This morning when I attempted to start my 2006 Hummer H3, nothing happened. I thought I may have a dead battery but the lights and radio work fine. I then noticed the Passlock security lock light was on (fixed, not blinking). I tried using the procedure stated in this site of turning the key to "on" for 10 minutes, then removing the key and repeating the procedure 2 more times. I then attempted to start the vehicle and again nothing happened. Can I disable the "Passlock" security system or is there something else I can do?

Why do I lose radio signal on my 2006 h3 hummer when I turn on my ignition? My radio works fine until I turn on my ignition.

If it works at the accessory position and not on the run position. I would go after the run wire to the radio. If other things don't work in the run position, look to the ignition switch.

2007 h3 radio not working and display time and "phone". if battery is disconnected it comes back on then goes right back after turned off and started back up.

1st mistake: you didn't get an H1 lol
2: Most modern cars have an anti-theft device installed in the radio. That means if the battery becomes disconnected for ANY reason your radio won't work without a special code being entered. Your local Hummer dealership should be able to provide you with a code. The code is NOT the same for every vehicle.

Went to start my 06 H3 and everything is dead. No electrical whatsoever. No I didn't leave any lights on. :) Now I can't even get the key to turn back all the way so I can't get the key out....

First check the battery connections. Make sure they are all clean and tight. Ground cable and connection to starter as well. Try getting a boost or put a charger on it. When you get it going, you'll have to check everything closely to make sure nothing is on. It is possible that the battery is just done, or the starter could be fried and just drained the battery. Let me know how you make out.

Hello:Try this procedure: turn key on, turn to start, let key come back to on wait ten minutes, turn key off wait 10 seconds turn key back on wait 10 minutes. turn key off wait 10 seconds turn key back on wait 10 minutes turn key off wait 10 seconds NOW try and start. In addition you might try tapping on switch assembly while trying to start. There is not any way to disable passlock. You might try having the engine control system codes read

i just bought a 2006 hummer and just started having the same problem - had to get it jumped three times in the last 5 days. I did not drive the two days it did not need to be jumped. Three hours ago I drove up to a friend's house. The car is dead again. I feel like I'm driving a first generation electric car.

Question:
what is the "wait" position? Thanks for the help,
Marti

Hello: Please read the procedure again, you DO not remove the key just turn it off and on the first attempt you go to the start position and then to on (run) There is an ignition relay and a start relay they are in the fuse box under the hood and on the inside of the top cover there positions identified.

Hi Bluebirdmate!
THANKS! This worked.... the hardest part was waiting the 10 minutes 3 times! SO, ? can we fix this problem ? The car belongs to my youngest daughter and I don't like getting the "MY CAR WON'T START!" call at 7:30 a.m. when I am at work and she is going to be late for school. What causes this problem? Please let me know if it needs to go to Chevy to be fixed. THANKS AGAIN!
