Laserline 921T User Manual

SELF-LEARNING PROCEDUREOPERATING INSTRUCTIONS

LASERLINE model 921T immobiliser is a sophisticated
electronic device for vehicle protection, which ensures very
reliable protection with a simple operation procedure.The
system consists of a Control unit, LED, Reader and two
contactless coded electronic identification devices called
TRANSPONDER.

The 921T immobiliser deactivates the main electric circuits
of the vehicle (starter solenoid, petrol pump, injection or
ignition coil...) and simply operates by a coded
TRANSPONDER KEY that must be moved to a reader,
usually fitted behind the vehicle dash fascia before starting
the vehicle.

Activation of the system is automatically carried out
approximately 20 seconds after switching the ignition off.
Once activated, a dash fascia mounted LED will flash.

From now on, the immobiliser operates on two
specific points of the vehicles starting-ignition
or fuel supply systems, to prevent an
unauthorised attempt to start the vehicle.

To switch the immobiliser off, move the coded
TRANSPONDER KEY to the reader and remove. You have
approximately 20 seconds to start the vehicle. If you fail to
start the vehicle within this 20 seconds the system will re­activate automatically and it will be necessary to move the
coded TRANSPONDER KEY to the reader and remove
again in order to start the vehicle. Note: always switch OFF
the immobiliser before switching ON the ignition key as
accidental activation of Self-Learning Procedure may
occur. If accidental activation of Self-Learning Procedure
does occur, wait for LED to flash at a rate of 1 flash per
2 seconds before disarming.

All the wires of the immobiliser are black and are
recognisable by a code printed on the end of them. When
the installation is completed, all the codes on the ends of
the wires are removed so that they are not identifiable and
the immobiliser cannot be neutralised.

There are thousands of millions of combinations
for the TRANSPONDER KEY, so each key is
unique and cannot be replicated. When one of
the 2 supplied TRANSPONDER KEY is lost, it is
necessary to execute the SELF-LEARNING PRO­CEDURE.

Note

After the above operations, any lost or stolen TRANSPONDER KEYS become useless.
Code memorisation can only occur when the LED is constantly on. No more than 10 seconds must elapse
between memorising each TRANSPONDER KEY.
When 4 TRANSPONDER KEY have been memorised, the immobiliser will automatically exit from the self­learning procedure or 10 seconds after the last TRANSPONDER KEY was memorised.
If a new TRANSPONDER KEY has been memorised, it is necessary to memorise the original TRANSPONDER
KEYS if their continued use is desired.
If only one TRANSPONDER KEY is available no SELF-LEARNING PROCEDURE will take place and the
procedure will enter EMERGENCY CODE (PIN CODE) DISPLAY PROCEDURE.
To memorise only one TRANSPONDER KEY follow the “USING THE EMERGENCY CODE (PIN CODE) TO
DISARM THE IMMOBILISER” procedure and memorise single TRANSPONDER KEY.

1) Deactivate the immobiliser by moving the
TRANSPONDER KEY to the reader location.

2) Turn ignition key to ON position.

3) Move and hold one of the TRANSPONDER KEYS

to the reader.

4) Maintaining the TRANSPONDER KEY over the
reader, turn OFF the ignition key.

5) Remove the TRANSPONDER KEY from the
reader.

6) Check if the LED is steady ON, as indication of
the beginning of SELF-LEARNING PROCEDURE.

7) Within 10 seconds of the LED remaining ON,
move over the reader a new/spare
TRANSPONDER KEY, followed by the original
TRANSPONDER KEY first used to enter the
SELF-LEARNING PROCEDURE. Each KEY
learning is signalled by a short pause of the LED

8) When the 10 seconds from the last
TRANSPONDER KEY as elapsed, the
immobiliser exits from the SELF-LEARNING
PROCEDURE and displays the EMERGENCY
CODE (PIN CODE) via flashing of the LED.

9) Note the PIN CODE in the space provided at the
end of these instructions.

Verify that all TRANSPONDER KEYS operate;
otherwise, repeat the above steps.

EMERGENCY CODE (PIN CODE) DISPLAY PROCEDURE

To display the PIN CODE, activate the self-learning procedure and wait 10 seconds for the LED to switch
OFF. The immobiliser will use the LED for displaying 5 sequences of flashes that will correspond to 5

numbers. The following table shows an example of a PIN CODE and the corresponding LED flashes:

On the above example, the PIN CODE to note at the end of these instructions would be 5 6 0
5 4.

It is imperative to note on a piece of paper this Emergency Pin Code, if it is different from the original pin
code displayed in the rear of these instructions. This pin code must then be stored in a secure location. Note:
If you intend to leave these instructions in the vehicle, the pin code in the back of these instructions should
be removed for safekeeping.
This emergency code is derived from the first TRANSPONDER KEY memorised when you self-learn a
new TRANSPONDER KEY. If you want to change the pin code from the original code, you may have to
follow the self-learning procedure more than once alternating the first TRANSPONDER KEY until a new

pin code is given.

HOW TO DISARM THE IMMOBILISER

USING THE “EMERGENCY CODE”

If the TRANSPONDER KEYS do not work correctly or have been lost, to disarm the immobiliser you must insert
the “EMERGENCY CODE” (PIN CODE) as follows:

1) With the immobiliser ON, turn ON the ignition key.

2) The LED will now flash at a rate of 10 seconds ON, 2 seconds OFF, 10 seconds ON, 2 seconds OFF etc.

3) At any point when the LED is OFF, switch the ignition OFF. (If you miss the 2 second period whilst the

LED is OFF the LED will again come on for 10 seconds).

4) The LED will start to flash and the immobiliser is ready to accept the PIN CODE. If not interrupted, the
LED will flash 10 times. Turn ON the ignition key for 1 second after the LED as displayed the flashes
corresponding to each digit of your PIN CODE, read PIN CODE at the end of these instructions from left
to right. For a better understanding, see the example.

If the inserted PIN CODE is correct, the immobiliser will disarm itself and automatically enter the “SELF­LEARNING PROCEDURE”, signaling this condition by LED ON for 10”. Follow SELF-LEARNING PROCE­DURE from step 6. If the inserted PIN CODE is wrong, the immobiliser will remain ON.
