Issue & Fix: KEYDIY KD-MAX shows the following error during programming: “Unable to recognize!
1. Change the position of the remote or lift the remote by half a centimeter and regenerate.
2. If method 1 does not work, please remove the battery and regenerate app:v8.8.5 firmware: 0.107.02.67, ID:289123”
The issue occurs when generating KD TDB03-3 Smart Remote Key for Toyota Avensis F433, where the first key can be generated successfully, but the second key fails, and the remote shows no response with no frequency detection and no red indicator blinking; the fix is to adjust battery insertion timing during generation.
Solution
1. Remove the battery from the KD TDB03-3key before starting the generation process on KD-MAX.
2. Wait until the KD-MAX system prompts button operation during generation.
3. Reinsert the battery at the prompt stage and continue the generation process.
Final Result
KD-MAX successfully recognizes and completes the generation of the KD TDB03-3 smart remote key for Avensis F433 after applying the correct battery timing during programming.
