Those particular keys have a built in transponder in them. You need to go to the dealer and buy a key.

2008 trailblazer shifted from neutral to drive had it jacked up before now wont go into park and nothing works

Since you had it in neutral, the battery could have drained. Many things are still on when you can't turn the key completely off. And you can't when it is in neutral.

How to unlock my 08 chevy trailblazer, the battery is good but a light comes on the dash with a car symbol and a locked lock on the car and my car wont start (also my radio has been locked too)

check fuses relays and battery --lights going on is not an indication of battery being good --test battery with a meter or try boosting but your problem more than likely is key or ignition switch check --your key if worn or have chip key and chip/battery fail truck will not start if you have the other key try that one or try the relearn for the passlock system the link has information on how to do it

How to reset check engine light on 2008 Chevrolet trailblazer

No, the check engine light will not reset unless cleared with a scan tool or after a lot of key cycles with the problem resolved. You need to get it scanned to see what the code in the system and have it repaired. Most autozones will scan your codes for free - but they just give you the code and their guess of whats wrong with it.

Cheapest alternative to purchase a "new" remote key fob is on eBay. Search for "remote key fob, 2004 Trailblazer". Check and/or inquire about programing instructions.

Intermitent problem. engine will not turn over when key is turned.

Sounds like it may be the ignition switch, which is a common failure with these. Not the switch the key goes in, but the actual ignition switch, it's under the plastic cover just below the key switch.

Battery dies when its cold, this morning tried to jump it and was dead and now the key won't come out of the ignition

Weak batteries just don't make it thru the winter. I replace more of these than anything at the onslaught of winter. As far as the key, put some juice to the battery and it will come out.

My key does not unlock my door anymore. I can only unlock my vehicle with the remote. I'm afraid I won't be able to get into my vehicle if I misplace my remote! Any suggestions? The headlight went out on...

as for the door lock, try spraying a little white lithium grease in the key hole and insert your key and rapidly move in and out to get the tumblers loose again and get it working. now, as for the head light, just go to your local parts store and they will gladly help you get the right bulb for you and can even help you replace it if needed.
