What should I do if my key fob is dead?

Press the start button with the key itself. Some cars can still detect dead key fobs this way in emergencies. If it’s a cold day, go indoors and warm up the key fob with your breath. Sometimes, the temperature can mess with the electronics. If you have a second key fob, try using it.

Why is my intelligent smart key not working?

The ECU apparently only attempts to reprogram the remote functions on a cold boot and if the key fob is not within range, it won’t work. Both of my remotes were dead and I did this on each one – one at a time.
