How can i get the shift cable out without the key

There should be a cable that goes from the key lock to the shifter. That cable may be broken. There should also be a lock solenoid that requires you to push on the brake pedal to get the shifter out of park.
You would need to disassemble the console to get access to the shifter and then inspect these components.

Shift cable broken or binding.
Have a trusted person try to shift it while you look at the linkage on the side of the transmission.
make sure engine is off, key on, parking brake set and all wheels are blocked in front and back (so you don't get run over)
Look for the small movement at the shifter linkage while the helper is trying to shift.
Many times, it's a small clip or mounting (cable to shift linkage) that has broken, gone missing, or twisted up.
Only do this on a flat surface with vehicle blocked in place.
Transmission shop is your next best bet if you do not feel comfortable.

You could disconnect the cable at the transaxle if you need to manually shift the trans, but you would need to disassemble the steering column to move the shift lever without unlocking the key cylinder.

i believe the cable you are you refereeing to is for the gear shift it purpose is not allow key to be removed if the car not in park and also prevents shifting out park without ignition in on postion

check the shift interlock switch. it should be right beside the brake light switch or possibly integrated in with it

its the cable part, its it steering column and hooks into igniton switch , remove covers on column.youll see a ccable going into switch take apart and see if key removes. alot of times ignition breaks inside. good luck.

shift lock located on your shifter by sticking a key or an small object into the hole to release the lock; Only used when need to shift out of gear if the battery is dead OR the brake sereniod switch goes bad and wont release the lock to the shifter when applying pressure to brake peddle to allow you to move shifter into gear. also state in owners manuel.

There's a saftey cable attached to the brake. If that breaks or gets messed up you will not be able to get it out of park. There might be a key slot in the console,insert the ignition key, & try to move the gear shift. If you can get to neutral,it'll start & you can get it to a qualified shop,without a tow bill.

Could be your shift cable adjustment. In the engine compartment move the shift cable forward ( you can do this by hand) This will move the transmission out of low gear and into park. You will probably find you can now shift into the other gears without problem but if you go into low it will stick again. You might be able to adjust it or you might have to replace the cable.
