The ignition switch is an assembly where you insert the key to start the car. The electrical portion is removable, so you can replace if contacts get worn out. Look on youtube for people that replace the electrical portion of the ignition switch on accords. There are several videos out there on this topic for Hondas.

PCB repair
I had similar problem.....took radio unit out of the dashboard....removed oxidation and re-soldered cold joints in PCB....and it is working well
Hello, I'm new to the forum but looking for some help. I have a 2005 Honda Accord LX 2.4 AT and the radio and clock turn on overnight by itself and kills the battery over night. It seems/act as though the key is left on the accessory position of the ignition switch but the key is out when this happens. I thought it may have been the ignition switch, had it changed but but that wasn't the problem.
Is there a relay that turns on the accessory position of the ignition switch?
Thank you, poolman

OK, so I pulled out the radio and tested the yel/red wire for voltage with the radio removed. Didn't show any voltage at the yel/red wire with the car off and when the key turned to acc. it had voltage. Thus I'm pretty confident that it is the radio causing my problem. I put in a used radio and the problem seems to be fixed.
Is there somewhere I can send the original radio to be repaired? Thanks for all the help.

The easiest and cheapest way to get a kill switch is to determine the fuse you need to pull.
You can purchase a fused kill switch that plugs into the fuse. No splicing and plug and play. Search ebay with the line below to see what I'm talking about.

Just make sure you get the fuse adapter for the correct pin size. Im not sure if your accord uses mini or micro fuses.
You could also make this as well. It is a fuse connector where you put a fuse and a kill switch into the wire loop.

Thank you so much for the reply. It is really helpful. I think a friend will come over tomorrow and take my battery and charge it. It would seem that we need to determine what the culprit is, though. He may have a multimeter. We'll see.
