Car Key Cutting Explained

Car key cutting is a lot more than just shaping a piece of metal. It is a complex process that guarantees security, function and longevity of keys.

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

Transponder Keys

Transponder chips are likely to be fitted in vehicles built within the past 20 years. These chips are small microchips inside the key's handle that transmit a signal to the vehicle's onboard computer when you are using it. The computer on board scans the digital serial numbers in the chip and only allows the car to start if it's the correct one. This prevents thieves from taking over your vehicle since they'd need to be aware of the unique serial number.

The microchip in your car key sends an unintentional radio signal to the mobile car key cutting's receiver. This radio signal activates the microchip, which then transmits an informational code to the car's onboard computer. The car will only begin only if it recognizes the code. This stops "hot wiring" or other methods to steal cars.

Locksmiths who provide these services can design keys for cars that contain chips. Some auto dealers like AutoZone sell them. These stores offer a wide range of keys and can help you find the best one for your car. They can assist you in programming your vehicle's chip, which is required to operate the device.

Laser cut keys are more secure than flat keys. These keys feature a lock cylinder that is more difficult to pick, and can only be duplicated with expensive laser key cutting (your domain name) machines or specialized software. This type of technology is typically found in high-end cars, but it is now accessible in a wide range of low-cost cars as well.

Another kind of key for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor on the blade of the key that is programmed with one of 15 possible values to stop them from starting a car that it's not intended to. These keys are more expensive to buy and require a specific key programming machine that is only found at some locksmiths.

Keys to VATS

Before transponder keys and vehicles with computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key with a pellet of resistance embedded in it to confirm that the correct key is used to start the vehicle. The black VATS pellet in the center of the VATS key isn't an electronic chip like the ones used in modern smart keys. It is simply a piece of carbon properly sized to carry a specific electrical resistance value.

GM used 15 different resistance values for the VATS pellets and connected the key's blade, so that when the key is turned on the ignition the coded signal is transmitted to the module. If the signal is in line with 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 theft proof however it will delay the thief by at minimum 15 to 20 minutes.

After a lot of usage the VATS module may begin to wear out. The two wires inside the ignition are moved each time the key cutting places is placed. Over time the wires could begin to break. Once enough wires break, the signal to the module is not received and it will not start the car.

The good news is that you can solve this issue at home by decoding your VATS key. You'll require a multimeter as well as a chart to find out the resistance value of your key, but it is not difficult at all. All you have to do is put one of the leads of your ohm meter on the metal prongs that are hanging out on both sides of the key, and then look at the display of the ohmmeter to determine the resistance value of your key.

This method is also a good way to test a new key to see whether it will work in your vehicle. Remove the key from the ignition first before you test it. In the event that it is not removed the key could have an incorrect VATS and will not function in your vehicle.

Smart Key Fobs with Smart Keys

Key fobs today can do more than simply unlock and start the vehicle. Many of them have advanced features that a lot of owners are unaware of. They can be used as a security gadget or a theft deterrent. They can lock and unlock your door remotely, make chirping noises to assist you in finding your vehicle when you're in a hurry or call it up by pressing the button. This is a lot more features than you obtain from a traditional keychain remote.

It's a steep price for a device that's often tossed around in purses and pockets where it could be damaged, dropped, or exposed to extreme temperatures and humidity. Certain automakers have developed strategies to shield smart key fobs from common electronic attacks, like relay attacks. These are often used in combination with a remote-start hack that allows thieves to gain access to the settings of your vehicle by sending a fake signal from another nearby transmitter.

One way to protect a smart key fob is to put it in an aluminum case or a dedicated RFID blocking case that blocks the transmission of these signals. The convenience of this technology is compromised if you need to remove your key fob each time you need to use it from the case.

Fortunately, some of the newer car insurance policies, auto club memberships, and extended warranty insurance policies will cover the cost of a replacement or reimburse you for a lost fob. You can also save money on dealership charges and get a car key cut near me your fob cut at a hardware store or locksmith who offers key fob cloning.

Traditional Keys

They can unlock your locks and start the car, assuming you haven't changed them out to a smart or remote key. The only disadvantage of using the traditional car key is that you need to physically insert it into the ignition to start the engine. If your key from the past is lost, broken or stolen, you'll have to visit an Gainesville locksmith to have new keys cut from the blank.

Depending on how long has passed since the last time you got your keys cut There are many options to choose from when it comes time to get another copy made. Certain keys utilize mechanical cutting machines to make copies, while others use laser-cut keys that have been designed with enhanced security features in mind.

Some of these advanced features that come with modern keys include encryption and other anti-theft mechanisms. Encryption ensures that only the right key can be used to start your vehicle, making it more difficult for thieves to duplicate keys or pick locks. Transponder chips are another anti-theft feature. They are embedded into the key and communicate with your vehicle. This means that they only function only when you're within certain distance.

If you decide to use a conventional, standard key, a locksmith can create a new key with a standard key cutting machine that can be found at most hardware stores. This is less expensive than the key fob or transponder key, and you'll be able to use your doors, locks and trunk.
