24 Hour Mobile Auto Key Replacement From a Mobile Locksmith

Car Key Replacement means cutting and programming new car keys at your vehicle, for every common key type and most makes. Because we are fully mobile, the work happens wherever your car is — at home, at work, in a parking lot or at the roadside.

We start by confirming you own the vehicle, then do the job with professional tools and test everything with you before we leave. If something else turns up — a worn ignition or a fob with a dead battery — we tell you and quote it before doing anything.

Smart Habits

  • Keep a spare somewhere other than the car itself.
  • If a smart key dies, look for a hidden metal blade inside it.
  • Have the year, make and model ready — it speeds up the quote.
  • If a key breaks in the lock, leave the piece in and call us rather than digging at it.

The Car Key Locksmith Difference

  • We come to you — no tow, no dealership appointment, no waiting days for parts
  • Dealer-level programming equipment in every van
  • Real people answer the phone, not a call center
  • Everything tested before we leave — doors, ignition, trunk and remote buttons
  • Weekends and holidays included, at the price we quote
  • Work tested in front of you before we leave

Other Services We Offer

  • Home and house lockouts too — we open front doors and change locks
  • Lost car keys, no spare? A new key made from the VIN, right at the car
  • GM laser cut keys for Chevrolet, GMC, Buick and Cadillac
  • Laser cut key duplication — high-security sidewinder keys cut on our laser key machine
  • Honda and Acura ignition and key service, from worn ignitions to new remote-head keys

Everything We Handle

  • Most makes and models, from basic metal keys to push-to-start smart keys
  • All-keys-lost situations handled — no original key needed
  • Transponder, remote-head, flip and smart keys programmed to your car
  • New keys cut from the VIN, a code or by decoding the lock
  • Emergency blade cut for smart keys, for when the battery dies
  • Spare keys made at the same visit
  • Lost keys erased from the car's memory where supported

How the Visit Works

Most calls follow the same simple pattern:

  1. Call (516) 750-0433 with your location and the year, make and model.
  2. We quote the job and give you an arrival window.
  3. The technician confirms ownership, then cuts and programs the new key at your car.
  4. You test the key in the doors, the ignition and the remote before we leave.

Upfront Pricing

Here is what moves the price up or down:

  • How many keys you want
  • The type of key (basic, transponder, remote-head, flip or smart key)
  • The make and model

Compared with the dealer, most drivers save both money and time — and skip the tow. There are no hidden call-out fees: what we quote is what you pay.

Who We Are

We started in 2001 with a simple idea: bring the locksmith to the customer. More than twenty years later, that is still how we work — at your car, day or night.

Car Key Locksmith is a local business, not a national call center. Since 2001 we have answered our own phones, quoted our own jobs and sent our own technicians.

Frequently Asked Questions

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 fast can you get to me?

Most calls are reached within the hour. We give you an arrival window when you call.

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.

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.

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.

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.

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.

Do you offer 24 hour lockout service?

Yes. Car lockouts and auto lockouts are handled 24 hours a day, every day of the year. Call (516) 750-0433.
