I changed the ignition switch thinking i could do it myself thru tutorials now the car wont start. The clocks on and when i put the key in it makes a noise. I even tried putting the old one back in. It does nothing no lights, radio, windows wont roll up or down. Its a 99 accord lx. What could be wrong?

 

Check fuses in under hood fuse box. You may have blown a main fuse w/ previous ignition switch.

good luck
