Apparently, if you press two buttons at once on this remote, you activate the child lock. As a result the remote does not work. It turns out it is surprisingly easy to press two buttons at once - given that the buttons are so close together and that the remote is not litAt night. I read one review where a woman said that she repeatedly accidentally pressed a button that caused your husbands vibration feature to activate, thereby waking him up! My worst experience was when the bed locked in the upright position at 2 AM.
