Dead Batteries

A dead battery is one of the most frequently cited causes of key fob issues. The battery can degrade through long-term usage or exposure to harsh environmental conditions or simply ageing. When a battery fails to function, it is unable to transmit the signal required by the immobiliser to operate the key fob. This could stop your car from starting and require a professional to repair the immobiliser system.

When you're done, you can recycle your old battery at a collection facility near you.

If the new battery does not fix the problem it could be a problem with the RFID system on the key fob itself.

Faulty Transponder Key

This provides an additional layer of security, which reduces the risk of thefts and other vehicle-related crimes. Transponder keys, just like any electronic device, are prone to various issues that are related to the chip's function.

Transponder chips are delicate and even a small amount of physical damage can affect their ability to function. It's vital to inspect your transponder keys for signs of wear, as these can be the cause of an immobiliser malfunction.

In addition the internal microchip that is in a transponder key is also sensitive to water and other environmental conditions, which could affect its ability to communicate correctly with a vehicle's immobilizer system. It's therefore important to keep the key fob and the keychain as far away from water as possible.

Another reason the antenna may not be working is that the receiver is far from the antenna. You can test this by connecting the receiver to another antenna. If the error message is still present it is possible that you need to install an additional antenna or reroute your coaxial cable.


Antennas do not really fail however they may get bent or pinched, or they might come loose from the connector, which can cause the RF level to decrease.
