Car Key Cutting Explained

Cutting the car key is more than just bending a piece of metal. It is a complex process that ensures security, functionality and durability of keys.

It is not uncommon to lose your car keys or have them break in the lock. You will need a replacement car key to ensure that you can drive your car at all times.

Transponder Keys

Transponder chips will likely be fitted in vehicles built in the last 20 years. These microchips are tiny located in the handle of your key that send an electronic signal to the car's onboard computer whenever you use it. The computer in the car is able to verify the serial number of the chip before it allows the car key cutting service near me to begin. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to steal it.

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

Car keys with chips can be created at a locksmith that offers these services. Some car dealers, like AutoZone offer them. Those stores carry a huge variety of keys and can assist you in selecting the best one for your car. They can assist you in programming your car's chip which is needed to use the device.

Laser cut keys are more secure than flat keys. These keys are more secure than traditional flat keys because they have locks that are more difficult to pick. They are only duplicated with expensive laser key car cutting cutting machines, or specialized software. This type of technology is typically found in luxury vehicles, but it is now available in many affordable models of cars too.

Another type of car key that is hard to duplicate is the VATS (vehicle anti-theft system) key. These keys have a resistor that is black on the blade of the key. It can be programmed to one of fifteen possible values to stop it from starting a vehicle it's not designed to. These keys are more expensive to buy and require a special key cutting 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 a key with an embedded resistor to ensure that the correct key was used to start the car. The VATS pellet that is black in the middle of a VATS Key isn't a smart chip like those used on the majority of modern keys. It is simply carbon or a block that is sized to have an electrical resistance value.

GM employed 15 different resistances for VATS pellets and attached them to key blades in a way that, when the key was turned in the ignition a coded message is sent to the module. If the signal is in line with the one of the transistors in a VATS pellet then the relay in starter circuit will be activated and the engine will begin to run. This doesn't make a car burglar-proof, but it can delay the thief for a minimum of fifteen to twenty minutes.

After a prolonged period of usage the VATS module could start to wear out. Each time the key is inserted into the ignition it moves two very small wires within the ignition, and over time the wires could begin to break. When enough wires break then the signal to the module is not received and it will not start the car.

You can solve this problem at home yourself by decoding your VATS code. You'll need a multimeter and a chart to find out 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 is a great way to test a brand new key and see whether it works in your vehicle. Be sure to remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS value and not work in your vehicle.

Smart Key Fobs with Smart Keys

Key fobs today can do more than simply unlock and start the vehicle. They are also used as a security device and security measure against theft, with many of them having advanced features that the owners might not even know about. They can remotely lock and unlock your doors, emit chirping sounds to help you locate your vehicle in a parking lot, or even allow you to summon your vehicle by pressing the button on your smartphone. This is more than you'd imagine from a traditional keychain remote. Unfortunately, all that extra capabilities can mean that smart key fobs can be more expensive to replace than standard keychain remotes and they typically need to be programmed by the dealer.

In fact, some dealers charge up to $100 to replace one smart key fob. This is a significant amount to pay for a product that is often time snagging around in purses and pockets, where it can be easily damaged, dropped, or exposed to extreme moisture and temperatures. Fortunately, some automakers have developed ways to safeguard smart key fobs from common types of electronic threats like relay attacks. These are typically combined with remote start hacks which allows thieves to access your vehicle's settings via the transmission of a fake signal another transmitter nearby.

One method of protecting the smart key fob is to put it in a metal case or a dedicated RFID blocking case that prevents the transmission of these signals. The convenience of the technology is compromised if need to remove your key fob each time you use it from the case.

Some newer policies like auto club memberships as well as extended warranties, will cover the cost of replacing the fob or reimburse you if it's lost. You can also avoid paying dealership fees by having your fob copied at a locksmith or hardware store that offers key-fob-cloning.

For the majority of drivers, the decision to purchase a new key fob depends on how important your car's keyless entry and push-button start functions are. In any event it is advisable to keep an extra fob or key in case you lose it. Batteries Plus offers a large choice of replacement fobs that fit on most cars and trucks. In addition, our quick and efficient service is 50% less than the price you would pay at the dealership.

Traditional Keys

The car key of old is a single piece of metal with a series of grooves carved into it. These grooves are made to fit certain locks. These keys will unlock your locks and start the car, as long as you haven't changed them out for a smart key or remote key. The only disadvantage of using the traditional car key is that you have to physically insert it into the ignition to start the engine. If your double sided key cutting near me from the past is damaged, lost or stolen, you'll need to visit an Gainesville locksmith to have an alternative one cut from the blank.

You have a few options to choose from depending on how long it's been since you've had your keys cut. Certain keys employ mechanical cutting machines to produce copies, while others employ laser-cut keys made with security features in mind.

Some of these modern features that are included in modern keys include encryption and other security mechanisms. Encryption makes it harder for thieves to duplicate keys or open locks. Other security features that prevent theft include transponder chips that are incorporated into the key to connect with your car and make it only work when it's within a specific range of your car.

If you choose to use a conventional, standard key, a locksmith can make a new one using a standard key cutter machine which can be purchased at most hardware stores. This is less expensive than using a key fob or a transponder key, and you'll still be able to use your doors, locks and trunk.

Another option is to have your standard car key substituted with a laser-cut version that has a unique pattern. These keys were first introduced in the late 1990s, and are now a popular option for people who want to provide extra security to their automobiles. Typically, laser cut keys contain transponder chips that are programmed to work only for your specific vehicle. If the chips aren't present in your car it won't be able to respond to the signals coming from the key and won't start.
