“Regular maintenance, including periodic battery replacement, can extend the life of your key fob and prevent unexpected issues,” adds Smith. “Investing in a high-quality battery can also make a difference in the long run.” If you have a 2016 Toyota Corolla and experience issues with your key fob, you might find our article on 2016 Toyota Corolla key fob not working beneficial.
