My key FOB battery in my 2009 RAV4 died and the car battery also died while being parked for about 4 months. I charged my car battery but can't get the FOB battery for a couple of weeks (in Mexico). I started my car by holding the FOB close to the Start button and verified I could move the car. However, the Anti Theft light continues to flash even after I've shut the car down. I'm afraid it will run mu car battery down. Any suggestions?
