Replacement
We've all experienced keys for our cars disappearing into pockets on coats, behind couches or cushions, and in other places where they shouldn't. In the past keys were not a major issue and you could go to an auto locksmith or a dealer to obtain a new one. Today's cars, however, have complicated electronic fobs that do not just lock and start them, but also do cool things like open the windows, or summon the car from a parking space.
The fobs need the expertise of an auto locksmith to replace and program, so they're not inexpensive. We asked a few dealers to provide estimates on the cost to replace the fobs of some popular and high-end models. The quotes varied from $150 to $400.

The majority of modern vehicles come with fobs that have a transponder chip which needs to be programmed and require the assistance of an auto locksmith or dealer. The good thing is that the codes for these keys are usually kept on file at the dealer, which means that should you lose yours, they can probably replace it at minimal or no cost. Make sure to save the code number on a separate piece of paper and keep it in a safe location (and not in the vehicle) and you'll be good to go.
