Why You Need It: No more children or pets locking you in a room; prevent children from entering specific rooms like bathrooms or storage closets without adult supervision; stop children from playing with the door and pinching their fingers. Upgraded Double Lock System: Childproof door locks feature a double lock system that prevents children or pets from opening doors, keeping them in a safe place. Child safety locks are the perfect way to ensure a completely safe childhood. Wide Application and Anti-Locking: The door handle lock is compatible with most standard door handles. With 2 side buttons to manage the "Disable" mode, the safety lock prevents you from being blocked by your children. Easy Installation and Removal: No tools or drilling required. The safety door lock can be installed with a simple peel-and-stick 3M adhesive. To remove, heat the baby lock with a hairdryer for about a minute, then gently remove the adhesive. Safer and Durable: The handle lock is made from non-toxic ABS material. The durable handle lock is strong enough that young children cannot remove it, providing them with a safe space.
