A key fob that does not work makes everything more inconvenient. You have to manually unlock the door every time. The remote start is gone. The panic button that makes you feel safer in a dark parking lot does not respond. And when the fob is completely lost or broken, you may not be able to get into your vehicle at all depending on the model.
Janesville Locksmith Service provides key fob programming and replacement throughout Janesville, WI and Rock County. We handle the diagnosis, sourcing, programming, and testing on-site, so you do not have to figure out how to get a non-working vehicle to a dealership.
What Key Fob Programming Involves
Key fob programming is not the same as key fob repair. When a fob is programmed, it is electronically paired to your specific vehicle so that the vehicle’s computer recognizes and responds to that fob’s signals.
A fob that has never been programmed, has been reset, or needs to be added to a vehicle after a replacement all require this programming step. Without it, the fob is essentially a blank device that will not communicate with your car.
Common Key Fob Problems We Handle
Drivers in Janesville call us about key fob issues that fall into a few common categories:
- The fob was replaced with an aftermarket unit but never programmed
- The vehicle’s battery was disconnected and the fob lost its pairing
- The fob was damaged by water or physical impact and stopped responding
- A replacement vehicle came with only one fob and the owner needs a second
- The fob works inconsistently and the issue is in the programming rather than the battery
Not every fob problem requires full replacement. We diagnose first and give you a clear picture of what the actual fix is before any work begins.
Key Fob Replacement vs. Reprogramming
If your existing fob is physically damaged beyond repair, replacement is necessary. If the fob hardware is intact but it has lost its programming or was never paired correctly, reprogramming resolves the issue without needing new hardware.
We carry fob replacement units for many common vehicle makes and models. When hardware replacement is needed, we source the appropriate fob and program it to your vehicle on-site.

- American brands including Ford, GM, Chevrolet, Dodge, and Chrysler vehicles

Frequently Asked Questions
Can you replace lost car key fobs? Yes. We can cut and program replacement fobs for many vehicle makes and models, including transponder and key fob systems.
Why is my key fob not working after I replaced the battery? A new battery is not always the issue. The fob may have lost its pairing to the vehicle, have internal damage, or need to be reprogrammed. We diagnose the root cause before recommending a solution.
Do you need my car to be running to program a fob? In most cases we need access to the vehicle and a working ignition source. We handle the specifics at your location and will let you know if anything unusual is required for your model.
How much does key fob programming cost? Pricing depends on the vehicle make and model and whether hardware replacement is needed. We provide upfront pricing before any work begins.
Can you program a fob I bought online? In many cases, yes. Not all aftermarket fobs are compatible with all vehicles, so results vary. Call us with the fob details and your vehicle information and we will advise you before you commit.
