Mobile Lost Car Key: The Basics

Our lost car key replacement is mobile from start to finish. There is no tow, no dealership appointment and no waiting days for parts; we bring everything needed to your car.

From Williston Park, East Meadow and Freeport, Car Key Locksmith is on call 24/7.

From Basic Keys to Smart Keys

Domestic, Asian or European, we have you covered: Ford, Audi, Mercedes-Benz, Acura, Toyota, Lexus and Volvo, among others. We handle transponder chip keys, basic metal keys and push-to-start smart keys.

What the Visit Includes

• Emergency blade cut for smart keys, for when the battery dies
• Remote functions paired: lock, unlock, trunk and panic
• A new key originated from the VIN or by decoding your door lock — no original needed
• Transponder chip or smart key programmed to your car's immobilizer so it actually starts

How It Works

1. Call (516) 750-0433 with your location, the year, make and model, and whether any key still exists.
2. We quote the job and give you an arrival window.
3. On site we verify ownership, then cut the new key and program it to the car.
4. We erase the lost keys from the car's memory where possible and test everything with you.
5. We answer any questions before the technician heads off.

The Car Key Locksmith Difference

• Dealer-level programming equipment in every van
• Work tested in front of you before we leave
• 24/7 emergency service — a real person answers day and night, weekends and holidays
• Real people answer the phone, not a call center
• Weekends and holidays included, at the price we quote
• Everything tested before we leave — doors, ignition, trunk and remote buttons

Two Decades of Calls

We have been part of the Nassau County community for more than twenty years. That local experience is why so many neighbors recommend us.

Services Customers Ask For

While we are there, we can also help with:

• 24 hour lockout service for cars, SUVs, trucks and vans, nights and weekends included
• Remote repair and car key repair, often far cheaper than a new key
• Toyota remote head repair and key fob shell replacement
• Honda remote head repair — a new shell, buttons or blade for a worn remote-head key
• Honda and Acura ignition and key service, from worn ignitions to new remote-head keys
• Toyota and Lexus laser cut keys and smart keys
• Commercial door lockouts for offices and storefronts

Good to Know

• Get a spare made while you still have a working key — it costs far less than an all-keys-lost call.
• Keep a spare somewhere other than the car itself.
• Replace key fob batteries every couple of years, before they fail.
• Test the remote buttons and the trunk with the technician before we leave.

Mobile Lost Car Key Pricing

We keep pricing simple and upfront. It depends on:

• Whether the car needs its immobilizer module accessed to program an all-keys-lost key
• Whether you want spare keys made at the same visit
• The make — some European systems take extra equipment and time
• The type of key: basic transponder, remote-head, flip key or push-to-start smart key
