BCM Replacement?

[blazer230]

I have a 2008 Quest. Manufacture date 5/08. Having a lot of electrical issues such as back gate not working (just solid beep if handle depressed on outside), windows not working correctly, constant beeping at times (seems worse if raining). Talked to a few local mechanics as well as Nissan dealership and all have said it sounds like the BCM is going bad. My question is if I buy a BCM off of a wrecked Quest (which I did today) same year model and after Feb. manufacture date. Can I basically just plug and Play or does it need to be flashed? I am getting conflicting reports as to this. Just need to make sure if I go through the trouble of removing and replacing that it will still start and run as it is my only vehicle.

Thanks
