Sentinel Key Not Found Autodata 95%

The "Sentinel key not found" error in Autodata usually means the software can't detect the physical USB security dongle or the digital license required to run the program.

  • Legitimate user: Contact Autodata support directly. Have your dongle serial number (printed on the USB) and proof of purchase ready. They may replace a faulty dongle (often for a fee).
  • Second-hand dongle risk: If you bought a used dongle from eBay or a private sale, it may be blacklisted or damaged beyond repair.
  • Time to go online: Autodata now offers a cloud-based subscription (Autodata Online) with no dongle required. If your hardware dongle is dead, consider switching.

If it does, add an exclusion for the Autodata installation folder and the hasplms.exe file located in C:\Windows\System32. 6. Legacy Compatibility (For Older Autodata Versions) sentinel key not found autodata
