EASYPAY/SPEEDPASS INTERFERENCE WITH SMART KEY SYSTEM

In some cases, when customers fuel their vehicles at service stations that use the Antenna-style Easypay/Speedpass system, the customer may experience poor performance of the Smart Key system. Improvements in the system have been made to correct the following symptoms:

- Remote Keyless Entry (conventional wireless transmitter) functions intermittently inoperative.
- Keyless ignition function intermittently inoperative.

NOTE:
- During the above conditions, the customer can always use the "Hard" key shank to unlock the doors and can start the ignition by inserting the key head into the ignition cylinder.
- This TSB addresses the above complaints only.
- Some interference from strong electrical signals (including Easypay / Speedpass) may still occur. Please refer to the owner's manual for additional information.

APPLICABLE VEHICLES:
- 2004 model year Prius vehicles with the Smart Key System produced BEFORE the Production Change Effective VINs shown below.
