Dose look very cool but is potentially just as weak as the one above, it could be very easily over come by down loading the app and running it through a few special programmes to crack your code/username and matching it to the frequency of your transponder in the car . Would take a while to work out but could be done .
I think after reading morein to these systems I will retract my statement and won't be buying one until they can be proven to be just as Secure as factory =( they look so cool tho
