Replacing batteries on light-up pins?

[Rajah]

Does anyone know if you can replace the batteries on the light-up pins (not the new interactive ones but the ones with the on-off button on the back) without ruining the pin?

Yes you can. THe battery is a standard watch battery you can get at most dept. stores.
Take a tooth pick and take battery out and take it with you .
