I've changed the battery in the key fob - why won't the car unlock?

I changed my battery in the key fob as a warning came up to change the battery. Now the car won't unlock, why is that?

You need to change the battery very quickly, otherwise it may lose the code that allows it to unlock the car.

The owner's manual may instruct you how to reset the keyfob. Otherwise, you'll need to take it to an automotive locksmith who can calibrate the fob again.
