Hello I am looking for instructions for a after market remote. It is a elvatoc
aps2k4saw.The vehicle I purchased 2002 Grand Cherokee Overland had this remote but it does not work to lock or unlock the doors or set the alarm.

You will have to contact the Company the remote is from. On other remotes I have used you have to buy a extra kit for the doors and another one for the alarm. It will be hard to tell if yours is already wired for doors and alarm without taking off the drivers door pannel and checking the wirring harness.
