I have a 2003 rx300 and my dog chewed up the key! The actual key part of it is still good but all the buttons are destroyed. Funny thing is now it won't start. It turns over and acts like it wants to start but never actually starts. I'm thinking its it's a fuel pump issue but could it be from the key being chewed up? What issues are common for this vehicle? Someone please help?
