Keyless entry system

I have a 2001 Isuzu Rodeo with power door locks(button is on door switch panel). When I bought the car I did not receive any remote units with the car. I do not have a chipped key for the ignition. My question is ......is there a remote that I can buy and have programed to use to unlock the doors by remote? I'm not sure if the car is equipted to use a remote, but since I do have electric locks I summize that it is set up for remote locks. Any help would be appreciated. I am thinking of going the remote starter way and having them include the door locks as part of the system. Thanks for for any replies on this matter 2001 Rodeo 4x4 V-6 Automatic :smokin:

If you have power locks there is a good chance you have wireless ones too.... check out ebay to buy a used factory remote and then check my isuzu FAQ link below to see how to program it ...
