Sad story

Porsche is made by Volkswagen but they don’t use the vw logo on Porsche keys

Yes. They certainly do not. BUT- it is possible to cut a VW key for a Porsche. For instance an HU key blank fits a wide range of cayenne’s, 968’s, some boxsters; and almost all the newer VW cars. Many cars that aren’t even related by family tree use the same basic key blank- although it’s more common for blanks to be shared by “relatives.” Even when keys switch from older non transponder units to new “chipped” keys, of fancy flip out keys- even the “emergency spare” in some “smart keys” is the same and functionally the same as an older key. A non chipped key won’t start a car with a chip, but will turn all locks the same. Sometimes a chip from another make won’t work, and often the remotes won’t. What matters is the actual key shape identifier, and in some cases even a non identical number key will be close enough to still work fine. With remotes the FCCiD is the primary factor, the next being protocol.

Tl:dr- many Porsche’s share key designs and specs with VW, so while Porsche doesn’t use VW branded keys, you could buy a (likely cheaper) VW key and use it on a Porsche providing the car and key you select are compatible applications.

TLDR although the post makes us believe the girl is lying, and it very may be that she is lying, it is also very possible that she’s telling the truth, and the only true way to know is to take that key and see if it starts it
