possible blown stock amp.., It might be locked tho not sure Options

[bseaman_5]

So last summer I left my all my windows open and left w a buddy to go get a new phone, while we were gone it started raining and some people at his house tried to get my windows up but of course couldn't cuz I had the keys in the meantime they set off the alarm and then pulled the battery terminals to shut it up, well I think when they did that they locked up my amplifier so it would power anything up w the stereo.. I thought it was blown so i replaced it, today i was attempting to put in an old school cd player, but the wire harness I had for it had to be spliced and what not to get all the wires wired up.. Well i'm not sure if 2 wires hit together after I plugged it in or what but i heard some sort of electrical shock noise and now once again no power to the stereo.. any ideas??? I haven't checked the fuses yet, I just thought of that, and I'm work so I can't at the moment. I'll do that when I get home. but other than that any ideas? Would I have to go to a toyota dealership to have them see if they can unlock it if that were the case?
