This system is based on the Texas Instruments fixed code transponder. The onboard computer cannot be programmed without a working pre-programmed transponder key. Duplicate keys can be programmed into the system as long as there is at least one working pre-programmed key available. The system can accept a maximum of 6 different keys
Because the coding of the keys is proprietary and is protected by copyright law, cloning is not possible at this time for this system. Until Texas Instruments agrees to license this technology, the only way to program duplicate keys will be by the process outlined below.
Key blanks: Ilco / Silca TOY40BT4, Denso ebay keys available (and work reasonably well!)
Replacement key blanks can be ordered through any Lexus dealer.
Programming Steps:
1. Enter the car and close all doors. Simultaneously depress and release both the brake and accelerator pedals.
2. Within 5 seconds, insert the working pre-programmed key into the ignition and cycle the ignition from the "off" position to the "on" position 5 times. Leave the ignition in the "on" position.
3. Within 15 seconds, open and close the driver’s side door one time.
4. Within 20 seconds, open and close the driver’s side door 5 more times.
5. Within 20 seconds, remove the working key from the ignition.
6. Within 10 seconds, insert the newly cut transponder key into the ignition, and turn the ignition to the "on" position.
7. Leave the new key in the ignition for at least 60 seconds.
8. After 60 seconds the programming should be complete.
9. If you are programming additional keys, insert the next key within 10 seconds of removing the last, and turn the ignition to the "on" position. Once again, leave the key in the “on” position for at least 60 seconds.
10.Start the vehicle to verify that programming has been successful.
