You don't without breaking the door panel.
disconnect the battery and try to open manually from inside
Take inner door panel off and look inside the door and you will probably find a rod off the outside door handle.
as like the key wont turn or the door is just stuck? if so id try a lock smith cuz it might have to be drilled out. if the door is stuck just tug it hard sometimes integra doors bend easily so they dont close right
I suspect the rod that opens the door has come loose or broken off the door handle and is keeping the window from coming down. Take the inside door panel off and check. If needed just replace the door handle.
You have to pull the inside door panel off. Once removed, look for the door latch mechanism and pry it with a screwdriver. This will release the door.
Nobody knows.. Or they wont tell you... Have to take it to the mazda dealer...
If it`s a "pull up to open" handle, most likely the rods jumped out of their place. Can be solved by anyone by placing back the rods with your own hand after you take the door panel down.
remove the few screws you can see then lift up on the door panel. if it wont move look harder for more screws the panel should pop right up.
On my '02' Expedition the rear actuator went up leaving the door stuck in the locked position, the key nor the key fob would unlock the door. I had to get a locksmith to unlock the door to get the rear panel off then take it in to get the actuator replaced. If this is your problem then if you get a locksmith to unlock the rear door, make sure you take the panel off so you can unlock it from inside.
Go in from another door and open it from the inside.
take seats out so that you can gain access to the door panel. remove it and unlock. or remove fuse. not sure if it has one though.
Use the key to open the door.
