Key fobs have become an indispensable part of modern life, offering convenience and security for accessing our vehicles. But what happens when that little device starts to fail? One of the most common culprits behind a malfunctioning key fob is a dead or dying battery. So, the question arises: Does AutoZone, a leading automotive parts retailer, sell batteries for key fobs? The short answer is a resounding yes! But there’s much more to know than just that simple affirmation. Let’s delve deeper into the world of key fob batteries and AutoZone’s offerings.
Understanding Key Fob Batteries
Key fobs, despite their sophisticated functionality, rely on a simple power source: a small, coin-shaped battery. These batteries are typically lithium-ion and come in various sizes and voltages. Knowing the specific type your key fob requires is crucial for a successful replacement.
Common Key Fob Battery Types
The most frequently encountered battery types for key fobs include CR2032, CR2025, and CR2016. These codes indicate the battery’s physical dimensions. The “CR” signifies that it’s a lithium battery, the first four digits (e.g., “2032”) indicate the diameter (20mm), and the last two digits indicate the thickness (3.2mm in the case of CR2032). You’ll also occasionally find other less common types, so always double-check.
Why Key Fob Batteries Die
Key fob batteries, like all batteries, have a limited lifespan. Several factors contribute to their eventual demise. One primary reason is usage. Each press of a button on the fob draws power. Frequency of use directly impacts battery life. Also, proximity to the car can cause constant communication between the key fob and the vehicle which can drain the battery. Furthermore, extreme temperatures can negatively affect battery performance. Cold weather, in particular, can significantly reduce battery life.
AutoZone’s Key Fob Battery Selection
AutoZone recognizes the importance of functioning key fobs and stocks a wide variety of batteries to meet the needs of most vehicle owners. You’ll find options from reputable brands, ensuring both quality and longevity.
Brands and Availability
AutoZone typically carries key fob batteries from well-known brands like Duracell, Energizer, and their own private label, Duralast. These brands are known for their reliability and consistent performance. The availability of specific battery types can vary depending on the store location and current stock levels. It’s always a good idea to check online or call ahead to confirm that your needed battery is in stock.
Finding the Right Battery at AutoZone
Locating the correct battery for your key fob at AutoZone is generally a straightforward process. You can either browse the battery aisle in the store or utilize the AutoZone website or app. The online platform allows you to search by battery type or even by vehicle make and model, ensuring compatibility. Many AutoZone locations also have knowledgeable staff who can assist you in finding the correct battery.
Replacing Your Key Fob Battery
Replacing a key fob battery is often a simple DIY task that can save you time and money compared to going to a dealership or locksmith. However, it’s essential to proceed carefully to avoid damaging the key fob.
Tools and Preparation
Before you begin, gather the necessary tools. Typically, you’ll need a small flathead screwdriver or a similar tool to pry open the key fob casing. A soft cloth can also be helpful to protect the fob from scratches. Ensure you have the correct replacement battery on hand. Working in a well-lit area is crucial for clear visibility.
Step-by-Step Replacement Guide
- Open the Key Fob: Carefully inspect the key fob for a small notch or seam. Use the flathead screwdriver to gently pry the casing open. Avoid excessive force, as this could damage the plastic.
- Remove the Old Battery: Once the fob is open, you’ll see the battery. Note the orientation of the battery (the positive and negative sides). Use the screwdriver (or your finger, if possible) to gently remove the old battery.
- Insert the New Battery: Place the new battery into the fob, ensuring it’s oriented correctly (positive side up or down, as noted earlier).
- Close the Key Fob: Carefully align the two halves of the key fob casing and snap them back together. Ensure the casing is securely closed.
- Test the Key Fob: Test the key fob to ensure it’s functioning correctly. Lock and unlock your car doors to confirm the battery replacement was successful.
Potential Issues and Troubleshooting
Sometimes, even after replacing the battery, the key fob may not work immediately. This could be due to a few reasons. One possibility is that the battery wasn’t inserted correctly. Double-check the battery orientation. Another issue could be that the key fob needs to be reprogrammed. Refer to your vehicle’s owner’s manual for instructions on how to reprogram the key fob. If you’re still experiencing problems, consult a qualified locksmith or mechanic.
Beyond Batteries: Other Key Fob Services at AutoZone
While AutoZone primarily focuses on selling batteries, they may also offer other related services or products for key fobs, depending on the location.
Key Fob Replacement Shells
Over time, the plastic casing of a key fob can become damaged or broken. AutoZone may sell replacement shells that allow you to transfer the internal components of your old key fob into a new, undamaged casing. This can be a cost-effective alternative to replacing the entire key fob.
Key Cutting and Programming (Limited Availability)
Some AutoZone locations may offer key cutting and programming services. This is more commonly associated with traditional keys, but certain locations might have the capabilities to program some types of key fobs. It’s best to contact your local AutoZone to inquire about these services.
Cost Considerations
The cost of key fob batteries at AutoZone is generally quite affordable, especially when compared to the cost of replacing the entire key fob.
Battery Price Range
Key fob batteries typically range in price from a few dollars to around ten dollars, depending on the brand and type of battery. Purchasing a multi-pack can often provide even greater savings.
DIY vs. Professional Replacement Costs
Replacing the battery yourself is significantly cheaper than having a professional do it. Dealerships and locksmiths can charge a substantial fee for key fob battery replacement, often including labor costs. By doing it yourself, you only pay for the battery itself.
Extending Key Fob Battery Life
There are several strategies you can employ to help prolong the life of your key fob battery. Simple changes in habits can make a noticeable difference.
Practical Tips and Tricks
Avoid storing your key fob near electronic devices or metal objects. These can interfere with the signal and cause the fob to constantly transmit, draining the battery. Keep your key fob away from extreme temperatures. Avoid leaving it in direct sunlight or in a freezing car. If you have a spare key fob, consider using it alternately with your primary fob. This can help to distribute the usage and extend the life of both batteries.
Signal Interference and Storage
As mentioned earlier, signal interference can significantly impact battery life. Try to store your key fob in a location where it’s less likely to be exposed to strong electromagnetic fields. Some people even suggest using a Faraday bag to block all signals when the key fob is not in use.
In conclusion, AutoZone is indeed a reliable source for key fob batteries. They offer a variety of brands and types to suit most vehicles. By understanding the basics of key fob batteries, learning how to replace them yourself, and implementing strategies to extend their lifespan, you can save time, money, and frustration. Remember to always double-check the battery type required for your specific key fob and to follow the replacement instructions carefully. A little preventative maintenance can go a long way in ensuring the continued functionality of your key fob.
