Ignition switch replacement

I have probably done 8 or 9 cycles since installing the ignition switch. We have been dealing with this problem for 2 years now and sometimes the relearn works on the first try, sometimes not at all and then the car will start randomly a day or two later. Also for some reason in this car the security light will never stop flashing, not after 10 minutes or even an hour, but it has been starting up until now after a few trys with the relearn. Once the car is started the security light will go off.

I have a OBD-II scanner but I think you are talking about a different scanner. Do you know where I could purchase a pass lock sensor other than a dealership?

The keyless entry does work to lock and unlock and will silence the panic alarm.

Thanks for your help again. I have to leave for work so I will look at the car again tomorrow. I think I will pull the key cylinder back out and check the connection of the passlock plug. I thought maybe I could just buy the passlock sensor since it plugs into the key cylinder.
