How do I find the OEM key part number from a VIN?

What the 17 characters of a VIN tell you

Who built the vehicle, what it is, its model year, the plant and its serial number. The layout is set by federal rule, 49 CFR Part 565:

The model year is the maker's model year, not the calendar year the car was built. And the key is not on the rule's list of what a VIN must encode: no position tells you which key the car takes.

What a free VIN decoder gives you

The vehicle, not its key. NHTSA's VIN decoder, vPIC, is free and needs no account, and its data is reported by the manufacturers. It decodes a VIN into fields such as the make, model, model year, trim, body, engine and plant.

None of NHTSA's published decoded fields is a part number. The nearest one to the key is "Keyless Ignition", which says whether the car has push-button start, where the maker reports it.

Partexia goes the last step: from the VIN to the OEM key part number, with its FCC ID and frequency.

Why year, make and model are not enough

Because one model in one year is often built with more than one key. Hyundai's own service documents show it:

• By trim. For the 2022-2023 Elantra, Hyundai's service campaign notes say the SEL, Blue, N Line, N and Limited trims came with smart keys, while the SE came with remote keys.
• By equipment. Hyundai's service bulletin lists two smart key part numbers for the same Elantra N: one with remote start, one without.

Partexia's own VIN checks show the same thing, model year by model year:

Order by year and model and you can get the right key for the other car. Partexia answers by VIN.

What a superseded part number means

A superseded part number is one the maker has replaced with a newer number. In a parts bulletin Volkswagen filed with NHTSA, the new numbers are described as having "the same form, fit, and function as the superseded parts". Makers use the same word for their bulletins: a newer bulletin supersedes the old one, which is then discarded.

So when a lookup shows a newer number than the one printed on the old key, read it as a detail of that key's history, not as a licence to order a different key: the key still has to be the one for that VIN.

Partexia looks the key up by the VIN, so the number it shows is the one for that car.

How to look up the key part number, step by step

1. Read the VIN. On the dash, readable through the windshield on the driver's side, and on the certification label on the driver's door or door post.
2. Confirm the vehicle. Year, make and model from the registration or a decoder, so you know you have the right VIN.
3. Look up the key by the VIN. A dealer's parts counter does it with the maker's system, and Hyundai's own key programming starts from the VIN. Partexia does it from the camera.
4. Match the old key. The FCC ID printed on it, the number of buttons, and the kind of key: smart key, folding key or separate remote.
5. Order, then cut and program. Cutting the blade and programming the key to the car are separate steps, with your tools or at the dealer.
