Car Key Cutting Explained
Cutting keys for cars is more than just bending a piece metal. It is a sophisticated process that guarantees security, functionality, and longevity of the keys.
It is not uncommon to lose your car key or have it break off in the lock. To ensure that you can always drive your vehicle, you will require a replacement key cut.
Transponder Keys
Transponder chips are likely be installed in cars built in the last 20 years. These microchips are in the handle of the key and transmit a signal the onboard computers of your vehicle when you turn the key. The computer onboard is able to verify the serial number digitally of the chip before it allows the car to start. This prevents car theft, as thieves would need to know your unique serial number to be able to steal it.
The microchip inside the key sends a low-level signal the receiver within the car. This radio signal activates the microchip that then transmits the code to the computer onboard of the car. The car will only begin when it recognizes the code. This will stop "hot wiring" or other methods to steal cars.
Locksmiths that offer these services can design keys for cars with chips. Some automotive retailers such as AutoZone offer them. They have a huge variety of keys, and can assist you in choosing the right one for your car. They can even help you programme the chip into your vehicle, which is necessary to make it work.
You can also get laser cut keys that are more secure than conventional flat keys. These keys are more secure than traditional flat keys due to the fact that they have locks that are harder to pick. They can only be duplicated with expensive laser key cutting equipment, or with specialized software. This type of technology is typically found in luxury cars however, it is now available on many affordable models.
Another kind of car key that's difficult to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the key blade that is programmed with one of 15 potential values to prevent the car from starting that it's not meant to. These keys are expensive and require a key programming machine, which is only available at a few locksmiths.
VATS Keys
Before the days of transponder keys as well as cars equipped with computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has a resistor embedded in it to confirm that the right key was used to start the car. The VATS pellet in black that is located in the middle of the VATS Key is not a smart chip like those found on most modern keys. It is merely a block or carbon that is sized to have an electrical resistance value.
GM employed 15 different resistance values for VATS pellets and connected them to the key's blade, so that when the key is turned on in the ignition, a coded signal 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 doesn't make a car burglar-proof however, it can deter thieves for at least 15 to twenty minutes.
Unfortunately, after a lot 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 inside the ignition and, over time, the wires can begin to break. Once enough wires are broken, the signal is lost to the module and the car will not start.
You can resolve this issue at home by decoding your VATS code. It's not difficult to determine the resistance of a key using a multimeter. All you have to do is put one of the leads of your ohm meter onto the prongs of metal that are hanging out on both sides of the key, and then examine the display of your ohm meter to determine the resistance of your key.
This is also a great way to test a new key to see if it will work in your car. Be sure to remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS value and not work in your car.
Smart Key Fobs with Smart Keys
Key fobs today are more than simply unlock and start the car. They also function as an alarm system and a security measure against theft, with many of them incorporating advanced features that owners might not even know about.

They are usually paired with remote start hacks that allows thieves access to your vehicle's settings by the transmission of a fake signal another transmitter close to.
To safeguard a smart fob to protect it, you can place it in a metal casing or put it in an RFID blocking case. This will stop the transmission of these signals. The convenience of the technology is compromised if you have to remove your key fob each time you want to take it out of the protective case.
Certain policies that are more recent such as auto club memberships and extended warranties will pay for replacing the fob or reimburse you in the event that it is lost.

The only drawback to using the traditional key is that it must be physically put into the ignition to start the car.
