Registration Of Additional Keys (Without Using Scan Tool)

Additional ignition keys can be registered without using the scan tool by operating two ignition keys that already have been registered to the vehicle and operating an additional key to be registered. A maximum of 8 ignition keys can be registered. To register additional keys without using scan tool:

1. Using a key (Key A) which has already been registered to the vehicle, turn ignition switch to ON position. Leave Key A in ON position for about 5 seconds. Turn ignition off, and remove Key A.
2. Using a second key (Key B) which has already been registered to the vehicle, turn ignition switch to ON position. Leave Key B in ON position for about 5 seconds. Turn ignition off, and remove Key B. Key B must be turned on within 7 seconds of removing first key.
3. If Key B is correct, immobilizer-ECU enters additional key entry mode. Theft-alarm indicator light in instrument cluster blinks about twice a second. After theft-alarm indicator light begins to blink, turn ignition switch to OFF and ON positions using new transponder key. Time during which new key can be registered is limited to less than 30 seconds after theft-alarm indicator blinks.
4. To register another key, turn ignition to OFF position. Place ignition key to be registered in ignition switch, and turn key to ON position within seven seconds. To add additional keys, repeat procedure. A maximum of 8 ignition keys can be registered. Additional key registration mode is terminated when any following condition is met:
   • Ignition key is in ON position more than 30 seconds (time-out of addition entry mode).
   • Engine control relay is off after key is turned to OFF position.
   • Start communication with scan tool.
5. Ensure additional registered keys can start engine, after ignition is turned off and engine control relay is turned off.
