I posted a thread a few days ago that my ignition switch was causing a parasitic battery drain, I’m now looking to replace it. During troubleshooting I unplugged the switch, which stopped the drain. I put the car back together so I could move it around and not surprisingly since I unplugged it, it will not turn on or start unless I remove the dummy key and insert the real key. I’m guessing that when I replace it with a new part, it will behave similarly and coding will be required to reestablish the keyless start.

Does anyone know the process to get this working again after replacement? Thinking it may be coding the key or the ignition switch/front end electronics control unit?

I poked around with my Thinkdiag Magic and didn’t see anything immediately obvious. Hopefully I can avoid a dealer visit.

 

I don't believe the switch is coded
