Needing some help with an ongoing alarm issue with my 2012 tundra. I have an alarm that is randomly going off for apparent no reason, mostly in the middle of the night although it has happened a couple of times in the evening. I have a good friend who is a Honda Tech, and occasionally works on Toyotas hook it up to his scan tool and it pulled a few codes. First code is P1604, which I believe is due to the fact that I have been unplugging the battery every night because it's been waking up my neighbors.....not good, second is B124 with a likely cause of it being dusk and the sensor not registering sunlight. The last one is the one I think may be my issue its B2602 Key Unlock Warning Switch. I've done some searching on this forum and on google and can't really seem to come up with much. Does anyone have any knowledge of this code or 'Key Unlock Warning Switch'. Thanks!
