Car Key Cutting Explained

Car key cutting is much more than just shaping the metal. It is a complex process that guarantees security, function and durability of keys.

It is not unusual to lose keys to your car, or have them break in the lock. You'll require a new car key in order to ensure that you can drive your vehicle at all times.

Transponder Keys

If your car was built in the past 20 years, it's likely to have a transponder chip. These microchips are located in the handle of the van key cutting and transmit a signal the onboard computers in your vehicle when you turn the key. The onboard computer checks the serial number digitally of the chip prior to it allows the car to start. This stops thieves from taking over your vehicle, as they would need to be aware of the unique serial number.

The microchip in your car key transmits a low-level radio signal to the car's receiver. The radio signal activates your microchip which then transmits code to the computer onboard of the car. The car will only begin only if it recognizes the code. This stops "hot wiring" or other methods of stealing cars.

Locksmiths who provide these services can make car keys with chips. Some auto dealers like AutoZone sell them. They have a huge variety of keys, and can help you find the best one for your car. They can even assist you to program the chip to your vehicle, which is required for it to function.

You can also purchase laser cut keys, which are more secure than traditional flat keys. These keys feature an cylinder for locking that is more difficult to pick, and they are only duplicated using expensive laser key cutting machines or special software. This technology is most commonly found in luxury cars, but is now available in a wide range of low-cost models.

The VATS (vehicle-anti-theft system) key is another kind of key that is difficult to duplicate. They have a resistor that is black on the blade of the key. It can be programmed to one of fifteen possible values to stop it from starting a car that's not designed to. They are expensive and require an instrument for programming getting keys cut, which is only available through certain locksmiths.

VATS Keys

Before the days of transponder keys and cars equipped with computer chips that 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 located in the middle of a VATS Key is not a smart chip as found on most modern keys. It's just carbon or a block that is sized to provide an electrical resistance value.

GM used 15 different resistances for emergency key cutting the VATS Pellets. They connected the key blades to them so that, when the key is turned in 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 the starter circuit will be activated and the engine will start to run. This doesn't make a car burglar-proof, but it can delay thieves for at least 15 to 20 minutes.

Unfortunately, after a lot of use the VATS module in your car can start to wear out. The two wires that connect the ignition move each when the key is inserted. As time passes the wires can begin to break. Once enough wires are broken, the signal to the module is lost and it won't start the car.

You can solve this issue at home by decoding your VATS key. It's not difficult to determine the resistance of a key with a multimeter. All you need to do is place one of the leads of your ohm meter onto the prongs made of metal hanging out on both sides of the key, and my explanation then read the ohm meter's display to determine the resistance value of your key.

This is also a good way to test a new key to see whether it will work in your car. Remove the key from the ignition first before you test it. In the event that it is not removed the key could have an incorrect VATS, and will not work in your vehicle.

That's a huge sum to pay for a product that spends much of its time snagging around in purses and pockets, where it is easily dropped, damaged or exposed to extreme humidity and temperatures. Certain automakers have developed strategies to protect smart key fobs from common electronic attacks, like relay attacks. These are typically combined with remote start hacks that gives thieves access to your vehicle's settings through the transmission of a fake signal another transmitter near.

One method to safeguard the smart key fob is to store it in an aluminum case or a specially designed RFID blocking case that blocks the transmission of these signals. However, having to remove the key fob from its case that is protected each time you make use of it is a hassle and a detriment to the efficiency of the technology.

Some of the newer policies such as auto club memberships and extended warranties, will pay for a replacement fob or reimburse you if it gets lost. You can also avoid paying dealership fees by having your fob copied at a hardware or locksmith store that offers key-fob-cloning.

These keys will unlock your locks and start the car, assuming you haven't changed them out for a smart key or remote key. The only drawback to using the traditional key is that it must be physically put into the ignition to start the vehicle. If your traditional car key has been lost or broken you'll need to visit a Gainesville Locksmith to have a new one created.

There are several options to select from based on how long it's been since you had your keys cut. Some keys are cut using mechanical machines or lasers, while others are cut with security features that are enhanced.

Other security features that prevent theft include transponder key cutting near me chips, which are embedded in the 24 hour key cutting to communicate with your car and make it work only when it's within the distance of your car.
