12. Anti-hijacking
when the vehicle is running, the user gets off the vehicle then closes the
door well, and takes the remote control away. The device will try to detect
the remote control signal after 30 seconds, if it is still unable to detect
the remote signal in 1 minute, the alarm will warn with siren chirps and turn
signal flashes and the vehicle engine will cut off automatically in 40
seconds.
Pressing any button on the remote will cause the siren to chirp.
If press unlock button **, will disarm the device and detect the signal of
the key fobs. If unable to detect the signal of the remote control, the device
will set into lock status automatically.
13. Alarm triggered by illegal door opening/ foot brake
When the vehicle is in arm status if the vehicle door is opened illegally or
the foot brake is stepped on illegally, it will trigger the alarm, and the
siren will chirp for 25 seconds and turn signal light flash at the same time.
14. Central door locking automation
Starting the vehicle, close the door well, step on the foot pedal, and the
central door will automatically lock the vehicle door after 15 seconds. Once
the vehicle is stopped & engine is turned off, the central door will
automatically unlock.
When a vehicle is running and there is a passenger get off the vehicle, close
the door well, and stop on the foot pedal to start the vehicle, the central
door will automatically lock the vehicle door after 15 seconds.
When the vehicle is running, press unlocks button **once will unlock the
central door system.
Turn on/off central door locking automation:
Start the vehicle, open vehicle doors, quick step on the foot brake 5 times in
5 seconds, siren chirps once will turn off the central door locking automation
function; when the siren chirps twice mean turn on the central door locking
automation function.
15. Intelligent power off In arm status
While the system is in armed status, the power of the start system will be
cut off and you can’t start your vehicle even with the original vehicle key.
16. Door unlock well warning
When the user walks away from the vehicle with a remote control but does not
properly close the door well, the turn signal will flash 3 times, and the
siren chirps 3 times to
remind the user to close the door well. If the door is still not well closed,
the siren will chirp for 25 seconds, and the turn signal light will flash for
25 seconds to remind the user after 30 seconds.
17. Emergency override
If the remote control was lost, the user needs to do an emergency override in
order to use the vehicle. The step is as below:
Using the mechanical key to unlock the vehicle door (may trigger the alarm),
then open the vehicle door, keep stepping on the foot brake pedal, hold
pressing the programming button on the control module for 5 seconds will
emergency override the alarm, siren chirps 3 times and turn signal light flash
3 times to confirm. the vehicle is disarmed now.
Users need to turn on ACC, ON, or start the vehicle in 2 minutes after
emergency override, or the device will set into arm status again.
If the push start button is failed or defective, the user can step on the foot
brake pedal and continue to press the programming button 5 times to start/shut
off the vehicle.
Important: once the vehicle is an emergency override, all the alarm
functions will lose at the same time.
18. Power saving & vehicle battery low power protection
Once the remote control has not been used for more than 36 hours or the
vehicle battery is lower than 11.8V, the system will enter into sleep mode
automatically and turn off the PKE function to save power.
19. Vibration alarm warnIng(optIonal)
After the alarm is in arm status for 30 seconds, any hit or force on the
vehicle will trigger the alarm, and the siren chirps 5 times, turn signal
light flashes 5 times at the same time. If the device is triggered again in 30
seconds, the siren chirps 25 times and the turn signal light flashes 25 times
at the same time.
Only the version with the shock sensor has this feature. The alarm is default
without a vibration sensor and has no vibration alarm function. If users want
to equip with a vibration sensor, please contact us.
20. Programming method

Important: When you need to prolong any data set, you need to enter the parameter setting first, after you finish setting, please remember to exit the setting.
Central door locking installation
The alarm default setting is type B negative (-) for locking and unlocking, if
your car is with type B negative central door locking, you can connect the
white locking wire and white-black unlocking wire from EC003N with your car
locking and unlocking wire directly, or follow with the Type B negative
trigger as below diagram shows to connect with the car central door locking
system.
There are 8 different types of door lock systems (Type AH). Please search the
vehicle-specific wiring instructions online and the chart below to help
determine which door lock system your vehicle uses. Most vehicle factory door
lock wires are smaller gauge and located in the driver’s kick panel or under
the driver’s dash.
Note: The most common type of door lock systems are Type A positive trigger,
Type B negative trigger, and Type C reverse Polarity.
Type A: Positive trigger with three-wire (+) pulse controlling factory lock
relays.
Type B: Negative trigger with three-wire (-) pulse controlling factory lock
relays.
Type C: Reverse polarity, positive triggered
Type D: Adding one or more aftermarket actuators. These include central
locking systems without an actuator in the driver’s door, but with factory
actuators in all the other doors. Type D also includes vehicles without power
locks, which will have actuators added.
Type E: Electrically-activated vacuum systems. The vehicle must have a vacuum
actuator in each door. Make sure that locking the doors from the driver’s or
passenger’s side using the key activates all the actuators in the vehicle.
