If you find yourself locked out, warm the fob with your breath or hands. Find out more tips to keep your key fob in top shape this winter.
Key Takeaways
- Store your Hyundai key fob in a coat's inner pocket to keep it warm and functional in cold weather.
- Use hand warmers alongside the fob for added heat during freezing temperatures.
- Regularly check the key fob battery and replace it every 3 to 5 years to prevent failures.

- Keep a spare key fob at home or with trusted friends for emergency access during winter lockouts.
Understanding How Cold Affects Your Key Fob
Cold weather can affect your Hyundai key fob. Low temperatures can cause battery issues, making it hard to lock or unlock your car.
Most key fobs use lithium batteries, which can underperform below 32°F (0°C). As it gets colder, the battery's chemical reactions slow down, leading to lower voltage and performance.
You may find your key fob working only occasionally or not at all in winter.
To help with this, keep a spare key fob in a warmer place, like your pocket. A key fob cover can also provide insulation.
Warming your fob before use can help it work better. Check the battery regularly and replace it before winter for reliable performance.
Signs Your Key Fob Is Freezing
If your key fob struggles in cold weather, it may be freezing. Look for these signs:
- Slow Response: If it takes longer to unlock your car, that's a warning sign.
- Remote Start Issues: If the remote start isn't working, check the fob.
- Reduced Range: You might need to stand closer to your vehicle for it to work.
- Stiff Buttons: If buttons feel hard to press or unresponsive, moisture may have frozen inside.
- Battery Drain: Cold can drain the battery quickly, causing failures.
If you notice these issues, your key fob may be freezing. Address it quickly to avoid being locked out of your vehicle.
Tips for Keeping Your Key Fob Warm

| Material | Pros | Cons |
|---|---|---|
| Silicone | Flexible, waterproof | Can attract dirt |
| Rubber | Shock-absorbent, durable | Can wear out over time |
| Leather | Stylish, protective | Expensive, less weatherproof |
| Hard Plastic | Lightweight, sturdy | Less grip, can crack |
| Neoprene | Insulating, soft | May not fit all fobs |
Pick a cover that suits your needs and keeps your key fob safe during winter.
Storing Your Key Fob in a Warm Place
Store your key fob in a warm place to avoid battery drain and malfunction in cold weather.
Extreme temperatures can shorten battery life or cause failure. Here are some tips:
Extreme temperatures can negatively impact your key fob's battery, leading to potential failure.
- Inside Your Home: Keep your key fob in a warm area, like a drawer or shelf, away from drafts.
- In Your Pocket: When outside, place your fob in an inner pocket of your coat to use your body heat.
- In a Heated Vehicle: If you must leave your fob in the car, store it in a heated space like the glove box.
Maintaining Your Key Fob Battery
Check your key fob battery regularly to avoid sudden failures. A Hyundai key fob typically uses a CR2032 battery, lasting 3 to 5 years based on usage.
Monitor the key fob's performance. If the range decreases or response delays, consider replacing the battery. Keep a backup battery for emergencies.
When replacing, select quality brands for reliability. You can buy CR2032 batteries at electronics stores or online.
Open the key fob carefully to avoid breaking clips. Note the old battery's orientation and install the new battery the same way.
Keep the key fob away from extreme temperatures and moisture, as they can drain the battery faster.
Regular checks help ensure smooth functioning.
