Car Key Cutting Explained

Car key cutting is much more than just forming an object of metal. It is a complex process that guarantees security, function and durability of keys.

It is not uncommon to lose keys to your car or even have them break into the lock. You'll need a new car key in order to ensure you can drive your car at all times.

Transponder Keys

Transponder chips are likely be installed in cars built in the last 20 years. These microchips are in the handle of the key and transmit a signal the onboard computers in your vehicle when you press the key. The computer in the car reads the digital serial number inside the chip and allows the car to start if it is the correct one. This prevents thieves from hijacking your vehicle because they'd have to be aware of the unique serial number.

The microchip in the key sends a low-level signal the car's receiver. This radio signal activates the microchip that then transmits the code to the onboard computer of the car. The car will only begin when it recognizes the code. This stops "hot wiring" or other methods to steal cars.

Locksmiths who offer these services can design keys for cars with chips. Some car dealers, like AutoZone sell keys with chips. Those stores carry a huge variety of keys and can assist you in choosing the appropriate one for your vehicle. They can help you program your car's chip which is needed to operate the device.

You can also get laser cut keys, which are more secure than conventional flat keys. These keys feature a lock cylinder that is more difficult to pick, and they can only be duplicated with expensive laser key cutting machines or specialized software. This technology is more prevalent in luxury vehicles, but it is now accessible in a variety of affordable automobiles as well.

The VATS (vehicle-anti-theft system) key is a different type of key that's difficult to duplicate. They contain a resistor that's black on the blade of the key. It can be programmed to any of fifteen possible values to stop it from starting a car that's not designed to. These keys are expensive and require an instrument for programming keys, which is only available at a few locksmiths.

VATS Keys

Before transponder keys or cars with computers built-in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a resistor pellet embedded within it to verify that the correct key is used to start the vehicle. The black VATS pellet in the center of a VATS key is not an electronic chip like the ones found on modern smart keys. It is simply a carbon block appropriately sized to have an electrical resistance that is specific to.

GM employed 15 different resistances for the VATS Pellets and attached the key blades to them so that, when the key was turned in the ignition a coded signal is sent to 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 does not make a car secure from burglary, but it can delay thieves for at least 15 to twenty minutes.

Unfortunately, after a long period of usage, the VATS module in your car could start to wear out. Every time a key is inserted into the ignition it moves two tiny wires within the ignition, and, over time, the wires may begin to break. Once enough of the wires break, the signal to the module gets lost and it won't start the car.

The good news is that you can fix this problem yourself at home by decoding your own VATS key. You'll require a multimeter and a chart to find out the resistance value of your van key cutting, but it is not difficult at all. You can find the resistance value by putting one of the leads on the prongs made of metal on both sides of your key.

This is also a great way to test the new key to determine whether it will work in your car. Remove the key from the ignition first before you test it. In the event that it is not removed, the key may have an incorrect VATS and not work in your vehicle.

Smart Key Fobs for Keys

van key cutting fobs today can do more than simply unlock and start the car. They are also used as a security device and burglar deterrent, with a lot of them featuring advanced features that owners might not even be aware of.

Fortunately certain automakers have come up with methods to shield smart key fobs from the most common kinds of electronic attacks, such as relay attacks. These are often combined with a remote start hack which allows thieves to access your vehicle's settings through the transmission of a fake signal from another transmitter nearby.

One method of protecting the key fob's RFID is to store it in a metal case or an RFID blocking case that blocks the transmission of these signals. The convenience of the technology is compromised if you must remove your key fob every time you want to use it from the protective case.

Some newer policies, such as auto club memberships and extended warranties can pay for a replacement fob or reimburse you in the event that it is lost. You can also avoid paying new-car dealership fees by having your fob cloned by a locksmith or hardware store that offers key-fob-cloning.

The decision to purchase a new fob is largely dependent on the importance of your car's keyless start and entry functions. It is always advisable to keep an extra key or fob on hand in case you lose yours. Batteries Plus offers a large choice of replacement fobs that fit in most vehicles and trucks.

Traditional Keys

Modern keys have advanced features such as encryption and anti-theft mechanisms. Encryption makes sure that only the correct key is used to start your car making it much more difficult for thieves to duplicate or pick locks. Other security features to prevent theft include transponder chips that are embedded in the key to communicate with your car and make it only work when it's within the range of your car.
