Not just anyone can properly install a security gate. It involves a combination of craftsmanship as well as experience in electrical configuration and security systems. Having a background in architectural design and landscaping insures that your gate is not only secure, but attractive as well.

M&D Locks and Keys incorporates security gate installation and maintenance in all of its training so when we send a technician to your home or business, you’re getting a trained and experienced professional.

Common gates around Brooklyn include building entrance gates, tree guards, custom fire escape units (approved by the fire department), window gates, stair rails and custom ironwork. We also carry aluminum, wooden, stainless steel systems as well as electric opening units, Bi-fold, chain link, swing, vertical and slide lift gates. We can customize any outdoor entrance to meet your needs, whether its residential or commercial.

Our Professional Team

M&D locksmith and security system professionals are typically available 24 hours a day, though for security gate requests, we usually ask for some preparation time before we meet you for an inspection or to provide a quote. We want to make sure we provide you with the best service possible. We service New York and New Jersey consumers in Manhattan, Brooklyn, Queens, Staten Island, the Bronx and Long Island.

Combined Systems

It is common for security gates to work in conjunction with other security systems such as security cameras, home surveillance or intercom units. M&D professionals are trained in all home and commercial security so be sure to ask us about other ways to completely secure your property. Or, please visit our pages on security cameras, intercom units or access control systems for more information.

We’ll get to you in 20 minutes or less.

Garage Doors

If you are one of the few lucky car owners who has a garage, we can install a security garage door for you as well. For some estate homes and commercial properties, it is not uncommon for us to install a dual security gate/garage system. These are a bit more complicated, but can give your property the most protection, especially when combined with security cameras and other surveillance devices.

Please let us know if you’d like us to design a complete home or business security system for you. Most jobs like these are highly customized, but please ask us your M&D technician for more information.

We want to be your home and security advisors so our technicians are trained and experienced in many more areas than most NYC locksmiths. We are your go to company for locks, keys and security.
