Luggage locks are small security devices designed to protect your bags and belongings while traveling. They can be used on suitcases, backpacks, and other types of luggage to deter theft. Many luggage locks come with a combination code or a key, allowing travelers to secure their items easily. Some luggage locks are approved by the Transportation Security Administration (TSA), which means that TSA agents can open them with a master key if they need to inspect your luggage. This feature helps prevent damage to your lock while ensuring that your belongings remain secure during your journey.
