The lock interfaces directly with the security slot built into these devices for secure attachment.
What does 'master keyed' mean for this lock?
Master keyed refers to a locking system where multiple individual locks can be operated by a single master key. This allows security administrators to manage numerous locks across an organization with one key, simplifying key distribution and control. Individual locks still function with their unique keys, but the master key provides override access for authorized personnel.
How long is the security cable?
The cable measures 7.5 feet (2.29 meters) in length. This provides sufficient reach to secure Surface tablets to desks, tables, or other fixed structures while maintaining enough slack for comfortable device use. The length accommodates various anchoring scenarios in different environments.
Is this lock TAA compliant?
Yes, the Kensington K68139M is TAA (Trade Agreements Act) compliant. This compliance indicates that the product meets sourcing requirements for U.S. government contracts and many institutional procurement programs. TAA compliance ensures the lock is manufactured in or substantially transformed in a designated country, making it suitable for government and educational purchasing.
What warranty coverage does this cable lock include?
Kensington provides a 5-year limited warranty for the K68139M cable lock. This warranty covers defects in materials and workmanship under normal use conditions. The extended warranty period reflects the product's durability and provides long-term assurance for organizational investments in security hardware.
Can this lock be used with devices other than Surface tablets?
The K68139M is specifically designed for Microsoft Surface Pro and Surface Go tablets with compatible security slots. While it might physically attach to other devices with similar security slots, Kensington only certifies compatibility with the listed Surface models. For optimal security and proper fit, use only with supported Surface devices as specified.
What connectivity or interface options are available?
Connectivity details help confirm how the product integrates with your network, accessories, and surrounding peripherals before rollout or replacement planning. They are often the difference between a technically compatible device and one that is genuinely easy to deploy.
