A510 Unable to open battery compartment to replace

BATTERY COMPARTMENT

The battery isn't discharged, I'm able to take photos. But I haven't used the camera for probably a year until now and I want to replace the battery just in case it's near end of life. I can slide the button of the battery compartment door, but the compartment doesn't open. I expected it to just sortof pop open. Is there something else I need to do to get it to open?

Thanks for your help,

Burnunit,

Thanks for your reply.
I decided to hold off on the DeOxit, unless and until none of the other suggestions provide a solution.

Are you sliding the cover latch all the way to the end of the slot before trying to open the battery door?
