Asked by Apr 06, 2010 at 07:58 PM about the 2007 Dodge Ram 1500 SLT Quad Cab 4WD

Question type: Maintenance & Repair

Drove to work this morning, when I went to the truck to go home, remote unlocked doors, inserted key and nothing, all instruments lights came one, radio, headlights, but it would not turn over starter, checked fuses tied to ignition, tried jump starting, nothing!  No click. Checked connections to starter, thery were tight. One strange thing, remote will no longer unlock doors, put a new battery in remote, still won't work, got spare key, still no start or unlock/lock doors.

doesnt sound like a battery problem. so it is more than likely your starter. if there is enough room under the truck try tapping it with a hammer then try starting it again. had to do that to a ford out here in the desert. if it starts up look into a new starter

What I found out, accidently and after hours trying to get it started. I put a new battery in key, then disconnected positive battery post for 10 minutes, hooked the battery back up, and the doors unlocked and it started. Go figure, my told me about disconnecting the battery, and I rubber gloved high voltage all day with the key in my pocket, I wonder if the high voltage scrambled the chip in the key, new battery and reboot so to speak! Any one got any explinations???

Same thing happened to us. We disconnected the battery cables and touched them together. Then re-connected to battery. Used our second key and it started right up after trouble shooting for hours.

I have had the same problem. Disconnecting and reconnecting the battery always resets it and makes it work. This last time my wife had my truck as i was out of town and she had no clue so she had it taken to the dealer in town. They ran a diagnostic and found that the transmitter/receiver that is part of the security system for the trucks has a problem, and when it doesnt receive the signal properly from the key it activates the security system and will not alow the truck to start. That is also why your keys won't unlock the doors or do anything else. Bad part is they want $675 to replace the receiver and keys I guess. Think I'll just keep disconnecting the battery when it happens.

Disconnecting the battery is the way to go. Keep a 1/2 inch wrench and a large screwdriver in the vehicle at all times.

You can also disconnect the IOD fuse in the engine compartment fuse box for a few minutes then plug it back in. It is #11 and kind of a milky yellow fuse. The mechanic told me that the WIN module might need to be changed if it happens often. Not sure what a WIN module is or the cost.

Wow, Glad to see that I am not the only one with this issue. I found out that there is a static charge that build up on the key and when the key was placed in the ignition, it discharged. This confused the transponder in the key and the truck thinks that someone is trying to start it with the wrong key. ..... Disconnected the negative terminal for 30 seconds and it started right up.... Not even Dodge knows why this happens.

my truck 2007 with 96k on it has now done this to me 4 times now. 1st time while waiting for tow truck to take me to the dealr. ( could not open the door due to after market handle covers) on truck when bought. Searched on my phone while waiting found a solution after doors were opened took both cables off and touched them together. all good. second time 20k miles later same thing but doors were open. Same method and third time also. 4th time no luck held both lock and unlock about 40 secs then it worked. Went to the dealer to get a oil change asked about recalls one for airbag. and two out of warrenty items one was a tipm and a flash update 20 dollars each asked if it would help. told them my problem and another guy behind the counter said not sure but he new something that might help. he took fob apart rolled back the rubber shell around the circuit board side and then lift the circuit board out and used the small screw driver and gently scraped off the little dots on the rubber type piece not the circuit board because they get build up on them after awhile my two cents.
