I took out the batteries of the remote control to my 99 a4 and then when i tried opening the doors after they wouldnt. i read some reviews on how to reprogram the remote but i only have one key to the car. Is there a way that i make my remore control work even if i dotn have another key?

 

You only need the switchblade factory key and the car. Put your key in the door and turn it as to unlock it. Hold it in place until the windows start to drop while also pressing the unlock button on the remote. Should do the trick! Good Luck!
