This provides an additional layer of security, decreasing the possibility of thefts as well as other crimes committed by vehicles. But, like other electronic device transponder keys are prone to a variety of problems that are related to the chip's functionality.

In addition the internal microchip that is in the transponder key is sensitive to environmental and water conditions, which may hinder its ability to communicate with a vehicle's immobilizer system. It's therefore important to keep the key fob and the keychain as far from water as possible.
It is important to keep in mind that a transponder car key is designed specifically for a particular vehicle.

Receivers or Antennas that are not working properly

Antennas aren't necessarily bad, but can be bent, pinched or detached from their connectors, which can cause the RF strength of the signal to decrease. Also, you should check if there is any equipment between the antenna and the receiver, for instance a surge protector or splitter, as this may influence the signal strength.
If the EEPROM programming method is employed to program a new car key, it will require the removal of specific modules from your vehicle (security components) and then reading the "password" and other stored data from them. This requires a great deal of expertise, since there is a risk that the data may be corrupted.
