We're Cobalt Locksmith Pros, a locksmith that works out of Marlborough, MA and comes to you. Every job is done where the lock is, whether that's a driveway, a front door or a storefront, and the phone goes to our own dispatch around the clock, not a call center. Open 24 hours.



One call is enough. Tell us where you are and what's locked, and dispatch calls you back within minutes with a time. The technician rings ahead, looks at the door or the car, and tells you plainly what the job is before touching anything. Nothing begins until you've said yes.
Two things we've learned about Marlborough: A hard freeze is what turns a stiff lock into a broken one. If a key will not turn in the cold, stop before it shears. This is a commuter town, so lockouts cluster early morning and after the evening run home, when nobody is around to hold a spare. The stock on board reflects that.
A few things you won't get from us: a technician who isn't ours, a new-lock pitch when rekeying would do, or an entry without checking that the person asking is allowed in. And we don't describe how locks are bypassed, here or anywhere else. That's deliberate.
The normal radius takes in Marlborough and Boston, Worcester, Providence, Lowell, Cambridge, Dorchester. Just outside it is still worth a call; the radius is about drive time rather than lines on a map, and emergency calls run to the same map at night.
Yes. Open 24 hours, including holidays. A lockout at 2am is exactly the call we keep room for.
No, and that's on purpose. Cobalt Locksmith Pros is fully mobile, so the work is done wherever the lock is: your driveway, your door or your business.
For a lockout, yes. It's the check that keeps us from opening someone's door for the wrong person, and it takes a moment.
No. The technician who comes out works for Cobalt Locksmith Pros.
