Remote Transmitter

CODE LEARNING OR ADDING ANOTHER REMOTE.

1. Turn key to the On position.
2. Press and hold the valet button until the system chirps 3 times to indicate 
ready to learn status.
3.  Press button 1 of the first transmitter once. Then, press Button 1 of the 
second transmitter once. The siren will output a confirmation chirp(s) with 
each remote transmitter that is learned. For example, after the first remote 
transmitter is programmed, the siren will chirp once. After the second 
transmitter is programmed, the siren will chirp twice. Up to 4 transmitters 
can be programmed.
4. If only one remote transmitter needs to be programmed/added, the 
other remote transmitter(s) must be reporgrammed at this time.
5. When done, turn key to OFF position to exit code learning mode.

NOTE:

 If you place the system in learn mode and teach nothing, the system 

will exit in 10 seconds. If the 4 location limit is exceeded, the system 
erases the oldest codes.
The memory or the codes is NON VOLATILE and will not be erased by 
power failure for 10 years or more.

ARMING

Press button 1. Siren will chirp once, parking lights will flash once. The 
system will arm. In 5 seconds the system will enter arming mode and the 
starter/ignition kill circuit will be enabled. If button 3 is pressed within 
these 5 seconds, the system will chirp 3 or 2 times.                                                                    
2 Chirps: On light impact, the siren chirps 5 times. On heavy impact, the 
siren will sound for 60 seconds.
3 Chirps: On both light and heavy impacts, the siren will chirp 5 times.

DISARM

Press button 2.  The siren will chirp twice and the parking lights will flash 
twice. The system will disarm. The starter/ignition kill circuit will be 
disabled. If passive arming is selected, after 60 seconds the system will 
enter arming mode automatically (but will not lock the doors).

NOTE:

 If the alarm was triggered during armed mode, the siren will chirp 

3 times.

PANIC 

Press button 4 to enter panic mode. After 30 seconds the system will exit 
this mode and enter arming mode automatically, during panic mode press 
button 2 to exit.

SMART PASSIVE ARMING

This system will automatically arm in 60 seconds after you leave the vehicle 
(After turning off the engine, you may remain in the car indefinitely, without 
the system passively arming. The cycle begins when you leave the car). The 
60 second timer is reset each time a protected zone has been opened. The 
LED flashes rapidly at this time. To avoid locking your keys in the car, the 
system will not lock the doors.

TO DISABLE PASSIVE ARMING

Turn key to OFF position, then press 
and hold the valet button until the 
system chirps once. 

SHOCK SENSOR FEATURE

The shock sensor is built-in to the alarm’s main module. Mount the module 
tightly on a large wire harness or a stiff plastic plate under dash. Avoid 
mounting the module on metal surfaces because this will reduce the remote 
range. Also, avoid installing the module on the steering column. The shock 
sensor will be less sensitive to glass, and more to the tires.

To adjust the shock sensor:
1. Turn key to the ON position.
2. Hold the valet button until 3 chirps are heard.
3. Turn key to OFF position.
4. The system will chirp once.
5. Wait 2 seconds, then strike the "A pillar" firmly with your fist.
6. The system will chirp twice to indicate it has learned your new setting.
7. When done, turn key to ON position to exit code learning mode.
NOTE: The harder you strike the car, the less sensitive the alarm will be. 
The softer you strike the car, the more sensitive the sensor will be.
Do not set too sensitive, as the alarm will false trigger often. The system is 
NOT DESIGNED to detect rocking or swaying motion.

TO DISABLE THE SHOCK SENSOR

1. Turn key to the OFF position.
2. Hold the valet button until 1 chirp is heard.
3. Press button 2 once within 5 seconds.
4. The alarm will chirp to indicate shock sensor is on or off and save 
settings to the EEPROM.
5. The alarm will disarm.
2 Chirps: shock sensor is enabled.
3 Chirps: shock sensor is disabled

NOTE: 

Warning chirps will still be active.

VALET/EMERGENCY OVERRIDE BUTTON

To disarm the system in case of a lost remote transmitter, do the following:
1- Turn key to the ON position.
2- Press and hold the valet button. The system will disarm.

IGNITION TRIGGERED DOOR LOCKS

In order to protect the occupants, once the engine has been started, your 
doors will lock within 5 seconds. The doors will then unlock after the 
engine has been turned off.

OPEN TRUNK

Press and hold  button 3 for 3 seconds to open the trunk.
