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.
Start by removing the two screws that secure the panel to the door.
Just take your time.
Door interior parts can be a fiddly job that scratches up your hands like you had a cat fight.
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.

My manual door lock is not working then i went my power hello sir i have a new mazda 3 2010 and i just upgrade it with power doors and keyless entry and its works but my problem now is my manual door lock is not working then i went back to the shop who in.
It could be that the key fob has lost its charge or possibly that the receiver is acting off.
The panel can only be removed when the door is opened but you can pry it back enough to get some working room with the door closed if it is stuck shut.
They will show you drawings you point to the part.
