Car alarm failure on the 300C (how do you disable the alarm)
The alarm on my 06 300C failed on me yesterday disabling the car. The
alarm has gone of spontaneously a couple of times but it always recovered before. Yesterday it failed and I couldn't get it to reset so I had the car towed to the dealer. The details of the failure are as follows. The car wouldn't respond to the keyless entry commands. When I opened the door with the key the alarm went off. Putting the key in the ignition wouldn't stop it and the car wouldn't start. To add insult to injury I couldn't get to the battery to disconnect it because the battery is in the trunk and the alarm system disabled the truck button on the dash and the keyless entry buttons weren't working (I tried both of my key rings so I don't think it's a problem with the batteries in the key rings). This was the most embarrassing kind of failure, I was in the parking lot of an Audubon society bird sanctuary and they were having a lecture. You can imagine how popular I was. There must be a battery cable that comes from the trunk to engine compartment, is there a place where this cable can be easily disconnected? Is there any sort of system reset button in the car? |

Frankly I doubt that they've fixed the problem, if this were a software problem it would be happening to lot's of people. It feels like an electrical or hardware problem to me. Has anyone heard of an alarm lock up problem to the 300C? Does anyone know if it's possible to have the alarm disabled or devoiced? |

Take it to the dealer and have them scan the module, it will show up on the scan tool what the last reason why the alarm was triggered. Glenn Beasley Chrysler Tech |

Sounds like a Microsoft style repair.

I suspect that it's really a hardware problem, probably undershoot on a sensor line or perhaps a power supply glitch. If it were purely a software problem then it would be much more common then it apparently is. However it could be an exception handling bug in the software, i.e some sensor or combination of sensors is giving a reading that the software doesn't handle correctly which causes the computer to crash. |

Did anyone think of using the key to unlock the trunk from the outside? Or does the Tonka-300 not have a key-lock mechanism for the trunk? > 2) The circuit breaker box is easily accessible, just lift > up the carpet and its right there.

There is no key lock on the 300's trunk, the only way to open the trunk is with the keyless remote, the trunk button on the dash (which is electronic, it's not connected to a cable), or with the kidnap release which is there so mafia snitches can get out of the trunk before Tony has a chance to pop them. |

The rental Impala I had as a rental not too long ago had NO trunk key slot, and NO passenger door key. Totally dependent on the little key fob to get in the trunk. Pretty soon they'll eliminate the driver's door key slot. GM and Toyota have also eliminated transmission dipsticks on many models. Yee-ha. |

I'd locate the alarm horn wiring and insert a simple switch in the circuit for future use. > There is no key lock on the 300's trunk, the only way to open the trunk is > with the keyless remote, the trunk button on the dash (which is > electronic, it's not connected to a cable), or with the kidnap release > which is there so mafia snitches can get out of the trunk before Tony has > a chance to pop them. The lack of a key lock on the trunk was one of the many reasons I passed on the 300.. This is unacceptable design which I know comes from Europe, where I've seen it there on rental cars for some time. I once rented a Renault which had NO key locks anywhere. I assume there was some way to get in if the battery failed, but typical of rental cars the owners manual wasn't to be seen. |