This requires a slight modification to the door lock wire harness.
Type F: One-wire system: cut to lock, ground to unlock.
Type G: Positive (+) multiplex. One wire control lock and unlock using a
resistor(s).
Type H. Negative (-) multiplex. Same as Type G system, but uses (-) pulse
instead.
TYPE A POSITIVE TRIGGER
Type A: positive trigger with three-wire (+) pulse controlling factory lock
relays.
There are 3 wires (+) pulse controlling factory locking relays, one pulses 12v
for lock, one pulse 12V for unlock, and the last one is for constant 12V.
Extra 2 SPDT relays are required.
TYPE B NEGATIVE TRIGGER
Type B: Negative trigger with three-wire (-) pulse controlling factory lock
relays.
Two wires resting open circuit, one pulses ground for lock and the other pulse
for unlocking.
For this kind of trigger, the vehicle switch will have three wires on it, one
wire will test ground all the time. One wire will pulse (-) when the switch
locks the doors, and the other wire will pulse (-) when the switch unlocks the
doors. This type of system is difficult to mistake for any other type.
Type C Reverse polarity, positive triggered
Motor interrupt central locking:
Two wires resting at the ground, one pulse 12V for lock, the other pluses 12V
for unlocking Direct-wired reversing-polarity switches. The switches are wired
directly to the motors. This type of system has no factory relays. Extra 2
SPDT relays are required. ****
Type D: Adding one or more aftermarket actuators
For this type of vehicle, there isn’t a motor in the driver’s door (central
locking only operates from the driver’s door). An extra door actuator is
required.
These include central locking systems without an actuator in the driver’s
door, but with factory actuators in all the other doors. Type D also includes
vehicles without power locks, which will have actuators added. Vehicles
without factory power door locks require the installation of one actuator on
each door. This requires mounting the door lock actuator inside the door.
Other vehicles may only require one actuator installed in the driver’s door if
all door locks are operated when the driver’s lock is used.
Type E: Electrically-activated vacuum systems.
Polarity reverses on a single wire to lock and unlock. Please set the door
lock time to 3.5 seconds by a timer delay switch (not included).
The vehicle must have a vacuum actuator in each door. Make sure that locking
the doors from the driver’s or passenger’s side using the key activates all
the actuators in the vehicle. This requires a slight modification to the door
lock wire harness.
The door locks are controlled by an electrically activated vacuum pump. The
control wire will show +12v when doors are unlocked and (-) ground when
locked.
NOTE: For this kind of central door locking, must program the clock pulse time
to be 3.5 seconds.
Type F: One-wire system: cut to lock, ground to unlock.
This type of central door locking system is mainly for Japanese-driven
Single wire in the series negative trigger.
The single wire pulses negative to unlock, and open the circuit to lock. This
type of door lock system usually requires a negative pulse to unlock and
cutting the wires to lock the door. (for some vehicles, these are reversed). 2
extra SPDT relays are used to interface to this type of system.
Type G: Positive (+) multiplex. One wire control lock and unlock using a
resistor(s).
Single wire positive central locking
Single-wire, positive lock, positive unlock.
Two potential (resistor may require) positive riggers.
Single-resistor style: if one resistor is used in the door lock
switch/key cylinder, the wire will pulse (+) 12V in one direction and less
than + 12V when operated in the opposite direction.
Two resistor types: if two resistors are used in the factory door lock
switch/key cylinder, the switch/key cylinder will read less than + 12V in both
directions.
Determining the proper resistor values: to determine the resistor values,
the door lock switch/key cylinder must be isolated from the factory door lock
system. For testing. use a calibrated digital multimeter that is set to ohms,
IMPORTANT: to ensure an accurate resistance reading, do not touch the
resistor or leads during testing.
- Cut the output ire from the door lock switch/key cylinder in half;
- Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable constant +12V source. Some good constant + 12V references are the power input source to the door lock switch/key cylinder, the ignition switch power wire, or the (+) terminal of the battery.
- Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resistance in one direction, no resistor is needed for that direction.
- Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.

Type H: Negative (-) multiplex. Same as Type G system, but uses (-) pulse
instead.
Single wire negative central locking
Single-wire, negative lock, negative unlock.
Two potential (resistor may require) negative triggers.
Single-resistor style: if one resistor is used in the door lock
switch/key cylinder the wire will pulse ground in one direction and resistance
to ground when operated in the opposite direction.
Two resistor types: if two resistors are used in the factory door lock
switch/key cylinder, the switch/key cylinder will read resistance to the
ground in both directions. Determining the proper resistor values: to
determine the resistor values, the door lock switch/key cylinder must be
isolated from the factory door lock system. For testing. use a calibrated
digital multimeter that is set to ohms.
IMPORTANT: To ensure an accurate resistance reading, do not touch the
resistor or leads during testing.
