My 2008 Lexus IS 350 will not start, but starter goes

Customer Question
My 2008 Lexus IS...

My 2008 Lexus IS 350 will not start, but starter goes continuously. I hadn't driven the car for one week while I was away on vacation. The security light blinks even when unlocked, so I'm assuming it has something to do with immobilization system.

Mechanic's Assistant: Does the light flash, blink or stay solid? Have you tried to reset the security system?

The light flashes

Mechanic's Assistant: Are you fixing your IS 250 yourself? What have you tried so far?

Yes, trying to fix IS 350 myself. I already looked at EFI fuse and took it out for 3 minutes, then reinserted.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I think that's it, thanks.

Hi, Thanks you for your question. so the key is in the car with you but pushing the start button does not start the car?

Your key fob battery may have died therefore not sending out the security frequency. What you need to try is holding the key up to the start button while attempting to start the car. This will activate the back up key sense. Let me know if this works.

Thanks,

Marc
