Most people don't find Channel Lock to be stupid. The Channel Lock feature routes the Ch+/-, digits, and OK keys to the cable box, even when the remote is in TV device mode. The feature can be disabled, but most people actually want the Ch+/- keys to always go to the cable box.
So instead, do a keymove-- assign a function code to a key. In UEI remotes, when a key is pressed, the remote looks to see if a keymove has been defined, then if a macro has been defined, then for Channel Lock or Volume Punch Through, and finally the basic function assigned to the key. So the keymove gets priority.
Press Setup until 2 blinks
Enter 994 (2 blinks)
Enter 24885 (this is the EFC for OK/Select in 10650)
should get 2 blinks
Now with Channel Lock enabled, the Ch+/- keys will still control the cable, and when in TV mode, OK/Select will go to the TV.
