It will not; safes in Fortnite are different from their chest counter-parts in that they give you no indication if you are standing right above one. If you are within close vicinity of a chest or even a legendary chest, you will hear a pleasant chiming noise stemming from the exact location of the said chest. If you are in the house or building, you will know if a chest is present. But that is not the case with safes. Safes make no noise, glow, or provide you with any signal that they are near. This makes it essential to have background knowledge on where safes should spawn. That way, you are not wasting your time aimlessly looking. The only time a safe does make a sound is when you finally unlock it. The sound is pretty loud, so if there are other players around you or in the same building, it is a dead giveaway as to where you are. So, only choose to unlock a safe if you are sure no enemies are around, or if you are playing on a team and have one of your teammates cover you.
