Are you sure you have and alarm. E46 did not come with a pre installed alarm. It was a dealer installed item. You can checked by removing the trim cover on the inside roof trim just behind the opening for the sunroof. Just pry if off with something thin like a credit card or something. If theres a sensor in there then you most likely have an alarm, if not then you don't. The most common problem would be the alarm siren that is accessed from under the hood. Search for E46 alarm install to see how to get to that.
If your alarm is sounding (horn honking/lights flashing) press the panic button on your key fob to shut it off. Otherwise, the alarm is disarmed when you unlock your door(s) by using your key, keypad on the driver's door, or the unlock button on your key fob.
Short circuit in your vehicle alarm system. In most alarms, some lights will flash on and off as an indicator of an attempted break in.
I just had this happen to my 2004 Grand Cherokee Limited. I turned out to need to replace the wire from the driver door into the car. Additional Info: This is a common problem for jeeps. As the driver's door is the most frequently used, the wires in the door harness have a tendency to kink or break. The same thing happened to my 95 GC Laredo.
There are many possible causes. With my sons LXi this problem seems to have been related to the factory security system and a faulty tamper detection switch at the trunk key-lock. Another symptom is the alarm (horn and lights) would sound off on its own randomly. You can tell if you have this problem by locking the car with the key or fob and watching the red light in the center of the dashboard under the rear view mirror up near the windshield. If the light comes on solid for a few seconds before it begins flashing, then your trunk switch has a fault. After the alarm sounds, it prevents the car from being started and leads to all sorts of autoshutdown (ASD) issues where the relays under the hood keep clicking until the fuses are pulled to reset the ASD and PCM circuits. Sometimes the engine may start, run for a few seconds and die. Locking and unlocking the car and trunk until the normal security light sequence (16 seconds of fast flash, then slow flashes) seems to put everything back in order. Or your battery could just be be extremely low. it takes much more energy from the battery to start a vehicle than it does to power the radio or interior lights. the clicking sound comes from the starter relay trying and failing to engage the starter and turn the engine over.
I'm making an assumption on the year probably a 90 something. I usually means that the security was on and the vehicle alarm was tripped. This is to let you know the alarm was set off and reset itself while unattended.
Insert the door key into the driver's door and turn.
The flashing lights are probably the factory alarm.
Horn is sounding, lights are flashing, and won't start. 1998 ford f150
Alarm system is armed.
The alarm can cause your lights to flash and keep the engine from starting. Remove the car alarm fuse, for 30 seconds. Put the fuse back into its original slot and the car alarm system should be reset.
Your alarm system is to blame for this issue, try disconnecting your alarm from the fuse box and try starting the car again.
cut all electric resources from the car.
I have exactly the same problem. been to the garage today and been told to use the re- programming sequence on your key. just cant find the sequence now! ha.
Usually inside the car somewhere on the dashboard or the doors there will be a red flashing light to indicate that the car alarm is working properly. The light is also there to warn off burglars.
If the horn is honking and the lights are flashing just push the panic button on the remote to stop it
