Ok...DH finally installed our cabinet locks...we went with the tot locks because they get such great reviews. Most of them work great, but for some strange reason, two of them don't work very well. Sometimes they work, other times they don't. The problem isn't the little cushy pads on the cabinet doors - Even with the door open the magnet key doesn't work. Anyone else have this problem?? I'm thinking that maybe these two are defective?? Could it just be an installation problem??
