Here is the engineer solution to the Key Pro M8 automotive key programmer failed to program old Ford PATS key problem.
I tried to make new keys for Expedition 2001. I have MVP Pro clone (Key Pro M8), but I cannot see “key programmed” function in the menu list.

How to program old Ford PATS key with the M8 Key Pro auto key programmer?
KEY PROGRAMMING > 98 1/4 MY
a. Clear ALL Fault codes before programming
b. Up to 8 keys can be programmed into the PATS system
c. If programming is unsuccessful,the PATS LED will flash when the key is inserted
d. Newer systems are only supplied with 2 keys. Both keys are required to program further slave keys.
e. Master key can only be programmed using the 2 PATS keys (A and B) with the FDS2000 or the AD PROGRAMMING SYSTEM system
f. In some cases the vehicle doors must be closed to perform the re-programming sequence.
Further slaves can be added without any specialist equipment as follows:
1. Insert key A, and turn to Position 2.
2. Turn back to Position 0, and remove key A.
3. Insert key B, and turn to Position 2.
4. Turn back to Position 0, and remove key B.
5. Insert the new slave key and turn to Position 2.
6. Remove new key. Key is now programmed.
7. Procedure can be repeated after 20 seconds, for up to 8 slave keys.
