In the late 1990s and 2000s, Ford and Mazda (which had a partnership) used a common immobilizer system in many vehicles — particularly the and similar Mazda systems. When a key was lost or a new key needed programming, the vehicle's immobilizer would generate a "outcode" (also called a challenge code, typically 6 or 8 digits).

The outcode is passed through a (a mathematical formula) to produce the incode. This algorithm is not public – it was created by the immobilizer manufacturers (often Texas Instruments or MegaMOS in these cars). ford mazda outcode incode calculator english

: This is the "answer" or authorization code required by the vehicle to proceed. It is calculated based on the Outcode. Once entered, it "unlocks" the security layer for a limited time. How the Calculation Works
