Question about 2002 Chevrolet TrailBlazer
I have a 2004 Trailblazer that I hardly drive, I keep it in a garage so it's out of the weather, my battery is currently dead and I went to jump start it so I could drive it to charge battery, needless to say the key fob won't unlock the doors as the battery is stone dead, therefore, I tried to unlock the door with the key, it won't unlock. I have no way really to get in to even jump start it, I called local dealer and they told me to try my other key as maybe it's a problem with the key. They're saying that the key itself should unlock the door but it's not, it'll turn in the key hole but the door will not open. I'm going to try my other key but if this doesn't work what are my other options, I don't want to break the window to get in. Some dealers are telling me that a slim jim may and may not open door, any suggestions would be greatly appreciated!!!!!!!!! HELP ME!

SOURCE: key fob will not undo
If you don't have one that works for the vehicle now, you'll have to take it to your local dealer to have it programmed to the vehicle. Some will charge for this, some will do it at no charge.
If you do have a remote that is programmed and working for the vehicle, then the following steps will allow you to program another remote:
1. Enter vehicle and close all doors.
2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.
3. Put key in ignition, turn to run position but don't start it.
4. Press and hold the unlock button on the working key fob and hold for 4 seconds, then also press the panic button.
5. Release both buttons and you should hear a single chime to indicate it is in program mode. You have 30 seconds after the chime to program any additional remotes you want to program.
6. Press and release both the unlock and lock buttons simultaneously on the remote you are programming. You should hear another single chime.
7. Within 4 seconds after hearing the chime, press either lock or unlock button on remote that you are programming.

Your key can only be programed at the dealer. They have to use a scan tool and a unique id code that they get from the factory. It is done this way to help insure that the vehicle is less likely to be stolden.
