Hi, I'm looking for improved ideas for a time delay for releasing a key. I've previously used Emlalock, but one of us always ends up remembering the combination from the picture when desperate. We've also tried freezing the key in a bottle of water, but find that easy to circumvent with hot water, of course. I'm trying to find cheap but efficient ways to force a delay on a chastity key, that CAN NOT be rushed, or at least much compared to melting ice in a water bottle or thermos. Time-release safes are out of the question due to beings hundreds of dollars or more. Otherwise, whenever even with agreement, one of us ends up wanting the unlock the other bad enough for our own use, we speed up the key release. Thanks!
