When i put the key in the ignition the dash lights don't light up

Your battery may have a dead cell. It will still have 12+ volts and will run your dash lights and buzzer, but when a real load is requested, it doesn't have it to offer. The problem is quite common. The only way to know is to use a battery tester.

sounds like a bad light switch....and that dash lights stay on drains battery

Try this Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. Your theft light should go out. As long as the light is on your fuel system is disabled. If that dont work try a different key do the same thing. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

most probable cause could be a faulty ignition switch. Does the lights on the dash come on when you turn the key to the on position ? Do they turn off when you turn the car to the start and are about to crank the engine ? If that does not happen you will have to replace the Ignition switch. They don't have a fuse for the dash lights.

Well, you can sometime catch the code again. Pt the key in the ignition and turn till the dash light come on (dont Start) then press and the Lock button while keeping the Lock button Pressed and turn the dash light off and put the key with the lock button Press for 10 second afterwards. If not successful first time try again. This should do it.
