Is this Master Lock 20mm padlocked approved for airline travel?

This lock features a compact 20mm profile ideal for luggage zippers. However, please note it is not a TSA-approved lock; if airport security needs to inspect your bag, they may cut the lock if you are not present.

How many combination possibilities does this 3-digit lock have?

The lock features a 3-digit dial mechanism that provides exactly 1,000 possible custom combination codes, making it highly secure against random guessing by opportunistic thieves.

Is it easy to change the combination code?

Yes, absolutely! The 646DAU is designed with an easy set-and-reset mechanism, allowing you to personalize your security code as many times as you like in just a few simple steps.

Will this 20mm lock fit through standard suitcase zipper holes?

Yes, this is specifically what the 20mm size is designed for. The shackle is thin and sleek enough to slide effortlessly through the small holes of standard luggage, backpack, and briefcase zippers.

Can I use this lock outside on a garden gate or shed?

No. This lock features a compact metal body optimized for indoor and travel use, such as gym lockers, backpacks, and suitcases. For harsh outdoor environments exposed to heavy rain, we highly recommend our brass-covered Master Lock Excel series.

What happens if I forget my custom combination code?

For security reasons, there is no master override key or reset button on this lock. If the combination is forgotten, the lock cannot be opened or reset, so we strongly advise writing your code down in a secure location.

Is the body of this lock made of cheap plastic?

Absolutely not. The Master Lock 646DAU features a tough, durable solid metal body engineered specifically to withstand the heavy bumps and rough handling of airport baggage carousels.

Can this lock be used for a standard commercial gym locker?

Yes! It is the absolute perfect size for day-use gym lockers, school lockers, and staff locker latches, allowing you to exercise completely key-free without worrying about losing a physical key.

Does it come factory-preset to a specific code?

Yes, like most combination padlocks, it traditionally arrives factory-preset to open on 0-0-0, allowing you to immediately unlock it and set your own custom code right out of the packaging.

Do you offer trade or bulk pricing for school districts or fitness centers?

Yes, Freshway Supplies provides highly competitive volume pricing and trade accounts for schools, universities, commercial gyms, and facility managers purchasing bulk keyless security locks. Contact us to get a quote.
