To register keys into a new/virginized ECU:
1. Security light should be blinking, indicating that the ECU is in
registration mode.
2. Insert a key into the ignition (do not turn). The security light should
now be solid, indicating the key has been registered. Wait 15 seconds.
Remove key from the ignition.
3. Repeat step #2 once more.
4. Insert a 3rd key into the ignition (do not turn). The security light should
extinguish after a few seconds. Do not turn the key.
5. Remove the key from the ignition. If the security light is still
illuminated, pump the brake pedal 5 times to exit registration mode.
The first 2 keys are registered as MASTER keys, the last key becomes
the VALET key.
Tip: If you would like to program only 1 key, cycle the key through the
registration process 4 or 5 times.
