In this primer on how to replace a car key fob, Consumer Reports says getting another high-tech key fob can be a pricey proposition.

Electronic keys introduce new components that can be expensive, even without paying a dealer to program them. If you can do the job yourself, you can save both time and money by not having to visit ...

Information about programming many manufacturers' key fobs is available on the Internet, although no one site acts as a central clearinghouse for all car models.

The dealer is telling me it’s $600 for a new key plus $250 for programming. I see key fobs online for around $20.

With many key fobs vulnerable to hacking, automotive security experts say car companies will soon require fingerprinting to start new vehicles.

First off, before paying for a new key fob, check your car’s basic warranty, insurance, or roadside assistance coverage to see if they cover lost or damaged keys.
