Car Key Cutting Explained

cutting key a car key is more than just bending a piece of metal. It is a complicated procedure that ensures safety, functionality and durability of keys.

It is not uncommon to lose keys to your car or have them break in the lock. You'll need a new car key in order to ensure that you are able to drive your vehicle at all times.

Transponder Keys

If your car was manufactured within the past 20 years, it is likely to have transponder chips. These microchips are in the key's handle and transmit a signal the onboard computers of your vehicle when you use the key. The onboard computer reads the digital serial number in the chip and only allows the car to start if it is the correct one. This helps prevent theft of cars since thieves need to know your unique serial number in order to have a chance at hijacking it.

The microchip in the key sends a low-level signal the car's receiver. The radio signal activates microchip, which then transmits a code to the car's onboard computer. The car will recognize this code and only allow it to start if the key is the right one. This stops the use of "hot wiring" and other methods of stealing cars.

Locksmiths who provide these services can make keys for cars that contain chips. Some car dealers, like AutoZone offer keys with chips. They have a vast range of keys and will assist you in selecting the best one for your car. They can help you program your car's chip which is needed to use the device.

There are also laser cut keys, which are more secure than flat keys. These keys feature an cylinder for locking that is much more difficult to pick, and they can only be duplicated using expensive laser key cutting machines or with specially designed software. This type of technology is typically found in high-end cars however, it is now available in a wide range of low-cost models.

The VATS (vehicle-anti-theft system) nearest key cutting is another kind of key that is difficult to duplicate. These keys feature a black 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 more expensive to purchase and require a specific key programming machine that can only be found at a few locksmiths.

VATS Keys

Before transponder keys and cars with 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 being used to start the vehicle. The black VATS Pellet that is located in the middle of the VATS Key is not an electronic chip that is like those present on modern keys. It is simply carbon or a block which is sized to have an electrical resistance value.

GM used 15 different resistances for the VATS Pellets. They attached the key blades to them so that when the key is turned in the ignition a coded message is sent to 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 15 to twenty minutes.

After a lot of usage, the VATS module can begin to wear out. Each time a key is inserted into the ignition, it reroutes two small wires within 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 won't start.

You can solve this issue at home yourself by decoding your VATS code. It's not hard to determine the resistance of a key with the multimeter. You can determine the resistance value by placing one of the leads on the prongs made of metal on both sides of your key.

This method is also a good way to test a new key to see whether it works in your car. Be sure to remove the motorcycle key cutting from the ignition prior to testing it, otherwise the new key may have an incorrect VATS value and not function in your car.

Smart Key Fobs for Keys

Key fobs today do more than simply unlock and start the vehicle. They can also be an alarm system and a burglar deterrent, with a lot of them having advanced features that owners may not even know about. They can lock and unlock your door from a distance, make chirping noises to help you locate your vehicle when you're in a hurry, or allow you to summon it by pressing the button. This is a lot more functionality than you get from a traditional keychain remote. Smart key fobs are more expensive to replace due their extra functions.

In fact, some dealers charge upwards of $100 to replace one smart key fob. That's a lot to pay for a device that is often time jostled around in pockets and purses, where it is easily dropped, damaged, or exposed to extreme moisture and temperatures. Certain automakers have developed strategies to shield smart key fobs from common electronic threats, including relay attacks. They are usually paired with remote start hacks that gives thieves access to your vehicle's settings by the transmission of a fake signal another transmitter near.

One way to protect the smart key fob is to store it in a metal case or use a dedicated RFID blocking case that prevents the transmission of these signals. The convenience of the technology is diminished if you have to remove your key fob each time you need to use it from the case.

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

For the majority of drivers, the decision to purchase an additional key fob is contingent on how crucial your car's keyless entry and push button starter functions are. You should always keep a spare fob or key in case you misplace yours. Batteries Plus offers a large choice of replacement fobs that will fit most cars and trucks. Plus, our quick and easy service is about 50% less than the price you'd spend at a dealership.

Traditional Keys

Traditional car keys are a single length of metal with a series of grooves cut into it to fit in a specific lock. These keys will unlock your locks and open the car, as long as you don't swap them out to a smart or remote key. The only drawback to using the traditional car key is that you have to physically insert it into the ignition to start the engine. If your traditional car key has been damaged or lost, you will need to visit an Gainesville Locksmith to get a new one made.

Depending on how much time has passed since the last time you cut your keys there are a variety of options available for you to pick from when it comes to having another copy made. Certain keys are cut using mechanical machines, while others are laser-cut with enhanced security features.

Modern keys come with advanced features, such as encryption and anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or pick locks. Other security features that prevent theft include transponder chips that are incorporated into the key to connect with your car and make it only work when it's within the distance of your car.

If you opt to make use of a traditional key, your locksmith can create the new key using an ordinary cutter machine that is available at most hardware stores. This is cheaper than using the key fob or transponder key, and you'll still be able to use your locks, doors and trunk.

You can also replace your standard car keys with a laser-cut version that has an unique pattern. The first keys of this kind were released in the early 1990s and are an increasingly popular choice for those looking to protect their vehicles. Keys made of lasers are typically equipped with transponder chips programmed to work only with your vehicle. If these chips are not present in your vehicle, it won't respond to the signals generated by the key.
