Dodge Dakota skimm module (immobilizer)?

What is the reason you think the module failed? Error codes or what else. Does a scan tool talk to the current module? What codes is it showing? Have you tried re-flashing the current unit? The module itself is in the steering column. You remove the shrouds from the column and the module and antenna are right under the covers. About the only place to get a replacement will be through a dealership if you want to be able to program it to work in your vehicle, they are a write once part. So you enter the correct country code and options codes in the module or it will not operate properly if at all. You also must use the factory scan tool to program them as the aftermarket tools don't work on that module even though they claim they do.
