If you’re reading this, chances are you’re staring at a useless key fob wondering how it went from unlocking your car doors to not even turning on. Don’t worry, we’ve all been there! A dead key fob can be a real pain, but the good news is that charging it is usually a pretty straightforward process.
This comprehensive guide will walk you through the different ways to charge your key fob, explain why it might have died in the first place, and equip you with the knowledge to prevent this frustrating experience from happening again.
Different Types of Key Fobs and How to Charge Them
Before you start digging around for a charger, it’s essential to figure out what type of key fob you have. This will determine the best way to juice it back up. Key fobs generally fall into two categories:
Key Fobs with Replaceable Batteries
These are the most common type of key fob. They use a small, flat battery – usually a CR2032 – that powers all its functions. If your key fob has a small slot or groove on the back, it likely falls into this category.
To replace the battery:
- Locate the battery compartment: Look for the groove or slot on the back of your key fob.
- Open the compartment: Use a small flathead screwdriver or your fingernail to pry open the compartment.
- Remove the old battery: Gently pop out the old battery. Make note of how it’s positioned for the new one.
- Insert the new battery: Place the new battery in the compartment, ensuring the positive (+) side faces up (or as the previous battery was positioned).
- Close the compartment: Snap the compartment back in place.
- Test your key fob: Try unlocking and locking your car to ensure the new battery works.
Pro-Tip: Always replace the battery with the same type and model specified in your car’s manual.
Key Fobs with Rechargeable Batteries
Some modern cars come equipped with key fobs that have built-in rechargeable batteries. These key fobs typically have a small port for charging, often located near the key ring or under a cover.
To charge your key fob:
- Locate the charging port: Check your car’s manual if you can’t find the charging port on the key fob.
- Connect the key fob to a power source: Use the provided charging cable (usually a USB cable) and connect it to either a wall adapter, your car’s USB port, or a computer.
- Allow the key fob to charge: The charging time will vary depending on the model, but it’s usually a good idea to leave it plugged in for a few hours.
- Disconnect and test: Once you think it’s charged, disconnect the key fob and test it out on your car.
Pro-Tip: Avoid leaving your key fob plugged in overnight, as this can potentially reduce the lifespan of the rechargeable battery.
Why Do Key Fobs Die?
Understanding why your key fob died can help you prevent it from happening again. Here are the most common culprits:
- Dead Battery: This is the most obvious reason and the easiest to fix. Batteries have a limited lifespan and eventually run out of juice.
- Extreme Temperatures: Both extreme heat and cold can affect your key fob’s battery life. Avoid leaving it in direct sunlight or exposed to freezing temperatures for prolonged periods.
- Frequent Use: If you’re constantly using your key fob to lock, unlock, and start your car, the battery will naturally drain faster.
- Old Age: Just like any other electronic device, key fobs have a limited lifespan. As they age, their components can degrade, leading to battery drainage issues.
