Hi all, I just recently purchased a 1997 skyline r33 it had no alarm or immboliser, i am purchasing the mongoose m80G alarm, I want the doors to open with the alarm remote. Currently I am using the keys to open and close the doors - just wondering if anyone knows, will i also need to buy a central locking kit to make the alarm remote open the doors automatically or will the mongoose alarm open the doors automatically with the remote alarm? thanks
