Boot Wont Open

Hi new to this forum so hope you can help. A few questions regarding my boot.

I'd been having problems for while with the central locking fuse keep blowing. NOt sure if this was realted but the fuse has stopped blowing but my boot now wont open.

Is the boot lock on the same fuse as the central locking?

Is there a emergency release in the car?

I've only ever had ignitioon key and this doesn't seem to fit in the boot, does the boot have a seperate key?

I tried removing the shell form the inside, but only managed to get the bottom off. Is it easy to remove the top shell exposing the lock?

Thanks in advance ;)
