Transponder Keys

If your car was constructed in the last 20 years, it is likely that it has a transponder chip. These microchips are situated in the handle of the key and transmit a signal to the onboard computers in your vehicle when you turn the key. The computer in the car reads the digital serial number in the chip and only allows the car to start if it is the correct one. This prevents thieves from taking over your vehicle, as they would need to be aware of the unique serial number.

The microchip inside the key sends a low-level signal the receiver within the car key cutting near me. The radio signal activates microchip, which then transmits an encoded code to the car's onboard computer. The car will be able to recognize the code and only allow it to start if the key is the correct one. This stops "hot wiring" or other methods to steal cars.

Locksmiths who offer these services can make keys for cars that contain chips. Some automotive retailers such as AutoZone offer van keys cut near me with chips.

This technology is more common in high-end cars, but it is now being used in a wide range of low-cost to get a key cut cars too.

The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. The keys are black with a resistor in the key blade that is programmed with one of 15 possible values to stop the car from starting that it's not designed to. These keys are costly and require a key programming machine, which is only available at a few locksmiths.

VATS Keys

Before the advent of transponder keys as well as cars equipped with computer chips that control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an internal resistor to verify that the correct key was used to start the car. The VATS black pellet that is inside the middle of the VATS key isn't an electronic chip as used in modern smart keys. It is simply a piece of carbon that is sized appropriately to have a specific electrical resistance value.

GM employed 15 different resistance values for the VATS pellets. They connected them to the blade of the key so that when the key is turned on the ignition, a coded signal is sent to the module. If the signal is in line with the one of the transistors in a VATS pellet then the relay in starter circuit will be activated and the engine will begin to run. This does not make a car secure from burglary however it could delay thieves for at least 15 to 20 minutes.

After a prolonged period of usage the VATS module may start to wear out. Every time a key is inserted into the ignition, it moves two very small wires inside the ignition, and, over time, the wires may start to break. Once enough wires break, the signal to the module gets lost and the module won't be able to start the car.

The good news is that you can fix this problem yourself at home by decoding your VATS key. It's not hard to determine the resistance value of a key by using a multimeter. All you have to do is put one of the leads of your ohm gauge on the metal prongs that are sticking out on both sides of the key, then examine the display of your ohm meter to determine the resistance value of your key.

This is a great opportunity to test a brand new key and see whether it works in your vehicle. Remove the ignition key first before you test it. In the event that it is not removed the key could have an incorrect VATS and not function in your vehicle.

They are usually paired with remote start hacks which allows thieves to access your vehicle's settings through the transmission of a fake signal another transmitter nearby.

One way to protect the key fob's RFID is to put it in an aluminum case or an RFID blocking case that prevents the transmission of these signals. However, having to remove the key fob from its protective case every time you want to use it is not a good way to enjoy the benefits of the technology.

Some of the newer policies like auto club memberships or extended warranties can pay for an additional fob or reimburse you if it's lost. You can also avoid paying dealer fees by having your fob cloned at a hardware or locksmith store that offers key-fob-cloning.

The only drawback of using the traditional key is that it must be physically put into the ignition in order to start the car. If your key from the past is damaged, lost or stolen, you'll have to visit the Gainesville locksmith to get an alternative one made from the blank.

Depending on how long has passed since the last time you cut your keys, there are several different options to choose from when it comes to getting another copy made. Certain keys are cut using mechanical machines, while others are laser-cut with added security features.

Modern keys have advanced features, such as encryption and anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or take locks.
