The battery is roughly 13 months old. I will try throwing it on the trickle charger. The car runs great with no issues after the incident it's just weird and can't figure out what is causing the issue. When I bought the car in 2016 we traveled 5 hours to pick it up in Rolla Missouri. The car has 120,xxx miles never had issues with it except for having to change the conductor plate and once every so often I will turn the key and nothing will happen, but on the second or third try it Gore's right up. I replaced the rcm with one from needs wings, also replaced the crank sensor with the bosch and can sensor. I also changed the the ignition switch last year but the car had already done the random starting up with not key twice. I also bought a new key through needs wings, but that was four years ago. I wanted to repair or replace the skreem modual and skreem antenna, but there is very little information out there about the skreem module and what fails on them or how to repair or replace anything within the module. Thanks to the whole fca discontinuing the module and not be able to use Mercedes modules it made the price ridiculously high and left crossfire owners not many options.

 

The screem can be repaired by SOS Diagnostics. They also make spare keys.

 

Yes, failure in the aftermarket module (likely) or bad wiring job in the installation of the module (possible, but not likely).

The aftermarket electronics are integreted with the SKREEM and ignition switch wiring, I'd blame this all on the aftermarket item.

I've been a member here for eleven years. I've NEVER heard of a SKREEM doing this.
Besides, the whole "I step on the brake and it dies" thing describes the performance of a remote-start when you hit the brake BEFORE you put the key in and turn the key to "ON". That is the anti-theft feature built into the remote start kit that prevents some jerk from stealing your car.

I am sure that the SKREEM wiring/design does not make a "phantom start" due to a bad skreem a possibility.

You might drop the underdash again and take photos of the entire area, and post them here.

 

There is absolutely no module by itself in the car that if it was going bad would engage the starter, pass a matching security code to the ECU, and have the engine run.

No Crossfire engine will run without the KEY-SKREEM-ECU communications!

The more recent exception, that does not apply in this situation, is an ECU modified by a third party like Precision ECU to eliminate the SKREEM. Even then there is no module that would both engage the starter and turn on the ignition power so the engine would run.
