DX has immobilizer, you can see immobi sticker on driver side window glass (sticker having image of car with a "taala" on it)
its v much secure, with immobilizer car wont start by any other key as mentioned above, but I read somewhere on PW that immobilizer can also be breached, but dont know that Pak car lifters have this tech or not...
you can use steering lock rod (like that of crook lock) as an additional security..
