This one has a life time limited waranty on it but has no name brand or contact info. My buddy tried to go cheap. I installed the damb thing in an Wagon-R and it partly worked. The door locks malfunctioned. And now he cant get his money back. And I wasted my time. If you want an alarm get something that has a good reputation and a waranty. Oh and something with a brand name on it. Because I think Cheap + electronics= garbage……m I right??
