IdatalinkADS-ALCA Multi-Platform Immobilizer Bypass - Remote Start and Databus Interfuse (ADSALCA) - A bypass module is a piece of hardware that allows the remote starter to mimic your vehicle’s key.

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.

Car alarm starter, easy to install and great price. Good range perfect fit

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.

Do your research!I'm a DIYer, not scared. Not impossible. I know dc circuitry. If you have a clue, no problem then. If this is your first time cutting a wire in a vehicle, I wouldn't suggest proceeding with this.Will need a dongle to flash to your specific vehicle. So count on buying that too.Also idata document #77704 type 4 wiring, there is a flaw having the key sense and relayed key lock on the same circuit. The relay kick backs current into the circuit and confuses the status input of the bypass causing it not to start sometimes and setting off the factory alarm. The diodes in the diagram do nothing to help this being the current flow is in the wrong direction of the placed diode. Use r/s' status output for the diodes key sense and the r/s' rear defogger for the dioded and relayed key lock circuit.Took me awhile to figure out what was going on.Good luck!

I just want to comment on a review that I read concerning a customer saying that the unit would not talk to his vehicle Chrysler 300 seed his installer obviously didn't know what he was doing the units have to be programmed and make sure the wiring is correct two units do not give the same fault I stand by these units I've been using them for years at least 200 + probably had two bad units great item

One of the best and most convienent bypass modules to use. Simple to install, I sell this my bypass of choice to most of my customers. Not for the diyers, as a remote start should not be to begin with. If you dont know what is required to make this bypass work, its best to get it installed by someone who does. These bypasses way outlast some of the xpresskit modules such as countless pkall's, xk06's, etc that I have replaced with this. I just wish they had more firmware for rsr setups, but thats off topic.

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.

I was not able to use this product to install my compatible remote start/alarm system. The unit requires firmware version CH5 for my vehicle...the one I got had CH4 installed. Having anticipated this, I also had in hand the USB programmer cable. The firmware is only available on the idatalink website. They refused to give me access because I am not a licensed dealer/installer. The guy I talked to is a tech support rep for a company that will only give support to licensed installers--this makes no sense at all (licensed installers don't call tech support because they install this stuff for a living.)
