What deactivates hotel key cards?

If you dropped your card on a hard surface it might have gotten nicked. Scratches, crusted cracker-crumb bits and folds might make it harder for the card to be read. Cards left in the hot sun, rubbed by beach sand in a pocket or stepped on by a dog might look just fine but may have lost the ability to open your door.
