Car Key Cutting Explained

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

It is not unusual to lose keys to your car or have them break in the lock. You'll need an alternative car key to ensure that you can drive your car at all times.

Transponder Keys

If your car was constructed in the last 20 years, it's likely that it has transponder chips. These chips are small microchips inside the handle of your key that transmit a signal to the vehicle's onboard computer whenever 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 right one. This stops thieves from taking over your vehicle, as they would need to know the unique serial number.

The microchip inside the key transmits a low-level signal to the receiver within the car. The radio signal activates microchip, which then transmits an informational code to the car's onboard computer. The car will be able to recognize this code and will only allow it to start when it is the correct one. This stops the use of "hot wiring" and other methods of taking cars.

Car keys with chips can be made by an authorized locksmith who offers these services. Some auto dealers like AutoZone sell them. Those stores carry a huge variety of keys and can assist you in selecting the best one for your vehicle. They can help you program your vehicle's chip which is needed to operate the device.

Laser cut keys are more secure than flat keys. They have the lock cylinder, which is more difficult to pick, and they can only be duplicated using expensive laser key cutting equipment or specially designed software. This type of technology is typically found in high-end vehicles, however it is now being used in a variety of affordable cars too.

Another type of special key cutting for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor on the blade of the key that is programmed with one of 15 possible values to prevent the car from starting that it's not designed to. These keys are expensive and require a key programming machine, which is only available at certain locksmiths.

VATS Keys

Before the days of transponder keys and cars with built-in computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key that has a resistor pellet embedded in it to confirm that the correct key is being used to start the vehicle. The VATS black pellet that is located in the middle of a VATS key is not a chip like those used in modern smart keys, it's simply a block of carbon properly sized to carry an exact electrical resistance.

GM used 15 different resistances for the VATS Pellets and connected the key blades to them so that, when the key is turned in the ignition a coded signal is sent to module. If the signal matches the one of the transistors in a VATS pellet then the relay in starter circuit will activate and the engine will start to run. This doesn't make a car safe from theft, but it will delay the thief by at least 15 to 20 minutes.

Unfortunately, after a significant amount of usage, the VATS module in your car could begin to wear out. Every time a key is inserted into the ignition, it moves two very small wires inside the ignition, and with time, the wires may start to break. When enough wires break, the signal to the module gets lost and it won't start the car.

The good news is that you can fix this issue at home by decoding your VATS automotive key cutting near me. You'll need a multimeter and an indicator chart to determine the resistance value of your key, but it is not that difficult. All you have to do is place one of the leads of your ohm meter on the prongs of metal 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 way to test out a new key and see whether it will work in your car. Remove the ignition key first before you test it. If not the key could have an incorrect VATS and not work in your car.

Smart Key Fobs with Smart Keys

Key fobs today can do more than just unlock or start the vehicle. They are also an alarm system and a burglar deterrent, with a lot of them incorporating advanced features that owners may not even be aware of. They can remotely lock and unlock your doors, make chirping sounds to help you locate your car in a parking space, or even let you summon your vehicle by pressing the button on your phone. This is more functionality than you can obtain from a traditional keychain remote. Smart key fobs are more expensive to replace due their additional functions. They also need to be programmed at the dealer.

Some dealers will charge up to $100 for one smart fob. That's a huge sum to pay for a device that spends much of its time in purses and pockets, 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. They are typically employed in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings by transmitting a fake signal from another nearby transmitter.

One way to protect a smart key fob is to store it in a metal case or a dedicated RFID blocking case that blocks the transmission of these signals. However, having to remove the key fob from a case that is protected each time you want to make use of it is a hassle and a detriment to the efficiency of the technology.

Some newer policies like auto club memberships and extended warranties will cover the cost to get a key cut of a replacement fob or reimburse you in the event that it is lost. You can also save money on new-car dealer charges and have your fob cut at a hardware store or locksmith which offers key-fob cloning.

For the majority of 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 case you should have an extra key or fob handy just in case you lose yours. Batteries Plus offers a large choice of replacement fobs that fit most cars and trucks. Plus, our quick and convenient service costs about 50% less than what you'd buy from the dealership.

Traditional Keys

Traditional car keys are a single piece of steel that has a series of grooves cut into it to fit a specific lock. These keys will unlock your locks and start the car, assuming you don't swap them out to a smart or remote key. The only disadvantage of using a traditional key is that it must be physically put into the ignition in order to start the car. If your traditional key has been lost, broken or stolen, you'll have to visit a Gainesville locksmith to have an alternative one made from the blank.

There are several choices to pick from based on how long it's been since you've cut your keys. Some keys use mechanical cutting machines to make copies, while others use laser-cut keys specifically designed with enhanced security features in mind.

Some of these features that come with the modern types of keys include encryption and other security mechanisms. The encryption makes it difficult for thieves to duplicate keys or open locks. Other security features to prevent theft include transponder chips that are embedded in the key to connect with your vehicle and allow it to only work when it's within a specific distance of your vehicle.

If you choose to utilize a traditional key your locksmith can make a new key with an ordinary cutter machine, which can be purchased from a variety of hardware stores. This is cheaper than using an electronic key fob or transponder key, and you'll still be able to use your locks, doors and trunk.

You could also replace your traditional keys to your car with a laser-cut version that has an unique pattern. These keys were first introduced in the 1990s and are an increasingly popular choice for those looking to protect their vehicles. Keys made of lasers are typically equipped with transponder chips programmed to only work with your vehicle. If the chips aren't present in your vehicle they will not respond to the signals sent by the key.
