Car Key Cutting Explained

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

It is not uncommon to lose your car keys or even have it break in the lock. You will need a new car key in order to ensure you can drive your car at all times.

Transponder Keys

Transponder chips will likely be fitted in vehicles that were built in the last 20 years. These microchips are located in the key's handle and transmit a signal to the onboard computers of your vehicle when you press the key cutting car. The computer onboard checks the serial number of the chip prior to allowing the car to begin. This prevents car theft as thieves would have to know your unique serial number to have a chance at hijacking it.

The microchip inside your car key transmits an low-level radio signal to the receiver inside the car. The radio signal activates your microchip that then transmits the instructions to the onboard computer of the car. The car will only begin if it recognizes this code. This stops the use of "hot wiring" and other methods of stealing cars.

Car keys with chips can be created at an authorized locksmith who offers these services. Some auto dealers like AutoZone offer them. Those stores carry a huge selection of keys and can assist you in selecting the best one for spare your vehicle. They can even assist you to program the chip to your vehicle, which is essential to make it work.

You can also purchase laser cut keys, which are more secure than flat keys. These keys are more secure than flat keys due to having locks that are more difficult to pick. They can only be duplicated using expensive laser key cutting machines or with specialized software. This technology is most common in high-end vehicles but is now accessible on a variety of affordable models.

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

Keys to VATS

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

GM used 15 different resistance values for VATS pellets and connected the key's blade, so that when the key is turned on in the ignition, a coded signal is sent to the module. If the signal matches the signal of the transistor in a VATS pellet, then the relay in the 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 theft by at least 15 to 20 minutes.

After a lot of usage the VATS module may begin to wear out. The two small wires in the ignition are moved every when the key is introduced. Over time the wires could start to break. Once enough of the wires are broken, the signal to the module gets lost and the module won't be able to start the car.

The good news is that you can solve this issue at home by decoding your VATS key. It's not hard to determine the resistance of a key using the multimeter. All you have to do is put one of the leads of your ohm meter on the prongs of metal that are sticking out on both sides of the key. Then examine the display of your ohm meter to determine the resistance value of your key.

This is a great way to test a new key and check whether it works in your car. Remove the key from the ignition first before you test it. In the event that it is not removed, the key may have an incorrect VATS, and will not function in your vehicle.

Smart Key Fobs with Smart Keys

Today's key fobs are more than just a way to unlock or start the car. They often have advanced features that a lot of owners are not aware of. They can be employed as a security tool or as a theft deterrent. They can lock and unlock your door remotely and emit chirping sounds to aid in locating your vehicle in a parking lot or summon it by pressing a button. This is more features than you obtain from a traditional keychain remote. Smart key fobs are more expensive to replace because of their extra functions. They also need to be programmed by a dealer.

In fact, some dealers charge upwards of $100 to replace one smart key fob. That's a huge sum to pay for something that spends a lot of its time in pockets and purses, which is where it's easily dropped, damaged, or exposed to moisture and extreme temperatures. Fortunately certain automakers have come up with ways to safeguard smart key fobs from the most common types of electronic threats like relay attacks. They are usually paired with a remote start hack that allows thieves access to your vehicle's settings via the transmission of a fake signal from another transmitter close to.

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

Some of the newer policies, such as auto club memberships or extended warranties will cover the cost of a replacement fob or reimburse you in the event that it's lost. You can also avoid paying dealership fees by having your fob copied by a locksmith or hardware store that offers key-fob-cloning services.

The decision to purchase an additional fob is dependent on the significance of your car's keyless start and entry functions. In any event, you should always have a spare fob or key in case you lose yours. Batteries Plus offers a large choice of replacement fobs that fit on most cars and trucks. We also offer an efficient, quick service that is approximately 50% less than you'd spend at the dealership.

Traditional Keys

Traditional keys for cars are a single length of metal that has a series of grooves cut into it to fit in a specific lock. They can unlock your locks and start your car, provided you don't replace them with a remote key or smart key. The only drawback to using a traditional car key is that you have to physically insert it into the ignition to start the engine. If your traditional key is lost, broken or stolen, you'll have to visit a Gainesville locksmith to get a new one made from the blank.

There are several options to select from based on how long it has been since you were able to cut your keys. Certain keys employ mechanical cutting machines to produce copies, while others employ laser-cut keys that have been specifically designed with enhanced security features in mind.

Modern keys have advanced features like encryption and anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or open locks. Transponder chips are another anti-theft device. They are embedded in the key and communicate with your vehicle. This makes it only effective only when you're within certain distance.

If you choose to use a conventional, standard key, a locksmith could make a new one using a standard key cutter machine which can be purchased at the majority of hardware stores. This is less expensive than a key fob or a transponder key, and you'll still be able to operate your locks, doors and trunk.

You could also replace your traditional car keys with a laser-cut version with a distinctive pattern. These keys first came out in the 1990s, and are a popular choice for those looking to enhance the security of their automobiles. Laser cut keys typically 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 transmitted by the key.
