all these functions deal with the link keys stored on the chip. The
default operation of BlueZ is not to store these link keys on the
Bluetooth chip itself. Have a look at the D-Bus API for BlueZ. The
methods ListBondings() and RemoveBonding() give you what you actually
need.

Thank you so much! Really appreciate it!
You have no idea how long I've been trying to solve this one! I'll take a look at D-Bus.
