If the starter won't crank the engine, I'm not sure why they replaced the items you mentioned. They won't help.

If the security light is on, the system is shut down. You need to take it to a dealer where the have the proper test equipment to diagnose the problem.

Hi,

Do you mean the light goes off when you turn the key and it is on with the key off?
