Frequently Asked Questions

Will a hardware-store copy start my car?

Usually not. Most cars since the late 1990s need a programmed transponder chip, which a plain cut copy doesn't have.

Can you copy a push-to-start smart key?

Yes. We program an additional smart key to your car while your existing key is present.

Why get a spare before I lose my key?

Adding a key while you still have one is far simpler and cheaper than an all-keys-lost replacement — often a fraction of the cost.

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.

Do you work weekends and holidays?

Yes. We work every day of the year, and the price is always quoted before we come out. Call (516) 750-0433.

How much will it cost?

It depends on the vehicle and the key or lock involved. Call (516) 750-0433 with the year, make and model and we give you the exact price before we dispatch.

What if I have lost every key and have no spare?

We can still make a new key. With your ID and the registration or title, we originate a key from the VIN or the locks and program it to the car.

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.

Will you tell me the price before you come?

Always. You get the price on the phone, before a technician is dispatched.
