Rainy weather can also alter the antenna of the fob, which results in a weaker radio signal. In some cases, even when the fob's location is close to the vehicle it might not respond to radio signals.

A corroded contact is an important reason for a key fob that is not responding to radio signals. A depleted battery may cause a fob to malfunction. If you replace the battery, but the issue persists, it is likely that the antenna is damaged. A professional locksmith can examine the key fob and make the necessary repairs.
