For instance, wireless security systems and aftermarket LED lights can interfere with radio frequency signals. Try moving these devices to another location if you have them in your home.

In addition to devices using the same frequency, there are also environmental factors that could hinder the operation of a key fob. Metal objects, like a car can affect the signal strength. Weather conditions can also bend the antenna of the fob, which results in a weaker radio signal. In some instances, even when the fob is near to the vehicle, it may not respond to radio signals.

Check the battery to make sure your key fob's health. It should be in good condition, and the contacts should be free of corrosion. Contacts that are damaged by corrosion are the primary reason for key fobs not responding to the radio signals. A drained battery can cause the fob to malfunction. If you replace the battery but the problem persists, it's a good indication that the antenna is faulty. A professional locksmith can inspect the key fob and make necessary repairs.
