2. OVERVIEW
The functions of the immobilizer and the rechargeable key are controlled by the immobilizer &
rechargeable unit. Both functions are used in this system. This immobilizer & rechargeable unit
starts the engine by communicating with the engine control unit and increases the life of the
existing REKES battery by charging the battery of the remote control key.

3. FUNCTIONS OF IMMOBILIZER & RECHARGEABLE KEY
The functions of the immobilizer and rechargeable key are similar to that of the normal REKES
key. But, there are the immobilizer function that permits the engine to start only after confirming
the encrypted coding and battery charging function.
The followings are common functions of the normal REKES key and the immobilizer &
rechargeable key.
Door Unlock and Panic Function
Breifly press (below 0.5 sec): Door unlock and
　　　　　　　　　　　　 theft deterrent
mode deactivated
Press and hold (over 2 sec): Panic function
1. Door unlock (Briefly press)
If you send the door unlock signal using the
remote control key, with all the doors locked,
the door will be opened and the theft
deterrent mode will be deactivated. If the
door coupled switch of front room lamp is
pressed, the lamp will come on for 30
seconds. It will turn off immediately after the
lock button of the remote control is pressed.
2. Panic function: activated in the theft deterrent mode

4. START FUNCTION
1) Immobilizer Function
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 immobilizer installed in the key
box, and the system permits the engine to start after confirming the encrypted coding from the
engine ECU.
For the vehicle with the immobilizer, there can be a problem in starting the vehicle or the
system error:Immobilizer & rechargeable
unit sends encrypted code
to transponder (2)
Sends an encrypted signal to
unit as a response (3) Randomly transmitted code is changed
to an encrypted signal in immobilizer &
rechargeable unit (4)
System compares signal from
transponder and encrypted signal in
immobilizer & rechargeable unit (5)
When two or more immobilizer keys come into contact with (each) other(s).
When the key is close to any device sending or receiving electromagnetic fields or waves
other than Ssangyong products.
When the key is close to any electronic or electric devices such as lighting equipment,
security keys or security cards.
When the key is close to a magnetic or metal object or a battery. a.

Immobilizer and Warning Lamp ▶
This indicator comes on when the ignition key
is communicating with the engine control unit
(during engine starting) and goes out after
starting the engine.
When turning the ignition key to the "ON"
position, the ECU (engine control unit)
transmits the challenge message to the
immobilizer & rechargeable unit.
(This is to verify whether the key is valid. If the
verification fails, it transmits re-verification
signals 3 times for 2 seconds. If three re-
verifications fail, it stops verification and starts
re-verification after 10 seconds.) (1)
ECUOnly when the two signals are identical, it recognizes the
key as the authorized one and transmits the positive
message to the ECU. (6)
The ECU enable the engine to be started. (7)
Do not drop or shock to the transponder in the key as it may be damaged.
With a damaged transponder, the engine cannot be started.
When you erase the code or register an extra key, please attend on the site.
In any cases, the immobilizer system can not 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. ·

2) Rechargeable Key Function (Charging)
If the communication between ECU (engine control unit), immobilizer & rechargeable unit and
transponder is establisehd successfuly (engine started), the rechargeable Li-ion battery in the
transmitter is charged.
The charging is made by creating the mutual induced electromotive force in the antenna coil and
by supplying the charging current to the battery in the key. This charging is not resulted from the
direct contact but the induced electromotive force of the coil in the transmitter according to the
change of magnetic field. For details, see the below:
Primary magnetic
induction coil Secondary magnetic
induction coil
The single coil has both immobilizer
function and recharge function.
For the immobilizer function, if the
transponder confirms the key as the
startable key by communicating with the
ECU, it induces a magnetic induction in the
primary coil by passing through the current
with a certain frequency to the immobilizer
coil. The induced electromotive force
created in this way, is stored in the
chargeable battery through the commutator
and the circuit. Primary magnetic
