Different Types of Car Key Replacement

The most common car key types can be found in the following categories:

There are many different types of keys and fobs out there, and the type you have will determine how easy (or difficult) it is to replace it. For example, some key types are easy to duplicate at a hardware store or locksmith, while others need to be purchased at the dealership and programmed there.

A mechanical key has a traditional double-edged blade that inserts into the lock and turns to unlock. These are the most common and cheapest type to replace. However, they are not compatible with newer cars, which use a transponder chip inside the head of the key to start the car. These are much harder to replace without the original key, as they have to be electronically paired with the vehicle’s immobilizer system.

An electrical key has a small circuit board inside that controls the key functions, such as locking, unlocking, and starting. These are more complicated to replace than mechanical keys, and the costs can quickly add up if you need a replacement for a newer vehicle that uses this technology.

Depending on the model and year of your car, you may be able to buy a spare key online or at an auto parts store. The key will need to be the same make and model as your current one in order to work properly, so it is important to know the specifics of your vehicle before buying a replacement. Additionally, some keys need to be purchased at the dealership in order to be cut and programmed, so if you plan on buying your key from an online seller, you should call around to see if anyone nearby is willing to take care of this for you.

A laser-cut key has a unique cutting pattern that is used to identify the correct key blank and match it with the proper contours of your existing key. These are the most common on newer vehicles and can be expensive to purchase, since they must be bought from a dealer and programmed in order to work properly.

A smart key or FOB has a unique microchip in the plastic head of the key that communicates with the vehicle through an encrypted radio signal. This type of key can be expensive to replace if you do not have a working backup, as the replacement needs to be cloned in order to work correctly and is only compatible with the specific car it is for. Usually, this is only possible at a dealership, although some locksmiths may also be able to do it if you provide them with the appropriate proof of ownership documents. Ultimately, the easiest option for replacing a lost car key is to have a professional come and do it for you. They will likely be able to offer the best prices for a new key, and can even handle the programming if you do not have the existing chip with you.
