Buying a remote start or alarm system for your vehicle can be tricky because you have to make sure you the products you buy work with each other and your car.

This is a really common question: What Bypass Module do I need for my car?

A Bypass (aka Immobilizer Bypass) essentially interfaces with your vehicle’s computer, allowing the aftermarket remote start to start the engine without the key having to be in the car. A Bypass is required when installing a remote start in most new vehicles.

A Bypass can also be used to make installing aftermarket alarm systems much easier.

  1. Ok so you tell us all This but we still have no access to program that universal immobilizer module program to program it to our car we still can't do anything diy like you say in the video we have to own a authorized dealer to program everything. I understand 12v and I won't have a problem installing the physical modules but then what I have made my car useless because I can't program the immobilizer module to my car I have to pay a bunch to a audio shop to come down and program my "universal diy immobilizer module". somebody please get me the program so I can program the module to my car

  2. Does this mean the anti-theft system doesnt work after installation of this bypass. I'm thinking the vehicle can be hot-wired now… Is that correct?

  3. I have a 2007 Toyota Tundra and I've have the CA 5054 auto start alarm system. I lost my key and had to get a new one; when the key got programmed the auto start only whines the starter (seems as if it can't recognize the chip; can someone help)

  4. hi there, thank you for this great informative video.
    I have a question, as I need your help and advice.
    I have a Toyota fortuner 2014 (4L petrol engine) and I bought Viper remote start / security system 5607v. I need a bypass module to install the viper system to my car, but I couldn't find on your website anything about my car. could you please help me with that?
    thank you in advance for your help.

  5. I went to the sonic website and when I had to add the trim ,which is SXT and press go , nothing happened. So much for help from them. I went to the Fortin website and typed in my car stats and when it asked for trim type all that was available was standard key. What the heck is a standard key . Neither website was useful .

  6. The questions we need answered are do we need original key, more the one and if not can we use the bypass to start the car using a key that does not have the chip

  7. excuse me sonic electronics, you said that some of these modules can be used to unlock and lock doors, trunks so why some people install other brains with the bypass modules. together like audiovox, autopage, piton ,etc, it confuse me

  8. So if the key is left on the ignition (OFF position), there will be no need for the bypass anymore? Thank you.

  9. I have a 4 channel rockford fosgate amp and when i hooked it up to my speakers instead of music playing all i could hear is static, is my amp not working or did i do something wrong ?

  10. Question: Where do i start with building a double 12 inch enclosure for my car (sedan). (The trunk space is bigger then the actual openings.) I recently built a enclosure for my car. But by the time i finnished it and ready to fit it in. The enclosure was to big to either fit through the back of the car nor the backseat opening when the seats are folded down.

  11. what is the closest speakers to Bose quality wise for a 2000 Chevrolet Malibu LS? Because I am wanting a surround sound feel.

  12. I have Honda Civic 2013, Can I connect 5906V Viper with this FORTIN module for remote start & viper Security, as previously the technician I hired for installing 5906v Viper, He told me that It cant be installed for remote start, I'll have to put the key inside car :/
    Can I fix that issue now with this module ?

  13. i wish viper would just allow everyone access to their directechs site.

    it sucks as a previous installer that is out on his own to not have full access to that wiring database.

  14. what do you recommend for a 2006 Ford Expendition Eddie Bauer? Interested in buying a remote start security system, but I don't have a clue on what to look for?
