Why Strongbox Lock & Safe Co. Is Randolph’s Preferred Lock Installation & Rekey Company
We’ve been serving communities like Randolph for over 42 years, and the pattern here is distinct. This is one of the most demographically diverse and rapidly-turned-over communities in Massachusetts, driven by decades of migration from Boston’s Mattapan and Dorchester neighborhoods. That churn produces an unusually high volume of rekeying calls after unit changeovers - not emergency lockouts, which dominate in quieter suburbs like Canton or Stoughton. We know the difference, and we stock accordingly.
Randolph customers tell us the same thing: they have been burned by the $19-ad locksmith who quoted one price and invoiced another. We don’t operate that way. Gil Navarro built this company on flat prices quoted by a live person, before the truck leaves. Our technicians are background-checked, uniformed, and present ID at the door on every visit. Every job carries the 90-Day Done Right Promise - backed in writing, no paperwork, no arguing. If it is not right, we come back.
Calls are answered by a live person, 24/7, including nights, weekends, and holidays. No voicemail trees. No callback queues.
Our Lock Installation & Rekey Services in Randolph
Smart Lock Installation
Smart locks make sense for Randolph’s high-turnover rentals, but the installation is rarely plug-and-play. Many of the converted two- and three-families near North and South Main Street still run original 1950s-1970s door prep - smaller bore holes, thinner stiles, or composite fillers where old hardware was swapped. We retrofit Schlage Encode and Yale Assure locks to fit properly without chewing through vintage jambs. For landlords managing multiple units, we can network locks under a single master account so you’re not resetting codes between tenants. Typical smart lock installation in Randolph runs $220-$380, including rekeying to match existing master key systems where possible.
Keyless Entry & Keypad Lock Installation
Keypad locks eliminate rekeying costs between tenants, which matters in a market where unit turnover can happen twice a year on the same property. We install Kwikset SmartCode and Schlage keypad deadbolts on Randolph’s multi-family entries regularly, especially along the Route 28 corridor where landlords are trying to reduce locksmith callbacks. The key is matching the lock to the door: many converted capes have steel-edge fiberglass doors that require longer through-bolts, or original wood doors that have been oversanded and need backing plates. We measure on-site and quote flat. Keypad installation in Randolph typically runs $180-$320.
Biometric Lock & Electronic Lock Installation
Biometric and electronic locks are less common in Randolph’s rental stock but appear increasingly on owner-occupied units in the better-maintained postwar ranches. We install fingerprint-enabled deadbolts and Bluetooth-equipped electronic sets for homeowners who want keyless convenience without sacrificing the familiar turn-knob backup. These installs demand precise door prep and clean wire routing on electrified models. We handle the full range, from simple battery-powered biometrics to hardwired electrified mortise sets. Electronic and biometric installation in Randolph runs $280-$520 depending on door condition and power source.
Key Duplication & Rekeying
Rekeying is the backbone of our Randolph business. We recently rekeyed a converted ranch on North Main Street where the landlord had three units sharing a passage knob interior door - no deadbolt - a common code gap here. We installed Schlage B60 deadbolts on all unit entries and rekeyed to match, solving a security risk we flag on nearly every rekey in that corridor. Standard rekeying in Randolph runs $120-$180 for up to six cylinders; key duplication is $4-$8 per key for standard Kwikset or Schlage blanks, $12-$18 for Medeco or high-security profiles.

Trusted Brands We Service in Randolph
We install and service Schlage, Kwikset, and Medeco daily in Randolph, and we carry common cylinders, tailpieces, and strike plates on every truck. That matters when you’re rekeying a three-family on a Saturday afternoon and the landlord needs matching keys before Monday. We also work with Mul-T-Lock, Abloy, Baldwin, Yale, and Sargent for specialized applications - high-turnover rentals that need restricted keyways, or owner-occupants upgrading to Grade 1 commercial hardware on residential doors. Parts in hand means no second trip, and no waiting on a distributor in Boston.
Common Lock Installation & Rekey Problems We See in Randolph Homes
- Freeze-throw deadbolt misalignment. Eastern Massachusetts freeze-thaw cycles cause the wood door frames and jambs on Randolph’s older housing stock to swell in autumn and contract in late winter, frequently throwing deadbolts out of alignment with strike plates. This spikes in October-November and again in March, especially on the town’s less-maintained multi-family rentals.
- Original knob-lock-only hardware on converted units. Many post-WWII cape cods and ranches were converted to two- or three-family use without upgrading security hardware. We still find original knob-lock-only entries on rental units, especially in the blocks off Route 28, where a simple locked door is the only barrier between tenants.
- Landlord-supplied rekey kits that don’t match. High churn means some Randolph landlords buy online rekey kits that don’t match the local lock brand or cylinder depth. The key turns halfway, or the cylinder binds, and we get called to fix what should have been a straightforward rekey.
- Interior unit doors with passage knobs and no deadbolts. In the denser residential blocks off North and South Main Street, many converted two-families were never brought up to code on interior unit separation. Installing deadbolts without disturbing existing passage sets requires careful drilling and matching finishes - work we do weekly in this corridor.

We Also Serve Cities Near Randolph
Our trucks cover Braintree, Holbrook, Canton, and Stoughton regularly, but Randolph’s lock market is its own animal. The density of converted multi-family housing and the pace of tenant turnover here create a different service profile than the quieter owner-occupied streets of Canton or the more commercial mix in Braintree. We know both, and we dispatch accordingly.

FAQs - Lock Installation & Rekey in Randolph
Smart locks can reduce rekeying costs between tenants, but they require reliable Wi-Fi and tenant education. In Randolph’s high-churn rental market, we typically recommend keypad deadbolts over full smart locks for units under $2,000/month - simpler to reset between tenants, fewer support calls. For higher-end conversions or owner-occupied units, the Schlage Encode Plus integrates well with most phones. Call (877) 664-8139 and we’ll assess your specific property.
Freeze-thaw cycles in eastern Massachusetts swell wood jambs in autumn and contract them in late winter, throwing deadbolts out of alignment with strike plates. This is predictable on Randolph’s 1950s-1970s housing stock, especially less-maintained multi-family rentals. The fix is usually strike plate adjustment or replacement, not a new lock - $120-$180 in most cases. Call (877) 664-8139 for a free look.
Yes, if the lock cylinders are compatible. We can key alike Schlage, Kwikset, and most standard brands across multiple units so one master opens common entries and individual keys open private doors. We do this regularly for Randolph landlords managing converted two-families near North Main Street and Route 28. The rekey typically runs $180-$260 for a duplex with four to six cylinders. Call (877) 664-8139 to check your current hardware.
Schlage B60 deadbolts and Kwikset SmartCode keypads hold up best in our experience with Randolph’s rental market - durable, widely available, and tenants already know how to use them. Medeco restricted keyways are worth the upgrade if you’ve had unauthorized duplication issues. We stock all three and can match finishes to existing hardware. Call (877) 664-8139 for a recommendation based on your building.
Current Massachusetts building code requires lockable separation between dwelling units, and many converted Randolph two-families - especially off Route 28 and near South Main Street - still rely on passage knobs with no locking function. We flag this on nearly every rekey call in those corridors. Installing deadbolts without replacing the passage set runs $140-$220 per door. It’s a straightforward upgrade that protects both tenants and liability. Call (877) 664-8139 for a free assessment.
