Hey, will a car jumper work?

I dont care if i break it... But im makin the small pill one. and i need a small igniter?

Its a fire one, like for candles. Ive seen friends make mini stun guns

Where do I connect the pins if its just the lighter?

I want to open it....to ignite. Right now its just a dumb lighter. I want it opened so i can just use the electric part.

I'd like to use a bbq lighter, but i cant open it. Is it safe to use a screwdriver or knife.
