How can I remove my chuck?

Hi, Currently need my drill but my keyless chuck has jammed up. It's a Bosch psb 750-2 RPE. I managed to open the chuck part way and see a small round hole inside, unfortunatly it's not an allen key. I know you can buy a spare chuck for it so I presume it comes off some how. It has a split O ring on top to the chick along with a but nut. I have taken the o ring off but turning the nut just seems to open and close the jaws.

Thanks in advance for any help

I took it to a repair shop. He just put a massive allen key in, like 12 " by 4". The small round thing in the bottom wasn't a screw at all. The repair guy held it in his left hand and hit the allen key with an axe handle in his right hand. So in other words there is no locking screw inside this chuck for this model drill. Hope this helps anyone else in the future.
PS As you look at the drill from the front ( bit/chuck end ) the chuck screws on clockwise and off anticlockwise.
