Other factors, such as interference from other devices operating on the same frequency, can also affect weak signals. Power lines and other key fobs wireless communication devices, and even cellular networks can interfere with the RF (radio frequency) signals that your key fob uses to connect to the receiver in your vehicle.

The most frequent cause for car keys not working is an inactive battery. These small devices rely on tiny lithium-ion coin or button cell batteries to function. They are easy to replace and are available at most pharmacies, food stores, and other places which sell electronic items. The fob's case can be opened using a screwdriver with a flat head, and gently pry out the battery that you have. Replace the battery, making sure it's not damaged, loose or damaged.

This means that the locksmith must use a special programming tool that is only available to the car manufacturer, which increases the cost.
