Car Key Cutting Explained

Car key cutting is more than simply shaping the metal. It is a complicated procedure that ensures security, functionality and the longevity 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 you can drive your vehicle at all times.

Transponder Keys

Transponder chips are likely to be added to cars that were built within the past 20 years. These microchips are located in the key's handle and transmit a signal to your vehicle's onboard computers when you use the key. The computer on board reads the digital serial number within the chip and allows the car to start if it is the correct one. This prevents car thieves from stealing your car since they'd need to be aware of the unique serial number.

The microchip inside the key transmits a low-level signal the receiver within the car. The radio signal activates microchip, which then transmits a code to the car's onboard computer. The car key blade cutting will only start only if it recognizes the code. This will stop "hot wiring" or other methods to steal cars.

Car keys with chips can be made at locksmiths that offer these services. Some automotive retailers such as AutoZone offer keys with chips. These stores have a large range of keys and can help you find the best one for your vehicle. They can even assist you to programme the chip into your vehicle, which is necessary to make it work.

Laser cut keys 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 with expensive laser key cutting equipment or specialized software. This technology is more common in high-end cars, but it is now accessible in many affordable models of cars as well.

Another type of key for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. The keys have a resistor that is black on the blade of the key. It can be programmed to one of a variety of values to prevent it from starting a car that's not designed to. These keys are more expensive to buy and require a special key cutting key programming device that can only be located at certain locksmiths.

VATS Keys

Before the days of transponder keys and cars equipped with 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 an internal resistor to verify that the correct key cut service; sciencewiki.science, was used to start the car. The VATS black pellet that is in the center of a VATS key is not an electronic chip like the ones present in modern smart keys, it's simply a piece of carbon that is sized appropriately to have an exact electrical resistance.

GM employed 15 different resistances for the VATS Pellets. They attached them to key blades in a way that, when the key was turned in the ignition the key blades transmit a coded message 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 doesn't make a car burglar-proof however, it can deter a thief for at least 15 to 20 minutes.

Unfortunately, after a significant amount of usage, the VATS module in your car could start to wear out. The two wires that connect the ignition move each time a key is introduced. Over time, the wires may start to break. Once enough of the wires are broken then the signal to the module is not received and it will not start the car.

The good news is that you can fix this issue at home by decoding your own VATS key. It's not difficult to determine the resistance value of a key by using a multimeter. All you need to do is put one of the leads of your ohm gauge on the metal prongs that are visible on both sides of the key. Then look at the display of the ohmmeter to find out the resistance value of your key.

This is a great method to test a brand new key and check 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 may have an incorrect VATS, and will not work in your vehicle.

Smart Key Fobs

Today's key fobs do more than just unlock or start the car. Many of them have advanced features that many owners are unaware of. They can be employed as a security tool or as a theft deterrent. They can remotely lock and unlock your doors, emit noises that help you find your vehicle in a parking lot, or even allow you to summon your vehicle by pressing the button on your phone. This is more than you could ever expect from the traditional keychain remote. Smart key fobs are more expensive to replace due to their extra functionality. They also require to be programmed by the dealer.

Fortunately there are automakers who have developed methods to shield smart key fobs from the most common kinds of electronic attacks, such as relay attacks. They are typically utilized in conjunction with a remote-start hack that allows thieves to access the settings of your vehicle by sending false signals from a nearby transmitter.

To safeguard a smart fob, you can store it in a casing made of metal or put it in an RFID blocking case. This will block the transmission of these signals. The ease of use of this technology is compromised if you must remove your key fob each time you take it out of the protective case.

Some newer policies such as auto club memberships and extended warranties, will pay for replacing the fob or reimburse you in the event that it's lost. You can also avoid paying dealership fees by having your fob cloned by a locksmith or hardware store that offers key-fob-cloning services.

For most drivers who want to buy 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 a spare fob or key in case you lose yours. Batteries Plus offers a large choice of replacement fobs that fit on most cars and trucks. Additionally, our fast and easy service is about 50% less than the price you would spend at a dealership.

Traditional Keys

Traditional car keys are a single length of metal that has grooves cut into it to fit in a specific lock. These keys will unlock your locks and also start the car, provided you haven't changed them out to a smart or remote key. The only disadvantage of using an old-fashioned car key is that you must physically insert it into the ignition to start the engine. If your key from the past is lost, damaged or stolen, you'll need to visit a Gainesville locksmith to get an alternative one made from the blank.

Depending on how much time has passed since the last time you got your keys cut, there are several different options available for you to choose from when it comes to getting another copy. Certain keys employ mechanical cutting machines to create copies, while others use laser-cut keys that are designed with enhanced security features in mind.

Modern keys have advanced features like encryption and anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or open locks. Transponder chips are an additional anti-theft feature. They are incorporated into the key and communicate with your vehicle. This means that it can only work when you're within a certain distance.

If you decide to use a traditional, standard key, a locksmith could make a new one using a standard key cutter machine that can be found at the majority of hardware stores. This is less expensive than the key fob or transponder key, and you'll still be able to operate your locks, doors and trunk.

Another alternative is to get your standard car key replaced with a laser-cut version with a distinctive pattern. These keys were first introduced in the 1990s and are a popular option for those who want to safeguard their vehicles. Laser cut keys are typically equipped with transponder chip that is programmed to work only with your vehicle. If these chips are not installed in your vehicle, it will not respond to the signals generated by the key.
