You joke but my old FJ Cruiser requires you to turn the key to accessory, turn it off, turn the key back to accessory, open and close the door three times, turn the key back off, turn the key to accessory while holding the odometer reset button for 5 seconds and then it will enter pairing mode for the remote fob.
It made me feel the same joy as pressing the option on my Android phone 5 times to enter development mode back in the mid 2010s but it gets old quick.
