The key is stuck in the ignition (as i type this), i beleive the problem lies in the shifter, because when the button on the shifter is pressed down the key will release, what do i need to replace??

WHERE YOUR SHIFTER IS YOU WILL HAVE TO TAKE IT APART ..MAYBE THE RUBBER BOOT IS IT THE WAY,OR THE SHIFT LOCK SELINOID WHENT BAD

The parking brake might not be dis engagin the shift knob, you can do it manually before you can fix it by entering a key or a flat head screw driver on the little port (looks like it wont open but it will) next to the shifter on the upper right hand corner I beleive it is. Just press it down by introducing the screw driver and this should dis engage the shiftter

I have worked on several vehicles with this same problem and each one was a relatively simple repair with no parts involved, first off the shift interlock has nothing to do with it and will not prevent your vehicle from going into park, it is designed to work ONLY when coming out of park. The problem your having depends on the type of shifter handle your vehicle has, if the release lever is on the bottom and you have to push up with your fingers to release it, then the problem is...there is a rubber type cover that surrounds the release button, after time it becomes distorted and bunches up preventing the shifter from fully engaging in the park position (even though it appears the vehicle is going into park)if your careful you can work the rubber cover out and your problem is fixed. If your shifter button is on the side and pressed with your thumb the cable needs to be adjusted, this cables only purpose is to prevent key removal except when in park and is easily adjusted, with the center council removed, if you look at the front of the shifter base you will see 2 cables that snap into the shifter frame, the larger one is the gear selector cable, the smaller one runs up to the steering column and operates the mechanism that prevents key removal, where the cable snaps into the shifter frame is where the adjustment is done and is identical to a kick-down cable used on older vehicles with automatic transmissions, right where it snaps into the frame there will be a button you can press down releasing a spring loaded adjustment arm, make sure you first mark the arm for reference then press down the button and adjust it a little either way until it functions properly, hope this helps and good luck

while in park, press shifter firmly even farther above park. Hold shifter and turn key.
The linkage may need adjusting. If this does not help the situation, then the pins inside the ignition are not getting pressed down because key is getting worn. You can try to tap around the ignition lightly with hammer to shake the pins loose.

u probally need to change the shift assmebly , i had a problem like this with my x-type , where as the key would not come out , it was because there is some kind of button down in the shifter that gets pressed when the car is pushed in park , so probaly something broke in ur shifter , and that button is not getttin pressed to release the key .

I had that same problem. There is a gear shift lock button to the right of the gear shifter that has to be pressed down before you can unlock the gear shifter and the key.
