2013 SSANGYONG KORANDO key battery

When deleting the old code of the transponder registering an extra ignition key, please attend on
the site and observe the process personally.
In any cases, the immobilizer system cannot be removed from the vehicle. If you attempt to remove
it and damage the system, starting will be impossible. So never attempt to remove, damage or
modify it.
The remote engine starter cannot be installed to the vehicle equipped with the immobilizer system.
Do not drop the key or subject it to impact the key, as it may damage the transponder inside the
key.
The engine cannot be started using a key with damaged transponder.
In the following cases, you may experience starting problem or a system error can occur. 1.

5) Cautions for immobilizer
When two or more ignition keys come into contact with (each) other(s), or the key is close to any
device that sends/receives electromagnetic fields or waves.
When the ignition key is close to any electromagnetic device, such as lighting equipment, security
keys or security cards.
When the key is close to a magnetic, metal object, or battery. -

1. OVERVIEW
The SKM (Smart Key Module) system is equipped to only the vehicles with smart key and is to prevent
theft and enhance the driver experience. When the driver presses a door handle switch carrying a smart
key, this system checks the smart key information and driver door status and locks/unlocks the doors
(passive function). The vehicle can be started when the driver enters the vehicle and presses the
START/STOP switch (passive start function).

(4) Smart key battery discharge warning (3) Smart key verification fail warning
When the verification is requested for ignition status change or engine starting and no verified smart key
is in the vehicle, the SKM sends the "smart key verification status" signal, which indicates that the
verification has failed, for up to 10 sec. until the verification fail conditions are deactivated. for up to 10
seconds. until the verification fail conditions are deactivated.
Verification fail detection and transmission conditions
When the ignition status is changed after a smart key is verified by the START/STOP switch ON
input, the SKM sends the verification status for 10 sec. -Normally, the smart key verification warning is one of the smart key fail conditions. -
Ignition status change
(OFF -> ACC) / (OFF -> IGN)/(ACC -> IGN) / (IGN -> engine ON) *
If above conditions are met again, the SKM re-verifies a smart key and sends the verification status
for another 10 seconds.
When the ignition status is changed by the transponder verification while the smart key status is sent
through the B-CAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 seconds. -
-
If low smart key battery is detected during the verification process for ignition status change or engine
start, the SKM sends the signal for "smart key battery low voltage warning" to the BCM and instrument
cluster through the B-CAN for up to 10 sec. until the warning condition is deactivated.
Smart key battery discharge confirmation and deactivation
If the smart key battery low voltage is confirmed, the SKM sends the smart key battery low voltage
warning signal.
If the smart key battery is in normal condition, the SKM sends the smart key battery low voltage
warning deactivation signal.
The smart key is the last used key. -

(5) Transponder verification fail warning
If a verified smart key is not found by the key verification process, the SKM sends the information that
indicates the key is not verified to the instrument cluster through the B-CAN for up to 10 seconds until
the warning condition is deactivated.
The SKM sends the transponder verification warning when the verification has failed with the smart
key inserted into the immobilizer holder. -
Transponder verification fail detection and transmission conditions
When the ignition status is changed after the transponder is verified by the START/STOP switch ON
input, the SKM sends the transponder verification status for 10 sec. -

(10) Brake not working alert
The SKM sends the brake not working alert signal for 10 sec. every time the ignition status is changed
after the 1st cycle (OFF-ACC-IGN-ACC-OFF)
while the brake is not operated.
when the brake pedal is depressed, the system is reset and alert deactivation signal is sent.
when the 10 min. timer is terminated -

(11) Smart key slot detection alert
The SKM sends the smart key slot detection alert signal for 10 sec. when a smart key inserted into
the slot is detected with IGN OFF and the driver's door open. -

12. SKM IMMOBILIZER SYSTEM
1) System Description
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the engine.
The transponder inside the key communicates with the SKM (immobilizer slot) and EMS (ECU) through
P-CAN communication, and the system permits the engine to start after confirming the encrypted
coding.
When the START/STOP switch is pressed with the smart key inserted into the immobilizer slot because
of the smart key battery discharge, the SKM communicates with the EMS (ECU) through P-CAN, and
the ECU starts to control the engine only the signal is valid.
A valid key verification time is provided for 10 seconds and the engine can be started during this time. If
pressing the START/STOP switch again after this 10 seconds, the key verification process is performed
again.

Door lock/unlock control by door LOCK switch
When moving the driver or passenger door lock (knob) switch to LOCK from UNLOCK position, BCM
sends the LOCK signal for 0.5 seconds.
When moving the driver or passenger door lock (knob) switch to UNLOCK from LOCK position, BCM
sends the UNLOCK signal for 0.5 seconds.
The LOCK (UNLOCK) operation by the door lock (knob) switch is not available when sending the
LOCK (UNLOCK) signal by any other method such as remote control key.
When reconnecting the battery, the door lock (knob) switch is not operational regardless of the door
lock switch positions.
All doors stay unlocked when receiving the door lock signal in 0.5 seconds after closing the doors. 1.
