When dealing with lost car keys, ordering a replacement online, or working with a mobile locksmith, one thing often comes up—the VIN number. VIN stands for Vehicle Identification Number. It’s a 17-character alphanumeric code that uniquely identifies your specific car, like a fingerprint for your vehicle.
At Austin Key Replacement, we often use the VIN to cut new keys, verify ownership, or look up your car’s key code. It’s the fastest and most secure way to confirm what key your car needs. Whether you're locked out, need a spare, or your key broke in the ignition, understanding the VIN is the first step toward fast and accurate service.

A VIN is a 17-digit string of letters and numbers assigned to every vehicle at the factory. This number contains encoded information about the vehicle's make, model, engine type, country of manufacture, and year of production.
Every VIN is unique, and no two cars have the same one. It’s used by government agencies, insurance companies, locksmiths, and mechanics to verify vehicle identity. If you’ve ever needed to file a police report or request service, you’ve probably had to provide this number.
Locksmiths like us at Austin Key Replacement use your VIN to retrieve key codes, especially when cutting a replacement key for newer cars with [transponder keys](transponderkey.html title="What Is Transponder Key?").
There are several common locations where the VIN can be found. The most visible one is on the dashboard, at the base of the windshield on the driver’s side. It’s often printed on a small metal plate behind the glass.
Other locations include the driver’s side door frame, your insurance card, vehicle title, and registration documents. Some vehicles even have the VIN stamped under the hood or inside the engine bay.
If you're locked out and can’t access the interior, we may still locate the VIN externally to begin [car unlock service](unlockcardoor.html title="Unlock Car Door Service") or key replacement.
The VIN is broken into specific segments, each with its own meaning. The first three digits are the World Manufacturer Identifier (WMI). Digits 4 to 8 describe the vehicle attributes, such as body style, engine type, and transmission.
Digit 9 is the check digit, which verifies the integrity of the VIN. Digit 10 indicates the model year, while digit 11 reveals the manufacturing plant. The final six digits (12–17) are the production sequence number.
This code allows professionals to trace recalls, warranty issues, and even manufacture-specific key designs used in modern [keyless entry systems](whatiskeylessentry.html title="What Is Proximity Keyless Entry").
The VIN is essential for verifying the identity of the vehicle and ensuring the right key, part, or service is provided. Without it, key cutting or programming risks inaccuracy—especially when ordering keys from [online key cutting services](onlinecarkeycutting.html title="Where To Get Cut Keys Online").
It also protects against fraud and ensures compliance with insurance and DMV records. Locksmiths use it to pull the original key code for precise duplication or replacement.
Locksmiths access secure databases that link VIN numbers to factory key codes. Once we verify ownership, we use the VIN to generate the exact key cut pattern that originally came with your car.
We then cut the key using laser or mechanical machines and, if needed, program the transponder or remote. This method is extremely useful when you’ve lost all keys or when your only spare has broken. It’s part of our [mobile locksmith services](automotivelocksmith.html title="Mobile Automotive Locksmith Services") in Austin.

If you're using a third-party site to buy a replacement key, verify they are secure, reputable, and require proof of ownership before processing your request.
This can happen if the ignition cylinder has been replaced without rekeying the rest of the vehicle. In that case, a VIN-based key won’t work.
We can decode the ignition directly to cut a working key. For more info on this, visit our page about [ignition services](ignitionlocksmith.html title="Ignition Repair And Replacement Services").
Running a VIN check can give you access to a vehicle’s full history—accidents, title changes, recalls, and service records. It's useful for buying used cars and verifying ownership when ordering new keys.
You can perform a VIN check using services like the National Motor Vehicle Title Information System (NMVTIS), Carfax, or AutoCheck. Some websites offer basic VIN lookups for free.
Always double-check the VIN you enter to avoid errors when ordering a key or scheduling service. If you're using it to order a key, also confirm whether your ignition system is still OEM or has been replaced.
