Physical USB Port Security

The Syba SY-ACC20165 kit provides four red blockers that insert into standard USB sockets to prevent unauthorised device connections. A single dedicated key locks and removes each blocker, giving administrators physical control over port access. It suits offices, schools or shared workstations where removable media or charging cables must be restricted.

Replacing Software-Only Controls

This hardware solution replaces reliance on operating-system policies or BIOS settings that can be bypassed or reset. The jump is worth it when a tamper-evident barrier is required for compliance or data-loss prevention. It does not address network-based data transfer, so environments needing only logical port management may not benefit.

Simple Tool-Free Installation

Each blocker pushes into a port by hand and locks with a quarter-turn of the supplied key; no drivers or configuration are needed. The only common issue is misplacing the sole key, which renders all four blockers permanent until a replacement is sourced. Keeping the key in a managed location avoids this problem.

Questions about this item

How many USB ports can the four red locks cover at once?

The four included locks each occupy one standard USB Type-A port, so you can block up to four ports simultaneously.

What is the correct way to insert and remove a lock using the single key?

Insert a lock into the port, push the key into the lock until it clicks to secure it; to remove, re-insert the key, turn, and pull the lock straight out — forcing it without the key damages the port.

If the single key is lost, can additional keys or replacement locks be obtained?

The set ships with only one key matched to the four locks; Syba does not sell separate keys or lock packs for this model, so keeping the original key safe is essential.
