04 CS sometimes doesnt start.....
 

Hello everyone. I have an 04 CS and its now having issues sometimes with starting. I put the key, press the brake and try to turn the car and it doesnt start/turn over/crank, no lights and resets the seat memory, radio and clock, I then take the key outand re-instert and it starts. Could someone help me. Is this an ignition, battery orsomeswitch issue? Thanks in advance.
