Protection isn’t just what we make—it’s who we are. That’s why we were honored to partner with the Boys & Girls Club of the San Fernando Valley, Los Angeles Fire Department, local businesses, and community leaders with Mayor Karen Bass to place 500 fire- and water-resistant safes into the homes of families in the East San Fernando Valley. When the unexpected happens, the things you can’t replace deserve protection. By helping families safeguard critical documents and valuables, we’re doing what we believe in most: showing up, standing guard, and helping communities feel more secure. Thank you to our partners for sharing in this mission. Preparedness saves lives. Visit ReadyLA.org to sign up for alerts and access life-saving preparedness resources.

Every year, gyms see a huge surge in new members. In fact, January accounts for roughly 12% of all annual gym memberships, as millions set New Year’s resolutions. While motivation spikes, locker theft doesn’t take a holiday. Surveys show that ~34% of gym members have experienced or know someone who experienced locker theft in the past two years. From wallets to phones—and sometimes even keys that could compromise homes or vehicles—these incidents are more common than many realize. High foot traffic + short attention spans = opportunity for theft. This underscores the importance of: 🔒 Robust, easy-to-use locking solutions that encourage proper use 🔒 Training and awareness for facility staff and users 🔒 Integrating technology and design to reduce risk in high-turnover environments We see it as part of our mission to ensure that security solutions are consistently effective. Just like New Year gym-goers, security success is all about building habits and systems that last beyond the first few weeks. #MasterIt

The 2024‑25 U.S. ski season saw ~61.5 million skier visits, the second‑highest total on record. With that volume of activity, unattended gear is increasingly vulnerable. Key insights: ❄️ Most ski and snowboard thefts happen when equipment is left unattended at base areas or outside lodges. ❄️ Snowboards are particularly targeted, as they’re easier to grab and resell than skis. These trends highlight an important opportunity: innovative, reliable locking solutions can protect equipment, reduce theft, and let athletes focus on their sport, not their gear. Whether it’s high-quality cable locks or rugged, weatherproof locks, the winter sports market underscores the growing need for security solutions that combine convenience with performance.

The holiday season isn’t just busy for small businesses—it’s critical. According to studies, over 90% of small business owners say holiday sales are essential to their success, with many relying on this period to hit annual revenue goals. Consumers are expected to spend $263B this holiday season, with an estimated $109B going directly to small businesses. Shoppers are also increasingly “shopping small,” with 41% planning to buy from small businesses, up from 36% previously. But with increased traffic and higher sales come higher risks: 🔒 56% of small business owners anticipate theft during the holidays, with many expecting losses to rise compared with other times of the year. 🔒 More foot traffic and cash handling can unintentionally create opportunities for shoplifting and fraud. 🔒 Holiday staffing dynamics—like temporary workers and stretched teams—can leave security practices less consistent and oversight more challenging. That’s where Master Lock solutions help small businesses stay focused: ✔️ Key lock boxes streamline access for owners, managers, and seasonal staff, ensuring security without slowing down operations. ✔️ Cash boxes protect daily earnings during the busiest and most critical season of the year. Simple, yet reliable systems give small business owners one less thing to worry about—so they can focus on serving customers and closing out the season strong.

Travel prep is all about the little things 😏, and education on the extent of what "TSA‑approved" really means is one of the most important. "TSA‑approved” isn’t just a label — it’s an engineered access control protocol that balances screening efficiency with asset integrity. Master Lock, in partnership with Travel Sentry®, designs TSA‑Approved locks that: 🔒 Allow airport security to open, inspect, and relock luggage without damage 🔒 Are recognized in ~29 countries, supporting consistent handling standards globally 🔒 Carry the Red Diamond logo, signaling compliance at over 650 airports for billions of travelers annually Technically, our locks feature: 🔒 Solid metal bodies, hardened shackles, and shrouded designs 🔒 Combination and keyed variants for flexible operational use 🔒 Up to 10,000 possible combinations, enhancing security in shared environments TSA‑Approved locks are controlled access components in a broader security ecosystem. Understanding their purpose helps reduce forced entry, preserve transported assets, and improve handling predictability; especially during peak travel times like the holidays. For teams managing travel, logistics, and corporate mobility, Master Lock TSA‑Approved locks demonstrate how standards-driven physical controls complement procedural protocols; and why educating teams and travelers about proper use is just as important as the hardware itself.
