A dead battery in your Ford key fob can leave you stranded. Luckily, replacing it is usually a quick and easy DIY job. This guide will cover everything you need to know about Ford key fob batteries, from identifying the right replacement to step-by-step installation instructions.
Why is My Ford Key Fob Not Working?
Before assuming your Ford key fob battery is dead, it’s essential to rule out other possibilities:
- Check the battery contacts: Over time, the battery contacts inside the key fob can become corroded. This corrosion can prevent the battery from making a good connection, leading to a malfunctioning key fob.
- Try a spare key fob: If you have a spare Ford key fob, try using it to unlock and start your vehicle. If the spare key fob works, it’s a strong indication that the battery in your primary key fob is dead.
- Examine the key fob for physical damage: A damaged key fob, such as one that has been dropped in water or crushed, may not function properly.
If you’ve ruled out these possibilities, it’s likely time to replace the battery in your Ford key fob.
What Kind of Battery Does a Ford Key Fob Take?
Most Ford key fobs use a small, flat, round battery known as a CR2032 battery. You can typically find this type of battery at most grocery stores, drugstores, and auto parts stores.
