They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an enormous success in preventing car theft.

Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it will send an electrical signal that is received by a hidden antenna around the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip within the key. The computer onboard of the car will then recognize the key as valid and will allow fuel flow and power the starter to begin the engine.

However, locksmiths for automotive advise against using them since they are likely to work poorly or even not at all.

This will save you money in the long run by avoiding expensive repairs or replacing the fobs.
