Car Key Cutting Explained

Car cheap key cutting cutting is much more than just forming an object of metal. It is a sophisticated process that guarantees security, functionality, and longevity of the keys.

It is not uncommon to lose your car keys or have them break through the lock. To ensure that you are able to always drive your vehicle, you will need to have a replacement key cut.

Transponder Keys

If your car was constructed within the last 20 years, it is likely that it has a transponder chip. These microchips are situated in the key's handle and transmit a signal your vehicle's onboard computers when you press the key. The onboard computer scans the digital serial numbers inside the chip and allows the car to start if it's the correct one. This helps prevent theft of cars, as thieves would need to know your unique serial number to have a chance at hijacking it.

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

Locksmiths who offer these services can design keys for cars that contain chips. Some automotive retailers such as AutoZone offer them. They have a vast range of keys and will assist you in choosing the appropriate one for your car. They can help you program the chip in your vehicle that is required for the device to function.

Laser cut keys are more secure than flat keys. They have an cylinder for locking that is more difficult to pick, and can only be duplicated with expensive laser key cutting equipment or specially designed software. This technology is more common in high-end vehicles, however it is now being used in many affordable models of automobiles as well.

The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. The keys are black with a resistor on the key blade that is programmed with one of 15 potential values to prevent them from starting a car that it's not designed to. These keys are costly and require an instrument for programming keys, which is only available 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 makes use of a key with an embedded resistor to confirm that the right key was used to start the car. The VATS pellet in black in the middle of a VATS Key isn't an electronic chip that is like those used on the majority of modern keys. It's just carbon or a block which is sized to hold an electrical resistance.

GM employed 15 different resistances for VATS pellets and connected them to key blades in a way that, when the key was turned in the ignition the key blades transmit a coded message 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 does not make a car burglar-proof however it could delay thieves for at least fifteen to twenty minutes.

Unfortunately, after a lot of use the VATS module in your car may start to wear out. Each time a key is inserted into the ignition it reroutes two small wires inside the ignition and with time, the wires can start to break. When enough wires break, 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 value of a key using the multimeter. You can find the resistance value by placing one of the leads on the prongs of metal on both sides of your key.

This is a great method to test a new key and check if it works in your vehicle. Remove the ignition key first before you test it. Otherwise the key may have an incorrect VATS and not function in your vehicle.

Smart Key Fobs for Keys

Key fobs today can do more than simply unlock and start the car. A lot of them come with advanced features that many owners are unaware of. They can be employed as a security tool or a theft deterrent. They can remotely lock and unlock your doors, emit sounding sounds to help locate your car in a parking space, or even allow you to summon your vehicle by pressing the button on your smartphone. This is a lot more than you could ever think of from a standard keychain remote. Smart key fobs are more expensive to replace because of their extra functionality. They also have to be programmed at the dealer.

Some dealers will charge up to $100 for a single smart fob. That's a huge sum to pay for a product that is often time snagging around in purses and pockets, where it is easily damaged, dropped, or exposed to moisture and extreme temperatures. Certain automakers have developed strategies to shield smart key fobs from common electronic attacks, like relay attacks. They are typically utilized in conjunction with remote-start hacks that allow thieves to access your vehicle's settings by transmitting a fake signal from another nearby transmitter.

To secure a smart card you can put it in a metal casing or even an RFID blocking case. This will stop the transmission of these signals. However, having to remove the key fob from its protective case each time you want to make use of it is a hassle and a detriment to the efficiency of the technology.

Fortunately, a few of the latest car insurance policies such as auto club memberships and extended warranty coverage will cover the cost of replacing a fob or reimburse you for a lost fob. You can also avoid paying new-car dealer fees by having your fob cloned at a hardware or locksmith retailer that provides key-fob cloning.

These keys can open your locks and open the car, assuming you haven't changed them out for a smart key or remote key. The only downside of using an old-fashioned car key is that you have to physically insert it into the ignition to start the engine.

Some of these advanced features that are included in modern-day keys include encryption as well as other security mechanisms. Encryption makes sure that only the correct key is used to start your vehicle making it much more difficult for thieves to duplicate or pick locks. Other security features to prevent theft include transponder chips that are embedded in the key to communicate with your car and make it only work when it's within a certain distance of your car.
