This adds a layer of security, reducing the risk of thefts and other vehicular crimes. Transponder keys, as with any other electronic device, are susceptible to various issues, including those relating to the chip's purpose.

Antennas do not really fail however they could be pinched or twisted, or even loosen from the connector, which could cause the RF levels to drop.
