They are fairly affordable to replace in the event that they are lost, but they are less secure than modern alternatives.
In the early 1990s, automakers started using transponder keys that communicates with a sensor located on the car's ignition. They are more secure because the car must be within range of a sensor in order to start the engine. This type of key is also difficult to duplicate, as it has a distinct laser cut on both sides. Keys like this are often referred to as "flip key" or "transponder keys." Some automobile manufacturers also have the same type of key with a cylindrical design known as the Tibbe key which is harder to duplicate.

Key fobs utilize radio signals to communicate with the vehicle and carry out various functions. When a key fob is pressed it sends the coded signal to a receiver close to the lock system of the vehicle. The receiver interprets the code and then performs the requested action, such as unlocking the doors or launching the engine. Some key fobs also control other functions, for example, activating the car's panic alarm system, or disarming and arming the security system.
The radio frequency (RF), signals used by key fobs are like those that are used by cell phones. When the key fob is within range of a receiver, it transmits a small burst of energy, which energizes copper coils located on both sides of the device. These coils convert the RF energy into electricity, which powers a microcomputer chip inside the fob. The computer then sends a digitized version of your car's unique ID, which is verified by the receiver.
A lot of newer cars come with remote starter systems that allow the user to push a button on the fob to turn on the engine. In some instances, you'll have to insert a physical key into the ignition lock to start your vehicle. Most modern fobs come with small, metal keys designed to work if the RF system fails.

This can be fixed by spraying a dry, fluid into the cylinder (TeflonTM silicon, graphite or TeflonTM). Spray the lubricant into the cylinder, then turn the key several times in both directions. The lock should be free of any obstructions and can be turned with the key.

If the cylinder was destroyed in a burglary or accident, you may have to replace the entire car key assembly too.
