Firmware notes
Remote Start Ready (RSR):
•RSR installations are not compatible with vehicles equipped with a manual transmission.
•RSR is a function that enables the interface module to remote start the vehicle completely on its own
Consequently, there is no need for an aftermarket or an OEM remote starter in order to start the vehicle from a distance.
SmartStart Compatible: SmartStart is equipped with D2D, which means it can be connected to an interface module and used in
Remote Start Ready (RSR) mode without the use of a remote starter. See "Module programming" for more information.
Key2GO: Mandatory to control the immobilizer override in this firmware.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
Refer to the "Vehicle connections" following the installation diagram.
Footnotes
[1] Hood pin: The installation of an aftermarket hood pin is only required on vehicles that are not equipped with a factory
hood pin, or if not supported in data.
[2] RAP Off connection: If the RAP Off wire is not connected, the radio will turn off but some lights will remain ON in the
center console for 10 minutes. Connect the Green/Black wire (pin 2/12) to the vehicle driver door input to avoid this
issue. The RAP Off/Door input color and location can be found in the "Vehicle connections" section.
[3] Lock and Unlock Output wires: Only make these connections if the vehicle is not equipped with OnStar.

Key2GO
This feature is required if only one key is available. You can program the interface without the need for Key2GO if two keys
are present.
Key2GO has been designed and developed to bypass the advanced encryption layers found in modern vehicles. It uses an array
of servers to generate a duplicate of the original key, allowing the installation of a remote starter without having to give up a key.
The advantage is that this feature allows you to use one original key and the server to configure the bypass in the vehicle.
All Key2GO-compatible firmware are clearly indicated in the function list of each vehicle search result page and will also appear
on the flash page. Any first-time user must re-register to gain access to Key2GO, and some additional information will be required
to complete the registration process, such as your Directed account number and store name.
Key2GO is compatible with XKLoader2 and the online web tool, as well as XKLoader3 and the Directechs Mobile application.
Refer to “Module programming” of this guide for instructions on how to program features using Key2GO.

Connecting the module
Important!
Make all the required connections to the vehicle, as described in this guide, and double check to ensure everything is correct prior
to moving onto programming.
Note: Before connecting either the XL202 or SmartStart module to DB3, it is important to ensure that the proper feature and
function programming is selected using DirectLink (version 4.5 or higher). Visit www.directechs.com to download the latest version
of the application.
Warning! To take advantage of advanced features, you must use DirectLink 4.5 (and higher) or the Directechs Mobile application.
Flashing a module using your computer:
1. Connect the interface module to your computer using the XKLoader2.
2. Go to www.directechs.com using Internet Explorer, and select the Flash Module button.
3. Follow the instructions to select your vehicle, installation type, and configure your options.
4. Once you have configured the firmware options, click on the FLASH button.
Flashing a module using your smartphone or tablet:
1. Connect the interface module to your XKLoader3.
2. Launch the Directechs Mobile app on your smartphone or tablet.
3. Select FLASH YOUR MODULE and follow the on screen instructions.
When the flashing operation is successful, you can proceed with the instructions below.
SmartStart installation
The DB3 module must be disconnected from any power source before SmartStart can
be connected to it. Failing to do so could damage DB3.
1. To ensure that the D2D communication between SmartStart and DB3 works properly,
connect the Gray wire to a ground source (Rev B SmartStart), and cut the Brown or
Blue loop (Rev A SmartStart).
2. Do NOT connect the 2-pin harness (on SmartStart). Power and ground will be
provided by the DB3 D2D connector.
3. Connect SmartStart to DB3 using the D2D port.

Feature programming
To enter feature programming routine:
1. Turn the ignition ON, then OFF.
2. Within 5 seconds, press and hold the programming button until the LED turns ON orange (after 3 seconds).
3. Release the Programming button.
4. The LED will flash green once slowly to indicate the feature number is 1. After a short delay, the LED flashes red rapidly to
indicate the current option of feature 1 (e.g. 1 x green followed by 1 x red indicates feature 1 is set to option 1). The flashing
sequence will repeat until a new command is entered.
Changing feature options:
1. Press the lock/arm or unlock/disarm button on aftermarket transmitter to change the option of the selected feature. When
installing the DB3 in RSR using 3x OEM Lock Remote Start Activation only, there is no aftermarket transmitter on which to press
