Hi. Ever since i locked my keys in my car, got keys out the car wont start now.

The computer thinks it's been stolen. Try unhooking the battery for a couple of hours. Make sure all the doors are locked before you do. When you hook the battery back up, use the key to unlock the door on the passenger side first, do not open it!, then unlock the driver door with the key. Then try to start it. That worked for my girlfriend's 96 Es300, may work for yours too.
