Key would not open or start car. Replaced 10 yr old battery for car. Key will not turn engine over. Tested battery in key and it stated it was a good battery. Used second key for car and it will turn over engine. Need to know why the first key has stopped working.

The key in question will need to be paired to the car. See your friendly local MBZ service provider and have a great day.
