I have tried all protocol calls on resetting the computer by turning on ignition and turning it off 3 times to no avail. It has no spark fuel is okay. Heard several stories it has to do with security code. But has tried to reset it. Still has not worked. Bought new cam sensors and crankshaft sensor no luck. Is there any input you could help with regarding this problem?

Hello,

Yes, that code shows the car went into lock mode, this usually happens when the starting operation is carried out consecutively for five or more times with an unregistered ignition key or fault key. Did this just happen clear out of the blue? The reset you tried sounds like the the key on and off with the 5 second wait, the time is sensitive on that. Is there a chance that your key got damaged? Or has the ignition switch been hit? Here is the reset steps and I attached the antenna pic for it which is right the surrounding the key tumbler. If this was hit and is out of position the security system wont work and it wouldn't reset. Look around that area to make sure nothing is out of whack as well.
Let me know what you see if anything.

Reset steps:
Turn ignition switch "off".
Turn ignition switch "on" with registered key. (Do not start engine.) Wait 5 seconds.
Return the key to "off" position.
Repeat steps 2 and 3 twice (total of three cycles).
Start the engine.
