I am trying to install an after market tachometer in my 2003 Hummer H2 - the instructions indicate tying one wire into the ignition switch? Thanks, Larry D'Angelo


Any power source that is switched will work, so use a test light to find a fuse that is only powered when the key is turned to run.

Key is locked in ignition


Make sure the vehical is in park. If it is not, the key will not release. If you did not turn the key down far enough, or turned it too far, the key is in auxillery and needs to be switched to the off position.

My key In my 03 H2 is stuck it won't turn back all


Go buy some WD40 and spray it inside the ignition and while your doing that try and move the steering wheel side to side and try pulling out the key. You might want a extra person to help you let then turn the wheel while your pulling on the key but first spray WD40 in there it wont hurt it plus it lubricates the key and ignition trust me this works I have done this tons of times.
PS you can buy WD40 at any auto parts store or even at a Wal-Mart.

Hummer H2 engine won't turn over, key won't


Dead Battery? Bad starter motor?

Try pushing on the brake and making sure its all the way in park.

Turn the steering wheel back an forth a little to remove the key.

None of those work, Call triple A, find a shop.

Transferbox problems


It's actually stuck on the 4xL, if you keep driving it it might coz a big damage to ur 4wd gear box.
you should change the transferbox (it cost here in Dubai around 1350 US$ with labor charges).
it happened to me 2 months back.
