Door Lock Repair
When a deadbolt sticks, a knob cylinder spins freely, or a mortise lock stops latching, the problem rarely fixes itself — and in a borough as busy as the Bronx, a faulty lock is a security gap you cannot afford to leave open. Tremont Ave Locksmith Inc sends trained, insured technicians directly to your door, whether you are on Tremont Avenue itself, near the Grand Concourse, or tucked into a side street in Pelham Bay. We diagnose and perform door lock repair on-site, working with the hardware already installed whenever possible so your door frame stays intact.

Frequently asked questions
Answers to what our customers ask most. Still unsure? Just call.
How much does a locksmith charge on average for door lock repair in the Bronx?+
The final price depends on several factors: the type of lock involved (a standard deadbolt differs significantly from a multi-component mortise lock), whether parts need to be sourced, the time of day the call comes in, and travel distance within the Bronx service area. Emergency calls at off-peak hours may carry a different rate than a scheduled daytime appointment. What we never do is give you one price over the phone and a different one at the door — we confirm an exact amount before any work begins so you can make an informed decision with no pressure.
How do I know if a locksmith is legitimate before I let them work on my door?+
A legitimate locksmith will clearly state their business name and service area before arrival, show identification at your door, and provide a firm price before touching any hardware. They should not demand payment before you can see the technician's credentials or before they explain what the repair requires. At Tremont Ave Locksmith Inc, our insured technicians arrive with identification, explain their findings in plain language, and confirm your price up front. If a locksmith refuses to do any of these things, consider it a red flag.
Can you repair my mortise lock without replacing the whole door unit?+
In most cases, yes. Mortise locks are repairable in place when the problem is isolated to a worn spring, a stripped cylinder, a broken lever, or a misaligned latch. Our technicians inspect the full assembly first and recommend repair when the lock case itself is structurally sound. Replacement of the entire mortise lock case is only suggested when the body is cracked, the internal mechanism is too corroded to service, or when upgrading to a higher-security grade makes more practical sense for the property.
How do I change the code on my keypad door lock, and can you help if I cannot figure it out?+
Most keypad door locks follow a manufacturer-specific sequence — typically involving a master code or a physical reset button before allowing a new user code to be entered. The exact steps vary by brand and model, and the manual is the right starting point. If you have lost the manual, the manufacturer's website usually carries a downloadable version. If you have inherited a lock with an unknown code or the reset process is not working, our technicians can walk you through it on-site or perform a full factory reset and reprogramming during a service visit. This is a common request after tenant turnover in Bronx rental properties.
What zip codes in the Bronx do you serve for door lock repair and emergency locksmith calls?+
We cover the entire Bronx, including zip codes 10451 through 10474. That covers neighborhoods from Mott Haven and Hunts Point in the south to Riverdale and Woodlawn in the north, and everything in between — Fordham, Tremont, Parkchester, Co-op City, Pelham Bay, Kingsbridge, and more. If you are unsure whether your address falls in our range, call (929) 822-6640 and our dispatcher will confirm coverage immediately.
Does changing a door lock always mean replacing the entire knob or deadbolt assembly?+
Not necessarily. Changing a door lock can mean different things depending on the problem. Re-keying the existing cylinder is the most minimal option and leaves all hardware in place while making old keys useless — ideal after a move or after losing a key. Replacing only the cylinder is the next step up when the cylinder is damaged. A full lock replacement, meaning new knob or deadbolt hardware, is warranted when the internal mechanism is worn beyond repair or when a security upgrade is the goal. Our technicians explain each option and its cost factor clearly so you choose what fits your situation, not what is easiest for us to sell.
