Car key replacement in Somerville

Mobile key making and programming in Somerville, MA. We come to your car — lost keys, spares, key fobs, push-to-start. 0 minutes — this is home base from the Somerville base.

Working in Somerville

Somerville is where I am based, on Highland Avenue. A call inside the city usually means a response inside the hour, often sooner. Whether the car is in a Union Square lot, curbside in Davis, or in the Assembly Row garages, I am close and the job is done at the vehicle.

Parking and getting there

Resident-permit street parking dominates the side streets, so I pull up curbside where the car is. In the Assembly Row garages, meet me at the garage entrance and I follow down to your level. Union Square during the evening rush is the slow window — avoid it if the job is not an emergency.

Vehicles in Somerville

A mix of compact sedans and crossovers suits the dense parking. Subaru Outbacks, Honda Civics, and Toyota Corollas are common, with a rising share of push-to-start Hyundai Elantras and Nissan Rogues from the newer buildings near Assembly.

A note on response time

Because the base is here, Somerville calls get the fastest response — most jobs finish inside the daytime window.

Questions about Somerville

How fast can you get to Somerville?
Usually within the hour and often within twenty minutes, depending on traffic around the squares. I give you an honest current response time when you call.
Can you make a key in an Assembly Row garage?
Yes. Meet me at the garage entrance and I follow to your level. The programming equipment runs off the vehicle battery, so no garage power is needed.
