dont know, maybe u can check it in product details online
but like other systems, i guess just remove wire from battery, y go as far as jamming the signals
waise b if u r in a class, n u see remote vibrating i wonder if u'll go outside to check the car or just press lock button to silent it
as far as chains go, first thing is chains use lock in the end, either they can do the easy thing, cut the lock or else just cut the chain, though i also chain one car parked outside, something is better than nothing
