2009 trackmaster Rocky battery cover

Thanks to all. The base has the 2 clips on each side. They do give slightly but with a fight so I will try this again carefully. This piece is in almost a 10 condition so I have to use much care. Have a great day!

Update, pried base from end, popped off. There are 2 small posts that anchors the base, shown with the Sharpe end, however 1 post broke but does not affect the integrity of the base.
