Review: Solid Lock with Easy Combo Setup - I bought this Master Lock for multiple rifle cases, and it does exactly what I need. Setting my own combination was quick and straightforward thanks to the clear instructions. Once set, the dials turn smoothly and feel solid. The build quality is solid for general use. It’s not meant for ultra-high security situations, but for luggage and rifle cases, it works perfectly (i.e., checks the compliance box for rifle cases in MA). I also like not having to carry a key around. Overall, reliable and convenient. Review: Reliable and Easy to Use – Perfect for Travel! - These Master Lock TSA-approved locks are exactly what I needed for travel peace of mind. Setting my own combination was quick and simple, and the instructions were very clear. The flexible cable shackle makes it easy to thread through zippers or awkward loops on luggage and backpacks. They feel sturdy and well-built, and I love that TSA agents can unlock them if needed without damaging the lock or my bag. I’ve used them on several trips now and they’ve held up great with no issues. Great value for a 2-pack, and the random color variety was a fun bonus. Highly recommend for anyone looking for secure, dependable travel locks! ## Features - TSA approved luggage lock enables screeners with the ability to inspect and relock luggage without damaging lock - Set your own three-digit combination luggage lock; TSA lock is best used as a luggage lock or backpack lock - Travel lock is constructed with a metal body for durability and a vinyl covered cable for resistance to abuse from baggage handling equipment - 1-3/16 inch (30 millimeter) wide lock body; 1/8 inch (3 millimeter) diameter shackle with 1-1/2 inch (38 millimeter) length, 5/8 inch (16 millimeter) width - TSA lock is best used as a luggage lock, backpack lock, tent lock, tool chest lock, or as a storage case lock ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003P0WLZY | | Additional Features | TSA Approved | | Best Sellers Rank | #14,481 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #9 in Luggage Locks | | Brand Name | Master Lock | | Color | Silver | | Control Method | App | | Controller Type | Jog dial | | Customer Reviews | 4.3 4.3 out of 5 stars (21,511) | | Finish Types | Powder Coated | | Global Trade Identification Number | 00071649152726 | | Included Components | 1 luggage lock | | Item Dimensions | 5.2 x 3.1 x 0.9 inches | | Item Type Name | Set Your Own Combination TSA Approved Luggage Lock | | Item Weight | 2.4 ounces | | Lock Type | Combination Lock | | Manufacturer | Master Lock | | Manufacturer Part Number | 4688DSLV | | Manufacturer Warranty Description | Limited Warranty | | Material Type | Alloy Steel, Metal, Vinyl | | Model Name | Set Your Own Combination TSA Approved Luggage Lock | | Model Number | 4688D | | Number of Pieces | 24 | | Recommended Uses For Product | travel | | Shape | Rectangular | | Smart Home Compatibility | Not Smart Home Compatible | | Style Name | 1 Pack | | UPC | 071649152726 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Master Lock - **Item dimensions L x W x H:** 5.2 x 3.1 x 0.9 inches - **Lock Type:** Combination Lock - **Material:** Alloy Steel, Metal, Vinyl - **Special Feature:** TSA Approved ## Images ![4688D Set Your Own Combination TSA Approved Luggage Lock, 1 Pack, Silver - Image 1](https://m.media-amazon.com/images/I/61rosUorLRL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: One pack at $6.99 contains one lock and the 5-pack at $79.99 means $15.99 each piece. Do I get it correctly?** A: Good question. I just bought one unit to try first, even though I know that my luggage and backpack will use more locks. Sounds to me like someone in sales there is asleep at the switch. **Q: Will this fit through the holes in a zipper (i want to lock to zippers together)??** A: The exact size the cable will pass through is 9/64 or 3.57mm. this has been checked with a drill gauge. It will NOT fit through a 1/8" hole **Q: Is the cable easier or more difficult than the rigid locks to attach to suitcases?** A: I find the cables to be much easier than the rigid locks because you don't have to jiggle the whole lock around to find that magic angle that will allow it to pass through the things you are trying to lock. All in all the cable adds a few more degrees of usefulness to the traditional rigid lock style. **Q: have gun case with 1 inck lock holes, will this lock close** A: keep in mind that these locks work great but can be a challenge to get open at times... so you may want to give more consideration if this is being used to lock a gun case that you might need immediate access too ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid Lock with Easy Combo Setup *by D***. on July 7, 2025* I bought this Master Lock for multiple rifle cases, and it does exactly what I need.

The bags come easily on and off with a special MIK key, but I really didn't want to be taking the bag on and off everywhere I stopped. I don't live in huge city where theft is a huge issue with bicycles, so I figured a simple luggage lock would suffice. This lock really fits the bill. It goes through the zippers for the bag to lock it, and fits perfectly in the bag's side pocket when I don't need it. So far I have not had anything stolen while I'm at work or in restaurants/bars on a ride. The only negative I would say about this lock is that numbers don't click into place very well, so sometimes you may not have the number selected that you think because it's just slightly off. ## Frequently Bought Together - Master Lock 4688D Set Your Own Combination TSA Approved Luggage Lock, 1 Pack, Silver - Apple AirTag --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/3664461-4688d-set-your-own-combination-tsa-approved-luggage-lock-1](https://www.desertcart.us/products/3664461-4688d-set-your-own-combination-tsa-approved-luggage-lock-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
