The global semiconductor shortage is impacting service parts supply as well. Service parts should only be ordered on a case-bycase basis for customers who cannot operate their vehicles without a replacement key. Please do not order service replacement
parts to provide a second key to a customer at this time. Please refer any customers with extenuating circumstances to the
Brand Engagement Center for further support.
Until the Second Key Delivery Program is launched, dealers can use the FAQ below to answer questions for customers.
Thank you for your continued support.

MOTOR SALES, U.S.A., INC.
Frequently Asked Questions
Q1. What is causing this shortage?
A. The global semiconductor shortage is limiting the supply of Smart Keys for new Toyota
vehicles. In order to provide vehicles
as soon as possible to our customers, we are temporarily reducing the number of Smart Keys provided from two to one.
We will provide the second Smart Key to customers as they become available.
Q2. Why does this only apply to certain vehicle models?
A. Some vehicles have a different Smart Key that is not being impacted at this time.
Q3. Which models are currently being produced with only one (1) Smart Key?
A. Rav4 Prime, bZ4X, Venza, Prius, Prius Prime, Crown, Sienna, Tundra, and Sequoia.
Q4. How long will this shortage last?
A. We continue to work diligently to minimize the impact to our customers. At this time, we estimate that all models will return
to production with two (2) Smart Keys in the fourth quarter of 2023. Depending on the parts supply situation, we are
currently aiming to begin providing affected customers with their second Smart Key in phases beginning in June 2023. Refer
to the chart on page 2 for additional details.
Q5. How will Toyota
notify customers when their second Smart Key is available?
A. We plan to notify affected customers by first class mail when second keys are available and ask customers to return to a
Toyota
dealer with their vehicle and original Smart Key so dealers can program a new second key and provide it to the
customer. The mailing will also occur in phases, and the timing will be approximately one week after the announcement of
each phase.
Q6. Does a customer need to make an appointment with their dealer to get their second Smart Key?
A. Owners will be encouraged to make an appointment in advance to receive their second key so that the dealer can order
the appropriate key for the customer in advance. However, an appointment is not required if the dealership has the
necessary parts for the customer should they arrive without an appointment.
Q7. Do customers need to bring anything with them to their appointment to receive their second Smart Key?
A. Yes. Customers will need to bring the vehicle and original Smart Key equipped with their vehicle to their appointment. The
original key will be used to program the new Smart Key to the vehicle.
Q8. What if a customer has lost their original key?
A. If a customer has lost their only Smart Key, please provide them with a second key as a goodwill gesture. For other
extenuating circumstances, please have the customer contact the Toyota
Brand Engagement Center for further assistance.
Q9. What if a customer has additional questions or concerns?
A. If a customer has additional questions or concerns, please have them contact the Toyota
Brand Engagement Center at 1888-270-9371 Monday through Friday, 8:00 am to 8:00 pm, Saturday 9:00 am to 7:00 pm Eastern Time.

Q10. How will my dealership receive the parts to provide a second key to the customer?
A. As the number of models involved in this issue is large, there are over 30 different part numbers of Smart Keys involved in
this activity. To make ordering easier for dealers, your dealership will order parts through Campaign Parts Order Request
(CPOR) by VIN. The CPOR system will identify the exact part numbers and quantities that you need for each VIN input, and
you will be able to order in bulk with up to 20 VINs at one time.
Q11. Will Toyota
be pre-deploying a stock of parts for my dealership in advance?
A. Toyota
will strive to pre-deploy inventory of Smart Keys to each dealership to handle walk-in customers as much as possible,
consistent with parts availability. Please remember that there are many part numbers involved in this activity and some
part numbers have a very small number of affected vehicles associated with them. While it may not be possible to predeploy inventory of every part number, Toyota
will do our best to provide you with a pre-deployment of parts as much as
possible.
Q12. How will the second key be priced?
A. A nominal price of $0.01 has been set for the second key given that the customer already paid for the value of the second
Smart Key when they purchased their vehicle.
Q13. Is the second Smart Key delivery part of Toyota
’s New Vehicle Limited Warranty?
A. No. The second key delivery is not considered part of Toyota
’s New Vehicle Limited Warranty. This is simply the delivery of
the second Smart Key that the customer already paid for, but which was unavailable at the time of the vehicle delivery due
to the ongoing chip shortage situation.
Q14. What is the difference between a Type #2 (15CY) and Type #3/#4 (19CY) Smart Key?
A. The Type #2 (15CY) and Type #3/Type #4 (19CY) Smart Keys have a different design and use different semiconductors. The
models that use these different types of Smart Keys are explained in the chart above. Due to differences in the supply of
the semiconductors used, the timeline for each type is different.
Q15. A customer recently had a new Smart Key registered to their vehicle and now there is a message on the MultiInformation Display (MID) about a new key being registered. Is this normal?
A. Yes. Depending on the model, a message may display for up to 10 days and is intended to provide the owner a notice that
a new key has been registered. This message is displayed to inform the owner that a new key has been registered and help
prevent the vehicle from being stolen if the registration was unauthorized. Refer to the Repair Manual or Owner’s Manual
for more information.
