Hello

I have a 2009 Mazda 3 MPS BL. I have a few issues happening with my car now that the battery had died and I have replaced the battery.

1. I have recently changed the battery in the car as the other one died. I tried to start up my Mazda using the keyless key (which always used to work) and is now working. When I push in the clutch to start, it does not even recognise the keyless key (for both of my keys). I tried to put the key straight into the ignition but the push start button illuminated red. The central locking does not work either. I have a 3rd key which is the one I got when I purchased the car 7 years ago, although that does not have the keyless cover. The key works and starts my car up just fine.

2. Drivers window doesn't automatically go down. I have to hold the button for the window to come all the way down (this never use to be the case).

3. The Revs stays on 1 when I turn my car off instead of going back to 0.

4. The radio doesn't work. Matter of fact, none of the buttons to the radio/ CD play/ AUX/ Bluetooth etc work. There is nothing on the top part of the screen...


I would love your help with any of the above problems.

Thanks!

 

1): 1st step would be to disconnect the battery, wait 5 minutes. Make sure all the doors are closed & lights off, reconnect battery and see what happens.

2): Re window, hold the button all the way down, then hold it all the way up & wait 2 seconds before releasing switch.

3):Re revs, hope fully battery disconnect will fix it.

4): check room fuse and both audio fuses.

 

Did you fix this? I’m the same
