Help with keyless chuck

[RrogerD]

I've a chorded, keyless-chuck power drill that is stuck closed, with drill bit attached.
I am able to 'lock' the armature from turning ok, using the lock-button on the top but, the hand-grip itself simply turns whilst not opening the jaws. There is friction to the turn and a slight clicking sound but try as I might, the jaws do not open.
Any ideas?
I've tried clobbering it with a hammer; I've tried mole-grips to the armature end and a clamp to the drill but as I am unsure if this is correct, have not forced this too much.
I'm kinda stuck. Any help or ideas appreciated.
Cheers

Replace chuck I guess.
See if you can find one that will match

Easier said. How do I get the old one off? The drill is stuck inside and jaws won't open.

What about if you clamp the drill bit in a vice and then try?

Look online for your model and see if anyone has had same issue. Youtube might be worth a look.
