For someone who likes gadets suprisingly Im not a great fan of all these "all singing and dancing" modern alarms
The way I see it alarms have two functions -
1 vibration /entry ......... to me this isnt much use even if they go off no one usually bothers and by then its often too late anyway
2 The immobiliser part ........A useful thing but its easy to sort this without paying a fortune for something that often drains the battery . Quite important as I dont drive the stagea every week.
I dont have an specific alarm on the stagea

but..............
When I leave it anywhere for any length of time I just disconnect the fuel pump (it has its own seperate circuit) and I turn the launch control to zero .
I always do the latter whenever I leave the car.
Even someone hardwires the pump (unlikely) it starts but wont rev or pull away and makes a seriously loud noise popping back as it limits the revs.
A lot of expensive cars are now stolen to order. Often the theives break into the house just to get the keys and then simply drive off.
So even with the keys mine cant be driven off - but I do keep them safe as a precaution.
