How do you program a 2009 mazda 6 push button start remote so i dont need to use the key no more?

Sound like the computer has lost its memory.
Probably going to need specialist advoce on this one

How do reset the computer or BCM on an 09 Mazda 6

The fob may need to be reprommed to the car. Do the following:

Grab your working remote. Push the LOCK button five times, allowing exactly two seconds to pass between each press of the LOCK button. Insert the ignition key and turn it to RUN. Push and hold UNLOCK on the working remote for 6 seconds. Push and hold PANIC for one second while continuing to hold UNLOCK. Release both buttons at the same time.
Push any button on the remote to program it. Then push any button on the remote that was already programmed. It has to be reprogrammed. The remote is now programmed to the vehicle. Turn the key to OFF.

You need to have the system reset by the dealer.

I had the same thing happen when I replaced my battery on my 2006 mazda 6. The program has to be re-programed and it is very simple. Simply push the window button down until window rolls all the way down, then pull up and roll window back up, but dont let go fo the window button for 3-5 seconds after window rolls back up all the way. This resets the program. Do it to both driver and passender side windows and do it with the key in the on position, but not with the motor started. Hope this helps ya

Good luck and this should work.
