Locks on 2005 BMW 325i

My trunk does not open with the key, from the inside or even the external handle. Is there a fuse or is this some other problem?

Could be an actuator issue, the key should be able to open the trunk manually using the key slot and turn with "some" force. If not rears seats down or ski bag out, crawl into the space and tinker at the latch til its open and actuator replaced
