Guide Pins on 2001 stratus

Im trying to replace the brake pads and i have to take off the guide pins on the calipers. Im looking at them and I have no clue what tool I need to use. Anyone know what tool i need? Thanks

what shape does it look like? if it looks like a hex then you need an allen wrench if it looks like a star then you need a torx bit either one can be bought to fit on a ratchet hope it helps
