Car Key Cutting Explained

Car key cutting is more than just forming the metal. It is a complicated procedure that guarantees security, function and long-term use of keys.

It is not uncommon to lose your car key or even have it break in the lock. You'll require a replacement car key to ensure that you can drive your car at all times.

Transponder Keys

Transponder chips are likely to be fitted in vehicles built within the past 20 years. These microchips are situated in the handle of the key cutting cost and transmit a signal the onboard computers of your vehicle when you turn the key. The computer onboard is able to verify the serial number of the chip before allowing the car to begin. This prevents car theft since thieves need to know your unique serial number to be able to take over it.

The microchip inside your car key sends an unintentional radio signal to the car's receiver. The radio signal activates your microchip, which transmits a code to the onboard computer of the car. The car will recognize this code and only allow it to start only if the key is the right one. This stops "hot wiring" or other methods to steal cars.

Car keys with chips can be made by locksmiths that offer these services. Some car dealers, like AutoZone sell them. These stores have a wide variety of keys and can assist you in selecting the best one for your vehicle. They can assist you in programming your car's chip, which is required to operate the device.

Laser cut keys are more secure than flat keys. They have an cylinder for locking that is much more difficult to pick, and can only be duplicated using expensive laser key cutting equipment or specialized software. This technology is most commonly found in high-end vehicles but is now accessible in a wide range of low-cost models.

The VATS (vehicle-anti-theft system) key is a different type of key that's difficult to duplicate. The keys are black with a resistor in the key blade that is programmed with one of fifteen possible values to prevent them from starting a car that it's not meant to. These keys are more expensive to buy and require a specific key programming machine that can only be found at a few locksmiths.

Keys to VATS

Before transponder keys and cars with computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a pellet of resistance embedded within it to verify that the correct key is used to start the car. The VATS pellet in black located in the middle of a VATS Key is not an electronic chip that is like those found on most modern keys. It's just a block or carbon that is sized to have an electrical resistance.

GM employed 15 different resistance values for VATS pellets and attached them to the key's blade so that when the key is turned on in the ignition a coded signal will be sent to the module. If the signal matches the one of the transistors in a VATS pellet then the relay in the starter circuit will be activated and the engine will start to run. This isn't a way to make a car safe from theft, but it will delay the theft by at minimum 15 to 20 minutes.

After a long period of use the VATS module could begin to wear out. Each time a key is inserted into the ignition, it reroutes two small wires inside the ignition, and with time, the wires could begin to break. When enough wires have been broken the signal is lost to the module and the car won't start.

You can resolve this issue at home by decoding your VATS code. It's not difficult to determine the resistance value of a local key cutting with a multimeter. All you need to do is place one of the leads of your ohm meter onto the metal prongs that are visible on both sides of the key, then look at the display of the ohmmeter to find out the resistance value of your key.

This is also a great way to test the new key to determine whether it will work in your vehicle. Just be sure to remove the key from the ignition prior to testing it, or else the new key could be displaying an incorrect VATS value and not function in your car.

Smart Key Fobs for Keys

Key fobs today do more than simply unlock or start the car. They often have advanced features that a lot of owners are unaware of. They can be employed as a security tool or a theft deterrent. They can lock and unlock your door remotely, make chirping noises to aid in locating your car in a lot or summon it by pressing the button. This is a lot more than you could ever think of from a standard keychain remote. Unfortunately, all that extra features also means that smart key fobs can be pricier to replace than standard keychain remotes. They also require programming by the dealer.

Some dealers charge up to $100 for one smart fob. This is a significant amount to pay for something that spends a lot of its time in purses and pockets, where it is easily damaged, dropped or exposed to moisture and extreme temperatures. Certain automakers have developed strategies to protect smart keyfobs from common electronic threats, including relay attacks. They are usually paired with a remote start hack that allows thieves access to your vehicle's settings by the transmission of a fake signal from another transmitter nearby.

To safeguard a smart fob, you can store it in a metal case or even an RFID blocking case. This will block the transmission of these signals. However, having to remove the key fob from its case that is protected each time you want to use it undermines the convenience of the technology.

Fortunately, some of the newer car insurance policies, auto club memberships, and extended warranty insurance policies will pay for the cost of replacing a fob or pay for the loss of a fob. You can also save money on new-car dealership charges and get keys cut your fob cut at the hardware store or locksmith which offers key-fob cloning.

Traditional Keys

Traditional keys for cars are a single length of steel that has a series of grooves cut into it to fit in a specific lock. They can open your locks and begin your car, assuming you haven't replaced them with an electronic key cutting places or a remote key. The only drawback to using a traditional car key is that you must physically insert it into the ignition to start the engine. If your traditional car key has been lost or broken you'll need to visit a Gainesville Locksmith to have a new one made.

There are a variety of options to choose from depending on how long it's been since you cut your keys. Certain keys are cut using mechanical machines and others are laser-cut with enhanced security features.

Modern keys are equipped with advanced features such as encryption and anti-theft mechanisms. Encryption makes sure that only the correct key can be used to open your vehicle, making it more difficult for thieves to duplicate or pick locks. Other security features to prevent theft include transponder chips that are incorporated into the key to communicate with your car and make it only function when it's within a specific distance of your vehicle.

If you choose to use a traditional key, your locksmith can create an entirely new key using an ordinary cutter machine that is available from a variety of hardware stores. This is less expensive than a key fob, or a transponder. you will still be able to use your trunk locks, trunk locks and doors.

Another option is to have your standard car key replaced with a laser-cut version with a distinctive pattern. These keys first came out in the 1990s, and are now a popular option for those who wish to enhance the security of their vehicles. Laser cut keys are typically equipped with transponder chips programmed to work only with your vehicle. If these chips aren't present in your vehicle it will not respond to the signals transmitted by the key.
