Hello All, can anyone please help me. I have a 2000 S500 and my keys wont work. I havent driven the car for three days and its a little cold outside. Also there's a little red light under "PANIC" which lits everytime I press the button. Could this be due to low battery in the electronic key or car battery? Signal lights will flash when I point the key to the laser on the door but the ones in the headlights wouldnt and the doors or trunk wont open? Thanks and I appreciaate all coments and advice.
