Keys Replacement For Cars

You can purchase an alternative key for a mechanical key at any hardware store. However, this key will have to be programmed by a locksmith or dealer.

Smart keys are more complex and require a visit to a car dealer to be paired with your car. They can be expensive however many car insurance companies will cover the cost.

Mechanical Keys

You can still purchase mechanical car keys, the ones that you put into an ignition lock cylinder to start your vehicle. If your car is equipped with one of these, it's cheap to replace the fob and key (if lost or stolen).

A locksmith can make the basic key for you at a less cost than what you'd buy from the dealership. You could also ask your neighbor or a friend who is proficient in programming transponder keys that are made for the aftermarket (which are cheaper than factory keys) cut keys and program them. It is important to have a spare key since modern cars won't start when the key does not have the proper chip.

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

If your spare key contains a chip, it will need to be programmed at a dealership. The dealership will require a special machine for both cutting and programming the key. These machines are only available through certain dealerships, and it's not likely that a locksmith will have the tools needed to make an engraved key using a laser transponder.

Keys with remotes are expensive to replace, especially in the event that you need a spare. You can try reprogramming your fob by yourself if you're missing the key shank and have a functioning replacement fob, but it could be time-consuming and laborious. You're better off contacting a dealer if you've lost both the fob and the key.

There are other types of car keys that require a more specific set of skills to replace, for example flip keys and smart keys. They are more complicated and usually have to be replaced at the dealership. Some key fobs have an electronic key that folds into the enclosure and opens doors or uses a proximity sensor to open and start your car.

Transponder Keys

Transponder keys will likely be found in cars that were built in the past 10 years. The keys contain a microchip in the key itself and a receiver in your car that are both programmed to communicate with one another to start the car.

Transponder keys are a great method to deter theft since they require two parts in order for the car to start - the transmitter (transponder) inside the key and the receiver connected to your immobilizer system. Without both the key and the immobilizer device present, the car will not start and it is not possible to connect hotwire.

These key chips have an individual serial number specific to your vehicle. When the key is inserted into your ignition, the serial number is sent to the cars immobilizer and checked to ensure that it is in line, it will then allow the engine to run. This security feature is only overcome by a specific device that reads the chip and match it with a different car.

You'll have to find a locksmith who has the tools to reprogram your key. Some car dealerships provide this service as well but they are typically more expensive than a independent locksmith because of their costs.

It can be difficult to get an entirely new key that has a chip. The key must first be cut using a particular machine to ensure that it has the correct tracks in place that can be used to program the key to your car. It requires specialized software as well as the appropriate key cutter to do the job correctly.

Some of the less complicated chip keys can be cloned at a variety of auto parts stores, but you need to know the serial number of the original key to ensure the correct information is encoded into the new key. Many people make the mistake of going to their dealer in search of an exact copy of a chip key only to end up paying inflated costs.

Laser-Cut Keys

Laser-cut keys are also referred as a sidewinder key due to the distinctive winding cut that is made on the shank of the key. They add an additional layer of security to your car. Keys like these are a great protection against auto theft since they require special equipment to duplicate.

Like transponder keys, they have built-in chips that block duplicate keys from opening your vehicle. They come with a unique code that must be programmed to your vehicle to unlock it and start it. This extra level of security will safeguard your investment and stop thieves from trying to steal your car for parts or to resell it.

In terms of their design, laser-cut keys are slightly different from standard mechanical cut keys due to having fewer carved-out grooves on the key. They also have a thicker key shaft which is an excellent indication that it's not your regular car key. Locksmiths typically use milling machines to cut keys. This tool is similar to a drill, and is designed to remove metal with precise angles.

They're among the most secure keys you can purchase for your car replacement key cost, as they're very hard to replicate and only cut by the dealer or a licensed locksmith. Unlike traditional keys, they're made from a small piece of steel that is shaped into a code and then cut using a laser in the factory. This type of key is very durable and can be able to withstand many years of wear and tear, making it one of the best options to protect your vehicle.

The key can be folded up into the fob, or it can pop out by pressing the button. Keys like this are typically used in German cars and offer an additional layer of security against car replacement key thieves. They also make it very difficult for a thief to pick or pick-lock your vehicle since the cylinder is extremely rugged and difficult to break into.

Smart Keys

Unlike the traditional single piece of carved metal, smart keys use RFID, also known as radio-frequency identification for short, to communicate with the car. This means they come with a tiny chip that contains an encrypted code that is unique to each key. The key transmits a message to the onboard computer in your vehicle each time you unlock the doors or open the trunk. The computer will then prompt the right frequency that allows you to start your car.

The chip of the smart key has several security features to protect it from theft. First, the key emits a low-frequency signal that can't be received by any other receiver, not even your vehicle. If the computer onboard detects this signal, it will display another one that is an exclusive sequence that only your vehicle can understand. This stops a tech-savvy criminal from using a pulse generator in order to "fool the system" and do the key work on other vehicles.

In addition to locking and starting the car, some smart keys also have additional functions like storing specific driver preferences remote opening windows or the sunroof, and more. These can be done by activating the key fob's proximity sensor, pressing a button on the key or, in some instances, by twisting a tiny metal piece inside the key.

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

Replace a smart key requires an appointment with a dealer, where they can purchase the replacement car keys near me or stock it. They'll also need to program the new key to recognize your car. However, you can also visit a locksmith to have your replacement key fob programed and replaced. A locksmith may charge more than a dealer, but they'll likely be able to complete the job quicker and for less.
