Can anyone name this movie?

[Atrandomx]

Hello, this is my first time creating a thread, and I hope one such as this does not already exist, though I cannot find one.

So I have been searching off and on for a long time for this 80's/early 90's Horror movie that I watched when I was a kid, and no luck.

What I remember from this movie is fragmented but I'll give as many details as I can: I remember a scene where a girl falls off a roof and these "monsters" catch her and kidnap her away and her boyfriend is unable to stop them. Another scene I recall is of her boyfriend on skateboard going to rescue her (probably near the end). And then I recall him finding the monsters lair/hideout where the girl is being held and they make him select a room out of maybe 4 or 5 rooms that she could be in. He ends up chooses wrong. Oh, he also has some sort of device that is supposed to "stop" or "kill" the mosnters, but doesn't work when he needs it.

Thanks in advance for any and all help, I really appreciate it and hope someone knows their Horror films!
