Found an answer on the beeping right here in the forum. For anyone wanting to turn off the beep, look here:

Cheers, JY
Does anyone know how to silence the locking and unlocking? I bought a used i3 and it was silent. Had the dealer work on it and now it beeps upon lock and unlock. Annoying to me.
Thanks in advance, JY
