My child lost the house key, and we filed a lost property report with the police, but it hasn't been found. For security reasons, we replaced the lock, so this is the item for sale. There are three keys as shown in the photo. This is a type that is installed in two places, top and bottom. The keys are expensive and cannot be duplicated. An installation manual is included. Installation takes about 15 to 20 minutes and is easy to do.
