Mazda Repair Questions? Ask Mechanics for Answers ASAP
Welcome I'm Chris aka Moose
If the remote does not work, and the key will turn but not unlock it, then the door lock actuator has no power from a dead battery most likely. Scotch the wheels, raise the front of the ground. Connect jumper cables or a charger to the largest wire on the starter or alternator. The the other to chassis ground. Now power the vehicle with a charger or jump start to see if the door now unlocks so you can then enter and open the hood.
