Simply replacing the battery should restore power to the key fob and allow it to operate as usual, provided that the key fob was functioning correctly before the battery replacement. However, there are exceptions to this rule, particularly if the key fob loses power completely or if the battery replacement process involves disconnecting the battery for an extended period.
In such cases, the key fob may need to be reprogrammed to synchronize it with the vehicle’s security system and ensure proper operation.
