When I tried to unlock the doors with my keys, both of them did not work. I tried the re-programming method and each step worked up until I had to press the buttons twice on the remote. There was no reaction from the car on either key. I have also tried the method where I turn the key 4 times along with opening the door 4 times to see if the doors would unlock/lock, trunk would open, and car would honk and it worked. I just got new batteries for each one and it still does not work. The red light still blinks when the doors are locked and closed. Do I need to buy a new remote or can I just go to a Mazda dealership and have them reprogram the remote? Can anyone help me fix this problem?
