Being locked out is no fun, but with a 20-minute response time and 24/7 availability, M&D Locks and Keys has the best and most reliable emergency lockout service in the 5 boroughs. We have mobile units patrolling the city so chances are if you’re stuck, there’s an M&D professional, just around the corner.

Our mobile technicians go through rigorous lockout training and pre-screening to ensure your emergency is addressed quickly and honestly. Each one is trained and certified by the Associated Locksmiths of America (ALOA) so they can deliver the most efficient and reliable service to you.

M&D has something most other New York locksmiths do not—the ability to remake your lost, broken or stolen key on the spot. Our mobile units are equipped with the most advanced technology in the industry. They will make you a brand new key from their van, even if you do not have the original. This service is so specialized that many other locksmiths in the city often refer their customers to us, specifically for this service.

We know the scams as well as the tarnished reputation the locksmith industry has received over the years, especially in New York City.

Never trust a locksmith that shows up in an unmarked vehicle and especially one that cannot produce a valid locksmith license.

We know trust is important. Our goal is to make you so satisfied with our services that you’ll not only write a good review for us in Google and Yelp, but that you’ll add our telephone number to your mobile device should you need us in the future.

We’re contributing members of the New York community and are here to stay. We have two shops in Brooklyn and mobile units that patrol areas throughout the city. We’re trusted by the NYPD, New York City Sheriff, the US Marines and countless New York businesses such as Armani, Sleepy’s New York, Geico, the New York State Retirement System, Ted Baker Manhattan, Brookdale Residence and PM Pediatrics of Brooklyn as well as many others.

Reliability, honesty, integrity

There are a lot of scams out there. We understand the nature of the New York locksmith industry. It is plagued by crooks and opportunists. At M&D, we advocate for openness and honesty among the locksmith industry. That’s why many city, state and federal agencies such as the NYPD, New York City Sheriff and the US Marines trust us with their security. We’ll never show up in an unmarked car, we’ll never charge you more than what is fair and we will not break or destroy property unless it is with your permission and absolutely necessary to gain access.
