The car key fobs are pretty smart, but that does not mean they won't sometimes get stuck in the "not responding zone". If this happens, it's usually time to replace the battery. But that doesn't always solve the issue, as you could also have a problem with the connection on one of the battery connector terminals.

The car makers are aware of the possibility of a issue, and frequently install an extra mechanical key in the fob to be used in an emergency. It is accessible by pressing the small release button or latch on the back of the fob. (Check the user manual for more details).

Be sure to purchase the button cell battery (which looks like a tiny silver coin) for your fob, and follow the user's guide or video on how to remove the old one. Then, replace the new battery in the same orientation that the old one was placed (the positive side should be facing upward toward the buttons). After reassembling the fob, test its lock/unlock and start functions to be certain the new battery was placed correctly.
