Using the Techstream tool, connect to your vehicle’s onboard diagnostic port and access the immobilizer or smart key system.<>

Follow the on-screen prompts to begin the key erasure process. This typically involves:<>
- Selecting the “Undesignated Key Permanent Erasure” option

- Turning the key to the “ON” position
- Removing the key after the system recognizes it
Repeat this process for each designated key.<>
6. Confirm Erasure of Undesignated Keys
Once all designated keys have been verified, the system will ask you to confirm the erasure of all undesignated keys. This is typically an irreversible process, so ensure you’re certain before proceeding.<>

After confirmation, the system will erase all undesignated keys from the vehicle’s memory. This process may take a few minutes to complete.<>

Important Considerations and Precautions
When erasing undesignated keys from your Toyota vehicle, keep the following points in mind:<>
Professional Assistance
While some Toyota models allow for key erasure without specialized tools, many require professional equipment and expertise. It’s often best to have this procedure performed by an authorized Toyota dealership or certified locksmith.<>
Irreversible Process
The key erasure process is typically irreversible. Once undesignated keys are erased, they cannot be reactivated and will need to be reprogrammed if you wish to use them again.<>
Vehicle-Specific Procedures
The exact steps for erasing undesignated keys may vary depending on your Toyota model and year. Always refer to your vehicle’s manual or consult with a Toyota professional for model-specific instructions.<>

Alternative Methods for Older Toyota Models
For some older Toyota models without smart key systems, there may be alternative methods for erasing undesignated keys. These methods typically involve a series of steps using the ignition key and door locks. However, these methods are not as secure or reliable as the official Toyota procedure and should only be used as a last resort.<>
Example Alternative Method (for illustration purposes only):
- Insert a master key into the ignition and remove it 5 times within 15 seconds
- Insert the key a 6th time and leave it in the ignition
- Open and close the driver’s door 6 times within 40 seconds
- Turn the key to the “ON” position
- The security light should flash, indicating the system is ready to accept new keys
Note: This method may not work for all Toyota models and could potentially cause issues with your vehicle’s security system. It’s always best to use the official Toyota procedure or seek professional assistance.<>
