Hello to all, and thank you in advance for taking the time to read and hopefully answer my question. I am in the process of shaving my door handles. It is a 2007 Dodge Magnum SXT. My rear doors are on a push bottom under my dash and will not be affected by any solution to my problem. They are totally seperate and should not be considered. I also have disconnected the lock and the locking mechanism on all doors. The only moving part in the door will be the solenoid. What I would like to do is use the factory keyless entry instead of having a seperate keypad on my keychain. The factory key has a lock, unlock and panic button. I have found that this system uses a single wire lock set-up. The unlock fires at 342 ohms and the lock fires at 100 ohms. I would like to hit the "unlock" button, it would fire a ground to a relay which would fire the solenoid in the driver side door only. I could then hit the "lock" button and it would do the same but in the passenger door only. How can I use the 342 ohm and 100 ohm differences to "seperate" the two doors and fire the relays only for the correct door. I have a feeling that this can be done with a resistor or two but I am not to knowledgeable in resistors and this field. Any help would be great.

If it is possible to isolate the ouputs from the keyless entry module, how will you lock the doors?

There is no need to lock the doors when the handles are shaved. It's pointless to do. There is no handle to grab. Therefore, no reason to lock something that is not there.

If your asking for the remote's "unlock button" to control both locking/unlocking of the driver's door and the remote's "lock button" to control both locking/unlocking of the passengers door, then you will need to know how the keyless entry module intregrates into the vehicle, via wiring direct to the relays or through the ECM. Either way, you will need a flip-flop circuit to accomplish this task and you will probably have to build a completely new lock/unlock relay circuit.

Is there a factory alarm to contend with?

I only need a single shot of 12v+ to open the door. There is nothing else required to close it. The solenoid is on a spring return. I need a 12v+ to one door and a 12v+ to the other door. The factory keyless gives off a ground so I know I will have to use a relay to reverse polarity. I understand that. What I need to know is how to filter the 342ohm and 100ohm signals. If I were to do it without it then both doors would open when I hit the "lock" button and they would both open when I hit the "unlock button" If I can seperate the 342ohm and 100ohm signals then I could use the 342ohm (unlock button) to pop the soleniod on the driver door and the 100ohm (lock button) to pop the soleniod on the other door. It took me a minute to understand the concept of not having locks when I first started researching this also...lol

I do not belive so.

Locate the PURPLE / green wire in connector 3, pin 21 at the body control module. When ground is applied to this wire through a 5.3 K ohm resistor the doors will lock. When ground is applied to this wire through a 2 K ohm resistor the doors will unlock.  I think I would need something along these lines...... any ideas?

Some shaved installs use a solenoid without spring return to deabolt the doors. That was my confusion. I'll try to help as best I can. Hopefully someone else with better knowledge of this vehicle will chime in. You don't need to worry about the resistor circuit you mentioned in your opening post. That is for integrating into the vehicles factory lock/unlock signal wire. Using the factory lock/unlock motor wires to drive your solenoids, you will isolate the lock/unlock power for each solenoid with a simple diode and relay. Give me some time to locate the relay diagram for your vehicle and I'll give you the factory wire colors and the circuit needed? Will that be ok?

Ok short and sweet. Use a single factory motor lock/unlock wire in each door that shows 12v for the function you want for that door. I don't have the actual color for each door. However, since there are only 2 motor lock/unlock wires in each door, it's a simple method of using a DMM to identify. Make sure you properly insulate the unused wire. Use that wire to drive a fused, relay circuit for the solenoid.

Let me know how it works out for you.

Thanks again, I have run into a little issue today. I was able to isolate the wires and use the lock and unlock buttons for the solenoids like I wanted. The driver pops when I hit unlock and the passenger pops when I hit lock. It works great, well did untill I remebered something. After driving and reaching 5mph the doors automaticly lock. Which in turn pops open my passenger door. Any idea on how to locate this safety feature and disable it?

man thats crazy i own a magnum and forgot about that. that is too funny did it get damaged or anything while you were driving. a dealer has to shut that feature off or there is a small possibilty you can change it your self,. if so the manual will tell you exactly what to do.

Naw I rembered before hand so I tested it in my driveway in a very safe way. So any ideas on how to disable it?

Or even how to change it so the unlock button once will only unlock drivers and then unlock again will unlock the rest of the door. There is a setting for this in the EVIC system but my model did not come with that.

use the second unlock wire from ur alarm assuming u have one, to drive the relay that is currently activated by ur lock wire. sorry just re read, realized ur tlkin about a factory alarm.

You could wire up a relay to interrupt the lock wire in the passenger door and have it triggered by ignition. Basically just wire it up like a starter kill relay. So the door cannot pop open once you start the car. But then there ONE drawback, since you cannot pop the door open while the ign is on, a passenger may feel trapped if you go to let him out with the engine still running. Unless...you wire that door to a dash button like the rear doors. This button could trigger the relay just like the remote triggers the relay. But you would only want to interrupt the lock wire and not the wire from the button. So then you could pop the door by remote when the ign is off, but when the car is running, you will have to press a button on the dash(or wherever you mount it). Thats the easiest way I could think of to bypass the 5mph locking, anyone else have any ideas???

It should be possible to reprogram the RPM door lock function off. Otherwise, for something custom, I would need the service manual.
