Yesterday I had some battery issues and had to get my battery replaced today but it looks like due to having my electronics shut off it reset my stereo and now the stereo is asking for a "code"

I called the dealer and they said my serial number would be on a sticker in my glove box area but i didn't see one. So he said the only other way would be to remove the stereo to get the serial number off. Anyone know an easier way to get my stereo serial number if im not the first owner? Or i was hoping someone could tell me how to take my stock head unit out w/o completing messing up my trim around the unit? (i've attached pics just in case)

BTW i saw that post on here before but it never clicked in my head and you just saved me alot of hassle because i was about to walk out to my car with a flathead and try and rip out my stereo just to get the number off the back...my acura thanks you
