Question about Dodge 2007 Grand Caravan
Originally thought the battery was dead. Jumped it. Did not help. There is power to the dash and interior lights. The keylees entry is not working. I searched the internet and called the dealership. All the info on the net points to the Sentry Key Immobilizer Module. I was told there is a way to bypass it??? The dealership said it could be the SKIM or the WCM. Apparently I have to get a PIN code from the dealership in order to replace the module? I pulled the IOD fuse, sat in the vehicle, doors closed, turned the key to on off position to get a code. The only code was P0073 for the Ambient air temp sensor. And I replaced the battery in my kefob. That would not have anything to do with it right? So what I really want to know is if there is a way for me to bypass and save me money on a tow, shop fees, part costs (I'm told by the dealership it could be anywhere from $150 to $500)

What I find confusing is the designation 'IR' which is applicable to TV and stereo remotes but have never heard of it used for automotive locks.
It stands for 'Infra-Red' and this is only effective with 'line of sight' applications.
I know every one I've ever owned could be operated without the vehicle even visible as long as the range was not more than 50-70 feet.
These systems use radio frequency signals modulated by digitally coded signals to prevent 'one remote fits all.'
It would be interesting (as long as your patience doesn't wear thin) to find out how you have resolved this.
Mr. Massengill gave good advice since the battery contacts are now made so cheap that they won't donate a few microns of gold to them. Most I've seen were tinned at best.

you may very well be on the right track here... if it were me and my van here, i would replace the dimmer. i bet you can get another from a parts house without going to the dealer. then again... get the price from the parts house and see if the dealer will match the price for the part ( under the current big 3 situation they may do it)

2005 caravan's had software issue with power door lock operation..the body controller may need a software update..check with local dodge dealer to see if service bulletin applies to your vehicle..have seen body controller problems as well

Check with dealer on technical service bulletin, and/or recall regarding this. My Daughter had same problem, it was to do with sensor in ignition for recognizing key.
Have heard some say, reducing static before putting key in also helps, such as rubbing hand across metal roof or door post prior to inserting key. Dealer stated it's to do with radio frequencies interrupting signal, but they don't sound 100% sure on that either , but apparently new part is less, or not as sensitive.
