2023-2025 Toyota Camry Smart Key Immobilizer Reset TSB

Toyota has released Technical Service Bulletin (TSB) T-SB-0013-24 Rev1 to provide updated procedures for managing smart key systems across a wide range of its vehicles, including the 2023-2025 Toyota Camry. This TSB details the steps for performing a Smart Key Immobilizer Reset, adding new keys, and permanently erasing lost or stolen keys from a vehicle's system. These procedures are critical for vehicle security and functionality, especially when all master keys are lost or when specific keys need to be removed from the vehicle's memory.

This bulletin, dated March 4, 2024, is Revision 1 and supersedes the previous Service Bulletin No. T-SB-0064-18. The applicability has been expanded to include numerous 2025 model year vehicles, and updates have been made to various sections of the procedure, including the security authorization process and required tools. Any previous printed versions of bulletin T-SB-0064-18 should be discarded as it is now obsolete.

Important Warnings for Owners

Toyota outlines several critical warnings within this TSB that owners should be aware of:

• "When performing a Smart Code Reset, ALL registered keys are erased and CANNOT be used again on ANY vehicle." This means any existing keys will become unusable after a full immobilizer reset.
• "For Undesignated Key Permanent Erasure utility, ONLY the keys that are NOT present will be removed. ANY keys that are NOT present can never be reused." If you are removing specific keys, ensure that all keys you wish to keep are physically present during the procedure.
• "If ALL keys are lost, refer to the applicable Repair Manual and follow the process for establishing communication. It may also be necessary to maintain communication during the entire procedure by actions such as pushing the doorjamb courtesy switch or flashing the high beams. Do NOT cycle the engine switch to keep the ECU awake." This highlights the complexity and specific requirements for initial communication when no keys are available.
• "It is required to select AT LEAST two managers. Each request MUST receive approval by one manager." This applies to the security authorization process for dealers.
• "If the battery is low of charge, attaching a battery charger may be necessary to maintain battery voltage during Immobilizer Reset." This ensures the vehicle's electrical system remains stable during the procedure.
• "The battery diagnostic tool MUST be used in Power Supply Mode to maintain battery voltage at 13.5V while flash reprogramming the vehicle." This is a critical requirement for successful key programming.
• "When this function is performed, all the registered keys will become obsolete and can never be reused." This warning is displayed during the Smart Code Reset process.
• "Do NOT resubmit another approval for this vehicle if the file from management has been received in TIS and it shows the approval status for the given VIN." This prevents redundant requests during the security authorization process.
• "AFTER selecting Next, another passcode will be requested." This indicates that multiple passcodes may be generated during the process.
• "Make sure ALL keys to be reused are present." This is a crucial step before initiating the Undesignated Key Permanent Erasure.
• "The keys which are not designated will be deleted completely and can never be re-registered." This warning is displayed during the Undesignated Key Permanent Erasure process.
• "The keys that have not been touched to the Engine switch will be deleted and can never be re-used. Those keys can never be re-registered." This reiterates the permanent nature of key erasure if they are not physically presented during the Undesignated Key Permanent Erasure.
• "There is a 30-second timer for this procedure." This indicates a time-sensitive step during the Undesignated Key Permanent Erasure.

Symptoms

This TSB addresses situations where vehicle owners might experience issues with their smart key system. The primary symptoms or conditions requiring these procedures include:

• Lost ALL Keys: When all master keys for the vehicle are lost, requiring a complete immobilizer reset to register new keys.
• Add NEW Keys to Vehicle: When an owner wishes to add additional smart keys to their vehicle's system.
• Key(s) is (are) Lost or Stolen and/or Request to Remove ANY Key NOT Present From the Vehicle: When specific keys are lost or stolen, and the owner wants to permanently remove them from the vehicle's memory to prevent unauthorized access.

Warranty Information

Repair Procedure Summary

The TSB outlines three main procedures, all of which involve a stringent security authorization process through Toyota's Technical Information System (TIS) and Global Techstream (GTS+) software. This process requires manager approval and the generation of unique passcodes.

1. Immobilizer Reset (for Lost ALL Keys)

This procedure is used when all master keys are lost, necessitating a complete reset of the vehicle's immobilizer system. The process involves:

