Review: Do your research and this is a great product that works as advertised! - Product was easy to install and worked exactly as described, software was easy to download, as were the wiring instructions and installation directions. If you are a first time installer, do your home work, there are many resources out there with helpful tips and warnings to save you from making costly mistakes. I spent 6-8 hours of research before I started removing any of the access panels on my wife's SUV. Put together a binder with step by step instructions, highlight those steps that apply to your application, and make notes. I had a binder with over 55 pages of illustrations and notes, includiong a step by step I put together for my application. These are just suggestions, I am not claiming to be an expert by any means, but they were helpful to me, and installing this databus bypass transponder in conjunction with the Compustar CS800-S, I did not have one issue and everyting worked correctly the first time with all safety features and functions working as designed. I only needed one key to program the Idatalink using the KLON installation. Both the 12volt.com and Commando car alarms-vehicle wiring search websites offer free diagrams and step by step, wire to wire connections for most automobile applicatons. I am tankful that these websites take the time to offer to help the DIY'ers. As you will no doubt see numerous times with this databus bypass by IDatalink, do not forget, you will need to purchase the IDatalink Weblink Updater harness that will connect the module to your PC via USB port to download the particular software applicaiton you will need.
Review: Worked great on my 2006 Saturn Vue and with the Compustar CS800-S remote start system - Worked great on my 2006 Saturn Vue. I used this idatalink ALCA databus with a Compustar CS800-S remote start system and it works with no problem. All the connections to my ignition switch were fairly easy to get to and I soldered them all and double taped them too. Took me about 4 hours to install it because I triple checked every connection via the paper instructions and on the internet at their websites. I took my time because I did not want to short anything out. If I did it again It would be half the time.

## Features

- A bypass module is a piece of hardware that allows the remote starter to mimic your vehicle’s key. This iDatalink ADS-ALCA data bypass module communicates operating commands from a compatible remote start/security system controller to your vehicle's onboard computer system to enable direct control over your vehicle's functionality.
- When immobilizers were introduced, aftermarket remote starters had to be installed alongside one of your expensive vehicle keys, or the factory security features had to be disabled entirely. Then came the bypass module to bring back the magic of keyless entry and remote start.
- DATA BYPASS MODULE: Communicates operating commands from a compatible controller to a vehicle's onboard computer system for seamless communication, without having to modify sensitive components. Compatible with select remote start/security system controllers. With a hardwire connection option that allows functionality with most controller brands for wide-ranging use.
- VEHICLE-SPECIFIC FIRMWARE (download required): Supports more than 35 vehicle makes and 4000 models, so you can easily customize your data-to-data connection for your particular vehicle type. Plastic and copper materials. With a protective coating ensure a durable design.
- WHAT'S INCLUDED: iDatalink Data Bypass Module for Most Remote Start/Security System Controllers, Wiring harness, Owner's manual
- Download "Weblink" Desktop Software (No-Charge) on Idatalink website. Click on "Weblink" located under the "Support" menu tab. Idatalink ADS-USB is required for this and sold separately. ** Professional installation is highly recommended.

### ⭐⭐⭐⭐⭐ The only bypass you should look at.
*by M***T on November 12, 2014*

Good module. This works in practically every car on the market. It is a data bypass so it needs a key to initially program it but not one to keep inside it. Buy it here on Amazon as other places will charge you $90 for it. FYI, You need this to bypass the immobilizer in modern cars that use transponder chips in the keys or fobs to start the car. This will replicate the transponder encryption so that you can install a remote starter or whatever in your car.
