keyless entry-no engine crank over
My 08, 2500 w/6.7, wife went to get truck washed and detailed, looks good but now it is sitting in their parking lot because it won't crank (engine won't turn over). Also the key fobs don't function either, tried both, no lock or unlock. The rest of the electrical works, lights, gauges, windows, etc, batteries charged. Jumped the selaniod at the starter and engines runs only when key is in the cranking position. Any ideas. Thanks in advance, Joe.

I'm hoping they didn't bugger something up when cleaning the engine. Your right it is the security system, it sounds non-operational. Hopefully they can reprogram the keys in without having to replace crap. Fingers are crossed for ya...

Just answered on another similar post as I've been having the same issue with my 07 4.7. I always disconnect the negative battery terminal and wait a moment or 2 before reconnecting to "re-boot". Starts right up every time. It has been an occasional annoyance since the first year with my truck. Perhaps I'll look at changing that thing you mentioned. Happened the other night and yesterday as well.

Happened again this afternoon. But instead of disconnecting the battery for a few moments I took out the IOD fuse for a few moments (as Traceis posted) and it fired right up. Now, I feel I finally know what the issue is and since I now know there is a recall I'll contact the dealer when I get a chance. Thanks!

Here is the TSB that is related to this issue. Perhaps it could help you or others on this thread.
NUMBER: 08-007-08 REV. A
GROUP: Electrical
DATE: July 04, 2008
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if
equipped, the replacement of the Electric Steering Column Lock (ELV). The WCM is also
referred to as the Sentry Key Remote Entry Module (SKREEM).
MODELS:
2007 - 2008 (DR/DH/D1/DC/DM) Ram Truck (1500/2500/3500/4500/5500)
2007 - 2008 (JK) Wrangler
2007 - 2008 (J1) Sebring (China)
2007 - 2008 (JS) Avenger/Sebring
2007 - 2008 (KA) Nitro
2008 (KK) Liberty/Cherokee
2007 - 2008 (MK) Compass/Patriot
2007 - 2008 (PM) Caliber
2006 - 2008 (PT) Chrysler PT Cruiser
NOTE: This bulletin applies to vehicles built on or before May 05, 2008 (MDH
0505XX).
SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the
remote keyless entry (RKE) system will not operate. This condition may be due to an
electrostatic discharge (ESD) from the ignition key into the Wireless Control Module
(WCM), causing the WCM to electronically lockup. This condition may occur more
frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is

more easily produced. This condition is corrected by the replacement of the WCM.
DIAGNOSIS:
1. With the condition present (i.e. the vehicle in the no crank / no start condition), connect
the StarSCAN® scan tool to the vehicle.
2. Turn the ignition switch to the “ON” position, and power up the StarSCAN®.
3. If the WCM is electronically locked up, the StarSCAN® will display the WCM as being
“off bus”.
4. If the no crank / no start condition is present, and the WCM is “off bus”, then reset the
WCM by temporarily removing the IOD fuse (with the key out of the ignition switch),
wait for 10 seconds and then reinstall the IOD fuse.
5. With the IOD fuse reset having been performed, verify that the vehicle will now crank,
start, and run.
6. If the condition is temporarily corrected by performing the above steps, and if the part
number of the WCM is earlier than the part number of the WCM listed in the part
reference table in the Service Bulletin Parts Required Section below, then perform the
Repair Procedure.
