How to bypass a security system

Not gonna happen. Contact your Dodge dealer.

I got a 04 durango 5.7 car lot i got it from didn't have a key they started it by taking the ignition switch off now it lock out won't do anything lock smith came out to program a key his scanner says no ecm detected now what?

Go find a pcm on eBay that has the ignition switch and two keys and both key fobs install an your done. About 175/250 for the set. Be sure and disconnect the battery first then cycle the key on for 30 seconds then off to drain any stored voltage then install ignition switch and computer (pcm) and reconnect the battery , the new pcm and key fobs will work with out any future problems, re: battery goes dead it will be factory matched and no reprogramming will be required. If the pcm or ecm is not available to a programmer or scanner there could be other issues like a blown fuse , fuseable link ect... Make sure your not over looking the simple things. Security light is on then the pcm is working and has probably locked out any additional attempts to access the pass lock program feature and would require a dealership to reset or reprogram or a reconditioned replacement at a cost of around 1000.00 check with eBay seller if the one available will work with your vehicle. Things like 4x4, automatic transmission, engine ect must be the same. Good luck .

you said "Not gonna happen. Contact your Dodge dealer." what would the dealership be able to do??

I am still trying to fix my car, but not from "under the hood" but from behind this computer screen. So at this point, I have figure that the first thing that I need to do is to replace the wiring that was hotwired from behind the drivers door & the trunk. I am looking for a junkyard that has them. Than after getting them, I figure that I need to find a mobile automotive electrician mechanic/technician. Where I can find one?? I have no clue!! haven't yet.. any suggestions from anyone??? I would love to hear.

FINALLY, I BY MYSELF FIXED MY CAR!!! with the help of people answering my post. I first went to some junk yards & found the wires that had been "hot-wired/destroyed" and replaced them. After that, I referred back to all of the responses that I collected from people. I editing the info, making it into printable form & as a list, in the order of priority. The first was, "RECHECK THE WIRES THAT WERE WORKED ON BEFORE. HITTING THE BUMP MAY JARRED THEM LOOSE" "CHECK THE GROUND CONNECTIONS ON THE BATTERY & ANY OTHER GROUND POINTS ON THE CAR." "MAKE SURE ALL GROUND CONNECTIONS ARE CLEAN & TIGHT." So, after I did that, the car started! Took less than 15 minutes! It had been down since before Xmas. It took me a lot of time to methodically go through all the steps I thought that I needed to fix my car on my own, having limited funds. I want to thank you all for helping me.. without your help I would not have been able to fix it myself!! THANK YOU!!
