So, you’re looking to enhance the convenience of your Ram 1500 by adding passive entry? You’ve come to the right place. Many Ram 1500 owners desire the ease of passive entry, and thankfully, it’s often achievable even if your truck didn’t come with it from the factory. This guide will walk you through the essentials, focusing on using AlfaOBD2 software to enable this feature on your Ram 1500.
Adding passive entry to your Ram 1500 typically involves a few key components and some software adjustments. The original forum post highlights a common challenge: figuring out the exact tools and software needed. Let’s break down what you’ll likely require, particularly when using AlfaOBD2.
Essential Tools and Software for AlfaOBD2 Ram 1500 Passive Entry
To successfully add passive entry to your Ram 1500 using AlfaOBD2, you’ll generally need the following:
-
AlfaOBD2 Software: This powerful diagnostic software is crucial for making the necessary configuration changes to your Ram 1500’s computer system. Unlike some generic OBD2 scanners, AlfaOBD2 provides the depth of access needed for modifications like enabling passive entry. It’s available for Windows PCs and Android devices.
-
Compatible OBD2 Adapter: You’ll need an OBD2 adapter to create a communication bridge between your device running AlfaOBD2 and your Ram 1500’s diagnostic port. The original post mentions the OBDLINK EX, which is a reliable wired option known for its compatibility with AlfaOBD2. For those preferring Bluetooth and potentially using an iPhone with JScan (as suggested in a comment), the Vgate vLinker MC+ Bluetooth OBD2 adapter is also recommended. Ensure the adapter you choose is fully compatible with AlfaOBD2 for Ram 1500 models to avoid communication issues.
-
Tablet or Smartphone: AlfaOBD2 can run on Windows tablets or Android devices. The user in the original post considered a budget Android tablet. While USB-A ports are common and convenient, many modern tablets use USB-C. As long as your chosen OBD2 adapter and tablet can connect (potentially with an adapter for USB types), it should function. Alternatively, if you’re in the Apple ecosystem and considering the JScan route, an iPhone or iPad paired with a compatible Bluetooth OBD2 adapter like the Vgate vLinker MC+ will work.
-
Security Module Bypass (12+8 Adapter): Newer Ram 1500 models (specifically from 2018 onwards, including the DT generation mentioned) often have a security gateway module that restricts access to vehicle systems. To overcome this when using AlfaOBD2 for programming, you’ll likely need a security module bypass cable, often referred to as a 12+8 adapter. The Kaodtech security module bypass and the generic “OBD2 Cable Adaptor for Chrysler 12+8” mentioned are examples of these bypass cables.
-
Passive Entry Kit (Optional): For the physical passive entry functionality, you might need to install door handles with sensors and potentially additional wiring. The NisMopar 2019-2022 Ram 1500 DT Add Passive Entry Front Doors Kit is mentioned as a comprehensive kit. However, as the comment suggests, sourcing parts individually, potentially using the linked forum thread as a guide, might be a more cost-effective DIY approach.

Steps to Enable Passive Entry with AlfaOBD2 (General Overview)
While detailed step-by-step instructions are best found in dedicated guides like the linked forum thread, here’s a general overview of the process when using AlfaOBD2:
- Physical Installation: Install the necessary hardware components, such as passive entry door handles and any required wiring, based on your chosen kit or DIY parts.
- Connect AlfaOBD2: Connect your OBD2 adapter to your Ram 1500’s OBD2 port, and establish a connection between your tablet/PC running AlfaOBD2 and the adapter. Ensure you use the security bypass if required for your model year.
- Vehicle Configuration Changes: Using AlfaOBD2, navigate to the appropriate modules (likely the Body Control Module – BCM) and locate the settings related to keyless entry or passive entry.
- Enable Passive Entry Feature: Modify the relevant settings within AlfaOBD2 to enable the passive entry functionality. This typically involves changing parameters from “disabled” or “not present” to “enabled” or “present.”
- Test Functionality: After making the software changes, thoroughly test the passive entry system to ensure it’s working as expected.
