  • Patent number: 4712396
    Abstract: This invention provides a means for permitting the deadbolt lock, as used on many residential outside doors, to be quickly and conveniently locked, either from the inside or outside, without requiring the use of a key. This device then requires that the deadbolt lock be opened from the outside by a key in the conventional manner, or from the inside by a conventional finger lever. But to prevent accidental lock out of the resident, this invention further embodies an audible reminder to the user to make sure that the key is in his possession and available for re-entry purposes.
