Replacement remote key fobs for Honda vehicles can be purchased from a dealership or online from websites such as keyless-remotes.com. Factory branded key fobs purchased from Honda dealers cost more but can be programmed by a Honda technician at the time of purchase. Key fobs bought online, however, can be programmed by the vehicle owner.

Repeat this process two additional times.
Turn the key in the ignition to the "on" position. Press and hold the "lock" or "unlock" button on the remote for one second and wait for the door locks to lock and unlock automatically.
