They have an electronic microchip which sends an unique number to the immobilizer system of the car to verify the identity of the key. This adds a layer of security, which reduces the chance of thefts and other crimes committed by vehicles. Transponder keys, as with any electronic device, are prone to various issues, including those relating to the chip's purpose.

Antennas don't really go bad, but they can get pinched or twisted, or they might come loose from the connector, which could cause the RF level to decrease.

When you put the transponder chip inside your key, it transmits an encoded code to the car's immobiliser system which is then compared with the codes stored in the computer. If the codes are the identical, the engine will turn on and the immobiliser shuts off. If the immobiliser fails to recognize the signal, it'll stop the engine from turning and can leave you stuck in a secluded place.

There are a myriad of issues that could cause the car's immobiliser to cease working correctly, but the majority of them are fairly easy and affordable to fix.
