Alarm system intermittent response - 2 different keys

Recommended Posts

Hi, i have a 03 Box S and I just started to notice that when I arm my car sometimes it will not "disarm" using either remote key --- it flashes red on my key, but no response from the car. In front, on the side, anywhere --- nothing. All I am left with doing is unlocking the door using the key and then placing the key in the ignition just as quickly as possible. Of course this turns the now "blaring" alarm off, but I wonder what could be causing the alarm to stop responding to my disalarm signals from either keyfob remote. (this happens if I try to disarm using either of my 2 factory original keys)

Also, none of the other keys work either, like the "front or rear trunk" which will usually unlock and disarm the car likewise. It is like it is just "locked up"

Then after resetting the car with the key in the ignition, it works fine --- alarm, arm --- perfect.

Any ideas or suggestions?

Does it happen immediately, or after the car has been sitting for a few days? From my understanding, the remote doesn't work if the car sits for so many days - by design.

It happens when the car has been sitting definitely more often (if not everytime) than it does when driven regularly....Is that part of the car just getting upset at you not driving it? :lol:

Funny thing is that it is still flashing the alarm LED so doesn't look like it goes into complete hibernation mode or anything.

Is this by design to reduce battery drain or security?

From the Owners Manual:

"The remote-control standby function switches off after 5 days If the vehicle is not started or unlocked with the remote control within five days, the remote control standby function is switched off (to prevent discharging of the vehicle battery).

1. In this case, unlock the driver's door with the key at the door lock. Leave the door closed in order to prevent the alarm system from being triggered.

2. Press button 1 on the remote control.

The remote control is now activated again."
