There is no way we can tell you what lug locks would be used on your 2019 Geo Pro 15TB is. What you're going to need to do is measure the lug studs on the trailer when you pick up the trailer.

The most common sizes are: 1/2"-20 short # 12CLN, 1/2"-20 long # 12CLN-L, 9/16"-18 # 6-53, and 5/8"-18 # X1148.

Once you've determined what size lug nuts you have, you can determine which locking lug nuts will work for you. For example, the Wheel Lock Set for 1/2" Wheel bolt # RG01-150, which will fit 1/2"-20 lug studs.
