’t running back to a supplier mid-job. The full price is quoted on the phone before anyone is dispatched, and that is the price on your invoice, with no call-out surcharge added on arrival.
Common Lock Installation & Rekey Problems We See in Brookline Homes
- Deadbolt jams every winter. Brookline’s 30-plus freeze-thaw cycles per year swell and rack the original door frames. The deadbolt throw no longer lines up with the strike plate. We realign the strike, adjust the bolt, and in severe cases refit the frame so the lock works through every season.
- Broken skeleton-key passage sets. Victorian triple-deckers across Brookline still have warded passage locks on hallway and pantry doors. When the worn mechanism shears internally, the door is locked and there is no modern cylinder to rekey. We rebuild the warded mechanism or install a discreet modern keyed lock without altering the period trim.
- Condo boards ordering the wrong retrofits. We regularly get called after someone’s handyman drilled out a 1920s mortise lock and left a rattling cylindrical knob in a chewed-out door. Rehabilitating that frame and restoring the mortise hardware costs more than doing it right the first time. We can often repair the damage and recondition the original lock.
- Lost keys in shared buildings. One lost unit key in a 20-40 unit Brookline building means the association faces a rekey decision. We inventory the master key hierarchy, identify which cylinders are compromised, and rekey only what’s necessary. You don’t have to rekey the entire building every time if the system was set up correctly.

FAQs - Lock Installation & Rekey in Brookline
Yes, in most cases it can be rekeyed. A mortise lock rekey in Brookline runs $25-$45 per cylinder if the lock body and internal components are intact. Replacement only becomes necessary when the internal springs, levers, or bolt are worn to the point of failure, which we see on some original 1920s hardware. We’ll open the lock, show you the condition of the internals, and give you a written recommendation either way. Call (331) 310-8471 to schedule, and the price you hear is the price on the invoice.
Your door frame is moving. Brookline’s 30-plus freeze-thaw cycles every winter cause the original wooden frames in pre-war buildings to swell and shift. The deadbolt throw no longer lines up with the strike plate, so the bolt binds instead of turning freely. The fix is usually a strike plate adjustment or a minor frame realignment, typically $75-$150, and it holds through the season. If your building has a maintenance staff, ask them to have us look at the full entry rather than just forcing the bolt.
Yes, without destroying the original trim. We install discreet modern keyed locksets or high-security deadbolts on Victorian passage doors around Coolidge Corner, Washington Square, and Aspinwall Hill while preserving the period escutcheons and millwork. In many cases we can rebuild the original warded mechanism and add a keyed rim lock above it for modern security. Expect $150-$350 per door depending on the hardware grade and the condition of the frame. Call (331) 310-8471 and we’ll give you a firm number before we send anyone out.
The association rekeys only the cylinders that are compromised, not the entire building, assuming the master key hierarchy is documented. We inventory the existing system, identify which cylinders the lost key operated, and rekey those cylinders while preserving the master key integrity for the rest of the building. In older Brookline buildings running original Russwin or Corbin mortise cylinders, that inventory step is essential. Rekeying a single compromised unit cylinder typically runs $25-$45; rekeying an entire building’s common areas and vestibule runs higher, and we’ll give the board a written scope and a flat per-lock price before anything is ordered.
Sometimes. A standard smart deadbolt fits a standard cylindrical prep, which many Brookline unit doors have. On original mortise hardware, we can often use a retrofit smart cylinder that keeps the original body and faceplate. The determining factors are door thickness, frame alignment, and the type of mortise body. We’ll evaluate your door and tell you which options are actually viable before you spend money on hardware. Smart lock installation in Brookline runs $180-$350, and the price includes testing through multiple open-close cycles so the lock works the first night, not just the first hour.
