Is your car key fob starting to feel unresponsive? Do you have to press the buttons multiple times to lock or unlock your doors? Like any battery, the one in your key fob will eventually wear out. When that happens, you’ll need to decide where to change your key fob battery. You have a couple of choices: tackle it yourself or seek professional help. Let’s explore both options to help you determine the best course of action.
Option 1: The DIY Approach to Key Fob Battery Replacement
For many car owners, replacing a key fob battery at home is a completely viable and cost-effective solution. It’s often simpler than you might think and requires only a few basic tools. If you’re comfortable with minor DIY tasks, this could be the quickest and most budget-friendly way to get your key fob working like new again.
Here’s what you’ll generally need for a DIY key fob battery replacement:
- A small, flat tool: A watch knife or a thin flathead screwdriver works well for carefully prying open the key fob case.
- The correct replacement battery: Most key fobs use common coin cell batteries, often CR2032. You can usually find the battery type indicated inside the fob itself or by checking your owner’s manual.
- A small Phillips head screwdriver (possibly): Some key fobs have tiny screws holding them together.
- Tweezers (optional but helpful): Tweezers can make handling the small battery easier.
The process is usually straightforward:
- Open the Key Fob Casing: Use your flat tool to gently pry open the seam of the key fob.
- Identify and Remove the Old Battery: Take note of the battery’s orientation (+ side up or down) before removing it.
- Install the New Battery: Place the new battery in the same orientation as the old one.
- Close the Key Fob Casing: Snap the case back together until it’s securely closed.

Choosing the DIY route offers several advantages. It saves you money on labor costs, and you can often complete the replacement within minutes, right in your own driveway. Plus, replacement batteries are readily available at most drugstores, supermarkets, and online retailers.
Option 2: Professional Key Fob Battery Replacement Services
If you’d rather not handle the battery replacement yourself, or if you’re unsure about the process, professional services are readily available. Several types of businesses can change your key fob battery for you:
- Car Dealerships: Dealerships are a reliable option, especially if you want to ensure the use of genuine parts or if your key fob requires reprogramming after battery replacement (though this is rare for simple battery swaps).
- Auto Repair Shops: Many general auto repair shops offer key fob battery replacement as part of their services. They have the expertise to handle various car makes and models.
- Battery Specialty Stores: Stores specializing in batteries, like Interstate All Battery Centers, are excellent resources. They not only sell a wide variety of batteries but also often provide battery replacement services for key fobs.
Opting for professional replacement offers convenience and peace of mind. You benefit from the expertise of trained technicians who can ensure the job is done correctly. In situations where your key fob is complex or if you encounter any issues during DIY attempts, professionals can provide the necessary support and solutions.
Where to Purchase Key Fob Batteries
Whether you choose DIY or professional replacement, you’ll need a new battery. Fortunately, key fob batteries are widely accessible. You can find them at:
- Retail Stores: Drugstores, supermarkets, and general retailers like Walmart or Target usually stock a selection of common coin cell batteries.
- Online Retailers: Websites like Amazon and specialty battery retailers online offer a vast selection of battery types, often at competitive prices.
- Battery Specialty Stores: Stores like Interstate All Battery Center are dedicated to batteries and carry a comprehensive range of key fob batteries, ensuring you find the right type for your vehicle.
Before purchasing, it’s always a good idea to double-check the battery type required for your specific key fob. Look for markings on the old battery or inside the key fob casing. Your car’s owner’s manual can also provide this information. Common key fob battery types include CR2032, CR2025, and CR1632, but variations exist depending on your car’s make and model.
Cost Considerations for Key Fob Battery Replacement
The cost of changing your key fob battery can vary depending on whether you choose the DIY or professional route.
- DIY Cost: If you replace the battery yourself, the cost is minimal. A replacement coin cell battery typically costs just a few dollars.
- Professional Service Cost: Professional key fob battery replacement will involve labor costs in addition to the battery price. The total cost can range from $20 to $50 or more, depending on the service provider and your location. Dealerships may sometimes charge more compared to independent repair shops or battery stores.
While DIY is clearly the cheaper option, professional service might be worth the extra cost if you value convenience, lack confidence in DIY repairs, or need the assurance of expert handling.
Making the Right Choice for Your Key Fob Battery Change
Deciding where to change your key fob battery ultimately depends on your personal preferences, comfort level, and budget.
- Choose DIY if: You are comfortable with simple tasks, want to save money, and prefer the quickest solution.
- Choose Professional Service if: You prefer convenience, are unsure about DIY, want expert assistance, or want to ensure proper handling and avoid potential issues.
Both DIY and professional options are readily available, ensuring that a dead key fob battery doesn’t have to be a major inconvenience. By understanding your choices, you can confidently decide where to change your key fob battery and get back on the road with a fully functional remote.
