Quick take
Physical license media hardware keys force a simple but high-stakes question: which used USB dongle belongs in your software setup? The four keys in this guide cover three very different ecosystems. The Simplex 741-780 targets fire-alarm programming and operations software; the Micros E7 key targets point-of-sale software; and the two FARO keys target 3D scanning, metrology, and measurement software. Listed prices run from USD 10.00 to USD 5,579.07, so the real decision is not just budget but matching the dongle to the software it is meant to unlock. Start by identifying your software platform, then use the comparison table to narrow the field.
A used dongle only helps when it matches the software module you need, so the first filter should be software family rather than price. The Simplex key is tied to fire-alarm controllers and TSW, the Micros key is tied to E7 point-of-sale software, and the FARO keys are tied to 3D scanning and measurement software. From there, the dollar spread separates single-purpose keys from larger software investments.

Product notes
Simplex 4120 4100 TSW Security Software Hardware USB Dongle Key Sentinel 741-780
The Simplex dongle is positioned for fire-alarm software security: the title pairs it with the 4120 and 4100 controllers plus TSW, and the part number is 741-780. At USD 1,200.00, it sits in the middle of the four options. Choose it when you need a used sentinel-style USB key for a Simplex fire-alarm environment. The limitation is clear: it is unknown whether this key unlocks the 4100 programmer, the 4120 programmer, the TSW programmer, or TSW Runtime. That means the right choice depends entirely on the specific Simplex software you need to access.
MICROS E7 Software License Key 100074-279 USB Dongle
At USD 10.00, the MICROS E7 key is the most accessible physical license media hardware key in this group, and it is listed by i-UayBiQri. It is identified as a used E7 software license key with model USB Software Security Key and MPN 100074-279. The item is marked as a non-modified, no-custom-bundle unit, so you are getting a straightforward dongle rather than a packaged set. Choose it if you are building out a Micros E7 workflow and want the lowest-cost entry point. The limitation is that no compatibility scope is shown beyond the E7 model name, and the key is used.
FARO Software License Key USB Dongle Portlock HASP (SOFTS0302 & SOFTS0371)
The FARO Portlock HASP key is described as an authentic, genuine FARO software license key USB dongle for activating proprietary FARO 3D scanning, metrology, or measurement software modules. It includes the original protective storage case and the factory key. At USD 4,799.20, this is the lower-priced FARO dongle in the comparison. Choose it when you need FARO software activation and want the key delivered with its intended case. The limitation is the high purchase price, especially because the dongle is used and you are relying on the physical key's condition.
FARO 3D Scanner Software License Key USB Security Dongle (SOFTS0302 & SOFTS0371)
The second FARO dongle uses the 3D scanner framing in its title and carries the same SOFTS0302/SOFTS0371 references. It also includes the original protective storage case and the factory key. At USD 5,579.07, it has the highest listed price among the four options. Choose it if you prefer the 3D scanner wording and want a FARO USB security dongle for the same scanning, metrology, or measurement software types. The limitation is cost: this is a used key with a higher listed price than the other FARO dongle in this roundup.
Final recommendation by use case
- Simplex fire-alarm software: The Simplex 4120 4100 TSW dongle is the only option tied to Simplex fire-alarm systems, but its use depends on the specific programmer you need to unlock.
- Low-cost Micros E7: The MICROS E7 Software License Key at USD 10.00 gives you a used E7 dongle without extra bundled components.
- FARO 3D scanning and metrology: The FARO Software License Key USB Dongle Portlock HASP at USD 4,799.20 is the lower-priced FARO choice; the FARO 3D Scanner USB Security Dongle at USD 5,579.07 is the alternative for the same part references with the scanner-oriented name.
