Are you sure it's a driver problem? What does it do/not do?

If you have a pair of long-nosed/needle-nosed pliers they should work fine, but you might need to file the tips down a little bit to fit into the holes on the driver board. That's all I've ever used and they also work good for removing/installing tailcap switches.

If it has a side switch, that may need to be removed also since it's connected to the driver with wires. I've never removed a side switch, but if it's a well known brand, just Google the name, model/model #, followed by the word review. There may be reviews on the flashlight forums or videos on youtube that show how to remove it.
