Bought these as all my TPMS sensors were bad. Founded a local tire shop. You couldn't force them to program. A little research on the internet and I found out that you have to do different air pressures in each tire divided by 3psi for Nissan to register them. Once they get the PSI back to what the door says. I did 36-33-30-27 DF-PF-PR-DR. Used a paper clip to start learning and drove for 15 minutes and the lights went out programmed.
