Smart Keeper MSD04P1GN — Micro SD Port Lock Essential Mini, 10 Locks, Green
10 locksmicroSD card slotKey not includedEssential Mini
The Smart Keeper MSD04P1GN is a pack of ten green Micro SD Port Locks from Smart Keeper’s Essential Mini series — locks only, without a key. Each lock pushes into an unused microSD card slot by hand, with no tools, software or power, and can only be taken out again with the Smart Keeper Lock Key Mini (Essential Mini series). In practice it stops a memory card being inserted to copy data in or out, and keeps an unused slot closed on shared, public and company equipment, and a coloured lock shows at a glance which ports are controlled. Smart Keeper sells the locks in colour-coded versions, so different teams or areas can be marked apart.
Compatibility — check before buying:
No key in this pack: Smart Keeper sells this 10-lock pack without the key. You need the Smart Keeper Lock Key Mini (Essential Mini series), sold separately, or the MSD04PK set, which comes with a key — without one, fitted locks cannot be removed. It is for microSD slots only — full-size SD card slots need Smart Keeper’s separate SD Port Lock. The Essential Mini locks are not the same system as Smart Keeper’s Professional Mini range (for example CSK-MSD04), which uses a different key, so do not mix the two. Not sure your port takes it? Send us the device model and we check it.

Key Features
Locks in by hand
Pushes into an empty microSD card slot without tools, software or power, and stays there until released with the key.
Key-only removal
Only the Smart Keeper Lock Key Mini releases the lock, so the port stays closed to casual users.
Ten per pack
Enough locks for the matching ports across a small fleet of devices, all opened with the same Mini key.
Visible control
A coloured lock shows at a glance that the port is controlled, and an empty port shows one is missing.

Frequently Asked Questions
Is a key included?
No. This is the 10-lock pack without a key. You need the Smart Keeper Lock Key Mini (Essential Mini series), sold separately, or the MSD04PK set, which includes a key. Order the key together with the locks if you do not have one.
Which ports does it fit?
It is made for microSD card slots on laptops, tablets, cameras, dashcams and embedded devices. It is for microSD slots only — full-size SD card slots need Smart Keeper’s separate SD Port Lock. Send us the device model if in doubt.
Does the Mini key open other Smart Keeper locks?
The Lock Key Mini is made for the Essential Mini series. Smart Keeper’s Basic locks use the Lock Key Basic and the Professional range uses its own keys, so keep to one series per installation.
Can the lock be removed without the key?
It is designed to stay in the port until released with the matching key. That is what stops casual use — so keep at least one key with IT.
Singular Expert Insight
We offer the MSD04P1GN as the refill for a Smart Keeper Essential Mini installation — if you do not own a Lock Key Mini yet, add one to the order or choose the MSD04PK set with key. Pick one colour per team or area, and combine physical locks with device policies for full control. Every order comes with Singular’s local support in Cyprus. See our
security products or
docking stations for the devices they protect.
