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 LS 430 vehicles with the Smart Key System produced BEFORE the Production Change Effective VINs shown below.

IMMOBILISER REGISTRATION:
2. Erasure of Key Code
a) Erase key codes using the hand-held tester.
HINT:
- All key codes are erased except for the master key, which is used for erasing the key codes. In order to use a key whose code has been erased, the key code must be re-registered.
- Registration will be cancelled if each step is not completed within the specified time.
HINT:
- A brief outline of procedures for key code erasure is shown. For more detailed information, please refer to the hand-held tester screen's instructions.
- When the immobiliser system is operating normally and the key is pulled out, the security indicator starts blinking.

- When the key slot or the key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other keys.
NOTE:
When the key slot has been replaced, locking and unlocking doors is possible with the new master key's transmitter module (taken from the original master key). However, the new master key will not be able to lock and unlock doors through the door key cylinder. Keep the original master key. If the new master key's transmitter module's battery fails, the original master key can be used to lock and unlock doors through the door key cylinder.