1. Security Authorization: Technicians must log into TIS and navigate to the Immobilizer Reset section. They re-enter their TIS password, complete the Immobilizer Reset form, and acknowledge the Positive Identification Policy. This step requires confirming approving managers.
2. Manager Approval: An approving manager logs into TIS, accesses the Approval Request Inbox Message, confirms the request details, acknowledges the Request Approval Policy, and approves the request.
3. Requestor Action: The technician (requestor) logs back into TIS, accesses the Approved Inbox Message, confirms details, and selects the "Immobilizer Reset" link. They re-enter their TIS password to proceed.
4. GTS+ Connection and Passcode Generation: The technician connects GTS+ to the vehicle. If the ignition cannot be turned on or information doesn't auto-populate, they manually select the vehicle model and year and enter the VIN in all capital letters. They then select "Smart Code Reset" from the Utility menu in GTS+.
5. Warning Acknowledgment: The system displays a warning: "When this function is performed, all the registered keys will become obsolete and can never be reused." The technician must check "I agree" and select Next.
6. Driver's Door Confirmation: The driver's door must be opened. The technician checks "I understand" and selects Next.
7. Passcode Retrieval: The technician selects "Get Pass-Code" in GTS+, which displays a seed number (e.g., "c8f0e0e517c75ffe80722878dd1e02172ed31b8e7022d8a59c3c2ac1045136c5b321aad566211a535b282b61ca625ccf"). This seed number is copied.
8. TIS Passcode Input: The technician selects "Send" to open a TIS link, where they enter the seed number to retrieve the unique passcode (e.g., "073082" or "A1A3B0ODA03ED"). This passcode is then copied and pasted into the "Pass-Code Number" box in GTS+.
9. Reset Execution: After selecting Next, a confirmation message appears: "It will take about 16 minutes for the reset to complete. Do you want to start the Smart Code Reset?" The technician selects Yes. The system then displays "NOW RESETTING KEEP DRIVER'S DOOR OPEN." Once complete, the message "Smart Code Registration may now be used to register Smart Keys" appears. The technician selects Exit.

This process ensures a secure 2023-2025 Toyota Camry Smart Key Immobilizer Reset.

2. Smart Code Registration (for Adding NEW Keys)

This procedure allows technicians to add new smart keys to the vehicle's system after an immobilizer reset or when additional keys are desired. The steps include:

1. System Access: The technician selects "Smart Code Registration" from the Utility menu in GTS+.
2. Instruction Review: They read the on-screen instructions, which include warnings like "Do not carry two or more keys into the vehicle. This may cause the function to fail," check each item, and select Next.
3. Passcode Retrieval: Similar to the immobilizer reset, a seed number is generated in GTS+, copied, sent to TIS, and a passcode (e.g., "A1A3B0ODA03ED") is retrieved and entered back into GTS+.
4. Key Space Check: The system displays the "Number of available spaces for new codes" (e.g., 6). The technician confirms there is enough room for the new key(s) and selects Next.
5. Key Placement: The currently registered key and any NEW unregistered key(s) are placed outside the vehicle. Then, one registered key is brought into the vehicle.
6. Pre-Start Check: The technician selects Next, touches the ignition switch with the registered key, and then selects "Pre-Start CHK" to review the registration process. The TSB emphasizes: "Pre-Start CHK MUST be selected BEFORE continuing to the next step."
7. Registration: After reviewing the Pre-Start CHK, it is closed, and Start is selected. The technician then touches the ignition switch with the NEW key. The vehicle will beep twice after each key is registered. This step is repeated until all new keys are registered.
8. Function Check: All registered keys are function-checked by pressing buttons (lock/unlock/panic/trunk) and ensuring the vehicle starts.
9. Completion: The technician can select Next to restart the process for another key or Exit to close the utility.

3. Undesignated Key Permanent Erasure (for Removing Lost/Stolen Keys)

This procedure is used to permanently remove specific keys that are lost or stolen from the vehicle's memory. This is a critical security measure for a 2023-2025 Toyota Camry Smart Key Immobilizer Reset.

1. System Access: The technician selects "Undesignated Key Permanent Erasure" from the Utility menu in GTS+. A note reminds them: "Make sure ALL keys to be reused are present."
2. Warning Acknowledgment: A warning is displayed: "The keys which are not designated will be deleted completely and can never be re-registered." The technician selects Next.
3. Key Count Input: The technician inputs the number of customer keys that are present (e.g., 1). The system displays the "Vehicle Keys" count (e.g., 2). They confirm the number of keys to be kept/deleted and select Next.
4. Final Confirmation: A final warning appears: "The keys that have not been touched to the Engine switch will be deleted and can never be re-used. Those keys can never be re-registered." The technician checks "I agree" and selects Next.
5. Passcode Retrieval: Similar to the other procedures, a seed number is generated in GTS+, copied, sent to TIS, and a passcode (e.g., "A1A3B0ODA03ED") is retrieved and entered back into GTS+.
6. Key Touching Process: The technician touches each key to be kept to the ignition switch one at a time. The vehicle will beep once per key.
7. Key Deletion: After all desired keys have been touched, the technician selects "Delete" to permanently remove all keys that were NOT touched to the ignition switch. A note indicates: "There is a 30-second timer for this procedure."
8. Completion: The system confirms: "Undesignated Key Permanent Erasure is complete." The technician selects Exit.
