Choosing between two physical license keys starts with the software they unlock. The Simplex 741-780 USB dongle is built for Simplex fire alarm software, while the Datacard ID Works Standard v6.5 package is an identification card suite with a CD and USB dongle. They are not interchangeable, so the decision is really about your workflow.
Quick verdict
If your job involves Simplex fire alarm software, the Simplex 4120/4100 TSW USB dongle key (part 741-780) is the specialized hardware key to weigh. If you need photo ID or identification card software, the Datacard ID Works Standard v6.5 package bundles the installation disc and a SafeNet Sentinel USB dongle at a lower listed price. These two physical license keys don't compete on the same job, so the choice comes down to the software ecosystem you already use.

Where each option stands out
- The Simplex dongle is the only option tied to a fire alarm environment. The title names Simplex, 4120, 4100, TSW, and the part number 741-780, so if you service Simplex panels, this is the direct match.
- The Datacard ID Works package stands out for ID creation. The Standard Edition includes advanced ID program capabilities, open database connectivity, and proximity card plug-ins, plus the physical CD and USB dongle.
Product notes
Simplex 4120/4100 TSW security USB dongle key 741-780
The Simplex key is a used USB security key with the exact part number 741-780 in the title. It is the higher-priced option at USD 1,200.00, and it is aimed at Simplex fire alarm software rather than general-purpose software. The item states that it is unknown whether the key unlocks the 4100 programmer, the 4120 programmer, the TSW True Site Workstation programmer, or the TSW Runtime operations. That uncertainty is the main limitation. Because the item does not specify which program this key opens, you need to know which Simplex tool you are trying to access before choosing it. For someone working with Simplex 4100/4120/TSW fire alarm systems, this is the more targeted option.
Datacard ID Works Standard v6.5 with USB dongle key
The Datacard package is an opened, pre-owned copy of ID Works Standard version 6.5, and it includes the original case, installation CD, inner setup instructions, and the mandatory SafeNet Sentinel USB security dongle. For identification card work, the Standard Edition includes advanced ID program capabilities, including open database connectivity (ODBC) and proximity card plug-ins. This is the lower-priced option at USD 699.99. The limitation is that this is an ID issuance suite, so it won't help if you need a Simplex fire alarm key. It also relies on the included CD and USB dongle for activation, which makes it a complete physical media package rather than a key alone.
Final choice by use case
Choose the Simplex 741-780 dongle if you are working with Simplex 4100, 4120, or TSW fire alarm software and you want a physical USB key from the same model family. The uncertainty about which tool it unlocks is the trade-off to accept.
Choose the Datacard ID Works Standard v6.5 package if you need to issue ID cards and want a complete software-plus-key bundle with the installation CD, instructions, and SafeNet Sentinel USB dongle. It also carries the lower listed price of the two.
