My Hummer H3’s year of issue is 2007 and odometer shows 81952 miles. Just bought it this year, in July. Every time I want to start my engine i’ve got passlock light and engine doesn't start. Had this problem couple times before and it was solved by locking and unlocking car for several times and leaving key in on position for 10 minutes for 3 times. Its third day i’m trying all the methods i know and tried before, but none of them worked, so i don’t know how to fix it.

 

Here's a video on how to replace the passlock=Easy to do.

In your case type "passlock" then go to the "Search in Forum(s)" section and find "Hummer H3", click it! Unclick "Also search in child forums" then click "Search Now".

You have now done a search for your passlock on an H3
