Smart Keeper UL03PKYL — USB Port Lock | Essential, 6 locks, Yellow

6 locks + keyUSB-A portsEssential seriesYellow

The Smart Keeper UL03PKYL is the USB Port Lock from Smart Keeper’s Essential series: 6 yellow locks that push into unused USB Type-A ports, supplied with the key that releases them. Each lock is fitted by hand, with no tools, software or power, and can only be released with a Smart Keeper Lock Key Basic (U03) of the matching colour code. In practice it stops files being copied to a USB stick, keeps unknown USB devices off reception PCs, classroom machines and kiosks, and keeps dust out of ports you do not use. Smart Keeper makes the keyhole smaller than 0.5 mm, so the lock cannot be picked out with a paper clip or similar tool.

Compatibility — check before buying:
Keys are colour-coded: Smart Keeper codes each lock colour to the key of the same colour, and the U03 key belongs to the Essential series — it does not open the Essential Mini locks, which use the U04 key. It fits USB Type-A ports only — not USB-C, USB-B or Mini-USB, which have their own Smart Keeper locks. Not sure it fits? Send us the device model and we check it.

Best For

✓ Reception and kiosk PCs
✓ Classroom and lab computers
✓ Point-of-sale terminals
✓ Thin clients and servers
✓ Shared office desktops
✓ Marking controlled ports by colour

Key Features

 
Fitted by hand
No tools, software, drivers or power — the lock goes straight into the USB-A.
 
Key-only release
Only a Smart Keeper Lock Key Basic (U03) with the matching colour code releases the lock.
 
Key in the box
The key comes with the locks, so you can start straight away.
 
Visible control
A coloured lock shows at a glance that the port or device is controlled, and a missing one stands out.

Frequently Asked Questions

Is the key included?
Yes. The key comes in the pack with the locks. Keep it with your IT kit — Smart Keeper sells the Lock Key Basic (U03) separately if you need a spare.
Does one key open every Smart Keeper lock?
No. Smart Keeper codes each colour to its own key, and the Essential series uses the U03 key. The Essential Mini locks (HDMI, SD and others) use the U04 key instead. Tell us which Smart Keeper locks you already use and we match them.
Does it fit USB 3.0 ports?
Yes, USB 3.x ports use the same USB Type-A shape. It does not fit USB-C — Smart Keeper sells separate locks for USB-C, USB-B and Mini-USB. Send us the model if a port sits deep inside a case.
Is it a replacement for software controls?
No. It physically stops casual plugging-in and makes controlled ports visible. For full protection, combine it with device-control policies in your operating system or endpoint software.
Singular Expert Insight
We suggest the UL03PKYL as a ready-to-use start for closing spare USB-A ports: six locks and the key in one pack, enough for a couple of reception or classroom PCs. Keep the key in IT and stay with one colour per team or zone, because keys do not cross colours. Physical locks work best alongside USB device-control policies. Every order comes with Singular’s local support in Cyprus. See our security products or the desktop accessories they protect.

Buyer’s Guide

Buy it if

You want to close up to six USB-A ports and need the key in the box.

Skip it if

Your ports are USB-C, or you already hold a yellow U03 key and only need more locks.
