Car Key Cutting Explained

Car key cutting car key is much more than simply shaping the metal. It is a complicated procedure that ensures safety, functionality and the longevity of keys.

It is not uncommon to lose your car keys or have them break in the lock. To ensure that you can always drive your vehicle you'll need to have a replacement key cut.

Transponder Keys

If your car was constructed in the last 20 years, it is likely to have transponder chips. These microchips are in the handle of the key and transmit a signal to the onboard computers of your vehicle when you turn the key. The computer on board detects the digital serial number within the chip and allows the car to start if it is the correct one. This stops thieves from stealing your car because they'd have to be aware of the unique serial number.

The microchip in the key transmits a low-level signal the receiver within the car. The radio signal activates the microchip, which 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 offer these services can design car keys with chips. They are also available at some automotive retailers like AutoZone. These stores have a wide variety of keys and can assist you in selecting the best one for your vehicle. They can assist you in programming your car's chip, which is required to use the device.

Laser cut keys are more secure than flat keys. These keys feature a lock cylinder that is much harder to pick, and they can only be duplicated using expensive laser key cutting machines or specialized software. This technology is more prevalent in luxury vehicles, but it is now available in many affordable models of cars too.

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

VATS Keys

Before transponder keys or cars that had computer chips built in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a resistor pellet embedded inside it to confirm that the correct key is used to start the vehicle. The VATS pellet in black located in the middle of a VATS Key is not a smart chip as used on the majority of modern keys. It is simply a block or carbon that is sized to hold an electrical resistance value.

GM used 15 different resistance values for the VATS pellets. They attached the key's blade so that when the key is turned on the ignition a coded signal will be 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 begins to run. This doesn't make a car secure from burglary, but it can delay the thief for a minimum of fifteen to twenty minutes.

After a long period of use the VATS module could begin to wear out. The two small wires in the ignition move each time a key is introduced. Over time the wires could begin to break. When enough wires are broken the signal to the module gets not received and it will not start the car.

The good news is that you can fix this issue yourself by decoding your VATS key. You'll need a multimeter and a chart to determine the resistance value of your key, but it is not that difficult. All you have to do is place one of the leads of your ohm meter onto the metal prongs that are visible on both sides of the key, and then look at the display of the ohmmeter to determine the resistance of your key.

This is also a good way to test the new key to determine if it will work in your car. Be sure to remove the key from the ignition prior to testing it, as the new key could be displaying an incorrect VATS number and will not work in your car.

Smart Key Fobs for Keys

Today's key fobs do more than just unlock or start cars. A lot of them come with advanced features that a lot of owners aren't aware of. They can be employed as a security tool or as a deterrent to theft. They can remotely lock and unlock your doors, emit chirping sounds to help you locate your vehicle in a parking lot, or even let you summon your vehicle by pressing a button on your smartphone. This is a lot more than you could ever expect from the traditional keychain remote. Unfortunately, all that added functionality can mean that smart key fobs can be pricier to replace than standard keychain remotes, and they usually need to be programmed by the dealer.

In fact, some retailers will cost upwards of $100 to replace one smart key fob. That's a lot to pay for a device that spends a lot of its time snagging around in pockets and purses, which is where it's easily damaged, dropped, or exposed to extreme humidity and temperatures. Fortunately certain automakers have come up with methods to shield smart key cut place fobs from common types of electronic attacks like relay attacks. They are usually paired with a remote start hack which allows thieves to access your vehicle's settings through the transmission of a fake signal from another transmitter close to.

To safeguard a smart fob to protect it, you can place it in a casing made of metal or put it in an RFID blocking case. This will stop the transmission of these signals. However, having to remove the key fob from a protective case each time you use it is not a good way to enjoy the benefits of the technology.

Certain policies that are more recent such as auto club memberships or extended warranties, will cover the cost of replacing the fob, or reimburse you if it is lost. You can also avoid paying new-car dealer fees by having your fob cloned at a hardware or locksmith store that offers key-fob-cloning services.

They can unlock your locks and open the car, provided you don't swap them out to a smart or remote key. The only disadvantage of using traditional keys is that it must be physically put into the ignition in order to start the car. If your traditional car key is lost or broken, you will need to visit the Gainesville locksmith to get a new one made.

There are several options to choose from depending on how long it's been since you've had your keys cut. Certain keys cut in my area employ mechanical cutting machines to make copies, while others employ laser-cut keys that have been specifically designed with enhanced security features in mind.

Modern keys have advanced features, such as encryption and anti-theft mechanisms. The encryption ensures that only the right key is used to open your vehicle, making it more difficult for thieves to duplicate keys or pick locks. Other security features to prevent theft include transponder chips that are embedded into the keys to connect with your car and make it only work when it's within a certain distance of your car.

Another option is to have your standard car key replaced with a laser cut version with a unique pattern.
