No Crank, No Start Diagnosis - 2005 BMW X5 2F45

This BMW had a code in the DME(Engine Control Module) of 2F45 and was towed in for a no crank, no start issue. After chasing my tail and checking some wiring to the DME and CAS(Immobilizer) Module I ended up seeing something that turned out to be quite a simple and silly cause of the issue!

If you have this code on your BMW it could also be caused by a faulty key, faulty antenna on the ignition switch, or even a bad immobilizer or shorted wire. Luckily this one was something simple!
