i had to change the door on my 1998 grand cherokee laredo, now the security light is on, and my jeep wont start. how do i fix this?

Did you have the door open for a long time? If so the battery is probably dead. Charge the battery or try to jump start it. Doing this should get you back on the road.

be sure you have a charged battery. close all doors. go to passenger side door and lock/unlock door twice with the key from the outside this is the way to factory reset the oem security system

let me know how you make out
