2002 bravada locked up, system shut down

I went to start my 02 Bravada, everything lit up for a sec or 2 then completely died. the ignition will not turn the whole way back to let the key out. when i try to start it i get absolutely nothin, will not even turn over. the door locks will not work at all even with the remote entry. it does nothing and i mean nothing at all. there is a new battery in it as of about 3 months ago so it cant be that i would think..... what could have caused this and how can it be fixed? has about 90,000 miles.

Don't trust the new battrery, have it tested, i went through 4 aftermarket batteries in 6 months, gave up and purchased the factory batt, never had any further issues to this day, Kragen's are the worst.

Reset air temperature sensor on 2002 bravada

Shut off the engine of your Bravada, remove the keys from the ignition, and open the hood.
Locate the plug that powers the outdoor sensor. You will find it in between the front bumper and frame of the car, just to the right of the rightmost support bracket. The sensor plug is green.
Unplug the outdoor temperature sensor by separating the plug from its socket.
Plug the sensor back in, close the hood, and start the car. If the sensor's performance has not changed, it will need to be replaced.

My 2000 bravada wont start.

you pulled the ignition switch and installed a different switch

Is there a security system that doesnt allow you to start the oldsmobile brevada if it doesnt recognise the driver.

Yes, it works off of the key tho. Your key has either a chip in the shaft or a transponder in the plastic head that sends signal to the ignition/lock cylinder. The ignition then sends a signal to the TDM (theft deterrent module) also known as the "computer". The TDM then allows your starter to start. If there is a break anywhere in this system, the vehicle goes into security mode and shuts down the starter or injectors. The hard part is finding which area is causing the problem. Mechanics can change every part before "fixing" the problem. Ive had the best luck with just bypassing the entire system. Here is a link that explains the problem and a PERMINANT solution that you can do yourself.

97 Bravada keys locked in ignition, will not start, brakes locked

You need at least 10.5 volts in the electrical system for the ignition keys to release from the switch. Be careful that you don't damage the ignition switch, or your going to have to replace it if the passlock system is damaged. Good luck and boost the battery to get the keys out of the switch.

Key stuck in igntion.

Put the battery on charge or jump it. Basically it's locked in because of the lack of juice.

I would check the relay that operates the system. It is under the hood in the Maxi fuse box I think.
