2005 Grand Cherokee WILL NOT START! Security System

Hello,

I have a 2005 grand Cherokee with a stock alarm system that will not start. Battery fully charged, lights and radio work. I can arm/ and disarm alarm with keyfob.

When I turn the key to start the car the starter doe NOT crank at all. It seems to be as if the security disabler is active.

this happened to me once before and after having the vehicle towed I left the battery disconnected and the car started the following morning.

Once again this happened today, so I have left the battery disconnected and hope it will start in the morning.

I would like to disable the stock alarm system . Anyone that has any info please help.

Thanks

The security system doesn't stop the starter from cranking, it stops the fuel pump from running once the vehicle's started.

Your problem is more likely with the starter motor or the ignition switch itself.

If you're thin and flexible, you can shimmy under the front end and wang on the starter motor with a hammer while someone tries to start the Jeep. If that works, you need a new starter.

Does anything at all happen when you turn the key to the start position? If the switch is good, the interior and should go out, all the dash lights should come back on for a check, the usual.

If the starter does nothing, then it is likely a problem in the starter (or switches). The security system does not prevent the starter motor from working. From the owners manual:

The system will shut the engine off in two (2) seconds if someone uses an invalid Fob to start the engine.

Colin,

When the key is turned to either the on or start poistion the dash lights turn on and the dashboard goes through all of its normal functions.

From what you stated earlier it sounds like its the starter. I will try to banging on the starter tom.and try and start it. I did notice that last time this happened it was also very cold. i live in NYC

thanks

I had this problem when I first got the car, same symptoms that you post. I initially thought it was a security problem. My dad (mechanic for 35 years) got under the car, told me to start it. The connection to the starter was loose. We had to bring it to his shop, put it on the lift and tighten some bolts, check some wires and it hasn't had a problem since.

alvar309,
Did you ever get this resolved? My wife's 2010 is doing the EXACT same thing you're describing under the EXACT same conditions (cold temp - 27 degrees). If so, what fixed it? It seems like Devilsmed98 had a solution but I wanted to compare his resolution with yours.

Any help would be appreciated.... Jeep is sitting dead in the street and we have a storm coming. Would like to get the thing out of the street and in the driveway for now and ultimately get it fixed. This is the second this happened.

Thanks,
Charlie
