It is a fact that most car owners don’t have the knowledge about car keys they are using. Different type of car keys have been around for a while to the point where they are no longer a luxury. Here is a look at those different types:

Smart Keys

Smart keys aren’t keys in the typical “mechanical” sense. Instead, they’re fobs that are either inserted in the dash or, in more advanced units, they stay in your purse or pocket. The driver turns the vehicle on and off with the press of a button mounted on the dashboard .

A smart key’s main security method is its ability to use rolling security codes. The car’s computer makes out the code given off by the smart key and verifies it before firing the engine up. Mercedes-Benz was one of the first automakers to use this technology, but just about every vehicle brand offers a smart key bundled in their high-tech packages.

Laser-Cut Keys

Laser-cut keys are typically referred to as sidewinder keys as a result of the shank’s distinctive cut. The machines required to cut such keys are a lot more expensive than your usual key-cutting machine and are less likely to be found at all locksmiths or hardware stores.

Laser-cut keys usually come with transponder chips and require programming by the dealer or a locksmith. All-in-one laser-cut keys are becoming increasingly popular, but  these keys are pricier and typically need to be replaced at the dealer.

Switchblade Keys

One advantage of the switchblade key is that its parts can be purchased individually. If for some reason your key is damaged and no longer works, you may buy the shank separately. But the more likely scenario for most people is that the entire key is lost, in which case you’ll need both the shank and the fob into which it folds.

Transponder Keys
