Alarm Bypass Module Products

Having some trouble synchronizing your remote starter's operation with your alarm system? Your automobile's remote starter, also called a remote keyless ignition system (RKI), allows you to start your engine without using a traditional mechanical key. Your alarm system is an electronic tool installed in your vehicle in order to put off thieves from stealing your car and your belongings inside it. The alarm goes off when the circumstances necessary for triggering it occur. It emits a high-volume signal, normally a siren, klaxon, pre-recorded verbal warning, your automobile's own horn, or a combination of all those sounds together with flashing lights to inform you and the people around your car of a break in. Your alarm system may also have an optional feature that notifies you through a paging system and interrupts several electrical circuits needed for your vehicle to start. With both your remote starter and alarm system having been made through great technological advancement and variety, coordinating these two systems can get a little tricky. With an alarm bypass module you can go through the strictest alarm system while allowing you to start your automobile without spoiling the effectiveness of either assembly. This module enables you to bypass nearly any kind of factory passive anti-theft system available these days so that you can remotely start your vehicle without permanently disabling your car's alarm system.

Prevent False Alarms with the Right Alarm Bypass Module

The problem with a car alarm is that it can make too many false alarms that you no longer know when to check or ignore them. But who's to blame? Either you set your alarm settings too high or installed an aftermarket product improperly. What you can do, instead of reversing the settings of your anti-theft device and risking your vehicle security, is install an alarm bypass module that can temporarily disable your alarm while you remotely start your vehicle. But how do you know which is the right bypass module for your automobile? The answer is in your vehicle make.

What's in your make's ignition key?

  1. Acura, Audi, BNW, Chrysler, Dodge, Ford, Honda, Jeep, Lexus, Lincoln, Mercedes, Mercury, Nissan, Porsche, Saab, Toyota, Volkswagen, and Volvo use a transponder anti-theft system (TATS)-a transmitting device that sends a security code to the vehicle-in the ignition key's head. This system requires a universal anti-theft bypass module that will allow placement of the spare transponder key in it prior to installation in the transponder's receiver ring, which is around the ignition lock switch.
  2. Buick uses a vehicle anti-theft system (VATS). This system employs a resistor pellet in the key that sends signal to the vehicle once the programmed key is inserted into the ignition switch. VATS requires a bypass module with a variable or adjustable resistor, so it can match the dial-in resistance resistor value used in the alarm's settings. Find one from world-class brands like Valiant and Bulldog.
  3. Cadillac used VATS in its'98 and older models, except for Monte Carlo '99. All other Cadillac models produced since ?99 to this day are equipped with either a transponder or a passlock II alarm system. If your model has a VATS in it, opt for a bypass module with an adjustable resistor. But if you have a TATS or passlock II, get a bypass module that will allow placement of one of your programmed transponder keys in it.
  4. Chevy, Oldsmobile, and Pontiac use VATS, passlocks I and II, and transponder alarm systems. Basically, '99 production models and older are equipped with VATS. But there are also some Chevy models using passlock I as early as ?96. You can easily identify what's in your ignition, and thus what your alarm system needs, by checking your model's manual. Passlocks I and II are pretty much the same to VATS in construction. They all require a bypass module with dial-in resistance resistor. If your vehicle model belongs to this category, get a bypass module with an adjustable or variable resistor with 10-turn Potentiometer.
  5. Isuzu and Saturn use Passlock II alarm system. If your car make belongs to this class, you'll need one of those universal 10-turn Potentiometer or variable/adjustable resistor.

DIY Installation of an Alarm Bypass Module

The anti-theft device attached to your ignition switch will keep anybody without the proper key/s away from your vehicle. But it can also become inconvenient because you can't start your vehicle using a remote starter. That's when you need an alarm bypass module-the perfect add-on device for your factory vehicle anti-theft device (VATS), passlock, or transponder alarm system. This module has an antenna that will go around the receiver ring on your ignition switch and take commands from your remote starter. How will you install it in your ignition switch? Use these simple step-by-step instructions we have here:

Difficulty level: Moderate

Things you'll need:

  • Universal (VATS/passlock/transponder) alarm bypass module
  • 8-pin wire harness
  • Cable ties
  • Ohm meter
  • Electrical tape

IMPORTANT: Identify the type of alarm in your vehicle first before proceeding with the installation of your bypass module.


Step 1: Get its resistance rating, which should be between 392 and 11,800 ohms, using the ohm meter. The module has 8 dip switches; turn switches 2-6 to the dealer's recommended values, while switches 1 and 7 are turned to "off" position. Place the ohm meter probes to the two silver resistance measuring pads of the module and dial-in the matching resistance values.

Step 2: Tap the VATS wires and connect the bypass module.

For passlocks:

Step 1: Remove the lower steering column cover and locate three 20-gauge wires coming from the key cylinder, and strip the black and yellow wires. Cut yellow into two.

Step 2: Shift to reverse, turn the key to "start", and then release to "run" position. Measure the resistance between the key-side yellow and black wires. Use this resistance values to set the bypass module.

Step 3: Locate the black bulb test wire in the main ignition switch harness, and connect the bypass module to it. Use electrical tape to close all exposed connections.
