Car Key Cutting Explained

Cutting keys for cars is more than just bending metal. It is a complicated process that guarantees security, efficiency and the longevity of keys.

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

Transponder Keys

Transponder chips will likely be added to cars that were built within the past 20 years. These microchips are in the key's handle and send a signal to your vehicle's onboard computers when you use the key. The computer on board detects the digital serial number inside the chip and allows the car to start if it's 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 in the key transmits a low-level signal the car's receiver. The radio signal activates your microchip which then transmits code to the onboard computer of the car. The car will recognize this code and only allow it to start when the key is the right one. This stops the use of "hot wiring" and other methods of taking cars.

Locksmiths that offer these services can make car keys with chips. They are also available at a few automotive stores like AutoZone. These stores offer a wide range of keys and can assist you in choosing the right one for your vehicle. They can also help you programme the chip into your vehicle, which is essential to make it work.

There are also laser cut keys, which are more secure than flat keys. These keys feature a lock cylinder that is much harder to pick, and they can only be duplicated using expensive laser key cutting machines or special software. This technology is more common in luxury vehicles, but it is now available in a wide range of low-cost cars as well.

Another type of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor on the key blade that is programmed with one of fifteen potential values to prevent them from starting a vehicle that it's not intended to. They are expensive and require the use of a key programming machine which is only available through certain locksmiths.

VATS Keys

Before transponder keys and cars that had computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a resistor pellet embedded in it to confirm that the correct key is used to start the vehicle. The VATS pellet in black in the middle of a VATS Key is not an electronic chip that is like those present on modern keys. It is simply carbon or a block that is sized to provide an electrical resistance value.

GM employed 15 different resistance values for the VATS pellets and connected them to the key's blade, so that when the key is turned on in the ignition a coded signal will be sent to the module. If the signal is in line with the signal of the transistor in a VATS pellet, then the relay in the starter circuit will be activated and the engine will start to run. This does not make a car secure from burglary, but it can delay thieves for at least 15 to 20 minutes.

After a prolonged period of usage the VATS module could begin to wear out. Each time the key is inserted into the ignition it moves two tiny wires within the ignition, and with time, the wires could begin to break. If enough wires are damaged, the signal is lost to the module and the car won't start.

The good news is that you can solve this issue yourself by decoding your own VATS key. It's not difficult to determine the resistance of a key using the multimeter. All you need to do is put one of the leads of your ohm gauge on the metal prongs that are hanging out on both sides of the key. Then read the ohm meter's display to determine the resistance value of your nearest key cutting.

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

Smart Key Fobs

Key fobs today can do more than simply unlock or start the vehicle. A lot of them come with advanced features that most owners are unaware of. They can be used as a security device or as a theft deterrent. They can remotely lock and unlock your doors, make sounding sounds to help find your car in a parking lot, or even allow you to call your vehicle by pressing the button on your smartphone. This is a lot more than you could ever imagine from a traditional keychain remote. However, all that additional functionality can mean that smart key fobs can be more expensive to replace than traditional keychain remotes. They also require programming by the dealer.

In fact, some dealers charge upwards of $100 to replace a single smart key fob. It's a high price for a product that is frequently tossed around in pockets and purses in the event that it gets damaged, dropped, or exposed to extreme temperatures and water. Fortunately, some automakers have developed ways to protect smart key fobs from the most common kinds of electronic attacks, such as relay attacks. They are typically utilized in conjunction with remote-start hacks that allow thieves to access your vehicle's settings by transmitting a fake signal from another nearby transmitter.

To secure a smart card, you can store it in a metal casing or even an RFID blocking case. This will prevent the transmission of these signals. The convenience of the technology is diminished if you must take your key fob out every time you want to take it out of the protective case.

Fortunately, some of the newer car insurance policies such as auto club memberships and extended warranty insurance policies will cover the cost of replacing a fob or reimburse you for a lost fob. You can also save money on dealership charges and get your fob cut at the hardware store or locksmith that offers key-fob cloning services.

The decision to purchase an additional fob is dependent on the significance of your car's keyless entry and start functions. You should always keep an extra key or fob in case you misplace yours. Batteries Plus offers a large range of replacement car key cutting fobs that will fit in most vehicles 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 metal with grooves cut into it to fit in a specific lock. These keys can open your locks and start your vehicle, provided that you haven't replaced them by the remote key or smart key. The only drawback of using a traditional key is that it must be physically put into the ignition to start the car. If your traditional key has been lost, damaged or stolen, you'll have to visit an Gainesville locksmith to have new keys made from the blank.

Depending on how long has passed since the last time you had your keys cut, there are several different alternatives to pick from when it comes to having another copy made. Certain keys are cut using mechanical machines or lasers, while others are cut with added security features.

Modern keys come with advanced features, such as encryption and anti-theft mechanisms. The encryption ensures that only the right key is used to start your car which makes it harder for thieves to duplicate or pick locks. Transponder chips are an additional security feature that prevents theft. They are embedded into the key and connect to 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 is able to make a new one with a standard key cutting car machine which can be purchased at many hardware stores. This is cheaper than a key fob or transponder, and you are still able to operate your trunk, locks, and doors.

Another alternative is to have the traditional car keys substituted with a laser car key cutting service near me-cut version that has a unique pattern. The first keys of this kind were released in the 1990s and are a popular option for those who wish to protect their vehicles. Laser cut keys are typically equipped with transponder chips programmed to work only with your vehicle. If the chips aren't present in your vehicle it won't respond to the signals generated by the key.
