Mechanical Key

There's the possibility that you have a traditional mechanical key if the car was built prior to the '90s. These keys are simple and feature a head made of metal that is inserted into the ignition, then turned to start the car. They are easy to duplicate and don't contain electronic components. If you already have a traditional, non-electronic key an auto locksmith could easily cut the key and program it for less than $50.

In the 1990s, key fobs became popularized. They are designed to operate from a distance using a remote control instead of needing to insert the key into the ignition. They are much easier to duplicate and don't require any special tools to accomplish this although they will cost more than traditional keys.

Transponder keys were introduced in 1995 and are equipped with microchips that communicate with the vehicle's immobilizer to ensure that only the correct key is used to start the engine. Transponder keys are more difficult to duplicate, and cost more to cut and program.

If you're having trouble starting your car, it could be due to a faulty switch. This part will cost more than a standard one, however, it's worth the investment to ensure your vehicle is safe.

If your ignition lock cylinder is stuck or unable to be inserted into the ignition, gently move the key. This can aid in releasing the lock wafers that may have been slightly damaged by frequent use. This method isn't always successful and may cause further damage.

Remote Key

If your car is equipped with a traditional key and lock, you'll pay less for replacing it. These keys have a metal key shaft that's inserted into the ignition, and then turned to start your vehicle. They can be found at places like AutoZone and locksmiths, and don't require any special programming to work with your car.


If you're driving a brand newer car, your key could include a transponder chip within it to help prevent theft. These chips work by sending signals from the key to the receiver in the ignition. This ensures only a valid and working key can be inserted to start the engine. The most advanced versions of these keys are referred to as rolling keys, which send a different signal every time they're used so that even if someone does manage to take the key and then open your vehicle, it won't be capable of starting.

Key fobs are basically remote controls that allow you to unlock or lock your vehicle, as to set off the alarm or open the trunk, without having to insert it into the ignition. They are more prevalent on cars built after the 1990s. They're a great way to protect your car from theft, and give you more convenience.

You will have to pay more if you have to replace a keyfob because it requires additional programming. Most dealerships charge a fee for programming a new key fob however, you can save cash by following the owner's instructions to reprogram the key yourself. The key fob is priced between $50 and $100.

Switchblade Key

The switchblade key sounds like the bladed weapon used for self-defense in parking lots however it's really an innovative car key that folds into the fob when it is not being used. This type of key can be purchased at a locksmith shop, an auto dealer, or even online, but the cost will be higher than conventional keys.

Key fobs regulate the functions of your keys and will send a signal when they are within reach. The car's computer, or immobilizer will recognize the signal and allow the engine to start. G28 Car Keys are embedded in newer vehicles since 1995. They provide a unique, only-your-car read-code. Professional locksmiths can change the chip and key when they become damaged or lost.

Traditional keys can be replaced with inexpensive, basic fobs that have no integrated chip. You can usually find these at auto parts stores as well as other retail outlets for anywhere from $25 to $100. A replacement key fob with a chip in could cost up to $500, depending on the features and the manufacturer.

A key fob equipped with a switchblade costs between $200 to $300, which covers the cost of new batteries and programming. If the key fob is not damaged, you can replace the blade or shank. Some of these keys may also include a VATS-Key or PASS Key circuit. These chips have resistors that make it impossible for unauthorized use to be inserted in the ignition cylinder. They transmit different codes to the computer and to the immobilizer of the car. This deters thieves from attempting to take over your ignition cylinder and also makes it much more difficult for them to copy the key.

Transponder Key

Transponder keys are likely to be found on vehicles manufactured within the past 20 years. These keys transmit a code when they are inserted into the ignition. This can help prevent theft of your vehicle. The code is verified by your car's computer, and the engine will start when the code matches. Without a functioning transponder key it will be impossible to start your vehicle.

If you're considering buying an updated transponder key, you need to know that the car dealership will charge you a premium for the service. This is due to the fact that they're the only shop in town who can create the kind of key your vehicle requires. A locksmith can program and cut your new key at a fraction of the price.

Transponder keys were introduced as an extra measure of security in the 1980s, when car thieves began using a technique known as hot-wiring for vehicle theft. To combat this, General Motors started incorporating a small RFID chip into their key fobs that can communicate with your car's engine to start it. This technology prevents car theft since it renders hot-wiring useless.

You may notice that the grooves of your transponder key are beginning wear out. This is because the grooves shift tiny pins within the lock to a position that allows your car to start. You'll also notice that when you insert your key into the ignition the key symbol does not appear on the dashboard of your vehicle. If you are experiencing these problems, it is time to contact an auto locksmith in order to replace your keys.

Smart Key

Smart keys take technology to the next level. Instead of a traditional key, this type of key has an electronic chip that communicates with your vehicle, allowing you to perform standard tasks like opening the trunk and door and even starting the engine at the press of a button. These keys are more expensive than traditional keys or transponder ones due the integrated technology.

To work the smart keys, they are equipped with the LF (low frequency) transmitting antennas both inside and outside of the vehicle. They are activated when you open the door or trunk handle. The LF signal travels from the door and body to the inside electronics that determine that the smart key is valid. Once recognized, the car disables its immobilizer and starts the engine.

Smart keys can pose a safety risk. If you're too far away from your vehicle it is possible for someone to intercept the low-frequency signal and start your vehicle by simply placing it in a compatible ignition slot, according to How Stuff Works Electronics. Certain manufacturers restrict the range of transmission to 10 centimeters to limit this risk.

The model year and type of vehicle you drive influence the cost of a replacement key. In general, older vehicles have lower replacement keys than modern models. Some models might also require the use of a keyless system connected to the fob in order to provide features such as remote locking and trunk access.
