Switchblade Key

The switchblade car key may sound like a bladed weapon to defend yourself in the parking lot, but it is actually a novel key that folds into the fob. This kind of key is available from a locksmith, auto dealer, or even online, but the cost will be more than traditional keys.

If the key fob is not damaged it is possible to replace the blade or shank. In addition, some of these types of keys may include VATS or PASS-Key circuit. These chips are equipped with resistors to prevent unauthorized use when placed in the ignition cylinder. They transmit different codes to the computer and to the immobilizer of the car. This will stop thieves from putting pressure on the ignition cylinder and also makes it harder for them to copy the key.

Transponder Key

If your car was manufactured in the last two decades, it's likely that it is equipped with a transponder. The chip on keys can help prevent theft by sending the car with a code when you insert it into the ignition.

This technology stops car theft by making hot-wiring useless.


If you have transponder keys you might observe that the grooves on the metallic portion of your key are starting to wear out. This is because the grooves shift tiny pins inside the lock to a position that allows your car to start up. You'll also notice that the key symbol on the dashboard of your car isn't visible 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 change your key.

Smart Key

A smart key takes technology one step further. Instead of using a standard key, this type of key has a computer chip that communicates with your car, allowing you to do standard tasks such as opening the trunk and door and even starting the engine at just the push of the button. These keys are more expensive than traditional keys or transponder ones due the technology integrated.

To work the smart keys work, they have to function, they have LF (low frequency) transmitting antennas both inside and outside of the vehicle. These antennas activate when you open the door or trunk handle. The LF signal travels through the doors and body to reach the interior electronics that recognize it as an authorized smart key. Once it is recognized, the car removes its immobilizer, and then starts the engine.

However, smart keys could also be a safety risk. How Stuff Works Electronics says that if you're too far from your car someone could be able to intercept the low frequency signal and begin your car by inserting it into a compatible ignition. Some manufacturers restrict the transmission range to 10cm to minimize the risk.

The year of manufacture and the type of vehicle you drive can affect the cost of a replacement key. As a rule, older models tend to have lower key replacements than newer ones. Some models might also require the use of a keyless system connected to the fob to allow features such as remote locking and trunk access.
