Key Fob Battery Replacement

When New Batteries Don't Work

You replaced the battery but your key fob still won’t work. This happens more often than you’d think. Modern key fobs lose their programming when power is interrupted, even for a few seconds.

The microchips inside don’t have capacitors to store memory like other electronics. When that battery comes out, your fob can forget how to talk to your car. Simply installing a new CR2032 or CR2025 won’t restore the connection.

We see this daily. Someone spends $10 on a battery and an hour trying to fix it themselves, only to discover they need professional reprogramming anyway.

Car Key Fob Programming

Programming That Actually Sticks

Each vehicle manufacturer uses different programming sequences. Honda fobs need a specific four-cycle process. Volkswagen systems require VCDS diagnostic tools. BMW and Mercedes need EEPROM services that most locksmiths can’t handle.

We have the manufacturer-specific equipment and training to program any key fob correctly. Our mobile vans carry the same diagnostic tools dealerships use, but we come to your location and charge a fraction of their prices.

When we program your fob, it stays programmed. No repeated button pressing hoping it will suddenly work.

Car Key Remote Fobs FAQs

Common questions about our Car Key Remote Fobs services

This is extremely common and usually means your fob lost its programming when the power was disconnected. Key fob microchips don’t have capacitors to maintain memory during battery changes, unlike other electronic devices. When you remove the battery, even briefly, the fob can forget its connection to your vehicle. The new battery provides power, but without proper reprogramming, the fob can’t communicate with your car’s receiver. Some vehicles are more prone to this than others, particularly Honda, Volkswagen, and European luxury brands.
Professional locksmith key fob repair typically costs $145-350 depending on your vehicle’s complexity, while dealerships can charge $2,500 or more for the same service. Dealerships often claim you need to replace the entire vehicle computer system when really you just need proper programming. We use the same diagnostic equipment dealerships use but charge a fraction of their prices. For luxury European vehicles requiring EEPROM services, our costs are still significantly lower than dealer alternatives while providing the same professional results.

First, check if the LED light flashes when you press any button. If there’s no light, the battery is likely dead or installed incorrectly. If the light works but your car doesn’t respond, the issue is probably lost programming or a faulty vehicle receiver. Don’t keep pressing buttons repeatedly – this can sometimes make programming issues worse. Contact us for proper diagnosis. We can quickly determine whether you need battery replacement, reprogramming, or fob replacement, saving you time and preventing further complications.
Key fob batteries generally last 1-5 years depending on usage frequency and storage conditions. If you use your fob multiple times daily, expect closer to 1-2 years. Extreme temperatures can also shorten battery life. Signs of a dying battery include reduced range (having to get closer to your vehicle), delayed response, or intermittent function. We recommend replacing batteries proactively rather than waiting for complete failure, especially if you only have one working fob. Our mobile service can replace batteries and test programming to ensure everything works properly.
