Smart Keeper DL04P1GN — DisplayPort Lock, 10 Locks, Green
10 locksDisplayPortKey not includedEssential Mini
The Smart Keeper DL04P1GN is a pack of ten green DisplayPort Locks — locks only, without a key, from Smart Keeper’s Essential Mini series. Each lock is pushed into an unused DisplayPort 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 full-size DisplayPort outputs and inputs on desktops, graphics cards, monitors, docks and signage players. 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 full-size DisplayPort only. It does not fit Mini DisplayPort (the smaller port on many laptops, Surface devices and older Macs) — that is Smart Keeper’s separate MD04 lock — nor HDMI or USB-C with video. 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 DisplayPort 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.
Will it fit Mini DisplayPort?
No. This is the lock for full-size DisplayPort. Mini DisplayPort needs the smaller Smart Keeper MD04 lock. The word Mini in the product name refers to the Essential Mini series, not to the port.
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 DL04P1GN 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 Mini DisplayPort Lock MD04, easy to confuse because both belong to the Essential Mini series; 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
PC monitors 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 DisplayPort 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 Mini DisplayPort. Check the port shape first — we help with that.
