To access this, you can find the small release button or latch located behind the fob (check the user manual for details). Pressing this can allow you to open the fob, and then gain access to an actual key that you can use to unlock your car.

Then, replace the new battery in the same orientation that the previous one was inserted (the positive side should face upwards towards the buttons). Test the lock/unlock function, and start the functions of your fob after reassembling it to ensure the battery has been installed correctly.
