How To Change Ford Car Key Battery

The key fob that comes with your Ford vehicle is battery powered, which means that at some point it will have to be replaced. This won’t happen often, but when it does it’s important to know how to change it as the key fob is the tool that allows you to remotely lock and unlock the vehicle.

Step One

The first thing you’ll need to do is release its key blade. For some Ford models it will be necessary to manually extract the blade, while others use a special release button.

Step Two

Now you’ll want to apply a screwdriver which is flat to pry your key fob open. Insert the screwdriver’s end into the key’s side, where its key blade usually rests. Gently extract its cover which will reveal its battery. For key fobs that require you to extract their blade, you can also use a coin to wedge inside the gap near the key, and then twist until the cover pops off.

Step Three

Next, take the screwdriver than use it to pry the battery out. It can be difficult to get to at first since batteries are smooth and flat, but using a screwdriver to pry it out will work on most key fobs.

Step Four

Now you want to insert the replacement battery. Just place it within the identical position as the older battery, while ensuring its plus side is up. If the new battery is installed upside down, then the key fob won’t function properly.

Frequently Asked Questions

How can I program my Ford’s personal entry keyless code?

To create your personalized entry code you’ll first want to input a factory set code which is five digits. Next, click 1•2 in its keypad within 5 seconds, then input the 5 digit code you want to use. Bear in mind that every number must be inputted within 5 seconds of one another. Then click 1•2 in your keypad so it saves the personalized code one. The car doors will unlock and lock to verify that the entry code has been correctly programmed.

What happens if I don’t replace my key fob’s battery?

Once the battery completely dies you’ll no longer be able to remotely access the vehicle. Many Ford models include emergency keys that you can use to get inside, but of course physical keys are vulnerable to be stolen, lost or copied and if a thief gets their hands on your physical key they can enter the vehicle and steal it.

Key fobs have become a popular alternative to traditional keys because they are easy to reprogram, and if the fob gets stolen or lost, replacing it is easier and more cost effective than conventional locks. The good news is that even a basic battery is enough to keep the key fob powered for quite some time, and Ford is developing newer technology that allows key fobs to be powered without the need of batteries, mainly through magnetic fields which are transmitted between readers and antennas.
