Emergency Mobile Auto Key Replacement Done at Your Car

Car Key Replacement sounds simple, but doing it well takes the right equipment and experience. Our technicians have both: key blanks, cutting machines and dealer-level programming tools, and more than two decades of jobs across Suffolk County.

We work wherever your car is — at home, at work, in a parking lot or at the roadside, and we test every key, lock and remote before we leave.

Many of our calls come from West Islip, Brentwood and Melville and the area around Jones Beach.

Also Available

  • Mobile locksmith and auto locksmith service at your car — no tow
  • Toyota and Lexus laser cut keys and smart keys
