Welcome to the Forum, Drew!!
The easiest way is to just program one of the vehicles with a different key fob. If both vehicles have two fobs, just reprogram one of them again. Reprogramming erases all previously programmed fobs. Good Luck!
Just in case you need the directions -

Note: If you are programming a vehicle with multiple remotes, all of your remotes (even the ones already programmed) must be programmed under one session. If you don't, all of your current key fobs will no longer be programmed. Once you start the the relearning process, simply program both fobs within a short period of each other, under that same reprogramming. Do not re-start the learning process in between each one.
