try calling a chrysler dealer with the key fob part number 4602260. this part number fits several older cars such as intrepids and concordes. I own a chrysler salvage yard and found these on intrepids. the dealership can give you all the cars that use these remotes. I actually got one given to me at a chrysler dealership that needed a battery. they will need to be programed by the dealer new or used. hope this helps as they are not a rarity at all. James
