A key fob is a device that will use a lot of energy, and its batteries will not last long. If the battery in your key fob battery is running low, it will not be able to properly interact with the receiver, as the connection might become intermittent.

Key Fob Isn't Programmed Correctly For The Vehicle

To work effectively, you must correctly configure the key fob for the vehicle. If changing the battery in your key fob does not help, the key fob may not have been set up correctly for the car, or your car battery is weak or empty.

Your Car Battery is Weak or Dead

One of the reasons why the car does not recognize your key fob is because the car battery is nearly dead or weak. You should always check your car's battery so you can immediately change it if it's damaged or dead.

Sometimes the problem is not with the key fob but with the car. Modern automotive systems are demanding, which can cause the battery to weaken or die.

A dead or weakened battery will prevent it from responding to the key fob. Charge the battery and consider replacing it when it is old and worn out.

Radio Interference

If your key fob suddenly stopped working, radio interference could be the cause. Wireless devices that transmit on the same frequency as the key fob, such as radar detectors and intruder alarms, can interfere with the signals of the key fob.

Buttons Loose

It is also possible that the problem lies with the buttons. Most key fobs have rubber buttons that can loosen or wear out over time. If one or more of the buttons do not pop out properly or are stuck, you can follow along these steps to fix the buttons:

  1. Unscrew the case
  2. Remove the buttons
  3. Clean them
  4. Reassemble the key fob.

If this doesn't work, you may need to buy a new key fob.

When Should I Reset My Ford Key Fob?

  3. Put the key in the ignition, turn it to the on position, push the key fob's lock button and release it.
  4. Turn the car off and take the key out of the ignition. If the reset worked properly, the doors should now unlock and lock.

If you've tried everything and still can't get your fob to work, it's time to replace it. The cost depends on several factors. The most significant factor is whether the dealer does it or you do it yourself.

However, if you decide to replace your Ford Expedition key fob, you will probably pay between $20 to $60 for a new one. The cost depends upon where you buy the key fob.

Starting The Ford Expedition With The Backup Slot

If your key is damaged, the first thing to do is determine the nature of the problem and whether it is easier to repair the key fob or replace it entirely.

There are several approaches that can be used. If the key is near metal objects or electrical devices such as cell phones, or the key's battery is dead, the keyless starting system may not work.

If you cannot start your car, try the following:

  1. Insert the backup key into the backup slot.
  2. The backup slot's position varies, but in a Ford Expedition, you can find it in the front cup holder, and you need to remove the rubber piece in the bottom.
  3. Place the key in the backup slot position upside down and the button facing the rear of the vehicle.
  4. To start your car, press the brake pedal with the key in this position, then the push-button ignition switch.
