Online key fobs can look like a bargain next to dealer prices. Sometimes they work fine. Other times the fob can't be programmed to your car at all, and you've paid for something you can't use. Here's what decides which way it goes.
The fob has to be the exact right part
"Fits 2015 to 2019" in a listing isn't enough. Fobs for the same model can use different chips and different frequencies depending on the year, trim and where the car was sold. Look at the back of your original fob or inside the battery cover for the FCC ID and part number, and make sure the one you're buying matches both.
Used fobs are often locked to another car
Many fobs sold online are pulled from other vehicles. On a lot of makes, once a fob has been programmed to one car, it's locked to that car and can't be programmed to yours. A listing that says "new" may still be a used or refurbished fob. If the price looks too good, ask the seller if it has ever been programmed.
Cheap fobs can fail early
Low-cost aftermarket fobs vary a lot in quality. Common problems are weak range, buttons that wear out, and cases that crack. A fob that programs today and dies in three months isn't a deal.
The key blade still has to be cut
If your fob has a flip-out or emergency key, that blade comes blank and needs to be cut to your car. Push-to-start fobs usually have an emergency key inside that also needs cutting.
Check with us before you buy
The easiest way to avoid wasting money is to ask before you order. Text us the year, make and model, plus a screenshot of the listing showing the FCC ID and part number. We'll tell you whether it should work with your car.
