5 Lessons You Can Learn From Cut Car Key Car Key Cutting Explained Car key cutting is more than just shaping an object of metal. It is a complex process that guarantees security, functionality and the longevity of keys. It is not unusual to lose your car keys or have them break through the lock. You will need a new car key in order to ensure that you are able to drive your vehicle at all times. Transponder Keys If your car was constructed within the past 20 years, it is likely to have a transponder chip. These microchips are located in the handle of the key and transmit a signal to the onboard computers of your vehicle when you turn the key. The computer in the car checks the serial number digitally of the chip prior to allowing the car to start. This stops theft of vehicles, as thieves would need to know your unique serial number to be able to take over it. The microchip in your car keys transmits an unintentional radio signal to the car's receiver. This radio signal activates the microchip, which transmits an informational code to the car's onboard computer. The car will be able to recognize this code and will only allow it to start only if the key is the right one. This will stop "hot wiring" or other methods of stealing cars. Car keys with chips can be made at an authorized locksmith who offers these services. They can also be purchased at certain automotive stores like AutoZone. These stores have a wide range of keys and will assist you in selecting the best one for your vehicle. They can also help you programme the chip into your vehicle, which is required for it to function. 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 can only be duplicated with expensive laser key cutting machines, or specialized software. This technology is most commonly found in luxury cars but is now accessible in a wide range of low-cost models. The VATS (vehicle-anti-theft system), key is another type of key that's 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 car that it's not meant to. These keys are costly and require the use of a key programming machine which is only available at certain locksmiths. VATS Keys Before transponder keys or vehicles with computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). source website utilizes a key that has a resistor embedded in it to ensure that the correct key was used to start the car. The VATS pellet that is black located in the middle of a VATS Key isn't a smart chip like those present on modern keys. It is simply carbon or a block that is sized to have an electrical resistance. GM employed 15 different resistances for VATS pellets and connected them to key blades so that when the key is turned in the ignition a coded message is sent 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 starts to run. This does not make a car burglar-proof, but it can delay a thief for at least fifteen to twenty minutes. After a long period of use, the VATS module can begin to wear out. The two wires inside the ignition are moved every when the key is introduced. Over time the wires could start to break. Once enough of the wires are broken then the signal to the module is not received and it will not start the car. You can solve this issue at home by decoding your VATS key. It's not hard to determine the resistance of a key by using the multimeter. All you need to do is place one of the leads of your ohm gauge on the prongs of metal that are hanging out on both sides of the key, then examine the display of your ohm meter to find out the resistance of your key. This is a great method to test a brand new key and see whether it works in your car. Remove the key from the ignition first before you test it. In the event that it is not removed the key may have an incorrect VATS and not work in your car. Smart Key Fobs for Keys Key fobs today can do more than just unlock or start the vehicle. They are also a security device and a security measure against theft, with many of them featuring advanced features that owners might not be aware of.

This is more than you'd expect from the traditional keychain remote. However, all that additional capabilities can mean that smart key fobs could be pricier to replace than standard keychain remotes and they typically need to be programmed by the dealer. In fact, some dealers will charge up to $100 to replace one smart key fob. This is a significant amount to pay for a device that spends much of its time snagging around in purses and pockets where it can be easily damaged, dropped or exposed to moisture and extreme temperatures. Fortunately there are automakers who have developed ways to safeguard smart key fobs from common kinds of electronic attacks, such as relay attacks. These are often employed 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. To safeguard a smart fob you can put it in a casing made of metal or put it in an RFID blocking case. This will block the transmission of these signals. However, having to remove the key fob from its protective case each time you need to use it is not a good way to enjoy the benefits of the technology. Some newer policies such as auto club memberships or extended warranties can cover the cost of replacing the fob or reimburse you in the event that it's lost. You can also avoid paying dealer fees by having your fob cloned at a locksmith or hardware store that offers key-fob-cloning services. The decision of whether to purchase a new fob is largely dependent on the importance of your car's keyless entry and start functions. In any case it is advisable to keep a spare fob or key in case in case you lose it. Batteries Plus offers a large range of replacement fobs that fit in most vehicles and trucks.

Based on the amount of time that has passed since the last time you cut your keys, there are several different alternatives to pick from when it comes to getting another copy. Certain keys are cut using mechanical machines, while others are laser-cut with added security features. Modern keys have advanced features like encryption and anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or open 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 specific distance of your vehicle. If you opt to utilize a traditional key your locksmith can create an entirely new key using a standard cutter machine, which can be purchased from most hardware stores.
