Recent Repairs: replaced crankshaft position sensor twice.

I bought this car two years ago. It has been sitting ever since it broke down on the side of the highway.
Did a strong pull on the way to my friends house, which is a few hours away. About an hour after I did the pull the car just turned off.
I got the P0335 crankshaft position sensor “a”circuit malfunction, So I replaced the crankshaft position sensor with an aftermarket one. I then took it to a dealership where they told me I needed to use an OEM one and make sure the motor is at top dead center. Still didn’t work.
My friend recommended me to buy a new PCM from a website which was supposed to be programmed. When I received it in the mail, I tried it and got a key immobilization code. Would it be worth sending it back to the company and getting them to reprogram it? Or is there a better solution to try before before I do that?
Getting pretty upset as I don’t have much money to spare and don’t use this car. The couple mechanics, I took it to do not even want to look at it. Hopefully somebody from this form could help point me in the right direction thank you so much.

 

The pcm has to be programmed to the ecu instrument cluster and keys. I don't know if this can be done remotely.

 

I guess I’ll have to trailer it to the dealer. Thanks for the reply! I’ve also seen people use forscan and program it themselves. Not sure about the difficulty
