Fans of HGTV may remember Matt and Shari and their Room by Room TV program. I was looking around on their website recently and found they were featuring a neat product for keeping your spare house key safe outdoors. The RocLok isn’t like those fake plastic rocks with a drawer on the bottom to hold your spare house key. These rocks are molded from castings from real rocks, and hand-stained for a natural look that will blend in with your landscaping. They’re cast in fiberglass-reinforced cement that is actually stronger than real rocks because the cast stone doesn’t have the fracture lines that real rocks have. There’s a storage compartment with a combination lock with 1000 possible combinations hidden in the bottom of the rock. It’s recessed into the rock to prevent the lock from getting wet and rusting. The different styles of rocks range from 4 pounds to 12 pounds and cost from about $65 to $70.
