A car locksmith also has a set of keys that they specialize in dealing with. These types of keys are as follows:

Mechanically-cut Keys

These are simple metallic keys with not much security and are common in older car models. The cars that make use of these types of keys have a low level of security. People have to upgrade these keys with a security system installation.

Laser-cut Keys

This type is an upgrade to mechanically cut keys and varies only in the method of crafting the key. It uses a laser to give shape to the key. These keys are more secure than the former, even without the upgrades.

Smart Keys

This type of car key contains RFID sensors which are similar in concept to Near Field communication. The feature of smart keys is that it provides easy activation to the engine as well as the doors of the vehicle. You can get more out of these keys. However, it would also depend on the car’s make and model. Also, you need to be in the transmission range to engage with the lock system. All you need to do is push the start button of the key to start the ignition.
