Fast, Reliable Lock Installation & Rekey Across Jamaica Plain
Lock installation and rekey in Jamaica Plain usually means working with hardware that was installed before the Model T. Our Lock Installation & Rekey crews handle both sides of the trade here: modern smart locks and restricted key systems on the same doors that still carry century-old mortise locks. We schedule most Jamaica Plain jobs within one business day, and emergency calls are dispatched as soon as a technician frees up. Daniel Novak has run this company since 2002, and the rule from day one hasn’t moved: the price you get on the phone is the price on the invoice. Call (331) 310-8471 and you’ll speak to a live person, not a queue.
Why Novak Lock & Security Is Jamaica Plain’s Preferred Lock Installation & Rekey Company
Jamaica Plain has 1,300-plus triple-deckers still standing from the 1890-1925 building era. That’s the job site. Most of those buildings retain their original Corbin, Yale, or Sargent mortise locksets, and the average locksmith trained on modern cylindrical deadbolts doesn’t stock parts for them. We do. Daniel Novak keeps legacy mortise parts, skeleton-key blanks, and high-security cylinder kits on the trucks that serve Jamaica Plain because he knows the moment a Medeco retrofit lands on a Perkins St vestibule door, the tech needs to open the door without wrecking the stile.
Boston’s freeze-thaw cycle is the other reason this work needs local hands. Unheated triple-decker vestibules take in moisture all winter, and by February the cylinders ice up and the pins jam. Keys snap. We see it every January through March, and we stock the cylinders and graphite kits to fix it same-day. The crews carry a documented photo record for every visit: what the lock looked like when we arrived, what we replaced, and what it looks like when we leave. You get that record. It’s standard procedure, not an upgrade.
Our Lock Installation & Rekey Services in Jamaica Plain

Most Jamaica Plain lock work falls into one of four jobs. Here’s how we handle each in this neighborhood specifically, given what the housing stock actually looks like.
Smart Lock Installation
Smart locks on a JP triple-decker usually get retrofitted onto an existing mortise lock body, not a fresh cylindrical bore. That’s the distinction that separates a clean install from a botched one. We’ve fitted Yale Assure and Schlage Encode locks onto South St and Robinwood Ave doors where the original Sargent mortise below stays functional, so the skeleton key still works if the battery or the app doesn’t. The smart lock operates the deadbolt only, and the original keyway stays untouched unless you want it rekeyed too.
Keyless Entry
Shared vestibule entries in Jamaica Plain rental buildings are the main driver for keyless entry work. A three-unit building with eight tenants and a rotating cast of roommates needs a code, not a key ring that multiplies on every lease renewal. We install keypad systems on the vestibule door while keeping the interior unit doors on standard or restricted keys. That way the landlord controls one code, revoking it when a tenant leaves costs nothing, and the inner doors don’t need new hardware.
Keypad Lock
Keypad locks get the most use on single-family conversions around Jamaica Plain where the owner wants a deadbolt without carrying a key on runs around Jamaica Pond. Baldwin and Schlage keypads are the two we install most in this neighborhood, both wired into the existing door prep when the door allows it. On thick wood doors that won’t accept a standard backset, we rework the mortise pocket and keep the keypad as the entry layer, not the only layer.
Biometric Lock
Biometric locks on Jamaica Plain doors are a niche request, but a consistent one among owners who’ve done full condo conversions and want the building manager to have an audit trail. We install fingerprint and RFID readers that log every entry, which matters for condo associations that need a documented record of who entered the vestibule and when. The biometric cylinder is typically paired with a Mul-T-Lock or Medeco keyway so the physical key remains restricted even when the electronic side is off.
Trusted Brands We Service in Jamaica Plain
We service and install Yale, Baldwin, Mul-T-Lock, and Sargent hardware across Jamaica Plain, and we stock the legacy parts those brands no longer ship to retail. For triple-deckers, that’s the difference between a one-day rekey and a week of waiting on a distributor. High-security jobs in JP usually mean Mul-T-Lock or Medeco restricted keyways that can’t be duplicated at a Centre Street kiosk, and we order those cylinders ahead of the install date so the work itself runs one visit. Every brand we recommend gets a written scope and a flat per-lock price before anything is ordered.
Common Lock Installation & Rekey Problems We See in Jamaica Plain Homes

