I recently purchased a 2007 h3 with 99 thousand miles. I got in it the other day and it cranked and wouldn't start. The radio says locked and the security light on the dash flaws and goes off. I waited the 10 minutes and still had a no start even after about 8 hours. What can cause this?

 

Bad ignition switch?? Passlock issue??

 

Bad battery terminals, check to see if you can move them around.
Dying battery will also do this.
If not either of those then passlock or ignition.

 

ITs been at the shop for two days. They have no clue what it can be. They just know that it is for the security. I ordered a ecm from pcm of nc with the passlock deactivated just to see if that will fix it.

 

The guy at the shop told me everything looked good. But there was no injector pulse he couldn't figure out why.
