Signs Your Key Fob Battery is Dying
📡 Reduced Range
Your fob used to work from 30 feet away, but now you have to be right next to the car. This is a classic sign of a dying battery.
🔋 Intermittent Operation
The fob works sometimes but not others. You have to press buttons multiple times. This indicates low battery power.
🚗 Key Not Detected
Your vehicle displays "key not detected" or the push-button start won't work. Often caused by a dead battery in the fob.
🔑 No Response
The fob doesn't respond at all - no lights, no buttons work. This could be a dead battery or a more serious issue. We'll diagnose it.

Battery Replacement Questions
How long does battery replacement take?
Battery replacement takes 5-10 minutes. We open the fob, replace the battery, reassemble it, and test all functions. It's a quick while-you-wait service.
Can I replace the battery myself?
Yes, you can replace it yourself if you know how to open the fob. However, some fobs are tricky to open without damaging them, and you need the right battery type. We do it in 5-10 minutes with the correct battery and no risk of damage.
What if the battery doesn't fix it?
If replacing the battery doesn't solve the problem, we'll diagnose further. It could be a damaged fob, programming issue, or vehicle receiver problem. We'll identify the issue and recommend the best solution - whether that's fob repair, reprogramming, or a new fob.
How often do key fob batteries need replacement?
Key fob batteries typically last 2-5 years depending on usage. If you use your fob frequently (multiple times per day), the battery may need replacement sooner. Signs of a dying battery include reduced range and intermittent operation.
