A broken or faulty Mazda 6 door handle can be replaced at home to save money or gain mechanical experience. Unlike projects involving the transmission or engine, door handle installation is a beginner project that doesn't put you at major financial risk. Door handle kits can be purchased from an authorised Mazda dealer, online and at some retail automotive shops. Installation can be completed in an hour and requires only basic mechanical skills.

Things you need
- Tape measure
- Crescent wrench
- Socket set
- Philips head screwdriver
- Flat head screwdriver
Open the driver's side door. Put the key in the ignition and turn it one click forward to start the electrical system. Roll the window down 8.3 inches; use a tape measure or yardstick to ensure accuracy. Push the hood button to release the hood latch, then remove the key from the ignition and exit the car.
Open the bonnet and prop it up with the stand. Remove the nut from the negative (black) battery cable using a crescent wrench. Slide the negative cable off the terminal and push it aside so that it can't shift and touch the terminal. Close the bonnet.
Pinch the weatherstrip along the upper edge of the driver's window and peel it downwards. Set it aside.
Pry the two rectangular plastic covers from inside the door using a flat head screwdriver. Remove the two screws located behind the smaller plastic cover with a Philips head screwdriver (place the screwdriver onto the screw and turn it counterclockwise.) Set the screws somewhere they won't be lost, such as the Mazda 6's cup holder.
Insert your hand into the larger hole and grasp the top of the window with your opposite hand. Carefully lift the glass upwards and out of the door. Wrap it in a sheet or blanket to protect it.
Reach inside the larger door hole and disconnect the wire from the speaker by pressing the plastic clip and pulling gently; also remove the window motor, lock actuator and mirror wires. Slide the harness free and set it aside. Remove the 12 bolts using an appropriately sized socket wrench, then remove the single screw holding the actuator in place and set the actuator aside. The door unit should now be free. Slide it outwards without catching it on the regulator and two wires (which could cause electrical damage) and set it aside.
Remove the three screws on the outer edge of the door where it latches; these screws are holding the latch in place. Pull the protector tab from the latch, then the rod, and set both aside. The outer handle on the door will now be free. Pull it from the door and discard.
Insert the new Mazda 6 handle in place of the old one. Reverse the previous steps to reassemble the door.
Reconnect the negative battery cable to the battery terminal and tighten the nut with a crescent wrench. Insert the Mazda 6's key into the ignition, turn it one click forward to start the electrical system, and use the power buttons located on the driver's side door. Make sure the wires are plugged into the correct sockets if the buttons don't work.
Tips and warnings
- Put the screws in individual plastic bags labelled with the part they belong to.
- Use penetrating oil to remove stubborn screws.
- Don't force any stubborn parts free; they may break.
- Use the correct socket size to avoid stripping the bolts.
