FCC ID, OEM Reference Number and Fitment: How to Match a Replacement Key
Fitment guide
FCC ID, OEM reference number and fitment: how to match a replacement key.
Two car keys can look almost identical and still fail to work with the same vehicle. Compatibility depends on the electronics, chip, frequency, button layout, blade style and vehicle configuration. That is why Car Keys Wholesale uses multiple references instead of relying on broad keywords.
What is an FCC ID?
The FCC ID identifies the radio transmitter approval for many remote key fobs and smart keys. It is commonly printed on the case, inside the shell, or on the original remote label. When a product page lists an FCC ID, use it as a compatibility reference for the remote electronics.
What is an OEM reference number?
An OEM reference number points to a vehicle-manufacturer part reference that a replacement product may be compatible with. On this site, it is not a claim that the item is OEM or vehicle-manufacturer-branded. It is a reference used to help match a Keys4Less aftermarket replacement to the correct application.
Why button layout matters
Button count and icons matter because remotes are often built for specific vehicle features. A four-button remote and a five-button remote may share a shell style but support different functions. Always compare the visible buttons before buying.
Why vehicle year ranges can overlap
Vehicle generations, trim levels and mid-year changes can create overlap. A product might fit some vehicles within a year range and not others. If your current remote has an FCC ID or reference number, use that detail alongside year, make and model.
What if you do not have the old key?
If the original key is lost, start with the VIN, vehicle year, make and model, then verify with a qualified locksmith or dealer when programming is required. Some vehicles require proof of ownership and secure programming access before a replacement can be activated.
