Dell latitude 3420 keyboard compatibility?

Hello guys, recently purchased a refurbished Dell latitude 3420, thing's a workhorse so far and I'm pretty impressed with it. The only issue I have with mine is that it doesn't have a backlit keyboard, I noticed that other versions of the same laptop have a backlit keyboard. My question is if I buy a backlit keyboard for the latitude 3420 will it be compatible with my laptop?
