Car Key Cutting Explained

Car key cutting is more than just forming a piece of metal. It is a complex procedure that ensures security, efficiency and long-term use of the keys.

It is not unusual to lose your car key 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 constructed in the past 20 years, it's likely to have transponder chips. These microchips are tiny inside the handle of your key that transmit an electronic signal to the car's onboard computer when you are using it. The onboard computer reads the digital serial number in the chip and only allows the car to start if it's the correct one. This prevents car theft as thieves would have to know your unique serial number to be able to take over it.

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

Locksmiths that offer these services can design keys for cars that contain chips. Some auto dealers like AutoZone sell keys with chips. These stores offer a wide range of keys and can assist you in finding the appropriate one for your vehicle. They can even assist you to programme the chip into your vehicle, which is essential to make it work.

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

Another kind of key cutting cost for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. These keys come with a resistor black on the blade of the key. It can be programmed with one of fifteen possible values to stop it from starting a vehicle it's not intended to. These keys are more expensive to buy and require a specific key programming device that can only be found at a few locksmiths.

Keys to VATS

Before the advent of transponder keys and automobiles equipped with computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a resistor pellet embedded within it to verify that the correct key is being used to start the car. The black VATS Pellet in the middle of a VATS Key is not an electronic chip that is like those found on most modern keys. It's just carbon or a block which is sized to have an electrical resistance.

GM employed 15 different resistances for VATS pellets and connected them to key blades in a way that, when the key is turned in the ignition a coded message is sent to module. If the signal matches the signal of the transistor in a VATS pellet then the relay in starter circuit will turn on and the engine will start to run. This doesn't make a car secure from burglary, but it can delay thieves for at least fifteen to twenty minutes.

After a prolonged period of usage, the VATS module can start to wear out. The two wires inside the ignition are moved each time a key is inserted. Over time the wires can start to break. If enough wires are damaged the signal goes out to the module and the car won't start.

The good news is that you can fix this issue at home by decoding your own VATS key. You'll require a multimeter as well as a chart to determine the resistance value of your key, but it's not difficult at all. You can find the resistance value by placing one of the leads on the metal prongs on both sides of your key.

This method is also a great way to test a new key to see whether it works in your vehicle. Make sure you remove the key from the ignition before you begin testing it, or else the new key may have an incorrect VATS value and may not work in your car.

Smart Key Fobs for Keys

Key fobs today do more than simply unlock and start the car. They often have advanced features that many owners aren't aware of. They can be used as a security device or a theft deterrent. They can lock and unlock your door remotely, make chirping noises to assist you in finding your car in a lot or summon it by pressing the button. That's a lot more than you'd expect from the traditional keychain remote. Smart key fobs are more expensive to replace due their additional functions. They also require to be programmed by a dealer.

In fact, some dealers will cost upwards of $100 to replace a single smart key fob. That's a huge sum to pay for a product that spends a lot of its time snagging around in purses and pockets where it can be easily dropped, damaged or exposed to extreme moisture and temperatures. Certain automakers have developed strategies to protect smart key fobs from common electronic attacks, such as relay attacks. These are often combined with a remote start hack that allows thieves access to your vehicle's settings by the transmission of a fake signal from another transmitter nearby.

To safeguard a smart fob, you can store it in a metal case or even an RFID blocking case. This will prevent the transmission of these signals. However, having to take the key fob from its protective case every time you need to make use of it is a hassle and a detriment to the efficiency of the technology.

Fortunately, some of the newer car insurance policies and 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 dealership fees by having your fob cloned by a locksmith or hardware store that offers key-fob-cloning services.

The decision to buy an additional fob is dependent on the significance of your car's keyless start and entry functions. In any event, you should always have an extra key or fob handy just in case you lose it. Batteries Plus offers a large range of replacement fobs that fit most cars and trucks. We also offer a quick, convenient service that is roughly 50% less than you'd pay at the dealership.

Traditional Keys

Traditional car keys are a single length of steel that has grooves cut into it to fit a specific lock. These keys can unlock your locks and start your car, provided you don't replace them with the remote key or smart key. The only disadvantage of using traditional keys is that it must be physically placed into the ignition to start the vehicle. If your traditional car key has been lost or broken, you will need to visit a Gainesville Locksmith to have a new one created.

There are a variety of options to select from based on how long it has been since you cut your keys. Certain keys are cut with mechanical machines and others are laser-cut with security features that are enhanced.

Some of these advanced features that come with the modern keys include encryption as well as other anti-theft mechanisms. Encryption makes it harder for thieves to duplicate keys or pick locks. Other security features to prevent theft include transponder chips, which are embedded into the keys to communicate with your vehicle and allow it to work only when it's within a certain distance of your car.

If you opt to utilize 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 cheaper than a key fob or transponder key cutting near me, and you can still operate your trunk, locks and doors.

You can also replace your traditional car keys with a laser-cut version with a distinctive pattern. The first time these keys were introduced was in the 1990s, and are a popular choice for those who wish to add extra protection to their automobiles. The majority of laser cut keys contain transponder chips that are specifically programmed to work for your specific vehicle. If these chips are not present in your vehicle, it will not respond to the signals sent by the van key cutting.
