One goes to the mazda dealer with your car s vin and tell them what broke and ask what part you should order.
Mazda 3 door handle not working.
If your mazda 3 interior door handle is not working it s usually caused by a bad linkage to the latch.
First you will need to pry back the door panel so you can access the inside of the door.
If it locks with the fob in the car if your mazda is locking itself while the fob is in the car without it giving you a loud warning beep then something in the system is not working correctly.

Order it and install it.
It could be that the key fob has lost its charge or possibly that the receiver is acting off.
Door interior parts can be a fiddly job that scratches up your hands like you had a cat fight.
They will show you drawings you point to the part.
