Do you serve the Neponset River area and River Street?

Yes — we cover all of Mattapan including River Street, the Neponset River neighborhoods, and the streets that border Dorchester and Hyde Park. If you're near the Mattapan trolley terminus or farther out toward Canton Street, we dispatch and arrive prepared.

Can you rekey my Mattapan multi-family building?

Absolutely. Multi-unit rekeying is one of our most frequent jobs in Mattapan. We reconfigure every unit's cylinders to a new key set in a single visit, so no previous tenant can walk back in. We can also set up a master key system for landlords managing four or more units along Blue Hill Avenue or Cummins Highway.

Do you handle commercial locks for Blue Hill Avenue businesses?

Yes. We install and rekey commercial-grade deadbolts, panic bars, and high-security cylinders for restaurants, shops, and service businesses along Blue Hill Avenue and throughout Mattapan Square. We schedule around your hours and can perform rekeying or installation after your closing time to minimize disruption.

Expert Locksmith Services for Mattapan

I'm Ray, owner of City Locksmith 24/7. Working in Mattapan has been a highlight lately—there is such a strong sense of community here, especially along the Blue Hill Avenue corridor. When I was out here on July 6 for a job, I was reminded of how important these historic triple-deckers and local small businesses are to the area. Whether you are dealing with an older lock that needs delicate restoration or a modern commercial storefront needing a security upgrade, my team brings the same level of care to every job.

Fast Apartment & Multi-Family Lockouts

Mattapan's housing stock is primarily multi-family — triple-deckers, two-families, and garden apartment complexes line the side streets off Blue Hill Avenue and Cummins Highway. Lockouts here are common: lost keys, broken cylinders, and worn deadbolts that finally give out. Our emergency lockout service runs 24/7. We use non-destructive picking tools to get you back inside quickly — no damage to the door, no surprise charges, and a flat rate quoted on the phone before we arrive.

Smart Lock Upgrades for New Construction

Mattapan is seeing new construction alongside its established housing stock — renovated apartments and newly built units are increasingly adopting keyless entry systems. We install and configure smart locks and Wi-Fi deadbolts that give you complete access control from your phone. For landlords managing multiple units along Blue Hill Avenue or Cummins Highway, smart locks eliminate the overhead of physical key management entirely.

Historic Lock Repair for Older Homes

Many of Mattapan's older multi-family homes and single-family residences still have original mortise locks that have been in service for decades. Instead of replacing them, we specialize in antique lock repair: carefully disassembling, cleaning, re-springing, and restoring your original hardware so it functions reliably again. Preserving the existing hardware keeps your costs down and maintains the character of older Mattapan homes.

Lock Installation for Mattapan Homes & Businesses

Whether you're replacing worn-out hardware on a triple-decker or outfitting a new Blue Hill Avenue storefront, we supply and install commercial-grade and residential deadbolts that meet Massachusetts egress code. Our lock installation service includes proper door prep, strike plate reinforcement, and a function test before we leave.

Lock Rekeying for Tenant Turnover

Mattapan's rental market turns over steadily. Every turnover is a security gap if you don't rekey. Rekeying your locks means we reconfigure your existing cylinders to work with a new key set — without replacing any hardware — for a fraction of the cost of new locks. We can also set up a master key system for landlords overseeing four or more units, letting you access every door with one key while each tenant retains complete privacy.

Commercial Locksmith Services on Blue Hill Avenue

Blue Hill Avenue is Mattapan's main commercial corridor — a mix of restaurants, convenience stores, professional offices, and service businesses. Commercial locksmith services here require hardware that holds up under heavy daily use while meeting Massachusetts building and fire codes. We install high-security cylinders, panic bar hardware, and access control systems for multi-tenant commercial buildings and owner-operated businesses across Mattapan.
