| Metric | Observation | |--------|-------------| | Speed | Reading a transponder ID takes < 2 seconds. Writing a new key typically takes 5‑7 seconds. ECU flash (when used) averages 2‑3 minutes depending on file size. | | Success Rate | With a compatible vehicle and clean hardware connection, success rates reported by users are 90‑95 % for standard key duplication. Failure cases often stem from poor contact on the OBD port or a damaged transponder chip. | | Error Handling | Clear error codes (e.g., “0x01 – No CAN response,” “0x08 – Authentication failure”). The software will automatically retry up to three times before prompting the user. | | Stability | No crashes reported in the last 12 months for the Windows 10/11 builds. Occasionally, a USB power‑fluctuation can cause the program to reset; using a powered USB hub mitigates this. |


  • Security Risks – The software can write directly to immobilizer modules. An accidental overwrite can lock a vehicle out, requiring dealer‑level re‑programming (costly for the customer). Always double‑check VIN and key data before committing a write operation.

  • Intellectual Property – TrueCode’s database is proprietary. Redistribution of the database files is prohibited.

  • Bottom line: Use TrueCode only if you are a licensed professional or you have explicit permission from the vehicle owner. Never attempt to duplicate keys for a vehicle you do not own or have no authorization to service.
