Cars have 'secret button' that starts engine even if your key fob dies
Nowadays most modern cars don't come with a traditional key as keyless technology grows in popularity.
However, these electric key fobs can cause chaos for drivers. We all know the panic that comes over when we press our car fob and nothing happens. The battery has died and we can't fix it.
Most drivers are unaware that most the majority of cars now have a hidden button that lets you fire up the engine even when your fob is broken.

According to car experts at Plates Express, this function is built into many vehicles, yet many people do not even realise it exists.
According to Nottinghamshire Live, knowing this trick could mean the difference between getting back on the road or being stranded. A 2023 survey found that more than 60 per cent of drivers with push-button start systems had no idea their car had a hidden emergency start feature.
That means millions of people could be unnecessarily calling for roadside assistance or locksmiths when they could start their car themselves. Fob batteries can drain faster than expected, especially in extreme temperatures or if buttons are accidentally pressed while in a bag or pocket.
Knowing how to locate and use the emergency start feature could save you time, money, and stress.
The location of this feature varies by manufacturer, but in most modern vehicles, you’ll find it in one of these places:
On the start/stop button itself. Some cars have a built-in RFID reader that still recognises the fob when it’s pressed directly against the button.
Inside the centre console or armrest. A small slot or pad designed to detect your fob, even if its battery is drained.
Near the steering column. Some models have an emergency key fob reader positioned under or beside the steering wheel.
In the glovebox or under the cupholder. A discreet sensor designed for backup ignition.
Most manufacturers, including Ford, BMW, Volkswagen, and Toyota, have incorporated this hidden feature into their designs.
How to start your car with a dead key fob
If your key fob dies, follow these simple steps to get your car running:
Find the emergency key slot or backup sensor. Check your car manual or look in common locations like the start button, centre console, or steering column.
Place the key fob directly on or near the sensor. Even without power, the fob can still be detected using passive RFID technology.
Press the brake (or clutch) and push the start button. The car should recognise the key and start as usual.
Replace the key fob battery ASAP. While this trick works in an emergency, it's best to replace the battery to avoid future issues.
