## Description

♦ Airport Theft is More Common Than You Think. Between 2010 and 2014 the TSA reported more than $2.4 million in missing items at American airports alone. 25% of these thefts happened in the baggage pick-up areas. ♦ TSA Locks Work as an Excellent Deterrent. With so many bags unlocked, other people present and limited time to work in, thieves will pass locked bags by in favor of easier unlocked targets.♦ An Alloy Body Designed for Tough Work. SureLock uses a 100% alloy body which is built with the stress of airport handling in mind. We back this up with a lifetime warranty which covers damage caused by baggage handlers and TSA inspectors. ♦ Know if You’ve Been Inspected Right Away. There’s nothing worse than getting to your hotel and discovering that the TSA has lost an important item when inspecting your luggage. SureLock’s inspection indicator will let you know if the luggage has been opened right away so you can deal with any problems while you’re still at the airport.

Review: A quality lock and very versatile in its uses! - After looking at pages and pages of TSA approved luggage locks, I decided this two-pack of SURELOCK was the best option. I missed the 20% off sale so I’m a bit disappointed about that but it doesn’t change why I chose these locks over so many other options! Specifically, I like the following features about these particular locks: 1) A lot of the other combination locks only have three digits. This one has FOUR and I expect the added digit will make it even more difficult for someone other than TSA to unlock it. 2) The instructions are well written and easy to understand & follow. 3) The lock is TSA approved so IF TSA goes into the luggage, a little red indicator button will pop up to alert me the bag has been opened. Per the instructions, this button will reset automatically next time the lock is opened with the combination. 4) The locks are very versatile so you’re not limited to using them exclusively for luggage. 5) There are a lot of color options available. I’m hopeful the bright green against blue luggage will make it easier to identify my luggage on the baggage turnstile. 6) I didn’t check the diameter of the shackle loop before purchasing this item but it fit perfectly through the zipper rings on my suitcase [TravelPro]. They lengthened the shackle loop so it glides through the zipper rings without a struggle. 7) I especially like the STEEL shackle loop for its extra strength and durability. There is really no comparison to a cable loop in my opinion. 8) Resetting the combination was really simple! 9) Even though I missed the sale, these are reasonably priced and lock has some weight to it. You can feel the quality. I’ll put this to the test closer to the holidays but for now, I am very happy with the quality of the lock, ease of use, color options and the price!
Review: Great lock - Great, sturdy and easy to operate. Nice bright color so easy to see when looking for your luggage on a baggage carousel.

## Features

- THE MOST DURABLE LOCK ON THE MARKET. SureLock uses an ultra tough alloy body to protect our locks from the harshest of baggage handling. Our hardened stainless steel internal lock mechanisms won't rust or freeze up even after years of use. Put our locks to the test. We back them with a complete money back guarantee.
- NO NEED TO REMEMBER A COMBINATION. Many travellers will use their TSA locks once or twice a year. Because of this, it can be easy to forget combinations. You can avoid this problem by using a keyed lock.
- ALL LOCKS IN A PACKAGE ARE KEYED ALIKE. If you order four locks there's no need to have four separate keys. The extra keys provided can be kept in a safe location or given to family members.
- GREAT VALUE FOR COST. Because the internal mechanisms on a keyed lock are simpler and a combination lock, we're able to offer these locks at a significantly lower price than other TSA compatible locks. You're getting tough lock with an alloy body and hardened steel shackle at an excellent price.
- A WIDE VARIETY OF USES. These locks can be used to secure gym bags, gun cases, lockers, briefcases and more all in addition to their primary use of protecting your luggage.

**Q: Can I buy a four pack of the blue or black locks?**
A: You will have to look at the product information.

**Q: It is unclear how many locks are being offered for the price of $19.85. What does this price buy me in terms of quantity?**
A: Thanks for your question. $19.85 is the price for four locks. Have a great day

**Q: My 2 luggage was opened by tsa with this lock. how to reset the red indicator because it will not reset using the guide and won't lock anymore?**
A: Thanks for letting us know about this problem.  It sounds like the TSA may have incorrectly re-locked the lock so let's get you a replacement.  Could you e-mail us your current shipping address as well as the Amazon order ID # for your purchase?  You can find our contact information on the box or by clicking on our seller name (SureLock) on the product's details page.  Have a great day -Taylor

**Q: I followed the instructions in the package to reset my code from 0000. The lock is now closed and won’t open using my new code or the factory setting**
A: Try going to either the factory setting 0000 or your new code and move each number individually up and down 1 to 2 numbers then back to where they were.  as you move them, try to open the lock.  For example, if the new code is 4444, try 4445 then 4446 then 4443 then 4442, go back to 4444 then try 4454...  It might work
