Can't believe I didn't think of this. it started happening when the key was falling apart, and I was taking it to the beach every day. The key guy replaced the shell a couple of months ago but it kept happening. I'm taking it to him today, I'll let you know how I go.

Hit the red button and hold for a couple of secs and you will get a horn beeping (good for finding lost car in carparks)
Press again and it should go into alarm mode.
I always thought that if you held in the panic button (red), it just went straight into alarm mode?

My car is doing the same thing.. Was it the key that was the problem? Or what was the issue! I have no idea where to even look

I’ve got the same problem, the alarm keeps going off at completely random times. 1pm, 2am, 6am. Only just started happening out of the blue. Can anyone explain where the sensors are? I’ve got a feeling it’s my bonnet that’s the problem, but just can’t figure out where or how to sort it. Garage told me I might need a new ECU so walked away from that straight away.

any help is much appreciated as It’s happening every night

cheers

Hi, to elliminate the bonnet sw as a possible cause of the problem
just remove it and put insulation tape
around it so it can’t short to ground.
Thats how it works. When you raise the bonnet the switch shorts to ground.
Cheers.

Might have covid-19.
Plug it in to a tech tool it should tell you which switch, how is the car battery, the bonnet be ok it be more like a door switch or boot switch.

Hi Josh,
Did you find the problem? I have a 2010 VE Omega wagon with same symptoms but after disconnecting the alarm horn found that maybe it is the immobilizer side of the system as it is operating the main car horns, headlights, and indicators... I have seen the odd ant in the car and wonder if there might be an ant nest in the immobilizer that is setting it off?
I initially had the car battery tested under load (showed 86% battery capacity) and under no load and it shows a float of around 12.6 V which the Hanes manual says is fine, even though the battery is nearly 7 years old. I'm hesitant to part with NZD$345 for a replacement SLA battery if it is not the root cause of the problem.
Saw a vid showing how to use WD40 spray for all the latches and then religiously exercise the doors/hatch/ and bonnet 10 times or so until the neighbors start looking at you weirdly... Didn't work.
