2012 Mazda 3, Sky. I have a red flashing security warning light on when the key is removed from ignition and a beep every 2 seconds when the drivers door is opened. The beeps stop when door is closed. Also the key fobs will not work. I have followed a fob reset procedure found through a google search, not sure if the procedure is correct for this car however it did get the fobs working and the beeps stopped. Now 2 days later the beeps are back and fobs are not working again. Car starts and runs normally and security light will go out after starting.
Any help would be appreciated.
Thanks
