Connecticut Locksmith Services

Homes and doors across Connecticut

In the Census Bureau's 2024 American Community Survey, about two-thirds of Connecticut's 1.55 million housing units were built before 1980. About one in five dates from 1939 or earlier, and fewer than 6 percent from 2010 or later.

Almost six in ten homes are detached single-family houses. About 15 percent sit in buildings with two to four units. That share includes three-deckers, found in Connecticut's former industrial centers and most commonly built in New England between 1870 and 1920.

What that means for locks:

• Pre-war doors. A house built before 1940 may still have a mortise lock set into a pocket in the door edge. Replacing it with a modern deadbolt can mean altering the door, so repair or rekeying is often simpler.
• Shared entries. In a two- to four-family house, one household may use a shared front door, its own unit door and a rear porch door. Check which of them the owner controls.
• Postwar houses. Roughly four in ten homes date from 1950 to 1979, so many may still have original hardware and keys copied many times over. Lock rekeying resets who holds a working key without replacing the lock.

How Connecticut's climate affects locks and keys

NOAA's state climate summary puts Connecticut's average January temperature at 27.2°F. Seasonal snowfall runs from 30 to 35 inches along the coast to about 50 inches in the Northwest Hills. Falls Village averages seven days a year below 0°F, Hartford two and New Haven one. During a February 2013 blizzard, Ansonia recorded 36 inches of snow in 24 hours, a state record.

• Frozen cylinders inland. Meltwater can refreeze inside an exterior lock overnight. Use a dry lock lubricant rather than oil, and never force a key that will not turn; a snapped key needs broken key extraction.
• Long power outages. In the 2011 Halloween nor'easter, more than 700,000 Connecticut residents lost power, some for more than a week. If a smart lock relies on Wi-Fi or an app, change its batteries before winter and keep the backup key within reach.
• Shoreline storms. Superstorm Sandy brought coastal flooding of 5 to 6 feet in 2012, including 5.3 feet at New Haven. After flooding or salt spray, rinse, dry and relubricate exterior locks.

Renting in Connecticut: locks, keys and entry

This is general information, not legal advice.

• Lock changes for protected tenants. Under Conn. Gen. Stat. § 47a-7b, a tenant protected by a court protective or restraining order requiring the other party to stay away from the tenant's home, or a set distance from the tenant, may give the landlord a copy and ask for new locks. Within six hours the landlord must say whether it will change them or let the tenant do so; if the landlord does it, the deadline is 48 hours. A digital lock may get a new entry code instead.
• Keys and costs. For a § 47a-7b lock change, the landlord pays any locksmith it hires, gives the tenant a new key and may charge only the actual reasonable cost; an unpaid charge cannot be the basis for an eviction. If the landlord leaves the job to the tenant or misses the deadlines, the tenant may install locks of similar or better quality and must give the landlord a key within two business days unless good cause prevents it.
• Landlord entry. Under § 47a-16, a tenant may not unreasonably refuse entry for inspections or repairs, and the landlord must give reasonable notice and come at reasonable times. Without consent, a landlord may enter only in an emergency, under a court order, after the tenant abandons or surrenders the unit, or as § 47a-16a allows.
• Lockouts by a landlord. Under § 53a-214, a landlord, lessor, owner or agent who, without a court order, keeps a tenant out of the unit or away from their possessions commits criminal lockout, a class C misdemeanor.
• Key deposits. Section 47a-4d bars most up-front charges, including move-in and move-out fees, but allows a deposit for a key or special equipment.
• Move-in walk-through. For rental agreements made on or after January 1, 2024, § 47a-7c requires the landlord to offer a pre-move-in walk-through on the Department of Housing checklist, which can note a sticking lock or missing key.

Before you book a locksmith in Connecticut

The Department of Consumer Protection (DCP) takes complaints about businesses online or by mail, email or fax.

1. Get the total cost in writing and keep the receipt. DCP asks for copies of receipts and other paperwork with a complaint.
2. Try the business first. DCP advises raising a problem with the business before filing.

DCP reaches out to the business to seek a reasonable resolution, which can take four weeks or more. It represents the state, not individual consumers, so an unresolved dispute can still go to small claims court.
