How do you replace door handles on a new VW beetle?
If it is like most other VWs , there is a philips screw on the edge of the door where it latches. if this is removed the door handle can be slid out. You didn’t mention if there is a key lock in the handle. Use the key in cylinder from the old lock to replace. You may also have to turn the key in order for the slot to mate in the door mechanism.
