Car Key Cutting Explained

Car key cutting is a lot more than simply shaping an object of metal. It is a sophisticated procedure that ensures security, functionality, and longevity of the keys.

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

Transponder Keys

If your car was constructed in the past 20 years, it is likely that it has transponder chips. These microchips are situated in the handle of the key and transmit a signal your vehicle's onboard computers when you use the key. The computer on board detects the digital serial number inside the chip and allows the car to start if it is the correct one. This prevents car theft since thieves need to know your unique serial number to be able to steal it.

The microchip inside your car keys cut and programmed key sends an unintentional radio signal to the receiver inside the car. The radio signal activates your microchip which then transmits code to the computer onboard of the car. The car will only start if it recognizes this code. This stops "hot wiring" or other methods to steal cars.

Locksmiths who provide these services can create keys for cars with chips. Some auto dealers like AutoZone offer keys with chips. These stores offer a wide range of keys and can assist you in choosing the right one for your car. They can also help you program the chip to your vehicle, which is required to use it.

You can also purchase laser cut keys, which are more secure than flat keys. These keys feature the lock cylinder, which is more difficult to pick, and are only duplicated using expensive laser van key cutting cutting machines or with special software. This technology is more common in high-end vehicles, however it is now available in a wide range of low-cost automobiles as well.

The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. They come with a resistor black on the blade of the key. It can be programmed with one of 15 possible values to prevent it from starting getting a new car key cut vehicle it's not designed to. These keys are costly and require the use of a key programming machine which is only available at certain locksmiths.

Keys to VATS

Before the days of transponder keys and automobiles equipped with computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a resistor pellet embedded in it to confirm that the correct key is being 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 block of carbon that is sized appropriately to have an electrical resistance that is specific to.

GM employed 15 different resistance values for the VATS pellets and connected them to the key's blade to ensure that, when the key is turned on in the ignition, a coded signal is sent to the module. If the signal is in line with the signal of the transistor in a VATS pellet, then the relay in the starter circuit will turn on and the engine will begin to run. This doesn't make a car secure from theft however it will delay the thief by at minimum 15 to 20 minutes.

Unfortunately, after a lot of use, the VATS module in your car may start to wear out. Each time a key is inserted into the ignition it reroutes two small wires inside the ignition and, over time, the wires could begin to break. Once enough wires are broken, the signal is lost to the module and the car won't start.

You can resolve this issue at home yourself by decoding your VATS key. It's not hard to determine the resistance value of a key with a multimeter. You can find the resistance value by placing one of the leads on the metal prongs on both sides of your key.

This is a great opportunity to test a brand new key and see if it works in your vehicle. Make sure you remove the key from the ignition before you begin testing it, as the new key may have an incorrect VATS value and not function in your car key cut.

Smart Key Fobs with Smart Keys

Key fobs of today are more than just a way to unlock or start a car. They also function as used as a security device and burglar deterrent, with a lot of them incorporating advanced features that the owners might not even know about. They can lock and unlock your door from a distance, make chirping noises to aid in locating your car in a lot or summon it by pressing a button. This is more than you'd imagine from a traditional keychain remote. Smart key fobs are more expensive to replace because of their additional functions. They also require to be programmed by the dealer.

In fact, some retailers will cost upwards of $100 to replace one smart key fob. It's a high price for a product that is frequently tossed around in pockets and purses where it can be damaged, dropped or exposed to extreme temperatures and humidity. Some automakers have developed methods to protect smart keyfobs from common electronic attacks, like relay attacks. They are usually paired with remote start hacks that allows thieves access to your vehicle's settings via the transmission of a fake signal another transmitter nearby.

One method of protecting a smart key fob is to keep it in a metal case or use a dedicated RFID blocking case that blocks the transmission of these signals. However, having to take the key fob from its protective case every time you want to make use of it is a hassle and a detriment to the efficiency of the technology.

Some of the newer policies such as auto club memberships as well as extended warranties will pay for an additional fob, or reimburse you if it gets lost. You can also avoid paying dealership fees by having your fob cloned at a hardware or locksmith store that offers key-fob-cloning.

Traditional Keys

The car key of old is one piece of metal with a series of grooves carved into it. These grooves are made to fit certain locks. These keys can open your locks and start the car, assuming you haven't changed them out to a smart or remote key. The only downside of using an old-fashioned car key is that you have to physically insert it into the ignition to start the engine. If your traditional car key is lost or broken, you will need to visit the Gainesville Locksmith to have a new one created.

You have a few choices to pick from based on how long it's been since you cut your keys. Some keys use mechanical cutting machines to create copies, while others use laser-cut keys that are designed with enhanced security features in mind.

Some of these features that come with the modern-day keys include encryption and other anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or take locks. Other security features that prevent theft include transponder chips, which are embedded in the key to communicate with your car and make it only work when it's within the distance of your vehicle.

If you decide to use a traditional standard key, a locksmith could make a new one with a standard key cutting machine, which is available at many hardware stores. This is cheaper than a key fob or transponder, and you can still operate your trunk, locks and doors.

Another alternative is to have your standard car key substituted with a laser-cut version that has a unique pattern. These keys first came out in the 1990s, and they're a popular choice for those who wish to provide extra security to their automobiles. Laser cut keys typically have special transponder chips that are designed to work only with your specific vehicle. If these chips aren't installed in your car it won't be able to respond to the signals coming from the key and won't start.
