Losing the only key to your car, or finding that your spare no longer works, does not have to mean a tow to the dealership. HMS Locksmith brings the key blanks, cutting machines and programming equipment to your vehicle, whether it is parked at home, at work or in a lot anywhere in the greater Boston area.
Most vehicles now use transponder chip keys, remotes or proximity keys that are coded to the car. A key that is only cut will turn the lock but will not start the engine. We cut the new key to your locks and program it to the vehicle’s onboard computer so it starts the car. If a key was lost or stolen, we can erase its code so it no longer works.
CAR KEYS AND FOBS WE REPLACE
- Standard metal car keys
- Transponder chip keys
- Key fobs and keyless entry remotes
- Proximity and push-to-start keys
- Spare keys and duplicates of a working key
For the details of chip keys and remotes, see transponder key replacement and car key programming. If your key is stuck or broken in the ignition, we also handle ignition repair.
WHY NOT GO TO THE DEALER?
A dealership usually needs the car brought in, which can mean a tow when you have no working key, and you may wait for a key to be ordered. We carry a large inventory of keys for new, old and rare vehicle models and program them on site, at rates far lower than dealerships. If you are locked out as well, our car lockout service gets you back inside first.

CAR KEY REPLACEMENT FAQ
Can you make a car key without the original?
Yes. If all of your keys are lost, we can open the car, cut a new key to the locks and program it to the vehicle on site for many makes and models.
How long does car key replacement take?
Programming a new remote typically takes 10 to 20 minutes at your car. A full replacement key depends on the vehicle, and we will give you an estimate when you call.

We can erase lost or stolen transponders from the vehicle’s onboard computer so they can no longer start the car.
