Wireless X10 light switch

Our son's room does not have an overhead light, so I install this wireless X10 light switch. It has been working great, except it gets reprogrammed periodically. This switch gets programed by pressing an hold the buttons for a few seconds. Since our son is tall enough now to press the buttons, he reprograms it regularly.




I need to find a different wireless remote, one that is not re-programmed by just pressing the buttons.
