Mechanical Keys

You can still purchase car keys that are solely mechanical, like the ones you insert into an ignition lock cylinder, and turn to start your car. If your car has one of these, replacing the fob and keys is fairly inexpensive (if they are lost or stolen).

A locksmith can design new keys for less than what you purchase from a dealership. You can also ask a neighbour or a friend who knows how to program transponder keys (which are less expensive than factory keys) to cut you a spare and program it. It is essential to have a spare because modern cars won't begin when a key that isn't programmed with the correct chip is used.

Transponder keys are like mechanical keys, but they have an electronic chip hidden in the base. This chip is connected to the computer system in your car. Your car will accept the code on the chip, but will not start if you try to use another code.

If the spare key you have has a chip that is programmed, it will have to be programmed at a dealership. They'll require an equipment that can cut the key and then program it.

Transponder keys can be an effective method of preventing theft since they require two components to start the car - the transmitter inside the key and the receiver attached to the immobilizer. The car will not start without the key and the immobilizer system.

These key chips have an unique serial number that is specific to your vehicle. When the key is inserted into the ignition the serial number is then sent to the immobilizer in the car and checked to ensure that it is in line the number, which allows the engine to start. This security feature is only blocked by a specially designed device that can read the chip and match it to another vehicle.

Many people make the mistake of visiting their dealer to purchase an exact copy of a chip key only to end up paying overpriced prices.

Laser-Cut Keys

Laser-cut keys, referred to as sidewinder keys due to their distinctive winding cuts in the key shank, add an extra layer of security to your vehicle. They are a fantastic deterrent to auto theft because they require specialized machinery to duplicate.

Like transponder keys, they feature embedded chips that stop duplicate keys from starting your car. They also usually contain a unique code the key that must be programmed to your specific vehicle to allow it to be opened and started. This additional level of security will safeguard your investment and prevent thieves from attempting to steal your vehicle in exchange for parts or to resell it.

They also have a thicker key shaft that is an indication that it's not a regular car key. Generally, locksmiths make use of a milling tool to cut these types of keys. This tool is similar to a drill, and it's designed to remove metal at precise angles.

They are the most secure keys you can purchase for your vehicle. They're hard to duplicate and must by cut by a certified locksmith or dealer. They're not made using traditional keys. Instead, they are made from a small piece steel that is shaped to a code at the factory, and then cut using a laser.

Smart Keys

Smart keys communicate with the vehicle via radio-frequency identification (RFID) instead of the traditional single piece of carved metal. This means they have a tiny chip that contains an encrypted code that is unique to each key. When you open your car's doors or open the trunk the key sends a signal to your car's onboard computer. The computer then triggers the right frequency which allows you to open your car and begin it.

The smart key's chip also has a number of security features that guard against theft. First the key emits a low-frequency signal that can't be picked up by any receiver but your car. If the onboard computer detects this signal, it will trigger an alternative one that's an exclusive sequence that only your vehicle can comprehend. This will stop a tech-savvy criminal from using an electronic pulse generator to "fool the system" and do the key work on other vehicles.


In addition to locking and starting the car, certain smart keys come with additional features such as storing specific preferences for drivers remotely opening windows, the sunroof, and many more. These can be done by activating the key's proximity sensor by pressing a button on the key itself, or, in some instances, twisting a small metal component inside the key.

Most key fobs feature a button that can unlock the doors on their own, but some have another method of opening them with a slot or by placing the dead key close to a spot on the dashboard, where it houses an inductive coil that can transfer energy. Some even include an emergency (fully mechanical) key blade concealed in the key to allow this.

Replacing a smart key typically requires a visit to the dealership, where they will either have the replacement in stock or make it available for you to purchase. The dealer will also need to program your new key so that it recognizes your car. You can also go to an locksmith to get your replacement key fob to be programmed and replaced. Locksmiths will cost more than dealers, but he or she can do the job quicker and cheaper.
