PRODUCT DESCRIPTION
NanoSaver MasterKey Cable Lock from Lenovo (4XE1B81917) - Singapore Local Warranty
Fleet Security, One Key for Admins
The NanoSaver MasterKey Cable Lock from Lenovo is built for IT-managed deployments. Lenovo specifies it requires the MasterKey 4Z10P40249 (sold separately), giving administrators one key for every lock in the fleet.
Designed for Thin Devices
It carries a single NanoSaver lock head. The NanoSaver head is a tough 10 mm head with cleat locking technology that rotates and pivots for easy key insertion.
Anti-Pick and Cut-Resistant
Hidden Pin technology helps resist picking, while the 1.8 m (6 ft) carbon steel cable with plastic sheath resists cutting.
5 mm Keying
The 5 mm keying system is compatible with Lenovo's 5 mm keying systems, including MicroSaver 2.0.

Compatibility & Fit
Nano Slot, Not Kensington Slot
NanoSaver locks fit the smaller Nano security slot used on many recent thin Lenovo notebooks and other devices. They do not fit the classic rectangular Kensington Security Slot; for those devices choose a Kensington MicroSaver 2.0 lock, or the NanoSaver Twin Head Nano/MS 2.0 Cable Lock (4XE1B81919), which has one head for each slot type.
MasterKey Required — Sold Separately
MasterKey locks are designed for IT-managed fleets. Lenovo specifies that this lock requires the MasterKey 4Z10P40249, which is ordered separately, so one administrator key can open every lock in the deployment.
Check Your Device
Lenovo provides a compatibility checker on Lenovo Accessories SmartFind. Confirm whether your device has a Nano security slot or a classic Kensington slot before ordering.
