Similar to the problems described for various other XPS models, my XPS 15 9530 has been skipping keys for months. I have to press very long and hard for certain keys to trigger. This has been solved in the 9570 BIOS update, but I am not aware of any BIOS update for the 9530.
Thanks for posting. Apologies that your system is not performing as expected.

If there are no errors then it may be a software issue. Here are some things you can try from the Dell knowledge base:

I appreciate the kind reply, but it is well established at this point that this is not a hardware issue. This affects many Dell models and they are working on BIOS updates to fix the problem for other laptop models. I just want to ensure that my laptop model is among them.
Unless the problem has existed since you've owned the system - and particularly given that it's 5+ years old -- it's more likely either a keyboard in need of a thorough brush-out or one with worn key switches that needs replacement.
The newer systems use a completely different keyboard design from the old ones - this is not a BIOS issue. It's a hardware fault.
Debris under the keys couldn't explain this. The symptoms were not there one day and then they were the next. This isn't an isolated issue either, but affects a good portion of the keys. The timeline of the symptoms appearance also lines up with the issues on the other Dell models.
Have you tried troubleshooting with an external keyboard? Do you have the same issues? This would help rule out whether it's a hardware or a software issue.
For further assistance with this, please send your Service Tag number privately so I can reference your system. Thanks.
