Car Key Cutting Explained

Car key cutting is much more than just shaping an object of metal. It is a complicated procedure that ensures security, functionality and long-term use of the keys.

It is not uncommon to lose keys to your car, or have them break through the lock. You'll require an alternative car key to ensure you can drive your car at all times.

Transponder Keys

If your car was constructed in the past 20 years, it's likely to have transponder chips. These chips are tiny microchips in the key's handle that transmit an electronic signal to the car's onboard computer when you are using it. The computer in the car checks the serial number of the chip prior to allowing the car to start. This stops theft of vehicles, as thieves would need to know your unique serial number to have a chance at hijacking it.

The microchip in the key transmits a low-level signal to the car's receiver. This radio signal activates your microchip, which transmits a instructions to the onboard computer of the car. The car will recognize the code and only allow it to start if it is the correct one. This stops 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 sell them. These stores have a large variety of keys, and can help you find the right one for your car. They can even assist you to programme the chip into your vehicle, which is required to use it.

Laser cut keys are more secure than flat keys. They have a lock cylinder that is more difficult to pick, and they are only duplicated using expensive laser key cutting equipment or specially designed software. This type of technology is typically found in luxury cars but is now accessible on many affordable models.

The VATS (vehicle-anti-theft system) key is a different type of key that is difficult to duplicate. These keys have a black resistor in the key blade that is programmed with one of 15 potential values to prevent them from starting a vehicle that it's not designed to. They are expensive and require the use of a key programming machine which is only available at a few locksmiths.

VATS Keys

Before the days of transponder keys and automobiles with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key that has a resistor pellet embedded in it to confirm that the correct key is used to start the car. The VATS pellet that is black in the middle of a VATS Key is not a smart chip like those used on the majority of modern keys. It is merely a block or carbon that is sized to have an electrical resistance value.

GM used 15 different resistances for the VATS Pellets and connected them to key blades in a way that when the key was turned on, the key blades transmit a coded message to module. If the signal is in line with that of the transistor in a VATS pellet then the relay in starter circuit will activate and the engine will begin to run. This does not make a car secure from burglary, but it can delay a thief for at least fifteen to twenty minutes.

Unfortunately, after a long period of usage, the VATS module in your car can start to wear out. Every time a key is inserted into the ignition, it moves two tiny wires within the ignition, and over time the wires may begin to break. Once enough wires are broken the signal goes out to the module and the car won't start.

The good news is that you can solve this problem yourself at home by decoding your VATS key. It's not hard to determine the resistance of a key by using a multimeter. All you have to do is put one of the leads of your ohm gauge on the prongs of metal that are hanging out on both sides of the key, and then look at the display of the ohmmeter to determine the resistance of your key.

This is also a great way to test a new key to see if it will work in your vehicle. Remove the key from the ignition first before you test it. If not, the key may have an incorrect VATS, and will not work in your vehicle.

Smart Key Fobs with Smart Keys

Key fobs today do more than just unlock or start a car. Many of them have advanced features that a lot of owners are not aware of. They can be used as a security device or as a theft deterrent. They can lock and unlock your door from a distance, make chirping noises to aid in locating your vehicle when you're in a hurry or activate it by pressing a button. This is more than you could ever expect from the traditional keychain remote. Smart key fobs are more expensive to replace due their extra functions. They also need to be programmed by a dealer.

In fact, some dealers will charge up to $100 to replace one smart key fob. That's a lot to pay for a device that is often time in pockets and purses, where it can be easily dropped, damaged, or exposed to extreme moisture and temperatures. Some automakers have developed methods to shield smart key fobs from common electronic attacks, like relay attacks. These are often used in combination with a remote-start hack that allows thieves to gain access to the settings of your vehicle by sending an untrue signal from a nearby transmitter.

To secure a smart card you can put it in a metal casing or put it in an RFID blocking case. This will block the transmission of these signals. The ease of use of this technology is diminished if you must remove your key fob every time you need to use it from the case.

Fortunately, some of the newer car insurance policies, auto club memberships, and extended warranty insurance policies will pay for the cost of a replacement or reimburse you for the lost fob. You can also avoid paying new-car dealer fees by having your fob cloned by a locksmith or hardware store that offers key-fob-cloning services.

In any event you should have a spare fob or key in case you lose yours. Batteries Plus offers a large selection of replacement fobs that fit on most cars and trucks. In addition, our quick and efficient service is 50% less than the price you would spend at the dealership.

Traditional Keys

The traditional car key is one piece of metal with a series of grooves carved into it. These grooves are designed to fit certain locks. They can open your locks and begin your car, assuming you don't replace them with an electronic key or a remote key. The only drawback to using traditional keys is that it needs to be physically inserted into the ignition to start the vehicle. If your traditional car key is damaged or lost it is necessary to visit an Gainesville Locksmith to get a new one created.

You have a few options to select from based on how long it has been since you've were able to cut your keys. Certain keys utilize mechanical cutting machines to create copies, while others use laser-cut keys designed with enhanced security features in mind.

Some of these advanced features that are included in modern keys include encryption as well as other security mechanisms. Encryption ensures that only the right key can be used to start your car, making it more difficult for thieves to duplicate or pick locks. Transponder chips are another security feature that prevents theft. They are embedded into the key and communicate with your vehicle. This means that it can only function only when you're within certain distance.

If you opt to utilize a traditional key your locksmith can make the new key using a standard cutter machine, which can be purchased from most hardware stores. This is less expensive than using a key fob or a transponder key, and you'll be able to use your locks, doors and trunk.

You could 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 late 1990s, and they're a popular choice for those who wish to add extra protection to their vehicles. The majority of laser cut keys have special transponder chips that are designed to work only with your specific vehicle. If these chips aren't present in your vehicle it won't receive the signals emanating from the key and won't be able to start.
