If you have a young child, you probably already have safety locks on your cabinets and drawers. Adding a safety lock to your range and oven setup will keep your child from opening the oven door and getting a nasty burn. It's a minor feature, but it could be a vital one, especially if you typically perform chores in other parts of the house while your oven is doing its thing. This feature doesn't add much to the price of an oven setup, so be on the lookout for it. You've already hit most of the kid safety highlights; don't let this important detail slip by you.
