A car expert reveals how one can start their car with a dead key fob, even if their car has keyless ignition.

Don't panic if your key fob dies and you don't have a replacement battery. These little-known methods will get you back on the road.

In some cars you can even start the ignition without putting in the key. On most days, this is convenient - but what happens if the battery that powers the transmitter in the key fob dies?

If you have a newer car, you may have a battery-powered smart key with a lot of really convenient features. But what do you do if that battery dies?

If a visual of the battery replacement is needed, the YouTube video on changing the battery in a mid-to-late 2010s Chevrolet Equinox key fob shows how to pop the battery out and place in the new one.
