Welcome to the forum from Oregon. As Scott said, it should be in your owner's manual, unless those turds stole that too.

It’s definitely in the manual. I remember to enter the mode, key in ignition, pull high beam switch back. IGN forward, back, forward, back, release high beam switch.
Locks will cycle saying your in program mode. You have a short time to make changes. Then they will cycle again exiting program mode. If you still have questions, I’ll get a pic of my manual they should be the same when I get home (I work nights) good luck!
