Warranty Information

Smart Key ENTRY

When unlocking the vehicle's door using the Smart Key function, please note:

The system has been designed to have a two-step unlock process. To unlock the door:

1. Approach the vehicle (with a registered master key in your possession) and grasp the door handle.

2. After hearing the security system unlock confirmation, pull the handle open.

If the handle is pulled quickly (prior to the unlock confirmation), the door may NOT open on the first pull of the handle.

Smart Key RE-ENTRY After Locking

After the door has been closed and locked (by any method). Please note the following:

^ The Smart Key CANNOT be used to unlock the vehicle for 3 seconds after the doors are locked. This has been designed to allow customers to confirm that the door is actually locked by pulling the handle.

^ If the customer wishes to re-enter the vehicle before the 3-second time period has expired, the Remote Keyless Entry "UNLOCK" button can be used.

^ This time delay can be adjusted from 3 seconds, to 2, or 1 second through C-BEST, if desired.

Key Precautions

The Smart Key system has a unique key. Some important notes about this key include:

^ In some rare cases, equipment (located outside of the vehicle) operating on similar frequencies may affect the performance of the system. Should this occur, the Hard Key Shank (located within the Smart Key) can always be used to enter the vehicle, and the Smart Key can be inserted into the key slot, allowing the Power button to place the vehicle in "Ready" mode.

If the System Does NOT Work (Quick Checks)

In the event that the Smart Key system does NOT work, a few key checks should be made before proceeding with diagnosis.





1. Check to see that the Smart Key system is ON (verify that the On/Off switch under the dash is in the ON" position).

2. Verify that the conventional keyless entry system works (if NOT, check the key's battery voltage).

3. Move the vehicle to another location and try the functions again.

^ If none of the above corrects the condition, refer to the Technical Information System (TIS), applicable model year Prius Repair Manual:
