Car key

I have a 2000 Ford escort. I got a duplicate key made at the dealership. After using that duplicate key none of the other keys work. How is this possible?
or is it coincidental to another problem?

When you say that none of the other keys work, do you mean they won’t turn in the ignition or door, or that they will turn, but the car will only start with the new key?

Thanks for the question
The car will only start with the new key
