My car has a siren, car lock is also particularly reinforced, and the lock is the key chain model, my car on the mall below, people come and go so much, can be stolen, really amazing
Alarm is useless, I was so ten minutes did not work hard, just bought two months of gas dead, it is estimated that the tram power and then open the explosion, the alarm sounds mostly rely on the power of the tram itself, the chain lock But also easy to burst but also good, that is, can not be casually carry away
