Just two days back from a 7 month deployment, running around base today in processing, went to leave one appointment to go to another and truck would not start. Tried a couple more times with no success. Pop the hood and check the batteries/terminals and they look good and are tight. Check the under hood fuses and they are good too. I then try it again and notice all the electrical options are working just fine. Then discover the key fob isn't working, it won't unlock/lock the doors. So I call the wife and have her bring her key, thinking the batteries in my fob are dead. Well her key does the same thing, no door lock action, and no cranking when the key is turned, but all electrical things are working, hear the pump, and clicking under the hood as normal. I thought maybe one of the batteries are going dead as they are the originals, pull them and have them load tested and they were good. So now I am thinking it may have something to do with the security system. Is there a security module of any kind and would it crap out like this?

 

Hey man welcome home. Hope you can get some rest and get worked back into your wife's house Thanks for the rotation


Actually, I think it just might be the batteries from sitting all deployment. I know you said they tested ok. But what does the voltage drop to when you crank? Might be too low.

 

Have you tried to jump start it?

The problem does sound like it is in the security part but weak batteries on these trucks do all kinds of goofy things. You might even just try a new battery in the key fob. Cheap and easy and will rule out one possible problem.

 

Thanks for the replies. Well I cleaned up the terminals and reinstalled the batteries and everything worked find! Go figure. I guess the computer got cleared out and it works fine now. I hope is doesn't become an issue though. After my trip to Omaha I will do an update on the 19.5 wheels and tires too.

 

a buddy of mine had that happen to his truck and all it took to fix it was pull out the fuse with the little white plastic clip around it under the hood. It is the keyless entry module or something to that nature. I assume pulling the battery cables did the same thing.

 

Glad to hear!! Now just keep an eye on the batteries

 

That happened to my wifes 2007 Dodge Caliber several years ago. Chrysler ended up replacing the keyless entry module. I ended up pulling battery cable to reset everything and later found out about the fuse. We noticed after they replaced the module the radio range was cut down to hardly anything. Before you could lock or unlock from inside the house. Now you have to almost be able to touch the car. Sometimes you can be 10 feet away but not always. We havent had that no start deal act up since the replacement. But for those with keyless entry this is always something to keep in the back of your mind that it could happen. I ended up keeping a cheapo crescent wrench in the car just in case I had to pull the battery cables.