- Cut the output wire from the door lock switch/key cylinder in half,
- Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable ground source. Some good ground references are the ground input source to the door lock switch/key cylinder, or the battery ground.
- Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resistance in one direction, no resistor is needed for that direction.
- Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.

Manual for releasing the steering lock:
-
Please check whether there is a steering lock in your vehicle or not, if yes, follow with the next step.
-
Copy a key blade with your factory’s original key blade and match them so that the copied key blade can start the car.
-
When finished matched, put the copied key blade into the ignition cylinder of the car, as the picture shows:
Method 1: turn the key to the “ON” position. **
****So that the steering lock can be turned around. Then cut and keep 1mm length of the copied key outside of the lock. See the picture:
-
Stick the push start button on the lock. (That is the reason for cutting the key.)
-
Attention: If there is a chip immobilizer in the factory’s original key or remote control, need to take out the chip immobilizer and hide it inside or near the ignition cylinder. Please refer to the installation of the chip immobilizer. If you can’t find the chip by yourself. Just hide the original key or remote control in or near the ignition cylinder. (Please remember to take out the battery of the remote if you do so).
-
Everything finished like the picture:
-
If you don’t want to cut the key for releasing the steering lock, you can drill a hole in the car near the steering and install the push start button like in the picture, but it will not convenient for you as you need to use the original key to release the steering lock every time you start the car.
-
Unplug the factory ignition wire harness to avoid which consume the vehicle battery power.
Method 2: Use a screwdriver and push it into the hole of the ignition
cylinder (see photo on the left), turn the ignition key to ACC position, then
pull out the key with force will take out the ignition cylinder. Then remove
wires from the ignition switch and put the push start button over the empty
key cylinder slot.
Important:
Only a qualified staff can do this as there is a risk to lock the steering
lock again if the operation is not correct. If you are not a qualified staff,
we recommend you to use method 1 to release the steering lock.
Installation of chip immobilizer
If there is a chip immobilizer in the original key fobs, please follow with
below method
Method 1:
- Take out the original induction coil from the ignition lock.
- Put the car’s original remote control (including the chip immobilizer) into the coil, and make sure the induction of the chip immobilizer and the coil are good.
Method 2:
-
Take out the chip immobilizer from the car OEM remote control.
-
Take out the original induction coil from the ignition lock.
-
Stick the chip immobilizer on the induction of the car coil, and make sure the induction of the chip and coil is good.
Reminder: Some chips with a weak signal are hard to start the car when put on the car’s original coil. Then need to add a coin or other metal pad underneath the chip to enlarge the signal of it (see above drawing)
Method 3:
Use an extra bypass module to bypass it, installation steps are as below: -
Put the whole remote control (take out the battery from the remote first) and include the chip immobilizer into the bypass module.
Note: if the size of the remote control is big, the user can put PCB or chip inside the bypass module. -

FAQs of EC003N
Dear Customer,
Thank you for purchasing this product. Here are some FAQs for your
reference, if there is any question about the products, we recommend you to
read the FAQs to find answers and solutions. If those FAQs are still not able
to help you fix the problem, you can also contact EASYGUARD LTD and we will
help you till everything is working well.
-
The car lock and unlock randomly, what is the reason?
This should be due to there being PKE induction blind area and cause the device unable to detect the PKE signal well, the solution is to adjust the PKE antenna placed position till you have a maximum PKE induction range. When placing the PKE antenna, make sure it is not touched by any metal products. -
When using the remote start function to start the vehicle, it keeps cranking, what’s the reason?
It should be due to the fuel pump wire not being well connected, which should connect with the fuel pump wire or oil path motor or sucker wire in the vehicle if you can’t find this wire in the vehicle. You can connect it with the tachometer wire or ignition 1 wire. -
When I attempt to start the vehicle, It starts but shuts off a few seconds, what’s the reason?
There are possible 3 reasons:
a. If there is a chip immobilizer in your car’s OEM key fob, you need to have an OEM key & also need to buy an extra bypass module in order to make the kits work well. you can buy it from the EASYGUARD sales rep if you need it.
If you don’t want to buy the bypass module, please take out the chip immobilizer from the car OEM key fobs and stick it somewhere around the ignition cylinder till you can start the car.
b. The fuel pump wire is not well connected, which should connect with the fuel pump wire or oil path motor or sucker wire in the vehicle, if you can’t find this wire in the vehicle. You can connect it with the tachometer wire or ignition 1 wire.
c. The engine starting/cranking time is not enough. If so, you need to prolong the start time. Refer to parameter prolong setting instruction in the user manual. -
Does the alarm with anti-hijacking function?
Yes, the alarm default is with the anti-hijacking function. -
How to do programming?
Please refer to the programming method in the user manual. -
Is there a GWR (ground while running) wire? Or how to connect with a GWR wire to the alarm?
