A closer look at the key fob

Key fobs use low-frequency radio waves to communicate with the electrical brain of the vehicle. This quick way to start, stop, lock, and unlock your Mustang is a technology that is constantly improving with every model year.

Like any technology, there are advantages and disadvantages. On the plus side, it's quick and easy to use. You'll also have one less key to carry around with you.

Key fobs make it nearly impossible for someone to steal your vehicle. This theft deterrent system is almost impossible to override and is a giant plus for those who choose to have it.

On the other hand, replacing a missing fob isn't necessarily cheap. A replacement must come directly from the manufacturer and can cost as much as $100.00. Then you'll have to program the new one so that it will work—more on how to do that ahead in this post.

How do you start a 2020 Mustang with a dead key fob?

Being in a hurry to get somewhere, only to find out that your Mustang's key fob is dead. If this happens to you, we can help you get back on track by following a few simple steps.

Each smart key fob has an actual mechanical key hidden inside of it. To access it, you'll need to use your fingernail to open the slide lever. This lever is located on the top of the fob.

When the fob cover is removed, you'll see the mechanical key tucked away on the inside. Carefully remove this key, and set the fob aside.

On the driver's side door handle, a keyhole is hidden on the right. You'll see a slot here. Insert the key blade into the slot, and remove the cover. You'll now see the keyhole slot. Insert the key into the slot and turn it a quarter-turn clockwise. The driver's side door is now unlocked and can be opened. 

Once inside the car, you'll need to get it started. Locate the mechanical key slot by removing the rear cupholder between the driver's side and passenger side seats. Once this rubber cover is removed, you'll see where to insert the key fob. Place the key fob here, with the buttons facing forward. The car's electrical components will recognize the fob, even though the batteries inside the fob are dead.

The car will now start. Once it's started, remove the key fob and replace the cup hole cover. Be sure to get the fob's batteries replaced as soon as possible.

Does the 2021 Mustang have a remote start?

Remote start is available as an upgrade for the 2021 models. Ford is the only non-luxury automaker to offer a service of remote start for free with the premium package. This service, known as Ford Pass Connect, will allow you to start your Mustang via an app on your smartphone or tablet. This service will also allow you to track your mileage, fluid levels, and maintenance schedules.

In Closing

Keyless start and entry are convenient for the consumer. This technology also makes vehicles much more difficult to steal, as they will not start without the fob assigned to that particular car. While there are some disadvantages, such as occasionally replacing the batteries, they are far outweighed by the benefits. For safety's sake, keep your spare key fob in a safe place, so you'll have it at the ready when and if you need it.
