There also is a possibility that the new battery isn't fully charged, and a small possibility that it is defective. "New" is not always the same as "good".

need to get a SDS computer scan
i bet you blew the SAM or ecu-
and if it's the ecu which means you'll have to replace 4 parts if you take them from a used car - key shifter ecu and ignition switch . They must all come from the same car because they are mated together
Changed the fuel pump relay today and it started right up.
I was thinking on putting the battery protector in there. Is it worth it? If so which one would you guys recommend?
If you are looking for a battery protector to disconnect your battery when the car is not used , get the battery brain t3 sold on Amazon
it it has a remote keyfob which connects and disconnects the battery to prevent both battery drain and vehicle theft
the t4 does not have the remote control to connect /disconnect the battery
super easy to install , it connects directly to the positive terminal on the battery

"the key wont turn turn at all. Cannot put it into ignition. Headlights are blinking. Key also wont unlock or lock from remote. Ordered new key FOB from dealer, still no luck."
"so I found the fuse and got the key to turn but now it wont start just cranks"
It would be much better to create your own thread, starting by giving full info on your car, including the market (lots of differences between USA, Europe, Japan, Middle-East, etc.), then telling us exactly what the symptoms are in detail.
