ELI5: How come you can use a password, or a combination to a lock, every single day or even multiple times a day and then one day out of the blue you just forget it?

You've probably transitioned to muscle memory. You no longer consciously enter the pin or twist the combination lock to a specific number, you've just got a sense of the pattern to move your hand on the pin, or how long to turn the dial on the combination lock. Once you try to transition back to conscious memory, you realize that you've forgotten the information, since you've relied on muscle memory for so long.
