the tailgate unlocks with the rear doors. Are your rear doors unlocking properly ? is your car battery weak ??
The lock for the access door for the gas cap is part of the lock system for the doors. If the car doors are locked the fuel door is locked also. Unlock the doors and the fuel door is unlocked also.
So you don't lock the keys in the car.
