You might think, not again such a question where are already thousands of topics about. However, I've not been capable of finding the answer I needed to fix this problem.
None of these topics go as deep as the Keychain.
When I'm trying to deploy my app to an iPhone, I'm receiving the following message:
Code Sign error: The identity 'iPhone Developer: [Name] ([ID])' doesn't match any valid, non-expired certificate/private key pair in your keychains.
Now, as said, I have been looking for multiple guides or fixes, however, none of them seemed to fix this issue.
Things I've tried:
After trying all of these ways, I've still not been able to solve the issue. One problem I've seen is that at first hand, the certificate in the Keychain was showing an invalid status, which is now solved.
However, if I'm right, there are supposed to be two keys attached to the certificate. A public and private key, and these are not showing.
Neither are there any keys showing in the Keys tab in the Keychain Access.

Provisioning profiles installed on the devices or signed with for the target might not be valid, try to go to Organizer->Provisioning profile
and see if the profiles have the valid status? if not try to delete & refresh them, if they appear valid after refreshing then it might solve your problem if not then you should remove all the entries from keychain
and delete profiles on your provisioning portal and try to create from scratch, if you still face the problem then take help from step by step guide tutorial
