Car Key Cutting Explained

Cutting a car key is more than just bending metal. It is a complicated procedure that guarantees security, function and durability of keys.

It is not uncommon to lose keys to your car or have them break through the lock. To ensure that you are able to always drive your vehicle you'll need to have a replacement key cut.

Transponder Keys

If your car was constructed in the last 20 years, it's likely to have transponder chips. These chips are small microchips inside the key's handle that transmit an electronic signal to the car's onboard computer whenever you use it. The computer onboard checks the serial number digitally of the chip prior to allowing the car to start. This prevents car thieves from taking over your vehicle, as they would need to be aware of the unique serial number.

The microchip inside your car keys transmits an unintentional radio signal to the car's receiver. The radio signal activates the microchip, which transmits an informational code to the car's onboard computer. The car will only start only if it recognizes the code. This stops the use of "hot wiring" and other methods of taking cars.

Locksmiths who provide these services can design keys for cars with chips. Some auto dealers like AutoZone offer keys with chips. They have a vast variety of keys and can assist you in choosing the appropriate one for your vehicle. They can also help you program the chip to your vehicle, which is required to use it.

Laser cut getting keys cut are more secure than flat keys. These keys feature a lock cylinder that is much harder to pick, and they can only be duplicated with expensive laser key cutting equipment or specially designed software. This technology is more prevalent in high-end vehicles, however it is now available in many affordable models of cars too.

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

VATS Keys

Before the days of transponder automobile keys made near me and cars equipped with computer chips that control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key with a resistor pellet embedded within it to verify that the correct key is being used to start the car. The VATS pellet black inside the middle of a VATS key is not a chip like those present in modern smart keys, it's simply a carbon block that is sized appropriately to have a specific electrical resistance value.

GM used 15 different resistance values for the VATS pellets and attached them to the blade of the key so that when the key is turned on in the ignition the coded signal is transmitted to the module. If the signal is in line with the one of the transistors in a VATS pellet, then the relay in starter circuit will turn on and the engine will begin to run. This does not make a car safe from burglary however it could delay a thief for at least 15 to 20 minutes.

After a lot of usage the VATS module could start to wear out. Every time a key is inserted into the ignition it moves two tiny wires within the ignition, and with time, the wires could begin to break. Once enough of the wires break then the signal to the module gets lost and it won't start the car.

You can resolve this issue at home by decoding your VATS code. It's not difficult to determine the resistance of a key using the multimeter. You can find the resistance value by putting one of the leads on the prongs made of metal on both sides of your key.

This method is also a great way to test a new key to see if it will work in your vehicle. Just be sure to remove the key from the ignition prior to testing it, or else the new key may have an incorrect VATS value and not function in your car.

Smart Key Fobs with Smart Keys

Key fobs of today do more than just unlock or start a car. They also function as used as a security device and burglar deterrent, with a lot of them incorporating advanced features that owners may not even know about. They can lock and unlock your door from a distance and make chirping sounds to aid in locating your car in a lot or summon it by pressing a button. This is more functionality than you obtain from a traditional keychain remote. Unfortunately, all that extra capabilities also means that smart key fobs may be pricier to replace than standard keychain remotes, and they usually need to be programmed by the dealer.

In fact, some dealers will charge upwards of $100 to replace one smart key fob. This is a significant amount to pay for something that spends a lot of its time snagging around in pockets and purses, where it is easily dropped, damaged, or exposed to extreme moisture and temperatures. Fortunately there are automakers who have developed ways to protect smart key fobs from the most common types of electronic threats like relay attacks. These are often utilized in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings through an untrue signal from a nearby transmitter.

To protect a smart fob, you can store it in a casing made of metal or put it in an RFID blocking case. This will prevent the transmission of these signals. However, having to take the key fob from its protective case each time you want to use it is not a good way to enjoy the benefits of the technology.

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

For most drivers, the decision to purchase a new key fob depends on the importance of your car's keyless entry and push-button start functions are. It is always advisable to keep an extra key or fob on hand in the event that you misplace yours. If you do need to purchase a new replacement, Batteries Plus has a wide selection of fobs for most cars and trucks. Additionally, we provide an easy, fast service that is roughly 50% less than you'd buy from a dealership.

Traditional Keys

The traditional car key is made of a single piece of steel with a series grooves carved into it. These grooves are made to fit certain locks. These keys will unlock your locks and start your car, assuming you don't replace them with a remote key or smart key. The only drawback of using traditional keys is that it must be physically placed into the ignition in order to start the car. If your traditional car key has been damaged or lost, you will need to visit the Gainesville Locksmith to get a new one made.

Based on the amount of time that has passed since the last time you had your keys cut, there are several different alternatives to select from when it comes time to get another copy. Some keys use mechanical cutting machines to make copies, while others employ 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 as well as other security mechanisms. Encryption ensures that only the right key is used to open your vehicle which makes it harder for thieves to duplicate keys or pick locks. Other security features that prevent theft include transponder chips that are embedded into the keys to communicate with your vehicle and allow it to only function when it's within a specific distance of your vehicle.

If you choose to utilize a traditional key your locksmith can create the new key using an ordinary cutter machine that can be bought at most hardware stores. This is less expensive than a key fob, or a transponder key cutting near me, 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-cut version with a distinctive pattern. The first time these keys were introduced was in the 1990s and are now a popular option for people who want to provide extra security to their automobiles. Laser cut keys are usually equipped with transponder chips programmed to only work with your vehicle. If these chips aren't present in your vehicle it won't respond to the signals sent by the key.
