Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece metal. It is a sophisticated process that guarantees security, functionality, and longevity of the keys.

It is not unusual to lose your car key or even break it in the lock. You will need a new car key in order to ensure you can drive your vehicle at all times.

Transponder Keys

If your car was built in the last 20 years, it is likely to have a transponder chip. These microchips are situated in the key's handle and send a signal to the onboard computers of your vehicle when you use the key. The computer in the car reads the digital serial number within the chip and allows the car to start if it is the right one. This helps prevent theft of cars since thieves need to know your unique serial number to be able to steal it.

The microchip inside your car key transmits a low-level radio signal to the receiver inside the car. The radio signal activates the microchip, and it then sends an informational code to the car's onboard computer. The car will recognize this code and only allow it to start if the key is the correct one. This prevents "hot wiring" or other methods to steal cars.

Locksmiths who provide these services can design car keys with chips. Some car dealers, like AutoZone sell keys with chips. They have a vast selection of keys and can help you get the right one for your vehicle. They can help you program your car's chip which is needed for the device to function.

Laser cut keys are more secure than flat keys. They are more secure than flat keys because they have locks that are more difficult to pick. They can only be duplicated with expensive laser key cutting machines or with specialized software. This technology is most commonly found in luxury cars however, it is now available on a variety of affordable models.

The VATS (vehicle-anti-theft system) cheap key cutting is another type of key that is difficult to duplicate. These keys feature a black resistor in the key blade that is programmed with one of 15 possible values to stop the car from starting that it's not intended to. They are expensive and require a key programming machine, which is only available through certain locksmiths.

VATS Keys

Before the advent of transponder keys and automobiles equipped with computer chips that control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an internal resistor to verify that the correct key was used to start the car. The VATS pellet in black located in the middle of a VATS Key isn't a smart chip like those found on most modern keys. It is merely carbon or a block that is sized to have an electrical resistance value.

GM employed 15 different resistance values for the VATS pellets and attached the key's blade, so that when the key is turned in the ignition a coded signal will be sent to the module. If the signal matches the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine will start to run. This doesn't make a vehicle theft proof, but it will delay the thief by at least 15 to 20 minutes.

Unfortunately, after a long period of use the VATS module in your car may begin to wear out. The two wires that connect the ignition are moved every time a key is introduced. Over time the wires can begin to break. Once enough wires are broken the signal is lost to the module and the car won't start.

You can solve this issue at home by decoding your VATS key. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it is not that difficult. All you need to do is put one of the leads of your ohm meter on the metal prongs that are hanging out on both sides of the key. Then read the ohm meter's display to determine the resistance value of your key.

This is a great method to test out a new key and determine whether it works in your car. Remove the key from the ignition first before you test it. Otherwise the key may have an incorrect VATS and not function in your vehicle.

Smart Key Fobs

Certain automakers have devised methods to shield smart key fobs from common electronic attacks, like relay attacks. These are typically combined with a remote start hack that allows thieves access to your vehicle's settings through the transmission of a fake signal another transmitter near.

One method to safeguard the key fob's RFID is to keep it in a metal case or an RFID blocking case that prevents the transmission of these signals. However, having to remove the key fob from a case that is protected each time you need to use it undermines the convenience of the technology.

Fortunately, a few of the latest car insurance policies, auto club memberships, and extended warranty coverages will cover the cost of a replacement or pay for the loss of a fob. You can also save money on new car dealer charges and have your fob cut at the hardware store or locksmith who offers key fob cloning.

Depending on how much time has passed since the last time you cut your keys, there are several different alternatives to pick from when it comes to getting a new car key cut another copy. Certain keys utilize mechanical cutting machines to make copies, while others employ laser-cut keys that are specifically designed with enhanced security features in mind.

Modern keys come with advanced features such as encryption and anti-theft mechanisms. Encryption makes sure that only the right key is used to start your car which makes it harder for thieves to duplicate or pick locks.
