You can change the battery in your Mini Cooper by releasing the hood lock located on the bottom portion of the dashboard. The key to unlock the battery cover should be on the side of the battery cover.

Check fuses as the battery change should not initiate a "No Start" condition.
u shud take it out and change it.
