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. On Avalon, Camry Solara, Land Cruiser and MR2 up to 4 ignition key identification codes be may registered in the ECM at one time. On Camry models produced from January 2003 and later, Highlander and 4Runner, only up to 4 ignition key codes can be made: 3 master ignition key identification codes and 1 sub-key ignition key identification code may be registered in the ECM at one time. On Camry models produced before January 2003, RAV4, Sequoia and Sienna, up to 3 ignition key identification codes may be registered in the ECM at one time. For all models except Camry models produced after January 2003, Land Cruiser and 4Runner, in automatic registration mode, the last ignition key to be registered becomes the sub-key. For Camry models produced after January 2003 and 4Runner, the registration order is not specified because the transponder key ECU can distinguish keys types. On Land Cruiser, master and sub-key codes are registered automatically.
NOTE:
A master key is a Black-colored ignition key and a sub-key is a Gray-colored ignition key.
- Ensure SECURITY indicator light is flashing. SECURITY indicator light is displayed as a vehicle icon near the center of the tachometer.
- Insert ignition key into ignition lock cylinder. Note that SECURITY indicator light should now remain on steady. On Camry models produced after January 2003, Land Cruiser, Sequoia and 4Runner models SECURITY indicator light should turn off when ignition key is inserted into ignition lock cylinder.
- On all models, 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 ignition key registration was complete, and system is operating normally, SECURITY indicator light should flash when ignition key was removed from ignition lock cylinder. 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, 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.
- On Avalon, Camry models produced before January 2003, Camry Solara and Highlander, 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.
- On Camry models produced after January 2003 and 4Runner, to forcibly complete automatic registration mode when at least one key code for the master key has been registered turn ignition switch from ON position to OFF position 5 times within 10 seconds using the already registered master key.
- On Land Cruiser and Sequoia, to forcibly complete registration mode when at least one key code for the master key has been registered, turn ignition switch from the LOCK position to the ON position 5 times within 10 seconds using the already registered master key. If using hand-held tester, select 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.
