Disabling door locks
 

I have a 2004 Chevy Silverado that had a stock stereo in it. With the stock stereo, I had disabled the door locks.

Since then, I have replaced the stereo with an aftermarket and have conducted maintenance on the truck. In doing this, I have disconnected the battery which reset the computer and now my locks are reengaged.

Without the stock radio...how can I disable the auto door lock feature with my aftermarket stereo?

Any assistance or back door procedures would be greatly appreciated.

Thanks,

Jim
