I have a 04 Rav4 . I recently purchased this car and it did not have a remote for the door locks. I purchased one and tried to program it. The program method is quite intense however.. I think I was doing it right.. However it never entered program mode. I am questioning if the remote door locks were standard equipment on the 04 Rav4? How do I find out if my vehicle is suppose to have a remote door lock device. Any information on this line would be appreciated.
