2. KEY REGISTRATION IN AUTOMATIC REGISTRATION (NEW REGISTRATION)
(a) When an ignition key is inserted into the ignition cylinder, the key code (immobilizer code) registration
is automatic. In this mode, a maximum of 4 key codes for 3 master keys and 1 sub-key can be regis-
tered. Any order of registration for the master keys and sub-keys is fine because the transponder key
ECU can distinguish between different types of keys.
HINT:
When a new transponder key ECU is installed, key codes (immobilizer codes) must be registered with
ignition keys.
New transponder key ECUs are automatically set to automatic key code registration mode.

HINT:
When no key is inserted in the ignition key cylinder in automatic key code registration mode, the securi-
ty indicator remains on.
When the immobilizer system is operating normally and the key is pulled out, the security indicator
blinks continuously.
If the key code registration has failed in automatic key code registration mode, code 2-1 will be output
from the security indicator. Trying to re-register an already registered key will cause code 2-2 to be
output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 will
be output from the security indicator. The output details are shown below.
(b) Finish the automatic key code registration mode.
The automatic key code registration mode can be forced to end when at least 1 key code (immobiliser
code) for the master key has been registered.
(1) Turn the ignition switch ON and OFF 5 times within 10 seconds using the already registered mas-
ter key.
