What Decides the Cost

What we consider when we quote:

  • The type of key (basic, transponder, remote-head, flip or smart key)
  • Whether a working key is available or all keys are lost
  • How many keys you want
  • The make and model

Compared with the dealer, most drivers save both money and time — and skip the tow. We would rather give you an honest number on the phone than surprise you on arrival.

Why People Trust Us

  • Most makes and models covered, from basic keys to smart keys
  • An arrival window on the first call, so you are not left guessing
  • Dealer-level programming equipment in every van
  • No high-pressure upsells — we quote only what you need

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 make a spare key at the same visit?

Yes, and it is the best time to do it — a spare made now costs far less than an emergency replacement later.

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 long have you been in business?

Since 2001. Car Key Locksmith is based in Hewlett, NY, and has served drivers across Long Island and Queens for more than two decades.

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.

I lost my car keys and have no spare. Can you help?

Yes. With your ID and the registration or title, we make a new key from the VIN and program it to the car — no original needed.
