Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece of metal. It is a complex process that ensures security, functionality and long-term use of keys.

It is not unusual to lose keys to your cheap car key cutting or even have them break into the lock. To ensure that you can always drive your vehicle, you will need a new key cut.

Transponder Keys

Transponder chips are likely to be added to cars that were that were built in the last 20 years. These chips are small microchips inside the key's handle that send signals to the car's onboard computer whenever you use it. The onboard computer detects the digital serial number in the chip and only 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 in order to have a chance at hijacking it.

The microchip inside the key transmits a low-level signal the receiver within the car. The radio signal activates your microchip which then transmits code to the onboard computer of the car. The car will only start if it recognizes this code. This prevents the use of "hot wiring" and other methods of theft of cars.

Car keys with chips can be made by an authorized locksmith who offers these services. They are also available at certain automotive stores, such as AutoZone. These stores have a large variety of keys, and can assist you in finding the appropriate one for your car. They can also help you programme the chip into your vehicle, which is essential for it to function.

You can also get laser cut keys, which are more secure than flat keys. They have the lock cylinder, which is much harder to pick, and they can only be duplicated using expensive laser key cutting equipment or specially designed software. This type of technology is typically found in high-end vehicles, however it is now available in a variety of affordable automobiles as well.

The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. The keys are black with a resistor on the key blade that is programmed with one of fifteen potential values to prevent the car from starting that it's not designed to. They are expensive and require an instrument for programming keys, which is only available at certain locksmiths.

Keys to VATS

Before the days of transponder keys as well as cars with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key with a pellet of resistance embedded inside it to confirm that the correct key is used to start the car. The black VATS pellet located in the middle of a VATS key is not a chip like those present in modern smart keys. It is simply a piece of carbon appropriately sized to have an exact electrical resistance.

GM employed 15 different resistance values for the VATS pellets. They connected the key's blade to ensure that, when the key is turned on the ignition the coded signal is sent to the module. If it 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 car secure from theft however it can delay the thief by at most 15 to 20 minutes.

After a prolonged period of usage the VATS module could start to wear out. The two small wires in the ignition move each time the key is introduced. As time passes the wires could begin to break. Once enough wires are broken the signal to the module is lost and it won't start the car.

The good news is that you can fix this problem yourself at home by decoding your VATS key. It's not difficult to determine the resistance value of a key by using the multimeter. All you have to do is put one of the leads of your ohm gauge on the prongs of metal that are hanging out on both sides of the key. Then look at the display of the ohmmeter to determine the resistance of your cheapest key cutting near me.

This is a great method to test out a new key and see whether it works in your car. Just be sure to remove the key from the ignition prior to testing it, or else the new key could have an incorrect VATS value and may not function in your car.

Smart Key Fobs

Certain automakers have devised methods to protect smart keyfobs from common electronic threats, including relay attacks. These are usually utilized in conjunction with remote-start hacks that allow thieves to gain access to your vehicle's settings through a fake signal from another nearby transmitter.

One method to safeguard the key fob's RFID is to store it in a metal case or an RFID blocking case that prevents the transmission of these signals. The convenience of the technology is compromised if have to remove your key fob each time you need to use it from the case.

Certain policies that are more recent, such as auto club memberships as well as extended warranties, will pay for a replacement fob or reimburse you if it's lost. You can also save money on new car dealer charges and have your fob cut at a hardware store or locksmith which offers key-fob cloning.

Traditional Keys

The car key of old is one piece of metal with a series grooves carved into it. These grooves are made to fit certain locks. These keys can open your locks and start your vehicle, provided that you don't replace them with a remote key or smart key cutter. The only drawback of using a traditional key is that it needs to be physically inserted into the ignition in order to start the car. If your car key is lost or broken you'll need to visit a Gainesville Locksmith to have a new one created.

Depending on how long has passed since you last got your keys cut There are many alternatives to select from when it comes to getting another copy. Certain keys employ mechanical cutting machines to create copies, whereas others use laser-cut keys that have been designed with enhanced security features in mind.

Some of these features that come with modern types of keys include encryption as well as other security 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 anti-theft features include transponder chips that are incorporated into the key to communicate with your car and make it only function when it's within a certain distance of your car.

If you opt to use a traditional key, your locksmith can design an entirely new key using the standard cutter machine, which can be purchased at most hardware stores. This is less expensive than a key fob or a transponder, and you are still able to operate your locks, trunk and doors.

Another option is to have the traditional car keys replaced with a laser-cut version that has a unique pattern. The first time these keys were introduced was in the 1990s, and they're a popular choice for people who want to add extra protection to their vehicles. The majority of laser cut keys contain transponder chips that are designed to work only with the specific vehicle you own. If these chips aren't present in your vehicle it won't receive the signals coming from the key and won't be able to start.
