I replaced the ignition switch for my Yukon , it for the most part it just crank

The keys that I have for my Yukon aren't chipped. Will it make a difference? How do I do the relearn? The security light finally went out and still no start

how do i do that

Probably need to tow it too the nearest Chevrolet dealer

IF ONLY I COULD. I PUT A NEW LOCK CYLINDER WITH NEW KEYS AND DID THE RELEARN. IT WORKED FOR A WHILE NOW PO341 CODE AFTER TUNE IP
