A locksmith can design a new basic key at a lower cost than what you pay at a dealership. You can also ask a neighbour or friend who knows how to program transponder keys aftermarket (which are less expensive than keys that are factory-made) to make you a spare key and then program it. It is important to have a spare key since modern cars won't start if the key does not have the correct chip.

Transponder keys resemble mechanical keys but have an electronic chip hidden inside the base. This chip is connected to the computer system in your vehicle. Your car will recognize the code contained in the chip and accept it, but it will refuse to start if another code is used.

If the spare key you have has chips, it will need to be programmed by a dealer. They'll require a special machine to both cut the key and then program it.

Transponder Keys


If your car was constructed in the past 10 years or so, you're likely to use a transponder key system. The keys contain a microchip within the key itself and an internal receiver in your car that both have been programmed to communicate with each other in order to start the vehicle.

Transponder keys can be an effective method of preventing theft since they require two parts to start a car - the transmitter inside the key and the receiver that is connected to the immobilizer. The car will not start without both the key and immobilizer system.

These key chips have an individual serial number specific to your vehicle. The serial number of the key is then sent to the immobilizer in the car and verified to be in line. If it does the engine starts, it will. The only thing that could defeat this security feature is a special device that can detect the chip and match it with another car.

Many people make the mistake of visiting a dealer to have their chip key copied, and end up paying more than they should.

Laser-Cut Keys

Laser-cut keys, also known as sidewinder keys due to their distinctive winding cuts in the key shank they add a layer of security to your vehicle. Keys like these are a great deterrent to auto theft because they require specialized equipment to duplicate.

They also have built-in chips that prevent the copying of keys by unauthorized people from starting your vehicle. They have a unique code that must be programmed into your car in order to unlock it and begin it. This extra layer of security will protect your investment and prevent thieves from attempting to steal your vehicle in exchange for parts or to sell it.

In terms of their design, laser-cut keys are slightly different from standard mechanical cut keys, as they have fewer carved-out grooves on the key. They also have a thicker key shaft that is an indication that it's not a regular car key. Locksmiths typically use milling machines to cut keys. This kind of tool looks like a drill and is designed to cut metal at very precise controlled angles.

These are some of the most secure keys you can get for your car, as they're extremely difficult to duplicate and only cut by a dealer or a certified locksmith. In contrast to traditional keys, they're made using a small piece of steel that is shaped into a code and then cut using the laser in the factory.

Smart Keys

In contrast to the traditional single piece of carved metal smart keys use RFID, also known as radio-frequency identification to connect with the car. They are equipped with a chip that has a unique code, which is encoded on every key. When you open your car's doors or open the trunk the key sends a signal to your vehicle's computer onboard. The computer will then prompt the appropriate frequency to allow you to start your vehicle.

The chip of the smart key has a number of security features that guard against theft. First, the key emits a very low-frequency signal which isn't received by any receiver but your car. If the computer onboard detects this signal, it will prompt another one that is an exclusive sequence that only your vehicle will recognize. This will stop a criminal with a high-tech background from using an external generator to "fool" the system and make the key work for other vehicles.

Some smart keys offer specific features, like saving preferences for drivers remote opening windows, opening the sunroof from afar and many more. This can be accomplished by activating the key's proximity sensor by pressing a button on the key or, in certain instances, by twisting a tiny metal part inside the key.

Some key fobs can be opened by holding the dead key in a slot, or by placing it near an inductive coil on the dashboard. Some even have an emergency (fully mechanical) key blade that is hidden inside the key to activate this.

Replacing a smart lock requires an appointment with a dealer, who can either purchase the replacement or have it on hand. The dealer will also need to program the new key so that it recognizes your car. You can also go to a locksmith for your replacement key fob to be programmed and then replaced. Locksmiths may charge more than the dealer, but they'll be able to complete the job faster and at a lower cost.
