Some automakers offer instructions for do-it-yourself key fob programming online or in their owner's manuals. These steps can be tricky and you may need a second key fob to complete the procedure. It's wise for both tenants and owners to have two key fobs that function before they lose one.

If your car also has traditional metal keys it is possible to purchase one at an hardware or key cutting store, as long as the key was not lost in the fob. Fobs with transponders on both the key shank and the fob might need to be programmed by a professional, however this could be costly if you want to make more than one spare or if the key requires replacement.


Replacement fobs for German cars with a "flip" which is similar to the switchblade, are only available at the dealership. The reason for this is because the fobs are typically an exclusive transponder that can only be reset and reprogrammed by the manufacturer's dealer service department, which is usually the only manufacturer with the necessary equipment to do this.
