Our Idea
For over 40 years, 23 CarKey Locksmith inc has been the trusted locksmith partner for Long Island families and businesses. Founded locally in 1984, we remain an independent, owner-operated business. Our idea has always been simple: combine big-company capability with small-business care. We know our customers by name, not by ticket number — and we show up every single time.
Our Tasks
We specialize in mobile car key replacement and programming for most makes and models. Whether you lost your keys, need a spare, or your smart key stopped working — we come directly to your location and handle everything on-site. Our daily tasks include key cutting, transponder programming, push-to-start key replacement, fob programming, car lockouts, house lockouts, and residential lock changes. Fast response, fair pricing, professional service every time.
Our Goal
To become the most trusted and fastest mobile auto-locksmith service on Long Island — by providing reliable car key programming, emergency lockout assistance, and advanced key solutions with a relentless focus on speed, professionalism, and customer satisfaction. Every five-star review we earn is proof that we're on the right track.

Our Story
Built on Trust. Driven by Service.
23 CarKey Locksmith inc was founded in 1984 right here on Long Island. What started as a one-man mobile operation has grown into a trusted, multi-technician company serving customers across Nassau and Suffolk County every single day. We have never lost sight of what matters most: showing up when you need us, treating your property with care, and charging a fair price. Our family has been part of this community for over four decades. Today, our fully equipped mobile vans cover all major towns — from Hempstead to Southampton, Great Neck to Patchogue. Every technician is background-checked, trained, and insured.
