I believe if you can open it up (btforums.com for step by step or youtube) you can just remove the cmos battery on the mobo and let the bios reset that way? I'm not sure if the rescue password is locked on the nvram in which case you're likely out of luck but I doubt it.
Hopefully this puts you on the right track. $165 for this is too high but considering they don't have time for this, they cannot charge you $20 for this.
