Hi! I am having a problem with my 2007 RX350 from yesterday. I have only one key and one after market remote starter. When I try to start the car with the key, the car's security alarm/ panic alarm goes on and it does not start. The key still closes and opens the doors. On the other hand, I can still start the car with my after market remote starter, and after that when I put key into ignition, and turn in into on position, the car starts panicing again but I can still drive it with panic alarm. I talked with lexus roadside assistance guys, their suggestions are working. Can anyone please help? Thanks in advance!
