Anti theft aids?

Push button generally means keyless which can be easily stolen with the likes of a signal booster. Have a look at the Autowatch Ghost, car basically won't start without a code put in (using buttons in the car) if you're overly concerned about it

The Aqua being easy to steal is the only thing that made it desirable to the thief. There are no absolutes of course, but likelihood is if the thief is going to the trouble of using a signal booster, I would suggest that they'd target something more expensive than a Note.

While the Ghost is fantastic technology wise, there's no point in spending over €500 one one for a Note. At the other end of the spectrum with a very expensive car, I'd be letting the serious gangsters take it while I was fast asleep (and track it later via GPS) rather than be woken up by a gang asking for the code.

Keyless theft is done by professionals who steal the cars to strip it for parts or export to other countries. Only high end cars are targeted for this.

Jap imports with no immobilisers are stolen by 17 year olds who just want to joyride the car and burn it out later that night.

Nissan Note can’t be stolen by joyriders since it has alarm & immobiliser, and it wouldn’t be a target for the kind of people doing keyless theft.

A medium chain and good padlock. Acts as as a 'move to the next one' deterrent. Beyond that, no matter how fancy the crook lock or bar zoke they will always find a way around it if they really want the car, quite often damaging the wheel \ dash in the process.

As a deterrent a disc lock is hard to beat (the one that covers the whole steering wheel). I've seen several tests done on them on TV/Youtube. Can only really be removed with power tools. Unless they really really want the car they won't bother.

Downside is they're a bit cumbersome putting on and off, but better than not having a car on a cold rainy evening.

An apple airtag costs about 20 euro once off and can track an object for a year and then it's battery needs replacing. It can easily be hidden in seat or headrest or dash etc. No ongoing fees except a new battery.

It won't stop car getting nicked but you can typically find it the next day which helps getting it back.

You need an iPhone to set it up, but you can use a friend's.

You can buy a shock car alarm for around 50 euro that connects to cars battery. It makes noise to scare away hopefully before they can get into car or pop bonnet. Easy DIY.

Any jap imports particularly with square registration plates scream steal me to joy riders.

Often keys are taken during house burglaries even while owners asleep upstairs so thrives may get key to car from inside house. They also use fishing rods through letter boxes to snare from hallway table.

Samsung and other manufacturers have their own too.

My own car can be tracked via GPS from the manufacturer, but as it relies on the mobile phone network, and hasn't got it's own independent and hidden power source, I don't think it will drop my insurance.

Just Samsung (with Samsung SmartThings Find enabled, but I think it is on most) as far as I know.

Samsung have a slightly higher market share than Apple, so in theory could be as good if not better, but in practice I'm not so sure.

When Google get around to releasing their AirTag competitor, compatible across all Android devices, it should have a better community to find things.
