Can I bring a smart door lock in flight, in hand carry or check-in bag?

enter image description here

Inside it has a battery and weighs about 3 kg.

    Where are you travelling from (and to)? How is the lock powered? What kind of battery is inside?

    This is going to depend on the size of the battery inside the lock, as well as the restrictions that the specific airline you are flying with places on carrying batteries in luggage. Without this information we cant really give you an answer.

  • The TSA website is reliable reference point on luggage restrictions

  • If the battery is removable then yes you can bring it but in other case you can simply put it in the check-in.

If you can remove the battery (most likely you can) then you can check it in or hand carry. If you cannot remove the battery, it’s a big depends.

If the lock is too big it may deems as a weapon and you cannot hand carry so maybe you have to check it in.

  • With enough tools you can remove the battery from pretty much any device out there :-)

  • Agree :) most of times I can remove battery but I cannot put device back into one piece. You can ask my wife :)
