I know the beeping twice when opening the door is the fob battery going flat.
Today SWIMBO asked what it means when she hears two short beeps when she opens the door. It only happens occasionally, perhaps once a week or two, it has happened for a few months but she forgets about it.
I tried both fobs - ok, went walking down the road, both fobs worked fine when I must have been well over 100ft down the road, I was impressed at the distance they worked from, compared to my motor and bike. How the bloody hell can it think the batteries are going flat when they work from that distance.
My main question is how it can tell when the batteries have been changed. Is it the signal strength, because a new battery is not going to work from any further away. Or will a new battery mean I will have to take my phone to ask her if it is working.

It stops beeping !
 
I believe the fob sends a low battery warning in the data stream. So if the fob detects the battery is low, a signal to that effect is sent and the car responds by sounding the beeper 5 times on opening the door.

I thought the same thing. Because the fobs work from such a distance, I wondered if it was that, or had a built in calendar that sends a signal in the stream after a pre set time.
Ok there is just change the batteries, but saying the batteries are going flat when they work from half way down the street bugged me.

I'm of no help whatsoever but I know what you mean about bike alarms! The alarm on my Triumph Tiger won't arm/disarm unless you're stood less than 4 feet away yet will happily go off in the middle of the night....
 
I heard that it's easier for car thieves to clone the fob signal if it works from several meters away. Some manufacturers now only design them to work close up.

I bought a 1993 GL1500 GoldWing in 2012, coming back from Cornwall, the alarm started to go off at random while I was riding it, that was a fun ride home stuck in the inside lane.
