Lenovo Kensington NanoSaver Keyed Cable Lock · 1.8 m
Nano slotKeyed, 2 keys1.8 m steel cable10 mm lock head
The Kensington NanoSaver Cable Lock from Lenovo (4XE1L51710) is a keyed laptop lock with a compact 10 mm lock head that anchors ultra-thin laptops, tablets, desktops and monitors built with a Nano security slot to a desk or fixed object. It suits offices, classrooms and front desks that want a simple, key-controlled theft deterrent for current thin-and-light ThinkPads and similar devices.
The NanoSaver uses Kensington's Cleat locking technology and a 5 mm keying system with hidden-pin anti-pick protection, on a 1.8 m carbon steel cable with a pivoting and rotating head.
Before you order: Fits devices with the Nano security slot only. If your laptop has the larger standard Kensington slot or a wedge slot, this lock will not engage.

What It Means in Practice

Singular Expert Insight · Buyer's Guide
Keyed or combination is mainly an admin decision: keys suit managed fleets where IT controls access, combinations suit shared desks where keys get lost. Either way, confirm the slot type first. If laptops sit on a dock, see our
docking stations; many have their own lock slot too.
✓ Buy it if your device has a Nano security slot and you prefer key control.
✕ Skip it if your laptop has a standard K-slot or a wedge slot.
→ Also consider Kensington NanoSaver Combination Cable Lock (4XE1F30277) for keyless use.
