Frequently Asked Questions
How long does a replacement take?
Most key replacements are done within an hour of arrival; some European systems take longer, and we tell you when you call.
Can you replace a key for any car?
We carry keys and programming for most cars, SUVs, vans and pickups. Call with the year, make and model and we will confirm right away.
Can you do 24 hour mobile auto key replacement in Smithtown on site?
Yes. We are fully mobile and come to your car anywhere in Smithtown, NY 11787, so there is no towing involved.
What should I have ready when I call?
Your location, the year, make and model, and your ID with the registration or title for when the technician arrives.
Is replacing a car key cheaper than going to the dealer?
Usually, yes — and faster, because there is no tow, no parts order and no appointment. You get the price before we come out.
Can you cut laser cut keys?
Yes. We cut laser cut (sidewinder) keys on site, including Honda, Acura, GM, Toyota and Lexus laser cut keys, and program them to the car.
