Car Key Cutting Explained

Car key cutting is a lot more than just forming the metal. It is a complicated procedure that ensures security, efficiency, and longevity of the keys.

It is not uncommon to lose your car key or even break it in the lock. To ensure that you are able to always drive your vehicle you'll need a new key cut.

Transponder Keys

If your car was built within the past 20 years, it's likely to have transponder chips. These chips are small microchips inside the handle of your key which transmit an electronic signal to the car's onboard computer when you use it. The onboard computer detects 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 to be able to take over it.

The microchip inside the Emergency Key cutting sends a low-level signal the receiver within the car. This radio signal activates the microchip, which then transmits an informational code to the car's onboard computer. The car will only begin when it recognizes the code. This prevents the use of "hot wiring" and other methods of theft of cars.

Car keys with chips can be created at an authorized locksmith who offers these services. Some car dealers, like AutoZone offer them. These stores offer a wide selection of keys, and can assist you in finding the best one for your car. They can help you program your vehicle's chip, which is required for the device to function.

You can also purchase laser cut keys, which are more secure than flat keys. These keys are more secure than flat keys due to the fact that they have locks that are harder to pick. They can only be duplicated using expensive laser key cutting machines, or specialized software. This technology is more prevalent in luxury vehicles, but it is now being used in a variety of affordable automobiles as well.

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

Keys to VATS

Before the days of transponder keys and cars equipped with computer chips to control the ignition of a car, 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 vehicle. The VATS pellet that is black that is located in the middle of the VATS Key is not a smart chip as found on most modern keys. It is simply carbon or a block that is sized to hold an electrical resistance value.

GM used 15 different resistances for the VATS Pellets and attached them to key blades so that when the key is turned in the ignition the key blades transmit a coded message to the module. If the signal matches that of the transistor in a VATS pellet then the relay in the starter circuit will be activated and the engine will begin to run. This doesn't make a vehicle secure from theft, but it will delay the thief by at minimum 15 to 20 minutes.

After a lot of usage the VATS module may begin to wear out. The two small wires in the ignition move each time a key is introduced. Over time, the wires may begin to break. If enough wires are damaged the signal goes out to the module and the car won't start.

You can solve this problem at home yourself by decoding your VATS code. It's not hard to determine the resistance of a key using a multimeter. All you have to do is place one of the leads of your ohm meter onto the prongs made of metal visible on both sides of the key, then examine the display of your ohm meter to find out the resistance value of your key.

This method is also a good way to test the new key to determine if it will work in your car key cutting cost. 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 vehicle.

Smart Key Fobs with Smart Keys

Today's key fobs do more than just unlock or start the car. They also function as a security device and a theft deterrent, with many of them having advanced features that owners may not be aware of. They can remotely lock and unlock your doors, make sounding sounds to help find your vehicle in a parking lot or allow you to summon your vehicle by pressing a button on your smartphone. This is more functionality than you can get from a traditional keychain remote. Smart key fobs are more expensive to replace due to their extra functions. They also require to be programmed by a dealer.

Some sellers charge as much as $100 for a single smart fob. That's a huge sum to pay for something that spends much of its time jostled around in purses and pockets where it can be easily dropped, damaged or exposed to extreme humidity and temperatures. Some automakers have developed methods to protect smart key fobs from common electronic attacks, such as relay attacks. They are typically employed in conjunction with remote-start hacks that allow thieves to access your vehicle's settings through a fake signal from another nearby transmitter.

To secure a smart card you can put it in a metal case or use an RFID blocking case. This will block the transmission of these signals. However, having to remove the key fob from its case that is protected each time you make use of it is a hassle and a detriment to the efficiency of the technology.

Fortunately, some newer car-insurance policies such as auto club memberships and extended warranty insurance policies will pay for the cost of replacing a fob or pay for the loss of a fob. You can also save money on dealer fees and have your fob cut at an establishment like a locksmith or hardware store that offers key-fob cloning services.

For most drivers, the decision to purchase an extra key fob will depend on the importance of your car's keyless entry and push-button start functions are. You should always keep a spare key cutting fob or key on hand in case you lose yours. If you do need to buy a new replacement, Batteries Plus has a wide selection of fobs for the majority of cars and trucks. Additionally, our fast and easy service is about 50% less than what you'd buy from a 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, assuming you don't replace them with the remote key or smart key. The only downside of using the traditional car key is that you must physically insert it into the ignition to start the engine. If your key from the past is lost, broken or stolen, you'll have to visit a Gainesville locksmith to get a new one cut from the blank.

Depending on how long has passed since you last cut your keys there are a variety of alternatives to choose from when it comes time to get another copy made. Certain keys are cut using mechanical machines, while others are laser-cut with added security features.

Some of these features that come with the modern types of keys include encryption as well as other security mechanisms. Encryption ensures that only the right key is used to open your vehicle, making it more difficult for thieves to duplicate or pick locks. Transponder chips are an additional anti-theft feature. They are embedded in the key and can communicate with your vehicle. This means that they only function when you're within a certain distance.

If you decide to use a traditional standard key, a locksmith is able to create a new one with a standard key cutting machine, which is available at most hardware stores. This is cheaper than a key fob or transponder, and you can still operate your trunk, locks and doors.

You can also replace your traditional car keys with a laser-cut version that has an unique pattern. The first time these keys were introduced was in the late 1990s, and are a popular choice for those who wish to enhance the security of their vehicles. The majority of laser cut keys have special transponder chips that are specifically programmed to work with the specific vehicle you own. If these chips aren't present in your vehicle they will not respond to the signals generated by the key.
