We received an inquiry from a driver with a 2006 Hyundai Tucson asking about the correct replacement remote for his vehicle. That keyfob is Remotes Unlimited part 806-1806. This 3-button remote, with a panic button on the back, has FCC ID OSLOKA-320T. Early versions of this transmitter have a red LED light at the top, but the case covers this light on the later versions. You can see and purchase this part at the following link:
RUI 806-1806 with FCC ID OSLOKA-320T
Please note that Tucson vehicles which use this remote require a scan tool for programming a new remote to work with the vehicle.
