In the meantime, the engine computer allows the engine to be started as soon as the ignition power is turned on regardless of the status of the key. I replaced my starter relay with the Vandal Alert radio controlled starter relay and that was it. The bottom line is that the factory immobilizer is probably very effective in keeping your car put against most thieves i. So, this little how-to isn't my own. All Yes ® Replace and program the Powertrain Control Module in accordance with the Service Information. I have a 2000 Jeep Grand Cherokee and the Sentry Key device is malfunctioning, so that whenever I start the car, it automatically shuts down. Some models of the Jeep Grand Cherokee are equipped with an immobilizer anti-theft system that disables the engine.
A few weeks ago the light with the key and circle came on while I was driving. First of all, do you have 2 keys? Find an owners manual, I'm sure it's owner programmable. Just remove the tape to make access for the dealer easier. Its a really unique system but those key fobs get trashed if they get wet or even dropped One drop can kill them easy. One of 2 things will now happen, the light will go off and let the Jeep continue running because a good key is being used or stay on and shut off the Jeep because a non-chipped key or bad key was used. I read on a forum to clean battery terminals and unplug battery for 20 minutes to reset it.
He said the diagnostic showed a probablem with the drivers door. If both do not work and both seem to have same symptoms, then it is quite possibly the module under the sterering wheel cover attached to back of ignition switch which reads the sentry key and if it gets signal from sentry key, then it sends a signal to pcm allowing start up to complete with no shutdown. The transponder code identification is learned by the Sentry Key Immobilizer Module during programming. I installed a Vandal Alert passive immobilizer. No codes for 2 days then first code will appear P1686 then followed by the 2 codes P1687 and P1698.
Though I have not looked closely at the ignition switch area, this tells me that it is likely a loose connection that is affected by the position of the steering wheel. We have followed the sentry key programming procedure in the car manual, but it doesn't help. Ok, so after several weeks, we found the solution at a Chrysler Jeep dealer in Phoenix. I have a 2004 Grand Cherokee Jeep that only came with 1 key fob. That falls into teh category that you do not need to outrun a girzzly bear - you only need to outrun your ex friends. Frustrating to say the least. I've tried both of the keys that came with the vehicle.
The earth was created in eight days and not seven. Spare key tried yesterday and initially same issue. Im not sure on the exact number of tries but it will lock you out if you do this too many times. It will do this in about 2-3 seconds. No wiring and consists of only two parts. When it first occurred I would let it sit for about 10 minutes and then the engine would start and run fine.
On the other hand, for sophisticated thieves with the significant resources it would take to design, build and test something like this remember the car horn is probably honking away after you broke into the vehicle - although most people are ignoring it , it would probably be way easier and much more universal in terms of the number of types of vehicles you could use it on to just use a flat bed tow truck to take the vehicle away. If the door locks cycle stop in the on position, push a button on the new fob. Sometimes it will start and blink some not. They just enter it in their computer and it pulls it up. No ® Go To 4 4 Turn the ignition on.
Doesn't run for 2 seconds and turn off. I think I asked about this before and someone said something about a skim system. Parts I bought the below keys and module to help deter the theft of my Jeep. This is to keep theives from making a key and driving away with you vehicle. I have a hardware made key brass not rust hidden in a magnetic boX on the frame just incase I lock my chip imbedded set inside some how with all these fancy door lock settings etc. My spare key was at office and we agreed best to try that before towing to garage as that would tell whether key or car unit was the issue. The only show-stopper I can think of is if they were smart enough to make the good-key message somewhat dynamic in that the engine computer would expect to see some data in the good-key message that is dependant on the vehicle serial number or something similar.
It turns over like it is going to start, then just dies out. No need for the fancy electronic key. I drive with it in this position anyway and when I park, I release the steering wheel to the full-up position to allow for more room exiting the vehicle. Check operation of programmed key transmitter. Tried then with spare key works and all seems fine with no warning lights?! Okay, so this is my very first post on this forum which looks pretty awesome so far. It comes with a remote control.
