Ghost Vehicle Security

Protection from Key Cloning and Key Theft.

Ghost II

Protection from Key Cloning and Key Theft.

The Ghost II Immobiliser is a unique, next generation device that secures your vehicle without the need for cutting wires or adding aftermarket key fobs.

The device is connected to the vehicles CAN data network and a personalised PIN code is programmed into the Ghost immobiliser using buttons on the dash and steering wheel.

Engine start blocking

The Ghost immobiliser will prevent the starting of the engine unless the unique, user defined PIN code has been entered first.

Undetectable using diagnostics

A modern thief can use diagnostics to detect circuit cuts on modern vehicles. The Ghost has no circuit cuts so it cannot be found using these methods.

No radio frequency signals

Thieves cannot use sophisticated RF scanning, code grabbing technology to detect what security device your vehicle has when it does not transmit any signals like conventional security systems.

Advantages of using the CAN data network

The use of the CAN data bus has several advantages including low risk during installation, low probability of detection, and allows for placement almost anywhere in the vehicle.

Silent operation

The Ghost alarm communicates with the ECU on the data bus to immobilise the vehicle. There is no way a thief could listen for the tell-tale clicking of a traditional immobiliser relay

Stops key cloning and ECU swapping

A thief cannot simply add a new key or replace an ECU to bypass the Ghost and start the vehicle. Only a correct PIN code will allow the engine to start.

Tested for each vehicle

Due to the nature of the data bus communication the Ghost has been adapted and tested for every vehicle we list as compatible.

Weatherproof tiny device

The Ghost immobiliser is sealed and so small it can be installed and wrapped into the vehicle harness anywhere in the vehicle making it near impossible for a thief to find.

Emergency PIN code override

If the PIN code is forgotten, the car is sold or a button is broken there is a secure, unique reset code for each device.

Service / Valet mode

Service mode allows your vehicle to temporarily start and drive without requiring the PIN code. The Ghost will exit service mode based on speed and time.

Simple PIN code change process

At any time you can easily change the PIN code. Only you will know the unique PIN code for your vehicle.

Uses the vehicle’s original buttons to enter the PIN code

The buttons in modern vehicles send data all around the vehicle which allows us to detect many different keys being pressed without extra wiring

TASSA Verified
Ghost II is TASSA verified.

In order to make extreme security also be hassle free, we have created a smart-phone application that connects to your car and allows you to get in and drive without having to enter the disarm sequence to the fitted Ghost car alarm. This Ghost-II allows 2 phones to be connected. All you have to do is pair your phone with your Ghost immobiliser, leave the Autowatch Ghost-II application running in the background with Bluetooth enabled and you can drive conveniently and securely.

However, remember that if your phone is in range (5m to 10m) and the application is running the Ghost-II will be disarmed.

You can easily turn the app on and off by pressing the button.

Here are the most common questions answered. 

Service / valet mode allows you to hand over the keys to your car to someone without having to give them your disarm sequence. This way they get to know that your car is protected by the Ghost. Use this mode when you take your car for service or valet parking. Here are a few key points about service mode.

  • Allows for an indefinite amount for starts and drives without needing the disarm sequence
  • Turns off all key learning protection (this is still active when the Ghost is disarmed!)
  • Can be manually turned off
  • Will exit automatically when driven for a reasonable time

How to enter service / valet mode

  1. Disarm the system using your disarm sequence or mobile app
  2. Drive to, and park up at the dealership, airport, valeter’s etc and while the engine is still running, turn the app completely off then press your service button 5 times
  3. The indication lamp will flash back at you 5 times to confirm service / valet mode has been entered

How to exit service / valet mode manually

  1. Simply enter your normal disarm sequence (must have an ignition cycle since service mode was entered)
  2. There will be the normal disarm 2 flash confirmation
  3. The next time the ignition is switched off the Ghost will rearm as normal

How service / valet mode exits automatically

  1. Drive up to 31 mph (50 kph) 
  2. Continue to drive (at any speed) for 15 minutes
  3. Once the time as elapsed there will be 2 flashes to indicate that service / valet mode has exited

Note 1: If you switch off the ignition before the 15 minutes time has elapsed the Ghost will stay in service / valet mode

Note 2: Should you not know what your service button is contact us or your installation company

You can change your disarm sequence (PIN code) at any time. 

Before you start you need to know the following to complete the process successfully.

  1. What buttons are available on your vehicle - this information should have been given to you by your installer as there are variations between vehicle versions and specifications.
  2. Is your vehicle using the alternative to the accelerator input - check the list at the end of this article
  3. What is your indication signal and how fast does it react? Some vehicles have slow indications that are fine for normal operation but can be confusing when in sequence change mode
  4. Each button press needs to be within 2 seconds of the previous button press otherwise the Ghost will consider the sequence completed
  5. Some buttons are only active up to 5 seconds after the ignition has been switched on
  6. Some buttons require a long press (half a second) before activating, a short press will not register
  7. The disarm sequence can be between 4 and 20 presses of any of the working buttons and buttons can be repeated
  8. The service/valet button however can only be used 4 times in the disarm sequence
  9. Decide what you want your new sequence to be before starting this procedure!

To start the process you need to have either the normal disarm sequence or the emergency override code (on the card)

Using the normal disarm sequence

To enter sequence change mode you need to follow these steps

  1. Switch on the ignition without starting the engine
  2. Enter the current disarm sequence - 2 flash confirmation
  3. Press and hold the accelerator pedal to the floor
  4. Enter the current disarm sequence again - indication will start to flash once every 3 seconds, this means the Ghost is in learn mode
  5. Release the accelerator pedal
  6. Enter the new disarm sequence 
  7. Wait for 3 flashes
  8. Enter the new disarm sequence again
  9. 2 flashes confirms that the process was successful, 4 flashes means there was an error. If there was an error the disarm sequence will not be changed.

Using the emergency code

If you have forgotten to disarm sequence or it is not working for whatever reason you can use the emergency code on the black card that came with your Ghost. The number you are looking for is the 4 digit number under the scratch off area. To use this you need to follow the steps provided in the Emergency code help section.

Having problems with this?

  1. On new BMW (G chassis) there is no traditional ignition state, to enter the correct mode press quickly the start button 3 times until diagnostic mode is active and the instrument lamps become active.
  2. If the process is not successful you should always be able to use the old disarm sequence, this will not be erased at any point.
  3. Vehicles is alternative inputs for accelerator
    1. Porsche models before 2018 - press and hold the hazard switch to simulate the accelerator being pressed and held
    2. Some Audi / VW / SEAT / Skoda / Bentley - if the accelerator does not work use the high-beam flash (pull towards the driver)
    3. Some post 2017 Range Rover / Land Rover / Jaguar - if the accelerator does not work use the high-beam flash (pull towards the driver)
  4. On vehicle that use the accelerator as part of the disarm sequence you must move step 3 (press and hold accelerator) to the end of the disarm code repeat. 
  5. Ignition is defined at when all the instrument lamps turn on and back off and the car is fully active. On some vehicles it this might take 2 presses of the start button without your foot on the clutch or brake.

You can download the Ghost app to your phone, and this can disarm the vehicle when you enter the vehicle. 

Please note if you park your vehicle close to where you leave your keys (this is somewhere between 5 & 10 metres) the bluetooth signal may reach the car so could allow the system to deactivate when entering the vehicle.

We recommend either use the manual controls in your car or switch the ghost off when you leave your car.
