Ford Fusion hybrid 2015 smart key system, VVDI Key Tool Plus can’t program 2 keys from different sources, 4 keys are written in memory. How much the maximum can be or what is the problem? 1st key china, a 2nd original used. Program both, and all good, but in the end, the match failed. I think 4 in memory maximum.
Program both keys as AKL. (erase all keys and add two keys)
Backup D-FLASH and P-FLASH data>>Lost All Key>>Load D-FLASH data>>Erase all keys>>Add new keys (Maximum: 4)
When Key Tool Plus asks you to select the region (China market/Asia Region), don’t be confused, just try if the device can communicate with the vehicle.
I solved the problem by deleting the keys. 4 keys maximum number.
