Ford introduced an 80-bit encryption in late 2009 and this caused a lot of confusion as to which models it was available
on. The main question is which models use the 80 and which use the old 40 bit?
Contrary to popular belief, the SA marking on the key does NOT indicate a vehicle uses 80-bit encryption. In reality, the
SA marking indicates that the key is 80-bit compatible, but the vehicle itself could still be using 40-bit encryption.
What does it mean?
It means that Ford did in fact release SA keys equipped with an 80-bit transponder, but the reality is that the same
transponder can also be used in 40-bit vehicle, making it backward compatible with older vehicles. Consequently, if you
see an SA key it is important that you do not automatically assume it is an 80-bit type. It all depends on the vehicle, not
the key.
How do I Differentiate Between the 40 & 80 Bit?
To determine which encryption type you are dealing with, you must test pin 1 at the 4-pin IMMO connector on the key
barrel for the following conditions to determine if it is 40 or 80-bit type.
An 80-bit vehicle should provide the following values:
§
NO key in barrel:
0v
§
Key in barrel with IGN OFF: (+) 12v
§
Key in barrel with IGN ON: (+) 12v
A 40-bit vehicle should provide the following values:
§
NO key in barrel:
0v
§
Key in barrel with IGN OFF: 0v
§
Key in barrel with IGN ON: (+) 12v
