Car Key Cutting Explained Cutting keys for cars is more than just bending a piece metal. It is a complex process that ensures safety, functionality and longevity of keys. It is not uncommon to lose keys to your car or have them break in the lock. You'll need a new car key in order to ensure that you can drive your car at all times. Transponder Keys Transponder chips will likely be installed in cars built in the last 20 years. These chips are tiny microchips inside the handle of your key which transmit a signal to the vehicle's onboard computer when you use it. The onboard computer checks the serial number digitally of the chip prior to it allows the car to start. This stops theft of vehicles since thieves need to know your unique serial number to be able to take over it. The microchip in your car key transmits an unintentional radio signal to the car's receiver. This radio signal activates the microchip, which transmits a code to the onboard computer of the car. The car will only begin if it recognizes this code. This prevents “hot wiring” or other methods of stealing cars. Locksmiths who offer these services can make keys for cars with chips. They can also be bought at some automotive retailers like AutoZone. They have a vast selection of keys and can assist you in choosing the appropriate one for your vehicle. They can help you program your car's chip that is required for the device to function. You can also get laser cut keys, which are more secure than flat keys. They are more secure than traditional flat keys due to having locks that are harder to pick. They can only be duplicated using expensive laser key cutting equipment, or with specialized software. This type of technology is typically found in high-end cars, but it is now accessible in many affordable models of cars as well. The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. They contain a resistor that's black on the blade of the key. It can be programmed to any of fifteen possible values to prevent it from starting a vehicle that's not designed to. These keys are more expensive to purchase and require a special key programming machine that is only located at certain locksmiths. VATS Keys Before transponder keys and cars that had computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has a resistor embedded in it to verify that the correct key was used to start the car. The VATS pellet that is black in the middle of a VATS Key is not a smart chip as found on most modern keys. It is simply carbon or a block which is sized to have an electrical resistance. GM used 15 different resistance values for the VATS pellets and attached them to the key's blade so that when the key is turned on the ignition, a coded signal is sent to the module. If the signal matches the signal of the transistor in a VATS pellet then the relay in starter circuit will be activated and the engine will start to run. This isn't a way to make a car secure from theft, but it will delay the thief by at least 15 to 20 minutes. Unfortunately, after a long period of use the VATS module in your car may begin to wear out. Each time a key is inserted into the ignition it reroutes two small wires within 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. The good news is that you can fix this issue yourself by decoding your own VATS key. It's not difficult to determine the resistance of a key with the multimeter. All you have to do is put one of the leads of your ohm gauge on the prongs of metal that are hanging out on both sides of the key, then read the ohm meter's display to find out the resistance of your key. This is also a great way to test a new key to determine if it will work in your vehicle. Remove the ignition key first before you test it. If not the key may have an incorrect VATS, and will not work in your car. Smart Key Fobs with Smart Keys Today's key fobs are more than just a way to unlock or start the car. They often have advanced features that most owners aren't aware of. They can be used as a security device or a theft deterrent.

They also need to be programmed by the dealer. Some dealers will charge up to $100 for a single smart fob. It's a high cost to pay for a device that is often jostled in purses and pockets where it could be damaged, dropped or exposed to extreme temperatures and humidity. Fortunately certain automakers have come up with ways to protect smart key fobs from common types of electronic threats like relay attacks. They are usually paired with a remote start hack that gives thieves access to your vehicle's settings by the transmission of a fake signal from another transmitter close to. To secure a smart card you can put it in a metal case or put it in an RFID blocking case. This will stop the transmission of these signals. However, the necessity of removing the key fob from its case that is protected each time you need to use it undermines the convenience of the technology. Fortunately, some of the newer car insurance policies, auto club memberships, and extended warranty insurance policies will pay for the cost of replacing a fob or pay for the loss of a fob. You can also save money on new car dealer charges and have your fob cut at the hardware store or locksmith who offers key fob cloning. The decision of whether to purchase a new fob is largely dependent on the significance of your car's keyless entry and start functions.
