I am sorry your having this problem
make sure both battery cables are clean and tight if they are then the odds are what is going on is the battery is weak or dead or low on amps or a bad cell in it
the key release needs 12 volts to release the key
when it will not release the key usually the battery is bad
the best action to take is to remove the battery and have your local parts store test the battery for volts and amps and for bad cells the odds are just the battery is bad causing all these problems
the battery is located inside the vehicle just behind the passenger seat area under this cover as seen in this picture
just make sure the battery and battery compartment are not filled with water
if it is remove the battery and dry out the battery compartment and change the battery
try a torx style bit ?
these should be a torx style pattern in the screw
how are you making out ?
