Look under all fuse box covers, ash trays and covers under the hood for a code. Pretty good chance it will be there if a tech has ever needed the code in the past.

Where is the reset button located in a 2003 Honda Odyssey for the anti theft?

If the remote was programmed before loss of power, push and hold the unlock button until the alarm stops. If not try locking and unlocking the drivers side door with the the key. This has reset the alarm on my 2001 Odyssey.

You will also need the unlock code to reactivate your stereo after long term power loss. It is on a card with the manual given to the owner of new vehicles. A smart dealer will put it on a sticker in the glove box. Otherwise you have to remove the radio and give a Honda dealer the radio serial number to get the unlock code. Don't try it randomly; 10 incorrect tries locks the stereo.

My 2008 Chevy Cobalt stock stereo has stopped functioning. It doesn't light up, turn on, nothing.

Have you had the battery disconnected recently? The stereo on GM cars have a security feature that locks them down if the power supply is interrupted. You would have to contact your dealership to get the code to reactivate the stereo. If there has been no disruption in the power supply, then check for blown fuses.

On my 98 intrepid 2.7 I have changed the battery twice and the alternator twice due to slow loss of power until it has a total loss of power. it takes about a week for this to happen. what is draining the...

Are you familiar on how to perform a current draw, by using a 12 volt test light? This will help isolate what circuit in your electrical is causing the draw, provided battery good, and alternator has been confirmed good. Simple to do, only takes your time, and a 12 volt test light, or any 12 volt bulb and socket you may have in the garage. Get back to me, for instructions if your not familiar with procedure.
One thing i will ask is, about the stereo, is it factory, or has someone changed it to aftermarket? That is a good place to start looking if it's not a factory stereo system. 12 volt plug in spots in interior are another, such as sockets for cell phone adapters to plug in etc.

I tried to install an aftermarket stereo in my 2005 jeep grand cherokee but it didnt work because i had the wrong wiring harness. but when i tried to put the factory stereo back in it wouldnt work either....

Check that the yellow and the red wires have power while accessories is on, using a test light or multimeter. If they both have power, check earth connection.
