Remote Bombs

Hello again, I am in need of help, I have remote bombs I can shoot and stick to wall/players/themselves but, how would i make it so when ever i press use, all set bombs explode at once? I’ve tried KeyPressed, hook.Add, and a few other methods, but they don’t work, i’m reallly stuck on this one. Would it be possible to call it from the SWEP?

What do you meen KeyPressed won’t work?

Also, of course it would be possible to call it fromthe swep. EG. using the reload function as the detonation key [R]
