Using a pair of vice grips (with protection so as not to damage chuck) grip chuck and strike vice grips with a rubber mallet, undoing chuck.

I would put the drill in reverse and hold the "chuck" and very slowly and carefully press the trigger lightly. This should bring the clamping device back where you can see it.

Likely poor battery contact, but there could be other factors.

You put the two flat sides on the end of the cap nut and lock them in a vice. You then put a wrench on the back side of the chuck which also has two flat sides. with the cap nut locked in a vise take the wrench and turn the retaining sleeve which has the two flat sides counterclockwise to break the cap nut loose. When it turns freely take the chuck out of the vise and turn the cap nut off. You then push the ribbed locking sleeve down to access an o-ring. You pull that off and it releases the locking sleeve and two roller bearings. You then pull off the retaining slv with the two flat sides and release the other two roller bearings. the chuck will then just pull off the shaft

Hope this helps

I would bring it to an authorized service center and ask for warranty - there are not individual replacement parts, all the electronics come as one assembly, and unfortunately the brushless controllers are very expensive making the tool not worth repairing.

Replace battery. Ni-cad batteries have a life cycle, yours is the end of its life. Upgrade to lithium, battery if your tool will accept it. cost more delivers more in performance than the price difference. I once had nicad tools and disposed of all them and went to better battery..

Grit or dirt has jammed the space inside, where the spring is.
If it overheated, plastic may have melted / warped, causing a jam.
Spring could have shifted out of its bed, also jamming the works.

Tap the top with a piece of wood or soft mallet.
Use a heat-gun on LOW setting or at distance to warm the collar.

Alternately, drill needs strip-down to remove and access the spring-loaded chuck.
