Car Key Cutting Explained

Car key cutting is much more than just forming the metal. It is a sophisticated procedure that ensures security, efficiency and the longevity of keys.

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

Transponder Keys

Transponder chips are likely to be added to cars that were that were built in the last 20 years. These microchips are tiny located in the key's handle which transmit signals to the car's onboard computer when you use it. The computer in the car reads the digital serial number in the chip and only allows the car key cutting near me prices to start if it's the right one. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to take over it.

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

Locksmiths who offer these services can create car keys with chips. Some auto dealers like AutoZone offer keys with chips. These stores offer a wide selection of keys, and can help you find the appropriate one for your car. They can assist you in programming your vehicle's chip which is needed to use the device.

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

VATS Keys

Before the days of transponder keys and automobiles with built-in computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an embedded resistor to ensure that the correct key was used to start the car. The black VATS pellet inside the middle of a VATS key is not an electronic chip as found on modern smart getting keys cut, it's simply a piece of carbon properly sized to carry an exact electrical resistance.

GM used 15 different resistances for the VATS Pellets. They connected the key blades to them so that when the key is turned on, 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 a thief for at least 15 to 20 minutes.

After a lot of usage, the VATS module can begin to wear out. The two wires that connect the ignition are moved each time a key is placed. As time passes the wires could start to break. Once enough of the wires are broken then the signal to the module gets not received and it will not start the car.

The good news is that you can fix this issue yourself by decoding your VATS key. You'll need a multimeter and an indicator chart to determine the resistance value of your key, but it's not difficult at all. You can determine the resistance value by placing one of the leads on the prongs of metal on both sides of your key.

This method is also a good way to test a new key to determine whether it works in your car. Be sure to remove the key from the ignition prior to testing it, as the new key may have an incorrect VATS value and may not work in your car.

These are typically combined with a remote start hack that allows thieves access to your vehicle's settings via the transmission of a fake signal by another transmitter nearby.

To safeguard a smart fob you can put it in a metal casing or even an RFID blocking case. This will block the transmission of these signals. However, the necessity of removing the key fob from a case that is protected each time you use it is not a good way to enjoy the benefits of the technology.

Fortunately, a few of the latest car insurance policies such as auto club memberships and extended warranty insurance policies will cover the cost of a replacement or pay for the loss of a fob. You can also save money on new-car dealership charges and get your fob cut at a hardware store or locksmith that offers key-fob cloning services.

The decision to buy a new fob is dependent on the importance of your car's keyless entry and start functions. Always keep a spare key cutting cost or fob on hand in the event that you misplace yours. Batteries Plus offers a large range of replacement fobs that will fit most cars and trucks. Additionally, our fast and easy service is about 50% less than the price you'd buy from a dealership.

Traditional Keys

There are several options to choose from depending on how long it has been since you've cut your keys. Certain keys are cut with mechanical machines, while others are laser-cut with added security features.

Modern keys have advanced features, such as encryption and anti-theft mechanisms. The encryption ensures that only the correct key is used to open your vehicle making it much more difficult for thieves to duplicate keys or pick locks. Transponder chips are a different anti-theft feature. They are embedded into the key and communicate with your vehicle. This makes it only work when you're within a certain distance.
