Keyless remote

2002 Sebring LX..automatic,less than 100,000 km's on it..power windows and locks... what do I need to have installed for keyless door lock/unlock to work on this vehicle? can i just pick a key up and program it to work on the car or does a dealer need to install something?

Your car needs to have the proper body control module to be able to just program the remote. Vatozone/Pepboyz sell a kit for about 100$ to outfit your vehicle with everything you need for keyless remote.
