Although I'm a member of other RAM forums, this one was recommended to me for the first time today.

We have a 2012 Dodge RAM 2500 CTD 4x4 that has an intermittent Wireless Ignition Module (WIM). It appears that they can be purchased - with key fobs - from various sources, but my question is whether or not there's more to it than simply replacing the WIM? In other words, do the keys fobs have to be "programmed" to the truck's electrical system before they will function properly?

In case this issue is new to anyone here, the WIM is the box/module behind the dash work that accepts the ignition key fob to start the engine. At the moment, our WIM will start the engine just fine, but, if you bump the key fob (even slightly), the engine will shut down. Needless to say, this is an emergency that's just waiting to happen.

Thank you kindly for your time
