My Father Had Left Me His Jeep When He Pasted Away Last Week. He Was Having Problems With The Security System When He Had It. But He Used To Do Something With The Battery And Then The Key Lock On The Door. Now I Have This Vehicle. And When I Turn The Engine Off The Inside Lights Still Stay On, And Sometime The Information Center In The Dash Above The Shifter Does Not Work Now, And The Heater Does Not Work Hot. But It Stays On Now But Blows Cold Air. And The Remote Key Locks Never Worked Either When He Got The Jeep Either. How Can I Reset This System So I Do Not Have To Keep Taking The Battery Cable Off?
