You will definitely want to get this key set to go along with the regular lock set. We usually buy one extra so that just in case we lose a key we have a spare. This system works great on your cabinets and there's no drilling required! The adhesive is very strong, my kids have tried to yank the doors open and are unsuccessful! The only hard part is finding a place to put the key so that it is out of reach of the kids but easy enough for you to get to it each time you need to open your cabinets or drawers. I would definitely recommend these to anyone who needs to baby proof their home. My favorite part is that you don't have to drill into your cabinets or drawers so it seems like when you don't need them anymore they'll be easy to remove and it will be like they were never there! Ease of Use Pretty easy to install since it's just adhesive for most areas. Safety Keeps the kids out of places they shouldn't be! Durability you will need to screw them in instead of using the adhesive if you plan to use them where they could get wet like under the kitchen sink.
