Key fobs became popular in the 1990s and are designed to operate by remote controls, rather than being placed into the ignition. They are much easier to duplicate and don't require any special tools to do so however they cost more than traditional keys.

Transponder keys were introduced in 1995 and are fitted with an electronic chip that communicates with the immobilizer on the vehicle to ensure that only the appropriate key is used to start the engine. Transponder keys can be difficult to duplicate, and cost more to cut and program.

Remote Key

If your car has traditional keys that is a traditional key, you will spend less money to replace it. The keys are made of a metal shaft that is inserted into the vehicle's ignition and then turned to begin it.

If you're driving a newer car, your key could have a transponder chip in it to help in preventing theft. The chips transmit an electronic signal from the key to a device in the ignition to ensure that only a genuine key is used and able to start your engine. The more sophisticated versions of these keys are called rolling keys, which transmit a different signal every time they're used so that even if someone does manage to get the key and enter your vehicle, it won't be capable of starting.

Key fobs are basically a remote control that allows you to lock or unlock your car, as well being able to activate the alarm or open the trunk without having to physically insert it into the ignition. They are more prevalent for vehicles manufactured after the 1990s. They're an excellent way to protect your car from theft, and give you more convenience.

The majority of dealers will charge a fee to program the new key fob, however you can save money by following the instructions in your owner's manual that describe specific sequences of turns and button presses to program it yourself. The key fob itself can cost between $50 to $100 or more.

Switchblade Key

The switchblade key sounded like a bladed weapon to defend yourself in the parking lot however it's really an innovative car key that folds up into the fob when it is not in use. This type of key is available from locksmiths, an auto dealer, or on the internet however it will cost more than traditional keys.

Key fobs regulate the functions of your keys and send signals when they are within range. The computer or immobilizer in the car will detect the signal, and allow the engine start. Transponder chips are integrated into modern vehicles since 1995. They provide a unique, only-your-car read-code. Professional locksmiths can modify your key and chip if they become damaged or lost.

Simple, inexpensive fobs without an integrated chip can be used to replace traditional keys. They are usually available at auto parts stores as well as other retail outlets for $25 to $100. The cost of a replacement key fob that has a built-in chip can range from $500 or more, based on the manufacturer and features included.

A key fob with the switchblade could cost between $200 to $300, which includes the price of a new battery and programming. The parts can typically be purchased separately, meaning that when the key fob isn't harmed you can just replace the blade and shank. Additionally to that, certain kinds of keys can include VATS or PASS-Key circuit. These chips have resistors that prevent unauthorized use when inserted in the ignition cylinder. They transmit various codes to the computer and immobilizer of the vehicle. This prevents thieves from attempting to force your ignition cylinder and also makes it more difficult for them to copy the key.

Transponder Key

If your car was built in the last two decades, it's likely that it has a transponder key. The keys transmit a code when they are inserted into the ignition. This helps prevent the theft of your vehicle. The car's computer is able to check the code and start the engine when it matches. Without a working transponder key it will be impossible to start your car.

You should be aware that a car dealership will charge you a fee if you want to get an updated transponder. They are often the only people in town who can make the exact type of key your vehicle requires. Locksmiths, on the other hand, can cut and program your new key for less than the cost.

Transponder keys are a security measure that came into play when car thieves began using a technology known as hot-wiring for stealing vehicles in the 80s. To stop this, General Motors started incorporating a small RFID chip into their key fobs, which can communicate with your car to initiate it. This technology prevents car theft by rendering hot-wiring ineffective.





If you own transponder keys, you may observe that the grooves on the metallic portion of your key are starting to wear down. The grooves inside the lock are able to move the pins into a position that allows your car can start. You'll also be able to see that the key symbol on your dashboard doesn't appear when you insert the key into the ignition. If you're experiencing issues like this it's time to contact an auto locksmith professional to replace your key.

Smart Key

Smart keys take technology to the next level. Instead of a traditional key, this type of key has a computer chip that communicates with your car, allowing you perform standard tasks like unlocking the trunk and door and even starting the engine at just the push of a button. Although they are convenient they are an additional cost than transponder keys or traditional keys because of the integrated technology.

To work the smart keys, they are equipped with LF (low frequency) transmitting antennas both inside and outside the vehicle that activate when you open the trunk or door. The LF signal travels between the body and door to the interior electronics which identify the smart key as valid. Once the smart key is identified, the vehicle shuts off the immobilizer, and then starts its engine.

But smart keys can also pose a security risk. If you're too far away from your car, someone could detect the low-frequency signal and start your vehicle by placing it in an ignition slot, as per How Stuff Works Electronics. Certain manufacturers restrict the transmission range to 10 centimeters to limit the risk.

The type of vehicle you drive and the model year can affect the cost of replacement keys. As a rule older cars tend to have more expensive replacement keys than those with more modern features. Also, some models may require an entry system that's keyless and integrated with the fob to enable features such as remote locking and trunk opening.
