Ignition Key Registration
NOTE:
In the case of having lost all the already registered master ignition keys, you are not able to do additional registration or deletion of ignition key codes. You must change the Engine Control Module (ECM) and then perform ignition key registration.
NOTE:
This procedure MUST BE performed ONLY when NEW Engine Control Module (ECM) is installed. A new ECM is in automatic registration mode and up to 3 ignition key identification codes may be registered in the ECM at one time. In automatic registration mode, the last ignition key to be registered becomes the sub-key.
NOTE:
A master key is a Black-colored ignition key that opens all locks. A sub-key is a Gray-colored ignition key that will not open the glove box.
- Ensure SECURITY indicator light is flashing. SECURITY indicator light is located near center of the instrument panel, just above the A/C controls. See Figure.
- Insert ignition key into ignition lock cylinder. Note that SECURITY indicator light should now remain on steady.
- Once ignition key registration is under way, SECURITY indicator light should turn off. After ignition key registration is complete, SECURITY indicator light should come on steady. Remove ignition key.
- If the registration was complete and system is operating normally when ignition key was removed from ignition lock cylinder, the SECURITY indicator light should flash. If ignition key registration was not completed with ECM in automatic registration mode, a code 2-1 will be displayed by SECURITY indicator light. See Fig 1. When inserting an already registered ignition key in ignition lock cylinder, a code 2-2 will be displayed by SECURITY indicator light. See Fig 1.
- If programming additional ignition keys, repeat process starting with step 1. If additional ignition keys do not need programming, procedure is complete. SECURITY indicator light should turn off once last ignition key (sub-key) is registered.
- To complete automatic registration mode, without removing or installing registered ignition key in ignition lock cylinder, depress and release brake pedal at least 5 times within 15 seconds, or request automatic registration mode completion by using Toyota hand-held tester connected to data link connector No. 3. Data link connector No. 3 is located at driver's side of instrument panel. See Fig 2.
