You have to figure out what's wrong with it, first. Chances are, you'll have to replace it (or a part of it). How you go about it depends on which part you're replacing.
Its a dealership part
If the button doesn't move at all on the shift knob it is this. There is a small white part attached to button linkage with a bearing at the top of it. Odds are it is broken and it won't push in because that bearing tip broke of and is jammed in the button assembly of the shift knob.. take off the shift knob and buy the replacement part after prying out the rest of that part from the stick.
It is the part that connects the handle the driver moves with the linkage on/inside the transmission.

part is between 75 and 150 depending on quality & source. and an hour to install about 100. so about 200 to 250 for a repair facility
Expect to pay between $300 and $500 depending on whether its an original Chrysler part or an aftermarket replacement.
This could mean that your shiftier linkage has bent somehow. You need to replace the linkage as bending it back will only result in having a weakened part. If may also mean that your fluid level is low in the transmission and it won't shift into a specific gear. Add fluid as necessary.
My 05 started to make a metal to metal sound turns out the rubber join on the linkage bar wore out,the part it s About $90 to change it you'll have to lift it on jacks with enough clearance to work under, after that its just a matter of using a wrench to loosen it up.good luck
The cable is part of the shift indicator assy . Must be replaced as a unit
