I have a 2002 ex sedan with a v6 i want to but a remote for keyless entry but they say to make sure i have a factory keyless entry system installed...how can i do this? thanks 6thgenners!
If I'm not mistaken all EX's had keyless. I would see if you can track down an old catalog or spec sheet to verify. I think the OEM relay pack is inside the dash on the passenger side. When I would install an aftermarket keyless I would tap onto the unlock and lock wires in the driver's side fuse panel. There should be a grey plug with two wires in it plugged in if you have the OEM version (though I'm 100% on this).
The SE could go either way. It seems like it would have been included but who knows for sure. I would wait and see if someone with an SE will respond. Like Red stated above if you've got the light on the door panel then it should have been a part of the package from the factory.
My SE 2000 has it. Test by Locking the car by pushing the knob. Close door sit inside, Pull knob and open. If It goes off, Insert key into door and turn to disable alarm.
