Trouble Diagnoses
If no doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.
Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains
a valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and
allow key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.
