remote entry?

assuming you have power everything it would be pretty easy to install an alarm system to a non-keyless entry equipped car right? it just seems like it wouldn't be that difficult, you'd just have to by the brain/computer for it.

I think it's totally impossible but has anyone ever thought about trying to make an automatic top opener for our verts? I'm talking from the locked position to completely open. -some alarms have the option of a remote top opener, that's why i'm wondering
