After reading your post I watched the Youtube bypass video & it certainly looks like a flaw in the product. I am just back in the house after trying what was done in the video, I tried it 20 + times it did not bypass once, then i took the car out & when i got back tried it another 15 times again it did not bypass.
Not saying it is nonsense maybe it had not been installed correctly.
I looked at all types of aftermarket security & trackers & spoke to a few people on this site & in the end decided that if my car was stolen I would not want it back so went with the Ghost & Gap insurance, saves on annual subscriptions too.
The details of the company in my first post the lad had a BMW M2 & had it installed on his own car.
If they really want the Car nothing will stop them.
