Ok if you read my last thread my car is still losing coolant but now new problems have surfaced my key which is an ilco copy master will not turn in the driver side door it works everywhere else and also my driver side door will not lock when I lock any other door plz help at my wits end here

 

Seems like the driver side door has broken door lock actuator.
Maybe the passenger side too.

 

Have you tried some dry lube for the keyhole? I also believe your door lock actuator is bad if your door does not lock or unlock with the lock/unlock button inside your GS.

 

I agree with trying lube for the key hole. Use wd40, pb blaster or whatever. Spray on your key and in the hole. Insert key and try turning your key both directions. Hopefully it'll loosen up.
