Could be: Power issue, crankshaft sensor, BCM/PCM,

Power issue, BCM/PCM

Security completly disable the fuel injectors so do not cause rought idle.

THAT could be security related.
I suspect Power issue or bcm/pcm.

Power issue or starter or shift interlock.

Actually, I got that issue when the ignition switch failed.
Power issue or BCM.
My first step would be to check for proper power, a voltmeter can tell alot, just back probe the fuses, look for abnormal voltage. This is how I identified my bad switch issue. Black probe to any ground (bare metal on the car, like a bolt) and probe the fuses... if you see a big difference between the fuse voltage and the battery voltage (battery should be around 12.5V, at <=11V at the fuse I would be very concerned) then it's sign that there is a bad contact, which would be a relay or a switch. The ignition switch is what switch almost all the current in the car. It have probably 2 ignitions wire and 1 accessory wire, for a total of 3 circuits.
Those 3 circuits are "separated", which explain why you might see some stuff working, and some other do not work.
A bad contact often cause intermittant issues.
My next guess would be oxidation at the BCM and PCM.
The PCM is located under the dash, driver side, on the car side. You can't miss the module.
The bcm is behind the glove box. Still lots of wires.
If you see green or white powder, that's oxidation. Beware that if you want to disconnect the connectors, it's hightly advised to remove the battery negative before doing it. Those computers are pricey, you don't want to kill one due to the power that flow in the wrong way.
