When the car door opens, the headlight left on alarm "bings" continuously until you close the door. I thought it was the key in ignition alarm, but when you put the key in the ignition, and have the door open, the alarm sound slows down - remove the key and the "binging" speeds back up again. Lights on or off makes no difference.
Any ideas? IF I can't fix it - where is the alarm fuse?
The Body Control Module (BCM) controls the audible warnings. Refer to Body Control System Description in Body Control System for more information regarding the BCM.
The body control module (BCM) controls these reminders:
• Key in ignition reminder: An audible warning intended to remind the driver that the key has been left in the ignition cylinder. The BCM sounds the chime for this reminder at a rate of 150 chimes per minute.
• Fasten seat belt reminder: An audible warning intended to remind the driver at the beginning of the driving cycle that the driver's seat belt is unfastened. The BCM sounds the chime for this reminder at a rate of 50 chimes per minute.
• Fasten belts indicator control: A visual warning intended to remind the driver that the driver's seat belt is unfastened.
• Parking brake reminder: An audible warning intended to remind the driver that the parking brake has been left applied with the transaxle shifted out of PARK. The BCM sounds the chime for his reminder at a rate of 200 chimes per minute.
• Turn signal reminder:
An audible warning intended to remind the driver that the turn signal has been left on while the vehicle has traveled over 1.2 km (¾ mile). The BCM sounds the chime for this reminder at a variable rate (in unison with the turn lamps on) of 90 chimes per minute.
• Headlamps ON reminder: An audible waring intended to remind the driver that the headlamps have been left on. The BCM sounds the chime for this reminder at a rate of 200 chimes per minute.
• Last door closed locking confirmation: An audible warning intended to provide the driver feedback that the last door closed locking feature is active. The BCM sounds the chime for this remainder at a rate of 200 chimes per minute.
• Feature customization and diagnostics feedback: An audible feedback used when changing feature customization modes. Also used by service technicians during the BCM diagnostics. The BCM sounds the chime during the feature customization, and also during diagnostics. Refer to Body Control Module (BCM) for additional information.

Your best bet ,take it to a qualified repair shop
SOURCE: Left side rear door will not unlatch.
stupid question but did you try inside latch?If so you should be able to remove seat from other side and remove door panel and replace parts (probley clip) as needed or at least open door if latch is defective
SOURCE: Radio, Key auto door lock/opener, interior lights not working.
Most likely is a fuse. There is a fuse box at the end of the right side of the dash. Open front passenger door and there is a cover that says fuses on the end of dash. There is also a fuse box located under the hood at the right front of engine compartment. It should have a cover with a round knob in the middle of it .Unscrew the knob to remove cover.
SOURCE: ignition switch on a 2002 chevy trailblazer
under the steering column, there are three or four little holes in the plastic covering. If you look inside, one of them (the one on the right side toward the dash) there is a brass pin inside. This is the pin to release the key. As far as the key not turning, I have had the same problem. The first time I replaced the ignition switch and that solved the problem. However, this makes no sense because the ignition switch has nothing to do with the tumbler being locked. GMC thinks that my anti theft system, which is inside the ignition cylinder is the problem. By removing the ignition switch, it reset the pass lock anti-theft system and temporarily fixed the problem. So, try removing the ignition switch and then plugging it back in. If that doesn't work, your in the same boat as I am, and we may both need new ignition cylinders.
SOURCE: Remote Door Lock/Unlock will not work.
At first look, I would have guessed that your battery in the door opener was dead, but that is not the case. I suggest driving to a nearby Chevy dealer and ask one of the salesman if he/she can help. They have always been helpful to me. If not try another one as they are in business to sell not only cars, but service also. They will be your best bet to fixing it. :D
