Memory card slot won't properly hold card. How can I open to see slot?

I recently found the charger to my PSP street. After a long time of not taking the memory card out, I noticed that whenever I put it in the slot, I have to use a toothpick or something to hold it towards the screen to get it to read. After using this temporary solution, now I have done something where the memory stick doesn’t even “click in”. Is there any way I can disassemble to access the slot to see what’s wrong with it?
