These locks work great. You don't need to screw anything in as it comes with strong adhesive tape. The key is a magnet. You can use any stronger magnet and save yourself $ on buying the key. We used a chip clip magnet. It has to be strong enough to go through your cabinet doors.The best thing is you can unlock the lock when your child is not in the kitchen. Then when they enter the kitchen, you can enable it. There's a switch you click to turn the lock "off".To the reviewer that says you can't find the key at any stores - Use a stronger magnet and save your $
Tried numerous different child locks. These were the easiest to install. Blow Tot Loks away. No need to drill holes. The only drawback is that they don't work with all types of drawers but cabinets are a snap.