- Iced-up vestibule cylinders from freeze-thaw moisture. Unheated triple-decker entries along Centre Street and the side streets collect condensation all winter. The pins corrode, the key binds, and by mid-January keys break off inside locks. We replace the cylinder and re-lubricate with graphite, which doesn’t freeze the way petroleum sprays do.
- Restricted keys copied at a local kiosk. Mul-T-Lock and Medeco restricted keys won’t cut properly on retail machines, and a bad copy jammed into the cylinder is a common call in Jamaica Plain. We extract the broken blank and, if the cylinder is damaged, rekey the lock to keep the keyway true.
- Condo conversion master key failures. When a triple-decker converts to condos, the new association often discovers the old rekey didn’t cover every unit. The building manager’s override won’t turn in one or two locks, and the whole system needs rehashing. We rebuild the master system from the cylinder up rather than patching it.
- Mortise lock wear on original wood doors. Heavy wood door stiles on South St and Perkins St buildings put a lot of torque on old mortise lock bodies. The spindles wear, the latch retraction gets sloppy, and the lock eventually stops catching. We rebuild the mechanism in place rather than replacing a door that’s been there for a century.
Pricing for Lock Installation & Rekey in Jamaica Plain, MA
Lock rekey in Jamaica Plain typically runs $25-$45 per cylinder, quoted in writing before we start. Rebuilding a century-old Corbin mortise lock usually lands between $80 and $150 in labor depending on how much of the internal mechanism needs replacement. Smart lock installation runs $150-$300 in labor on top of the hardware cost, and a full keypad entry system for a shared vestibule typically falls between $450 and $800 including parts and installation. Restricted keyway systems (Medeco or Mul-T-Lock) start around $35 per keyed cylinder plus a one-time system setup of $150-$300 depending on the number of units.

FAQs - Lock Installation & Rekey in Jamaica Plain

Yes. We do this routinely on Jamaica Plain triple-deckers. The original Corbin or Sargent mortise body stays in the door, and we pull the old cylinder out and install a new Medeco or Mul-T-Lock restricted cylinder in the same mortise pocket. The keyway becomes restricted, the key can’t be duplicated at a kiosk, and the antique hardware stays untouched. Call (331) 310-8471 for a written quote on your specific lock set.
We remove the cylinder through the faceplate, not the door edge, and extract the existing pins with the lock body still mortised in place. The wood stile never gets cut or drilled. On South St and Perkins St doors, that means the original wood stays intact and the mortise pocket remains true for the next rekey. We’ve rebuilt enough of these locks that the process is routine and the door doesn’t get scarred.
Yes, but it requires routing additional mortise pockets and installing top and bottom shoot bolts that throw with the central lock. Heavy wood doors on Jamaica Plain triple-deckers are actually good candidates because the stiles are thick enough to take the hardware. We’ve done these conversions on Robinwood Ave and Perkins St buildings, and the work is quoted flat per door ahead of time.
Install a keypad smart lock as the primary entry mechanism and keep the original mortise lock in the door as a mechanical backup. The smart lock handles day-to-day entry, the code gets changed between tenants, and the skeleton-key mortise below it stays intact. If the keypad battery dies, the old key still works. That’s the setup we install most often in Jamaica Plain vestibules.
Yes. A master key system gives each unit owner a key that opens only their unit, while the building manager’s key opens all units plus the vestibule. We custom-pin the new restricted keyways on-site, so the condo association gets unit privacy without losing the manager’s override. On Robinwood Ave we pulled original skeleton-key cylinders out of a 1910 Sargent mortise set and rebuilt the entire system in one day without altering the antique hardware. Call (331) 310-8471 and we’ll scope your building’s setup in writing.
