This design ensures convenience, safety and user-friendliness. It requires just 0.5 seconds to activate or deactivate the lock. The lock is made from strengthened stainless steel and is designed to prevent break-in or explosion. The innovative keys are only authorized for the owner to use. If deactivated using the app, the keys no longer work. If any object is inserted into the key hole, this will trigger the alarm and send a message to the owner's phone. The push-pull door handle design ensures that children or adults carrying heavy objects can open the door easily.
