Hi,
The way the lockers work is that by the entrance to each of these rides, there is a bank of lockers. They are free for the first hour and 40 minutes (more than enough time to wait and ride). The lockers are set up in rows, and in the middle of each set there is an electronic screen that has instructions how to use them. What you do is use the touch screen to say you want to rent a locker. It then asks you to put a thumb on the fingerprint reader right below the screen. If it reads the print adequately, it then asks you to put the same thumb on again to confirm. If it gets the two good readings, it then tells you what number locker you have. That locker has a little light (some of them red, some green) that is blinking when it is unlocked for you. You open the locker, put your stuff in, close it, and push the lighted button to lock it. Remember your locker number!!! Then you go ride the ride. When you come back for your stuff, you go back to the same screen, and use the touch screen again, but this time you tell it you need to open your locker to retrieve your things. It will ask you the locker number, you punch it in, and then it will ask you to put the same thumb you used to rent the locker onto the fingerprint reader. If it matches, which it should, your locker is then automatically unlocked and you can retrieve your stuff. It sounds more complicated than it is, but after the first time it literally took less than a minute. The only delays were when people in front of me at the screen either couldn't figure it out (I ended up explaining it several times) or had trouble getting their fingerprints to register. I think most of the time they were pushing too hard or moving their thumb or something. If you forget your number or have other problems, there is an attendant there to help. We stayed onsite, so we had Express pass with our room keys, and we rode those four rides over and over again, so we used it a lot! A little inconvenient, but not a big deal. Have fun~
