Dealing with a dead car battery is never fun, but it’s especially frustrating when you don’t know why your key fob battery keeps dying. In this article, we’ll explore some of the most common reasons for key fob battery failure and offer some tips on how to extend your key fob’s battery life. So, if you’re dealing with a constantly dead key fob battery, read on. You may find the answer you’re looking for.
Why does my key fob battery drain so fast?
One of the most common reasons for key fob battery failure is a faulty or low-quality battery. If your key fob’s battery is more than a few years old, it may be time to replace it. The key fob battery life is very short, only lasting around three to four years. Depending on how often you use your car and the conditions in which you store it (for example, extreme cold or heat), your battery may die sooner.
Additionally, if you’ve been using your key fob frequently, the battery may be running low on juice. Key fobs typically have a very short life span because they’re constantly being used to unlock doors and start cars. If you’re using your key fob a lot, then it’s likely that the battery is wearing down faster than normal. Try conserving energy by locking your car manually instead of using the key fob.
Another common reason for key fob battery failure is water damage. If your key fob gets wet, the circuitry can become corroded and cause the battery to die prematurely. In order to prevent this from happening, be sure to keep your key fob dry at all times. If it does get wet, try to dry it off as quickly as possible and give it time to air out before using it again.
Finally, if your key fob isn’t working properly, there may be a problem with the circuitry. In this case, you’ll likely need to take your key fob to a professional to have it repaired. Do not try to fix it yourself, as you could damage the circuitry even further, especially if you are not familiar with how to do it.
How do you fix a dying key fob?
One way to fix a dying key fob is to replace the battery. If your key fob battery is dead, you can purchase a new battery from a store or an online retailer. Most batteries cost between $0.50 and $15.00, so it’s worth it to replace the battery if your key fob isn’t working properly.
Another way to fix a dying key fob is to clean the battery contacts. If the battery contacts are dirty, it can cause the key fob to not work properly. To clean the battery contacts, you can use a cotton swab and some rubbing alcohol. Just be sure to let the key fob dry completely before trying to use it again.
If the buttons on your key fob are sticking, you can try to lubricate them with a small amount of WD-40. However, you should only use a very small amount, as too much WD-40 can cause the key fob to malfunction.
If your key fob isn’t working properly and none of these methods seem to work, you may need to replace the key fob altogether, especially if the problem is with its circuit board. This issue is something that should be handled by a professional. Key fobs can be expensive, but they’re worth it if you rely on them every day.
What are the signs of a dying key fob battery?
The key fob battery is dying when you notice that the key fob isn’t working as well as it used to. For example, if you try to press the buttons and nothing happens, the key fob may not open or start the car or take multiple attempts to get it to work.
Other signs that the key fob battery is dying include a weakening signal in a shorter range. Difficulty locking or unlocking the car and a slow response time are also signs that the battery needs to be replaced.
If you’re experiencing any of these signs, it’s time to replace the key fob battery. The good news is that this is a relatively easy process and can be done without any special tools. All you need is a coin or screwdriver to remove the cover of the key fob.
Once you have the battery in hand, look for the model number and make sure you purchase a battery of the same type. If you’re not sure which battery to buy, take the old battery with you to the store.
Replacing the key fob battery is a simple process that should only take a few minutes. Be sure to dispose of the old battery properly and enjoy your working key fob.
How often should key fob batteries be replaced?
The answer to how often to replace key fob battery depends on the make and model of your key fob, as well as how often you use it. In general, most key fobs need new batteries every 12-18 months. However, if you use your key fob frequently or in a harsh environment, then the battery may need to be replaced more often.
If you want your key fob battery to last longer, there are a few things you can do:
- Make sure that the battery is properly installed and that you are using batteries that are compatible with the key fob.
- Keep the key fob in a cool, dry place.
- Avoid leaving the key fob in the sun or in a hot car. Exposing your key fob under these conditions can quickly drain the battery.
It’s important to replace key fob batteries regularly, as old batteries can leak acid and corrode the inside of the fob. This can damage the electronics and make the fob unusable. So if your key fob starts acting up or you notice that the battery is getting weak, it’s a good idea to replace it right away.
Conclusion
You’ve probably heard of the phrase, “a penny saved is a penny earned.” This holds true for your key fob battery, too. If you can save your battery by being conscientious of how you use it, you’ll be better off in the long run. Keeping spare batteries on hand is always a good idea, too. This way, you’ll never have to worry about being locked out of your car.
