Dead Batteries
A dead battery is among the most common causes of key fob issues. Batteries can fail from long-term usage, exposure to harsh environmental conditions, or simply ageing. If a battery fails it will not supply the power needed to control the key fob and transmit the signal needed by the immobiliser system. This can prevent your car from starting and require a professional to repair the immobiliser system.

A good coin-style battery can be purchased at a local hardware shop or even at a general retailer for between $5-10. Once you've purchased a new battery, take the old one from the fob and carefully open the case. Look for an opening or notch along the edge that separates the bottom and top halves of the fob. Push the tip of a flathead screwdriver, coin or flathead screwdriver into the slot, and then work your way around the edges. Then, insert the new batteries and then snap the two halves together. When you're done recycling your old battery at a collection site near you.

This adds an extra layer of security, which reduces the possibility of thefts as well as other vehicular crimes.

The receiver might be too far away from the antenna. You can test this by connecting the receiver to another antenna. If the error message persists, you might need to replace the antenna or reroute the coaxial cable.
Antennas don't really go bad, but they can get twisted or pinched or even loosen from the connector, which may cause the RF levels to drop. You should also check whether there is any equipment between the antenna and the receiver, such as a surge protector or splitter since this can affect the signal strength.
