Buying Guide: Key Purchase Considerations

• Lock Type and Security Level: Decide between 3-digit versus 4-digit combinations. Four-digit locks offer more combinations and greater security, but require slightly longer setup time.

• Durability and Materials: Aluminum alloy, zinc alloy, and hardened steel components improve resistance to tampering, weather, and rough handling.
• Shackle Design and Clearance: A wider shackle can accommodate thicker zippers or multi-layer luggage, but may be bulkier; ensure compatibility with your bags.
• Open Alert Indicators: Some models provide a red or pop-up indicator to signal that TSA opened the luggage, aiding quick checks on arrival.
• Set-Up and Reprogramming: Choose locks with simple reset mechanisms to avoid accidental changes; consider whether you want a keyed or combination model.
• Number of Locks: If traveling with multiple pieces, evaluate whether a pack (2-pack or more) suits your needs and provides convenient multi-bag security.
• Value and Warranty: Look for models backed by guarantees or lifetime warranties, especially for frequent travelers who rely on long-term durability.
• Color and Visibility: Consider color options that help you quickly identify your luggage on the carousel and reduce mix-ups with others’ bags.
• Budget vs. Features: Balance cost with features like open-alert indicators and higher combination options to maximize security without overspending.
