Audi Key Fob Flashing Red Light

Red light on key fob rapid flashes while the button is pressed.

Audi key fob flashing red light. The red light kept blinking. Everytime i try to use the remote not only it does not open the car but the alarm goes off and i have to lock and unlock with the key for the alarm to stop. I have a 1999 audi a6 avant quattro and rewcently i lost the use of my remote key lock from the fob. Changed battery no difference.

And then the key started flashing red. Any thoughts on what this might be. I also noticed that now my dome light does not come on when i come near the car. I have a 2004 audi a8l and the key fob is not working.

When i push any of the buttons on the fob i get the flashing red light. I ve been using the key to manually lock and unlock the car for the last week. I only have one fob so i can t determine where the issue is. My key fob is not working at all with my car.

The car is currently locked. I replaced the battery of my only master key and the red light keeps flashing. I replaced the battery and still nothing. When the engine is running using the key fob to open the trunk does not work.

Red blinking light on 06 audi a4 key fob audi 2006 q7 question. Jump to latest follow 1 4 of 4 posts. Fob indicator light hazard warning light drained. I looked up the sync where you hold top or bottom button for 2 sec s and then either un or lock the car with key.

Is there anything i can check. Quasar single channel remote key fobs has stopped working. I was able to get the trunk open using the key but this did not reset anything. Other similar remotes the light is constant.

I followed the instructions on page 31 to no avail.
