Car Key Cutting Explained
Car key cutting is a lot more than just shaping a piece of metal. It is a complex procedure that ensures security, efficiency, and longevity of the keys.
It is not unusual to lose keys to your car, or have them break through the lock. To ensure that you are able to always drive your vehicle, you will require a replacement key cut.
Transponder Keys
If your car was manufactured within the last 20 years, it's likely to have transponder chips. These chips are small microchips in the key's handle that transmit signals to the car's onboard computer when you are using it. The computer onboard examines the serial number digitally of the chip prior to allowing the car to start. key cut near me open now prevents thieves from taking over your vehicle because they'd have to be aware of the unique serial number.
The microchip in your car keys transmits a low-level radio signal to the receiver inside the car. The radio signal activates the microchip, which transmits an encoded code to the car's onboard computer. The car will only start only if it recognizes the code. This stops "hot wiring" or other methods to steal cars.
Car keys with chips can be made at an authorized locksmith who offers these services. Some auto dealers like AutoZone sell them. Those stores carry a huge selection of keys and can help you get the right one for your vehicle. They can help you program the chip in your vehicle that is required to use the device.
You can also purchase laser cut keys that are more secure than conventional flat keys. They have the lock cylinder, which is more difficult to pick, and they are only duplicated using expensive laser key cutting equipment or specialized software. This type of technology is typically found in high-end vehicles but is now accessible on a variety of affordable models.
The VATS (vehicle-anti-theft system) key is a different kind of key that is difficult to duplicate. These keys have a black resistor in the key blade that is programmed with one of 15 potential values to prevent them from starting a vehicle that it's not intended to. These keys are expensive and require a key programming machine, which is only available through certain locksmiths.
VATS Keys
Before the days of transponder keys and automobiles equipped with computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a resistor pellet embedded inside it to confirm that the correct key is being used to start the car. 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 carbon block appropriately sized to have an exact electrical resistance.
GM used 15 different resistance values for the VATS pellets. They attached them to the key's blade to ensure that, when the key is turned in 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 starts to run. This isn't a way to make a car secure from theft, but it will delay the thief by at most 15 to 20 minutes.
Unfortunately, after a lot of use the VATS module in your car may begin to wear out. Every time a key is inserted into the ignition, it moves two tiny wires inside the ignition, and with time, the wires can start to break. When enough wires have been broken the signal goes out to the module and the car will not start.
You can solve this problem at home yourself by decoding your VATS key. It's not difficult to determine the resistance of a key by using a multimeter. You can find the resistance value by putting 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 check whether it works in your vehicle. Be sure to remove the key from the ignition prior to testing it, otherwise the new key may have an incorrect VATS value and may not work in your car.
Smart Key Fobs for Keys
Key fobs today are more than simply unlock and start the vehicle. They often have advanced features that many owners are unaware of. They can be employed as a security tool or a theft deterrent. They can remotely lock and unlock your doors, emit chirping sounds to help you find your car in a parking lot, or even allow you to call your vehicle by pressing the button on your smartphone. That's a lot more than you'd expect from the traditional keychain remote. However, all that additional functionality can mean that smart key fobs may be pricier to replace than standard keychain remotes. They also require programming by the dealer.
Some dealers charge up to $100 for one smart fob. This is a significant amount to pay for a device that is often time jostled around in purses and pockets where it is easily dropped, damaged or exposed to moisture and extreme temperatures. Fortunately, some automakers have developed ways to safeguard smart key fobs from the most common kinds of electronic attacks, such as relay attacks. These are often employed in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings by transmitting a fake signal from another nearby transmitter.
To protect a smart fob you can put it in a metal casing or use an RFID blocking case. This will block the transmission of these signals. The convenience of this technology is diminished if you need to take your key fob out every time you use it from the protective case.
Certain policies that are more recent like auto club memberships or 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 cloned at a locksmith or hardware retailer that provides key-fob cloning.
The decision of whether to buy an additional fob is dependent on the importance of your car's keyless entry and start functions. You should always keep an extra key or fob on hand in the event that you lose yours. If you do need to purchase a new replacement, Batteries Plus has a large selection of fobs to fit most cars and trucks. Plus, we offer an easy, fast service that is approximately 50% less than you'd spend at the dealership.
Traditional Keys
The traditional car key is made of a single piece of steel with a series grooves carved into it. These grooves are made to fit specific locks. These keys will open your locks and begin your vehicle, provided that you don't replace them with an electronic key or a remote key. The only drawback of using the traditional key is that it needs to be physically inserted into the ignition in order to start the vehicle. If your key from the past is lost, damaged or stolen, you'll need to visit an Gainesville locksmith to get new keys made from the blank.
There are a variety of choices to pick from based on how long it has been since you've were able to cut your keys. Certain keys utilize mechanical cutting machines to make copies, while others use laser-cut keys designed with enhanced security features in mind.
Some of these advanced features that come with modern keys include encryption and other security mechanisms. The encryption makes it difficult for thieves to duplicate keys or open locks. Transponder chips are a different anti-theft feature. They are embedded into the key and communicate with your vehicle. This means that it can only work only when you're within certain distance.
If you opt to use a traditional standard key, a locksmith could make a new one with a standard key cutting machine, which is available at most hardware stores. This is cheaper than using an electronic key fob or transponder key, and you'll be able to use your doors, locks and trunk.
You can also replace your traditional keys for your car with a laser cut version with a distinctive pattern. These keys were first introduced in the late 1990s, and are now a popular option for people who want to enhance the security of their vehicles. The majority of laser cut keys contain transponder chips that are designed to work only with your specific vehicle. If these chips aren't installed in your car it won't receive the signals coming from the key, and will not start.
