My gmc sierra truck was running now this morning it won't start and stay running and my radio won't work and doors won't lock/ unlock and dash says unknown driver

I would unhook the battery for about 10 minutes, hook it back up then see what it does, if that doesn't work check battery, or go to owners manual to reset system.
