Car Key Fob Case Replacement Back in the day when keys were lost in cars, it meant a quick trip to your local hardware store or locksmith shop for an inexpensive replacement. But with modern cars relying on high-tech key fobs that control things such as power windows, replacing one is no longer pocket change. Some fob covers double as shields that stop signal hacking equipment thieves use to steal your ride. Battery If you have a key fob that doesn't unlock or start your car, the most common reason is an inactive battery. You can get new batteries at auto dealerships, locksmiths, and electronic stores.

The button pads on most key fobs can be a little sensitive and, if they are not protected by an enclosure, users could accidentally press them harder than intended. A good key fob case has an inner lining that either absorbs or reflects signals to alter transmission, which prevents accidental activation of the buttons.
