Step-by-Step Guide: All Keys lost Programming for Toyota 8A Using M822
- Open the Toyota software (version V26.90 or higher), navigate to: By Type – All blade Key lost (8A). The corresponding menu will appear.
- Select Read Immobilizer Data. You will be prompted to connect to the network and guided through vehicle connection. Refer to the “Wiring Diagram” for detailed instructions.
- Once properly connected to the vehicle, click OK. The device will extract immobilizer data—this process takes less than 3 minutes. Please wait.
- After data reading is complete, name the file and save it in the Adapter/Toyota folder.
- Disconnect the M822 Adapter and restore the vehicle to its original state.
- Ensure KC100/KC501 is connected, KS-1 is ready, and the device remains online. Click Generate 8A Simulated Key, then select the saved data file.
- Select a key position. Note that each position has an ID, but only certain positions contain a registered key. Typically, key positions 1 or 2 hold registered keys if none have been erased.
- Connect KC100 or KC501 to the device and insert the KS-1 into the slot. The emulated sub-master key will be generated.
- Test the emulated key by removing the chip from an unprogrammed key, placing the KS-1 near the ignition switch, inserting the key, and checking if the engine starts. The immobilizer indicator light should turn off. If unsuccessful, repeat steps 6–8 using a different key position.
- If the emulated key works, proceed to OBD Programming Function. With a valid sub-master key, the remaining steps are identical to adding a new key. It’s recommended to check the number of currently registered keys first.
Note: The emulated KS-1 key does not appear as a registered key and will not be counted in the total key count.
- Click Add a Key, follow the on-screen prompt, place the KS-1 near the ignition switch, insert the new (chipless) key, and turn the ignition on.
- When the immobilizer indicator light remains on steadily, turn the ignition off, remove the new key, install the chip, reinsert the key into the ignition (do not turn it on).
- The immobilizer indicator will begin flashing. Wait approximately 1 minute. If the light turns off, the key has been successfully added. If not, repeat steps 11–13.
- After completion, check the registered key count again and compare it with the previous count to confirm successful registration.
