Hi I have an 01 honda civic ex coupe and recently my door lock hasn't been working. When I go to click the button to unlock the car neither door will unlock. I have had to use the key to unlock for the last few weeks. Using the key isn't a problem but I would rather like to have the key less entry to open my car.. And I am thinking of getting an aftermarket security system for it. Does anyone know any good systems on a side note? Thank you.
