You could try hooking up a battery charger to the battery leads, then carefully remove the battery without interrupting the voltage supplied by the charger....just a theory as I have never tried this.

I changed the battery in my 2003 Montana and now my dash guages are dead. There was no short involved--only a simple battery re-placement. The radio also went into "lock".


The radio will go to lock when the battery power is disabled. They have a theftlock system installed where you have set a lock code in the radio, every time the power is removed the lock code has to be reinstalled to work ( this simulates the scenario where someone may steal your radio, therefore it is useless to them without the code). If you forgot your code, you will have to contact the dealer and get the initial radio code to reset it. Procedure is usually hitting 2-3 preset together (displays 3 digit code) then the AM button (another 3 digits) they then call Delcotronics and get factory override code. Quite common problem when code is set but most people forget their code. The dash lights however are not related to the battery replacement, I would recheck that the interior light override switch in the roof console is not set to off.

There is a security code for it, you may have to get it from the dealer or look it up online if its a factory stereo.

CHANGED CD PLAYER NOW SAYS LOCKED


look in owners manual/glove box for the manual for the radio or in the owners manual it should have a card or a piece of paper with the code on it. if not call your local dealer with the vin number and they should be able to tell you the code
