Q: How to reset RAM when keyboard isn't working

My MacBook Pro could not be turned on, the screen is black and it beeps 3 times, pauses and repeats. I checked online that I need to reset the RAM. Bit my keyboard isn't working and I've been using external keyboards. I tried to reset using external keyboard but it doesn't work. Is there anyway I could reset the RAM without using the keyboard? I tried opening the back, it didn't help.

MacBook Pro (13-inch Late 2011)

" I tried to reset using external keyboard but it doesn't work."
That would be resetting NVRAM or PRAM. When the three beeps indicates is that your RAM is damaged or corrupted:
Mac computers: About startup tones - Apple Support
So not reset but reseated. The bottom has to come off and the RAM taken out and inspected as well as the sockets and reseated.
More Beeps? One at a time and change sockets.
More Beeps? Put in known good.
More Beeps? Bad sockets or bad logic board.
