Hey guys, I recently picked up a 1993 Lexus ES 300, and the key is missing the back piece that clips on and holds the battery in place to work the remote for the automatic locks. I called my local Lexus dealership, and they pretty much no help, actually seemed confused to what i was asking for. If any one can help me out or steer me in the right direction i'd appreciate it. I searched ebay, and that was another dead end...
