Sounds as though you were using it wrong, I lock my van with Citroen key fob, that central locks all the doors, I then press the Strikeback blue fob and fires the alarm up, reverse to switch off, I am not sure what hoops you needed to jump through?The non starter is very effective and definitely gives peace of mind, but it was incredibly frustrating to use on a journey.
Every time the ignition is turned off, we had to either dig out the hidden key fob, or go through the smart phone override process. So if we filled up with diesel, we had to go through the disabling process again. Stop for lunch, and yep, you’re disabling the non starter again.
It became so impractical on a journey that i put the non starter into service mode at the start of the journey and hoped I’d remember to disable service mode at the end of the day.
In contrast, our current system has a completely transparent immobiliser engagement/disabling process. It just works without us jumping through hoops every time the ignition is turned off. Also the 24 hour monitoring service can remotely disable the engine, if need be.
