Smart Keeper CL04P1GN — USB-C Port Lock, 10 Locks, Green
10 locksUSB-CKey not includedEssential Mini
The Smart Keeper CL04P1GN is a pack of ten green USB-C Port Locks — locks only, without a key, from Smart Keeper’s Essential Mini series. Each lock is pushed into an unused USB-C port by hand, with no tools, software or power, and stays there until it is released with a Smart Keeper key of the matching colour. In practice it stops someone plugging a cable or device into that port, and a green lock in a port shows at a glance that it is controlled. It fits USB-C ports on laptops, tablets, phones, docks and monitors. The pack contains no key, so you also need the green Lock Key Mini (U04) — we explain below. Because each colour has its own key pattern, a green key can be given to the people responsible for the green ports without opening locks of other colours, and the locks can be moved to another device with the key when needs change.
Compatibility — check before buying:
No key in this pack. Smart Keeper sells these locks without a key; they are released with the Lock Key Mini (U04). Keys and locks are colour-coded: Smart Keeper states a lock opens only with a key of the matching colour, so a green lock needs a green key. The Mini-series key is not compatible with Smart Keeper’s Basic series (USB-A and RJ45 port locks), so do not mix series. It fits USB-C ports only — not USB-A, micro-USB or Lightning. A locked port cannot charge, so leave free the USB-C port your laptop charges from. Smart Keeper’s Pro-series USB-C locks (CSK-CL04) look similar but use a different key. Not sure? Send us the device model or a photo of the port and we check it.

Key Features
Locks in by hand
Pushes into an empty USB-C port without tools, software or power, and stays there until released.
Colour-coded key
A lock opens only with a Smart Keeper key of the same colour, so each team or zone can hold its own colour.

Visible control
A coloured lock shows at a glance that the port is controlled, and an empty one shows a lock is missing.

Frequently Asked Questions
Is a key included?
No. This pack contains ten green locks only. You need the green Lock Key Mini (U04), sold separately. Order it together with the locks if you do not have one.
Will a key of another colour open it?
No. Smart Keeper states that locks open only with a key of the matching colour, and that Mini-series keys do not work with the Basic series. Tell us which Smart Keeper locks you already use and we match them.
Can I lock the USB-C port my laptop charges from?
You can, but a locked port cannot charge or connect a dock. Lock the spare USB-C ports and leave the charging port free, or charge through a dedicated power connector if the laptop has one.
Is it a replacement for software port control?
No. It physically blocks the port, which stops casual use and makes controlled ports visible. For full control, combine it with device-control policies in your operating system.
Singular Expert Insight
We offer the CL04P1GN as the refill for an Essential Mini installation — if you do not own a green Lock Key Mini (U04) yet, add one to the order. The mistake we see most is the Pro-series USB-C Port Lock CSK-CL04, which uses the Pro key instead of the Lock Key Mini; check the port first. Physical locks work best alongside software device control, and every order comes with Singular’s local support in Cyprus. See our
security products or the
docking stations they protect. If you already run Smart Keeper locks, send us a photo of one fitted lock or its packaging and we confirm the series and colour before you order.
Buyer’s Guide
Buy it if
You hold a green Lock Key Mini, or are ordering one, and need ten more USB-C locks. The locks weigh a fraction of a gram and sit almost flush, so they can stay fitted permanently.
Skip it if
You have no green Mini key and are not ordering one, or your port is USB-A. Check the port shape first — we help with that.
