Keys locked in the car. A front door that closed behind you. A lock that has to change today because somebody still has a key to it. A car lockout, a house lockout, a lock change — those three are most of what a 24hr locksmith in Cambridge is called out for.
One call, and the emergency locksmith who takes the job comes to you — your driveway, your parking lot, wherever the car or the door is. A mobile locksmith covers Cambridge and the the towns around it, day or night. One number, since 2013.

The work happens at your car or your door, so the locksmith near you is simply whichever one is already working closest to where you are. At home, at work, or wherever you parked.
A locksmith near me in Cambridge usually means one of three calls: a car locksmith for somebody locked out of the car, a mobile car key locksmith cutting a new key at the car, or a house locksmith at a front door.
All three come down to one question — is somebody close enough to come out? For a locksmith in Cambridge, the answer is every town listed further down this page.

A car lockout is the call this line takes more than any other. Keys locked in the car, sitting on the driver’s seat and the door is locked, or they are somewhere in the parking lot and you have already walked it twice.
A car locksmith opens it right where it is parked — cars, vans, pickups and SUVs, doors and trunks, and the lock stays in one piece. Car door unlock is the whole job, and you drive the car away afterward. An auto locksmith near you covers Cambridge and every town listed further down this page, around the clock.
Two things move the call along: where the car is, and the year, make and model. And if you are locked out with the engine running, or with a child or a pet inside, say that first — it changes how the call is handled right away.
A key snapped off in a door or an ignition comes out on the same visit, and if the half still in your hand no longer works, a new one can usually be cut before the mobile locksmith leaves.

Every key gone, and no spare in a drawer anywhere. People expect that one to take a week and a trip to the dealership. It is usually one visit, at the car, with a mobile locksmith.
The new key is cut from the car’s own code instead of copied from a key you no longer have, which is exactly why it still works when every key is gone. Transponder chip keys, VATS keys, high-security laser-cut keys, proximity keys and push-to-start key fobs, on most makes and models. A mobile car key locksmith does the cutting and the programming at the car.
Key fob questions are worth asking separately, because a key fob replacement is often not what you need. One that has lost its pairing needs programming rather than replacing. One that only works when you are standing right next to the car is usually just a dead battery. And a fob you have already bought can often be programmed to your car if it is compatible.

Locked out of the house at three in the morning. Locked out on a Sunday. The keys on the kitchen table, visible through the glass, which is somehow worse.
An emergency locksmith opens the door rather than replacing it — front and back doors, patio and sliding doors, the garage side door, and the bedroom door that locked with the key on the wrong side. An apartment entrance and a buzzer panel are the same call, and a house locksmith near you covers Cambridge and the towns listed further down this page, at any hour.
If a child or a pet is locked inside and at risk, call 911 first. They can force entry immediately and a locksmith cannot, and no lock is worth the wait. The door still needs opening once everybody is safe, and that call can follow.

A move-in. A tenant who left. A set of keys that never came back and you would rather not wonder about it.
Rekeying is the quick one, and it is what a local locksmith near you does most. The lock stays on the door, the inside of it is re-pinned, and every old key stops working that day. A lock change swaps the hardware itself — deadbolts, knob sets, high-security cylinders and smart locks, or a first lock on a door that never had one.
After a break-in it is the same day’s work rather than the same week’s. A door that has been forced once will not hold the second time.

The first person in cannot get in, or the last one out finds the shutter jammed. Both happen before eight and after six, which is when this line is answered too.
Storefronts, offices, warehouses and multi-suite buildings. Business lockouts, a business lock change after a break-in or a staff change, master key systems so one key runs a whole site, restricted keys that a hardware store cannot copy, panic bars, access control and buzzer entry.
A fire door that will not latch, or a panic bar that has stopped releasing, is not a convenience problem. It is a door that fails an inspection, and fails people in the one situation it exists for. And when somebody leaves, a business lock change or a rekey covers every cylinder on the site in one visit rather than one job per door.

Six postal codes carry the Cambridge name across the river from Boston, a city of universities, triple deckers and permit parking where students, researchers and families all lock themselves out at some point. Apartment doors that latch behind a roommate, a car stuck on a side street with the keys inside, a key snapped in an old deadbolt: somebody picks up the phone at all hours and heads to the Cambridge address. Cars get a new key or fob coded right on the street, so nothing waits on a dealer. Somerville is a mile north east, Allston and Brighton two miles south, and Medford, Arlington, Brookline, Watertown and Belmont about three miles out. Old Cambridge locks are worked open gently and rekeyed on request.

Call 911 first, before anything else. Police and fire crews treat a child locked in a vehicle as an emergency and can force entry immediately, which no locksmith should wait to be asked to do. Once everyone is safe, the car still needs opening, and that call can follow.
The locksmith comes to the car, reads the code the vehicle was built with, then cuts and programs the new key on the spot. There is no tow and no dealership appointment, and it is done the same way anywhere in and around Cambridge — Allston, Brighton, Fenway, Charlestown and more.
Usually, and without replacing anything: front and back doors, patio and sliding doors, the garage side door, and the apartment entrance with a buzzer panel. It is the same call anywhere in Cambridge and across Allston, Brighton, Fenway, Charlestown and more.
Yes. A lock change after a break-in is treated as an emergency, because a door that has been forced once will not hold the second time. Board-up and a working lock are usually the same visit.
The job is done through the lock and the door is meant to come away unmarked — that is the whole reason an auto locksmith is called instead of anybody with a tool. If a vehicle turns out to need something that could mark it, you are told before it happens, not after.
Yes. The key is cut to the car’s own code rather than copied, which is exactly what makes it possible when every key is gone. Most makes and models are covered, including transponder chip keys and push-to-start fobs.
The aim is to open the door and leave the lock working, and on most residential locks that is what happens. Some locks cannot be opened that way — a high-security cylinder, or one that has already been forced — and those are drilled and replaced instead. Ask which of the two you are looking at, and agree it, before any work starts.
Yes. A commercial locksmith covers storefronts, offices and multi-suite buildings before opening and after closing, which is when a business lockout actually happens — anywhere in and around Cambridge, including Allston, Brighton, Fenway, Charlestown and more.
