What extras if any will i need to install a remote starter on my 2004 dodge ram 1500 QC 4x4 5.7L With a black key


Asked by Jun 25, 2015 at 07:23 AM about the 2004 Dodge Ram 1500 SLT Quad Cab LB 4WD

Question type: Car Customization

I have a 2004 dodge Ram 1500 4x4 QC 5.7 L V8. It has the 7 speaker infinity sound system with the factory amp behind the glove box. 20 in stock chrome wheels, (I'm naming every single thing possible because this is my last resort so I want whoever may have an answer for me to know all the facts) it has a black key (not grey) its black with the ram logo on it and is exactly 1/4 in thick. The fob is separate, and is an oblongish shape with 3 buttons. Lock/arm, Unlock/disarm (press it twice consecutively and it unlocks all doors, and on the bottom it has a red panic button. Hmm, power driver seat, power mirrors, the thing on my celling that tells me temp, direct, MPG, Etc.. It also came stock with 4 wheels and tires and 2 windshield washer blades. Ha! Ok sooo lets start with, does anybody else have this very same truck? And if so, have you installed your own remote start? I can not get mine to work and I'm sure it's something stupid and easy. I'm no dummy when it comes to repairs and/or upgrades, especially anything electrical. In fact I would consider myself one step below professional just due to the fact that it's not how I make a living. Also, the brand I'm installing is a Ready Remote Model23927. I know there is some talk about needing a bypass that hooks up to my ignition but from what I have gathered is that I DO NOT need one due to the fact that I have a black key and NOT a GREY key?? And I have also heard some talk about some sort of factory alarm bypass?? Possibly a module of some sort..? IDK. I guess my main question all summed up would be-Do I need any extra anything (bypass modules, Etc..) or maybe some extra knowledge that's not given in the normal installation instructions or any information at all would be amazing!!! Thanks guys!

From researching this specific model, heres what I come up with. Below in an excerpt from the instruction manual. It does discuss a bypass module. The part number is listed at the end. ►►3) Factory Anti-Theft Systems Many vehicles come with an anti-theft system that must be temporarily bypassed for the vehicle to be remotely started. Some systems use a resistor in the key. Others use a transponder - a small device in the key that communicates a high security code to the vehicle before the vehicle will successfully start. Check the list of vehicles and the types of security systems on the following page. If your vehicle is listed, your vehicle has an AntiTheft System that the remote starter MUST temporarily bypass in order to start the vehicle. More information about the factory antitheft systems and vehicle wire colors can be found at the DesignTech web page www.designtech-intl.com. The Universal Alarm Bypass Module, sold under part #20402 or #29402 will temporarily bypass a factory anti-theft system when using the remote starter. Vehicle-specific anti-theft bypass modules and door lock modules are also available. Check with your local retailer/ installer to purchase the Universal Alarm Bypass Module or vehiclespecific anti-theft or door lock modules.◄◄ ►►ADDITIONAL INFO◄◄ The BROWN/WHITE wire is Alarm Disable, which will give out a quick negative pulse just before starting the vehicle. This wire can be used to turn off the factory alarm system in vehicles which have them. In most vehicles, this wire is located in the driver’s kick panel. A relay is needed for vehicles which require a positive pulse. 16. White/Black Wire - Ignition #3 / VATS - Control Harness The WHITE/BLACK wire, is a ground output that acts just like the Ignition 1 or Ignition 2 relay outputs (active in the “run” and “crank” positions). This wire is a 400 mA negative transistor output and MUST be set up to power a relay (not included). It can be used to power the third ignition wire at the key (necessary for most Ford vehicles). This is the wire that can also be used to bypass a passive anti-theft system by hooking it up to the Universal Alarm Bypass Module. See the Factory Anti-Theft System Section at the end of the instructions. Many meters have a known issue with measuring passlock. This is not a fault of the meter, the installer, or the manufacturer. These issues can cause problems such as getting a consistent reading of the resistance, or the reading may be artificially inflated. It is our belief that the mid- to-high-end meters seem to experience more problems measuring passlock than less expensive digital meters. One wire will have 0 volts - This is the wire you "tap" into-- we’ll call this WIRE #1 USUALLY BLACK OR ORANGE/BLACK. One wire will have 5 volts or less- This is the wire you cut in half-- we'll call this WIRE #2 USUALLY YELLOW. One wire will have aproximately 12 volts - This is the wire you leave alone USUALLY WHITE OR BLACK/WHITE. With all PASSLOCK wires intact, turn the vehicle on and bump the starter. Measure the voltage between the wire #1 and wire#2. Your meter should be set on the 12 volt DC scale. RECORD THIS VOLTAGE. Without turning the key off - go ahead and separate WIRE #2. Reconnect the Universal Alarm Bypass Module (Part #20402 or 29402) as described in the installation manual with one exception - GROUND the wire that goes to the ignition 3 wire; you should hear the bypass module click. Now measure the voltage between the ENGINE side of WIRE #2 and wire #1. Your meter should be set on the 12 volt DC scale. Adjust the dip- switches and trim-pot on the bypass module until the voltage being measured EXACTLY matches the recorded voltage obtained without the module. Remove ground from the ignition 3 wire of the bypass module, turn the vehicle off and then restart it. Look at the voltage again - and while monitoring it ground the ignition 3 wire of the bypass again. If the module is set correctly the voltage should NOT change. Repeat again to verify - if you get the same voltage every time then the module is set up perfectly. There is no chart to help you with this, it is just trial and error -- but it will work regardless of the meter you are using. Universal Alarm Bypass Module (Part #20402 or 29402)
