What Are the Car Key Types (And What to Do for a Replacement)?

Here Are Common Types of Car Keys with Details About Their Replacement:

The Traditional Key Is a Mechanical Car Key That’s Common for Older Car Models. It Doesn’t Have Specialized Encoding, So a Locksmith Can Easily Cut It with a Car Key Duplication Machine.

Many Car Keys Come with a Detachable Key Fob (Often Called Remote Head Keys.) This Key Fob Has an Internal Transmitter That Enables a Keyless Entry System, Like a Keyless Entry Remote or Remote Key.

3. Car Key Fob and Switchblade Key

The Newer Version of the Detachable Key Fob Is the Fob with a Switchblade Key. the Key Is Spring-Loaded in the Fob and Folds out When Triggered.

Transponder Keys Have a Plastic Head Embedded with a Computer Chip That Enables a Wireless Connection Between Your Key and the Car. Without This Connection, the Ignition Won’t Engage.

The Smart Key Allows for a Keyless Ignition System.

A Laser Cut Key (Sidewinder Key) Is a Distinct Key That Has a Thicker Shank Than a Traditional Key. It Has a Unique Pattern That Increases Your Vehicle’s Security but Makes It Harder to Duplicate. It Even Comes with a Transponder to Prevent Unauthorized Ignition.
