Keyless chuck jammed
SOURCE: Can't get the keyless chuck off cordless Makita 6095D drill.
If this is a newer tool it is probably a Torx drive screw usually a T20. The screw is LH thread and after removing it you will need to put some screws back in tool to remove the chuck. First shift the gear selector to the low setting and the clutch to the drill only. Next get a bent handle allen wrench about the capacity of the chuck install the short end of wrench in chuck and tighten. Put the chuck on a block or wood or a workbench to support is and turn the wrench to about a 30 degree angle in the counterclockwise position. The chuck has standard threads so you want to hit the wrench with a hammer to loosen it. This might take a few tries but it will work. Good luck
SOURCE: Bit stuck in Bosch PS20 keyless chuck
These units have only been out for a short while and most are on warranty. Take it to a Bosch Service center in your area and they will replace the front of the unit. Unfortunatly this is a problem with this type of unit. The bit will deform slightly from the impacting action and lock itself in the chuck.

if chuck is wide open ,look down inside there should be an allen screw or bolt at the bottom of the chuck it should undo anti clocwise and the chuck comes off
SOURCE: Chuck on Drill not moving
I had the exact same problem with a ryobi 18v hammer drill. I and three other guys tried unlocking the keyless chuck. none of us had any luck after a good ten minutes of trying. I went home, put on a pair of leather "WORKER" gloves. NOT the nice expensive ones my girlfriend bought me!
I held a strong firm grip on the collar and with the other hand I did the same on the chuck. Gave it a strong twist and on my first attempt it unlocked :D
It's surprising what a difference a pair of gloves can do.
Also if anyone else has a similar problem, try and use suede leather gloves. They have alot more grip than plain flush leather.
Hope I have been off help.

It really depends on the model. Here is a general description of how to remove most regular keyed and keyless chucks from corded and cordless drills:
Some chucks have a Left Handed screw that secures them to the spindle so they do not come loose. You can look into the chuck with a flashlight and see if there is a chuck screw. (It may be a torx head, flat head, or philips head) You will need to remove this screw first before doing anything else. Sometimes there is loc-tite applied to the screw so it may be stubborn and sometimes you will strip the screw head. Remeber that the old saying lefty-loosey, righty-tighty does not apply here. Left is actually tightening a left hand thread, so you want to turn it right to loosen. I know, it will feel weird but thats the way to loosen it. You may have to apply some heat to the screw in order to get that loc-tite to break. A pencil torch works great. If you strip the head out you will have to use a drill press and drill the screw head off.
After removing the screw you can remove the chuck.
To remove the chuck, the easiest way is to use a hex socket bit and an impact wrench. Put the hex bit in the chuck, and depending on the condition of the jaws, tighten the jaws as much as possible to the hex bit. Put the impact in reverse and bump it until the chuck is loosened. If you do not have access to an impact wrench you will need to put a hex key with a long arm into the chuck and tighten it then place the drill on the edge of your bench and give it a good whack with a 3lb hammer. It may not come off immediately so you may have to reset and do this a couple of times. Not the most effective way to remove a chuck, especially if one of the jaws is missing, but that is what most manufacturers tell you to do. I myself cut the collar off with a die grinder and then use a pipe wrench on the body of the chuck applying constant pressure while heating the chuck body with a torch. Works every time. Heat is our friend on stubborn chucks. Good luck, any questions please post.
