Can You Bring Bicycle Locks on Planes?

Theoretically, all types of locks are allowed on planes in the United States. TSA doesn’t list bicycle locks as banned items, and therefore, they are welcomed in cabin and cargo luggage.

However, security agents might deem heavier bicycle locks like chains and d-locks as dangerous potential weapons. While combination, cable, and folding locks have a better chance of going through airport security without any problems, they could also be seen as dangerous to other passengers. So, overall, it’s best to pack them in checked baggage whenever possible.
