Quick Advice
- Be careful with cheap online fobs — many are the wrong frequency for your car.
- Replace key fob batteries every couple of years, before they fail.
- Keep a spare somewhere other than the car itself.
- Don't force a key that won't turn; check that the steering lock isn't engaged first.
Frequently Asked Questions
Do you work on all makes and models?
We carry keys and programming for most cars, SUVs, vans and pickups. Call with the year, make and model and we confirm right away.
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.
Do I need to bring the car to you?
No. We are a mobile locksmith: the technician comes to your car at home, at work or at the roadside.
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.
How fast can you get to me?
Most calls are reached within the hour. We give you an arrival window when you call.
Do you repair remote head keys?
Yes. Honda and Toyota remote head repair is one of our most common jobs — a new shell, buttons or blade often costs far less than a new key.
How long does it take?
Most key replacements and programming jobs are finished within an hour of arrival. We tell you what to expect when you call.
Are your technicians licensed and insured?
Yes. We are a licensed locksmith in New York State, every technician is insured, and we verify ownership before every job.
