Antler Case Reset Combination Lock Instructions

British-owned Antler travel cases use American Transport and Security Administration (TSA) approved "Travel Sentry" locks on their suitcases, backpacks, cabin cases and other travel luggage. You might want to reset your Antler Travel Sentry lock if the someone finds out the combination or if you suspect the code is too simple to guess. To ensure the maximum level of security, the lock requires the existing three or four-digit code before programming a new one.
