Deadbolt Installation
Brooklyn doors take a beating. From the double-locked brownstone gates along Prospect Park West to the steel entry doors of Flatbush apartment buildings, the locks protecting your home work hard every single day — and when they fail, the consequences are real. Ralph Locksmith Corp is a fully mobile, insured locksmith service operating 24/7 across Brooklyn, NY, and deadbolt installation is one of our most-requested jobs. Whether you're moving into a new place on Nostrand Avenue, upgrading after a break-in attempt on your block, or simply replacing a worn-out single-cylinder lock with something stronger, our trained technicians come directly to your door — no shop visit, no waiting.

Choosing the right deadbolt and having it installed correctly are two very different decisions, and both matter. A high-grade Schlage or Kwikset deadbolt thrown into a poorly fitted door frame offers surprisingly little real-world security. Our experienced team doesn't just swap hardware — we assess the entire door assembly, the strike plate, the frame reinforcement, and the alignment of the bolt throw before any work begins. The result is a deadbolt installation that actually holds up, installed damage-free wherever possible, with an exact up-front price confirmed before we touch a thing. Call (718) 866-3646 any time — day or night, we answer.
