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

The keyless car is a marvel of engineering. But how is it that they can start even when the battery in your key fob goes dead? The answer lies in science.

There’s usually a mechanical key hiding inside the key fob for cars with push-button start systems, so you can still unlock your door if the car battery or your fob battery runs out of juice.

A 2023 survey found that over 60 per cent of drivers with push-button start systems had no idea their car had a hidden emergency start feature.
