Car Key Cutting Explained

Car key cutting is a lot more than simply shaping an object of metal. It is a complicated process that ensures security, functionality and durability of keys.

It is not uncommon to lose your car keys or even break it in the lock. You'll require a replacement car key to ensure you can drive your vehicle at all times.

Transponder Keys

If your car was manufactured within the last 20 years, it is likely to have a transponder chip. These microchips are tiny located in the handle of your key that send an electronic signal to the car's onboard computer whenever you use it. The computer in the car detects the digital serial number inside the chip and allows the car to start if it's the correct one. This stops thieves from hijacking your vehicle, as they would need to be aware of the unique serial number.

The microchip inside your car key sends an low-level radio signal to the car's receiver. This radio signal activates the microchip which then transmits instructions to the onboard computer of the car. The car will only start only if it recognizes the code. This prevents the use of "hot wiring" and other methods of taking cars.

Locksmiths who offer these services can make keys for cars with chips. Some automotive retailers such as AutoZone offer them. These stores have a large selection of keys, and can help you find the appropriate one for your vehicle. They can assist you in programming your car's chip that is required to operate the device.

You can also get laser cut keys, which are more secure than traditional flat keys. These keys feature the lock cylinder, which is much more difficult to pick, and are only duplicated using expensive laser key cutting equipment or special software. This technology is most commonly found in luxury cars, but is now available on many affordable models.

Another type of key for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. These keys feature a black resistor in the 24 hour key cutting blade that is programmed with one of 15 possible values to stop them from starting a vehicle that it's not intended to. These keys are more expensive to buy and require a specific key programming machine that can only be found at a few locksmiths.

VATS Keys

Before the days of transponder keys and cars with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with a resistor embedded in it to ensure that the correct key was used to start the car key cutting price. The VATS pellet in black that is located in the middle of the VATS Key isn't a smart chip like those present on modern keys. It is merely carbon or a block which is sized to hold an electrical resistance value.

GM employed 15 different resistances for the VATS Pellets and connected them to key blades so that when the key is turned on, the key blades transmit a coded message to module. If the signal matches that of the transistor in a VATS pellet, then the relay in the starter circuit will activate and the engine will begin to run. This doesn't make a vehicle safe from theft however it can delay the thief by at least 15 to 20 minutes.

After a long period of use the VATS module could begin to wear out. The two wires inside the ignition are moved each when the key is inserted. Over time, the wires may begin to break. Once enough of the 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 code. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it is not difficult at all. All you need to do is put one of the leads of your ohm meter on the prongs made of metal hanging out on both sides of the key, and then examine the display of your ohm meter to determine the resistance value of your key.

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

Smart Key Fobs for Keys

Key fobs today can do more than just unlock or start the car. They often have advanced features that a lot of owners are not aware of. They can be employed as a security tool or as a theft deterrent. They can lock and unlock your door remotely, make chirping noises to aid in locating your vehicle when you're in a hurry, or allow you to call it up by pressing the button. This is a lot more than you could ever imagine from a traditional keychain remote. Unfortunately, all that extra capabilities also means that smart key fobs could be pricier to replace than standard keychain remotes and they typically need to be programmed by the dealer.

In fact, some dealers will cost upwards of $100 to replace a single smart key fob. That's a lot to pay for something that is often time snagging around in purses and pockets which is where it's easily damaged, dropped or exposed to extreme humidity and temperatures. Certain automakers have developed strategies to shield smart key fobs from common electronic attacks, such as relay attacks. These are typically combined with remote start hacks that allows thieves access to your vehicle's settings via the transmission of a fake signal another transmitter close to.

One way to protect the smart key fob is to store it in a metal case or a dedicated RFID blocking case that prevents the transmission of these signals. However, having to remove the key fob from its case that is protected each time you want to use it is not a good way to enjoy the benefits of the technology.

Some of the newer policies, such as auto club memberships or extended warranties can cover the cost of replacing the fob, or reimburse you if it gets lost. You can also avoid paying new-car dealer fees by having your fob copied by a locksmith or hardware retailer that provides key-fob cloning.

For most drivers who are buying a new key fob depends on the importance of your car's keyless entry and push-button starter functions are. In any event you should have an extra fob or key in case you lose yours. If you have to purchase a new replacement, Batteries Plus has a wide selection of fobs for the majority of vehicles and trucks. Additionally, our fast and convenient service costs about 50% less than what you would pay at the dealership.

Traditional Keys

The car key of old is made of a single piece of steel with a series grooves carved into it. These grooves are made to fit certain locks. These keys will unlock your locks and also start the car, assuming you haven't changed them out to a smart or remote key. The only disadvantage of using the traditional car key is that you must physically insert it into the ignition to start the engine. If your car key is damaged or lost it is necessary to visit a Gainesville locksmith to get car key cut a new one created.

There are a variety of choices to pick from based on how long it has been since you've were able to cut your keys. Certain keys employ mechanical cutting machines to create copies, while others employ laser-cut keys that are designed with enhanced security features in mind.

Some of these modern features that come with modern keys include encryption and other security mechanisms. The encryption makes it difficult for thieves to duplicate keys or take locks. Transponder chips are another anti-theft device. They are embedded in the key and communicate with your vehicle. This means that it can only effective only when you're within a specific distance.

If you choose to make use of a traditional key, your locksmith can make an entirely new key using the standard cutter machine that is available from most hardware stores. This is less expensive than a key fob or a transponder key cutter, and you'll be able to operate your locks, doors and trunk.

You could also replace your traditional keys for your car with a laser cut version that has an unique pattern. These keys were first introduced in the early 1990s and are a popular choice for those looking to safeguard their vehicles. Keys made of lasers are typically equipped with transponder chips programmed to work only with your vehicle. If these chips aren't present in your car, it won't respond to the signals from the key and won't start.
