NOTE: Steps 2a, b, & c MUST be done in close time and sequence together in order for the test to be
performed correctly.
2a. Open the door, enter the vehicle, and then close the door. Press the ignition button, and then immediately
perform step 2b.


At this time, due to no Intelligent Key in or around the vehicle, the BCM will activate only the ignition
switch antenna.

Ignition switch antenna will become
active and will transmit a signal to detect
any Intelligent Key in range

Figure 3
2b. WITHIN 30 SECONDS of step 2a above, FIRST have an associate hand the Intelligent Key to you, THEN
immediately perform step 2c.
Have an associate deliver
the incident Intelligent Key
WITHOUT HAVING TO
OPEN THE DOOR
Figure 4
2c. Place the Intelligent Key next to the ignition button as shown in Figure 5 below (emblems align with center
of buttons). Do not depress the ignition button.

Place Intelligent Key next to
ignition button and wait for tones
Figure 5


If two short tones are heard, the Intelligent Key was de-synchronized but is now
re-synchronized and should function normally again. See step 3, Figure 6 (next page).



If no tones are heard and the Intelligent Key buttons still do not work, refer to ASIST or
the applicable Electronic Service Manual for further diagnosis.
