Seeking help finding 3rd key to Bio Lab level for Die Hard Trilogy 2-Arcade level. Have found the key in the monkeys cage and have shot the guard in the garage and recovered the 2nd key but have not recovered the 3rd key as yet. Can someone assist me, have looked almost everywhere?

I'm sorry! I'm not sure how I missed this question but I did...
anyway...if u still need the help...
I'm assuming u'r talking about the 3 security cards u have to get...u need to defeat "boss nutter" (??) ...the last card is on his body after the fight is over. *If this isn't what u need or if u need more help feel free to post again
I'll try to pay more attention next time so you don't have to wait so long for a response
g'luck!
