A Peek Inside Cut Car Key's Secrets Of Cut Car Key
Car Key Cutting Explained

Car key cutting is much more than just shaping a piece of metal. It is a complicated procedure that ensures safety, functionality and durability of keys.

It is not uncommon to lose keys to your car or even have them break into the lock. To ensure that keys cut for cars are able to always drive your car, you will need a new key cut.

Transponder Keys

Transponder chips are likely to be installed in cars that were built in the last 20 years. These chips are tiny microchips in the handle of your key that transmit signals to the car's onboard computer when you use it. The computer in the car scans the digital serial numbers within the chip and allows the car to start if it's the correct one. This prevents thieves from stealing your car, as they would need to be aware of the unique serial number.

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

Locksmiths who provide these services can create keys for cars that contain chips. Some auto dealers like AutoZone sell keys with chips. They have a huge variety of keys, and can assist you in finding the appropriate one for your vehicle. They can help you program the chip in your vehicle that is required for the device to function.

Laser cut keys are more secure than flat keys. These keys have an cylinder for locking that is much more difficult to pick, and they can only be duplicated using expensive laser key cutting machines or special software. This technology is most common in high-end cars, but is now available on a variety of affordable models.

Another type of car key that's difficult 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 stop them from starting a car that it's not intended to. These keys are more expensive to purchase and require a special key programming machine that can only be found at some locksmiths.

Keys to VATS

Before transponder keys and cars with computer chips built in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS uses a key with an embedded resistor to verify that the correct key was used to start the car. The VATS black pellet that is located in the middle of a VATS key is not an electronic chip as found on modern smart keys. It is simply a piece of carbon appropriately sized to have an electrical resistance that is specific to.

GM employed 15 different resistance values for the VATS pellets and attached them to the blade of the key so that when the key is turned in the ignition the coded signal is transmitted to the module. If the signal matches the signal 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 car secure from burglary, but it can delay thieves for at least 15 to 20 minutes.

After a long period of use the VATS module could begin to wear out. Each time a key is inserted into the ignition, it moves two tiny wires within the ignition, and over time the wires could start to break. If enough wires are damaged, the signal is lost to the module and the car will not start.

You can solve this issue at home by decoding your VATS key. It's not difficult to determine the resistance of a key with a multimeter. All you have to do is place one of the leads of your ohm gauge on the prongs of metal that are hanging out on both sides of the key, then read the ohm meter's display to find out the resistance of your key.

This is a great way to test out a new key and determine whether it will work in your car. Be sure to remove the key from the ignition prior to testing it, as the new key may have an incorrect VATS number and will not work in your vehicle.

Smart Key Fobs for Keys

Key fobs today do more than simply unlock and start the car. A lot of them come with advanced features that most owners aren't aware of. They can be used as a security gadget or as a theft deterrent. They can lock and unlock your door from a distance and make chirping sounds to help you locate your car in a lot, or allow you to activate it by pressing a button. That's a lot more than you could ever think of from a standard keychain remote. Smart key fobs are more expensive to replace because of their extra functionality. They also have to be programmed by a dealer.

Some dealers charge up to $100 for one smart fob. It's a steep price for a device that is often tossed around in purses and pockets in the event that it gets damaged, dropped or exposed to extreme temperatures and moisture. Certain automakers have developed strategies to protect smart key fobs from common electronic attacks, such as relay attacks. These are often combined with remote start hacks that gives thieves access to your vehicle's settings through the transmission of a fake signal by another transmitter near.

One method to safeguard the smart key fob is to put it in a metal case or use a dedicated RFID blocking case that prevents the transmission of these signals. The ease of use of this technology is compromised if have to remove your key fob each time you want to use it from the protective case.

Certain policies that are more recent like auto club memberships as well as extended warranties will cover the cost of replacing the fob, or reimburse you if it's lost. You can also save money on new car dealership charges and get your fob cut at a hardware store or locksmith which offers key-fob cloning.

The decision of whether to buy a new fob is largely dependent on the importance of your car's keyless entry and start functions. Always keep an extra key or fob on hand in case you lose yours. Batteries Plus offers a large selection of replacement fobs that fit on most cars and trucks. Plus, our quick and easy service is about 50% less than what you'd buy from the dealership.

Traditional Keys

The car key of old is a single piece of metal with a series of grooves cut into it. These grooves are made to fit certain locks. These keys can unlock your locks and start your car, provided you don't replace them with an electronic key or a remote key. The only drawback of using the traditional key is that it has to be physically put into the ignition in order to start the vehicle. If your traditional car key has been damaged or lost, you will need to visit an Gainesville Locksmith to get a new one created.

Depending on how long has passed since you last had your keys cut, there are several different options available for you to pick from when it comes to getting another copy made. Certain keys are cut with mechanical machines and others are laser-cut with security features that are enhanced.


Some of these modern features that are included in modern-day keys include encryption as well as other security mechanisms. Encryption makes it harder for thieves to duplicate keys or take locks. Other security features that prevent theft include transponder chips that are embedded into the keys to communicate with your car and make it work only when it's within a specific distance of your car.

If you choose to use a traditional key, your locksmith can make a new key with an ordinary cutter machine that is available from a variety of hardware stores. This is less expensive than a key fob, or a transponder. you can still operate your locks, trunk, and doors.

You could also replace your traditional keys for your car with a laser cut version that has an unique pattern. These keys were introduced in the early 1990s and are an increasingly popular choice for those who wish to safeguard their vehicles. Laser cut keys are typically equipped with transponder chip that is programmed to only work with your vehicle. If the chips aren't present in your vehicle it won't respond to the signals transmitted by the key.
