24 Hour Auto Key Duplication – Licensed & Insured

Licensed Locksmith — over 20 years experience, 2001–2026

Local, licensed and mobile: spare car keys cut and programmed at your car across Nassau County.

Looking for 24 hour auto key duplication? Car Key Locksmith handles car key duplication — making spare keys — cut and programmed — while you still have a working key — anywhere in Nassau County, Long Island and Queens, 24 hours a day. Car lockout, auto lockout or a key that won't turn in the ignition — one call covers it.

We confirm you own the vehicle, do the work at your car, and walk you through the result before we go. We are licensed and insured, and we have been doing this work in Nassau County since 2001.

24 Hour Auto Key Duplication Since 2001

Not every locksmith comes to you. Car Key Locksmith does — that is the whole idea. Our car key duplication brings key blanks, cutting machines and dealer-level programming tools to your car, day or night.

We are just as busy in nearby Port Washington, Kings Point and Old Bethpage.

Everything We Handle

  • Valet keys that open the doors but not the trunk or glovebox, where available
  • Spare keys cut to match your working key exactly
  • Remote and smart key spares paired with the car
  • Most makes and models, from basic metal keys to push-to-start smart keys
  • Several spares at once for family members and fleets
  • Transponder chips programmed so the spare actually starts the car

Why Locals Choose Us

  • Clean, careful work that respects your time and property
  • Upfront pricing — you get the price before we dispatch, with no surprise fees on arrival
  • Honest advice, even when the fix is simple
  • Usually cheaper and faster than the dealer
  • Everything tested before we leave — doors, ignition, trunk and remote buttons

Pricing, Explained

For 24 hour auto key duplication, the quote comes down to:

  • Whether the key needs programming as well as cutting
  • The type of key being copied (basic, transponder, remote-head or smart key)
  • How many spares you want

Local Coverage

Nassau County is home base, and we regularly work in Hewlett, Lawrence, Locust Valley, Mineola and Lynbrook. We also cover Queens and much of Suffolk County.

What to Expect

  1. Call (516) 750-0433 with the year, make and model and the type of key you have now.
  2. We quote the spare and an arrival time.
  3. The technician cuts the new key from your working key and programs it.
  4. You test the spare in the doors and the ignition before we leave.

  • Toyota and Lexus laser cut keys and smart keys
  • 24 hour lockout service for cars, SUVs, trucks and vans, nights and weekends included

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.

Do you have dealer programming tools?

Yes. We use dealer-level software, including Ford FDRS and GM GDS2, to program keys on newer Ford and GM vehicles that generic tools can't reach.

Do you also handle home and business lockouts?

Yes. Along with car lockouts we open houses, apartments and commercial doors, and change or rekey locks.

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.

Can you do 24 hour auto key duplication on site?

Yes. We are fully mobile and come to your car, so there is no towing involved.

Which areas do you cover?

All of Nassau County, much of Suffolk County and Queens, including JFK Airport, Jones Beach, Resorts World Casino and UBS Arena.

Is it cheaper than 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.

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.

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.

Talk to a Real Person

Lost keys, lockouts, fobs or ignitions — we come to your car, day or night.
