Will I get electrocuted if I touch the inside of the car lighter?

My brother borrowed my car and smashed my iphone connector into the lighter hole, breaking the iphone connector into pieces. He pretending he didn't do it and has left fixing it to me.

Now a part of the connector is stuck inside, if I stick pliers or tweezers into it while the car is off, will I be okay? Or do I have to disconnect the battery? I don't know anything about this kind of thing!

Pull the fuse or disconnect the battery, it's the same as an electrical outlet in the house.
