Car Key Cutting Explained

Car key cutting is a lot more than simply shaping the metal. It is a complex process that guarantees security, function and long-term use of keys.

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

Transponder Keys

If your car was manufactured in the past 20 years, it's likely that it has a transponder chip. These microchips are located in the handle of the key and transmit a signal to the onboard computers of your vehicle when you use the key. 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 stops thieves from taking over your vehicle since they'd need to know the unique serial number.

The microchip in the key transmits a low-level signal to the car's receiver. The radio signal activates microchip, which then transmits an encoded code to the car's onboard computer. The car will recognize this code and will only allow it to start if it is the correct one. This stops "hot wiring" or other methods of stealing cars.

Locksmiths that offer these services can create keys for cars that contain chips. They can also be purchased at certain automotive stores, such as AutoZone. These stores offer a wide variety of keys, and can assist you in choosing the appropriate one for your vehicle. They can help you program the chip in your vehicle, which is required to operate the device.

There are also laser cut car keys keys, which are more secure than conventional flat keys. These keys are more secure than flat keys because they have a lock that is harder to pick. They can only be duplicated with expensive laser key cutting machines or with specialized software. This type of technology is typically found in luxury vehicles, but it is now accessible in many affordable models of cars as well.

Another type of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. The keys contain a resistor that's black on the blade of the key. It can be programmed to any of 15 possible values to prevent it from starting a car that's not designed to. These keys are more expensive to buy and require a specific key programming machine that can only be found at a few locksmiths.

VATS Keys

Before the advent of transponder keys and cars equipped with computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with a resistor embedded in it to confirm that the right key was used to start the car. The VATS pellet in black that is located in the middle of the VATS Key is not an electronic chip that is like those used on the majority of modern keys. It is merely carbon or a block which is sized to have an electrical resistance.

GM used 15 different resistance values for VATS pellets and attached them to the key's blade, so that when the key is turned in the ignition the coded signal is sent to the module. If the signal is in line with that of the transistor in a VATS pellet then the relay in starter circuit will activate and the engine will begin to run. This doesn't make a vehicle theft proof however it can delay the theft by at most 15 to 20 minutes.

Unfortunately, after a significant amount of use, the VATS module in your car could begin to wear out. Each time a key is inserted into the ignition, it reroutes two small wires within the ignition, and with time, the wires can start to break. When enough wires have been broken the signal is lost to the module and the car won't begin.

You can solve this problem at home yourself by decoding your VATS key. You'll require a multimeter and an indicator chart to determine the resistance value of your key, but it's not difficult at all. All you need to do is put one of the leads of your ohm meter on the prongs of metal that are hanging out on both sides of the key, and then examine the display of your ohm meter to determine the resistance value of your key.

This is a great opportunity to test a brand new key and see whether it will work in your car. Make sure you remove the key from the ignition before you begin testing it, otherwise the new key may have an incorrect VATS number and will not function in your car.

Smart Key Fobs

Key fobs today do more than simply unlock and start the vehicle. They also function as an alarm system and a theft deterrent, with many of them having advanced features that the owners might not even be aware of. They can lock and unlock your door [empty] remotely and make chirping sounds to assist you in finding your vehicle in a parking lot or summon it by pressing the button. This is more than you could ever expect from the traditional keychain remote. Smart key fobs are more expensive to replace due their extra functions. They also have to be programmed by the dealer.

It's a huge cost to pay for a product that is often jostled in purses and pockets where it could be damaged, dropped, or exposed to extreme temperatures and humidity. Some automakers have developed methods to protect smart key fobs from common electronic threats, including relay attacks. They are typically utilized in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings by transmitting an untrue signal from a nearby transmitter.

To secure a smart card you can put it in a metal case or even an RFID blocking case. This will block the transmission of these signals. The convenience of the technology is compromised if you need to remove your key fob every time you take it out of the protective case.

Fortunately, some of the newer car insurance policies and auto club memberships and extended warranty coverage will cover the cost of a replacement or reimburse you for a lost fob. You can also avoid paying new-car dealership fees by having your fob copied at a hardware or locksmith store that offers key-fob-cloning services.

The decision of whether to purchase a new fob is largely dependent on the importance of your car's keyless start and entry functions. In any case it is advisable to keep a spare fob or key in case you lose it. Batteries Plus offers a large range of replacement fobs that fit in most vehicles and trucks.

Traditional Keys

These keys can open your locks and begin your car, assuming you haven't replaced them with the remote key or smart key. The only disadvantage of using an old-fashioned car key is that you must physically insert it into the ignition to start the engine. If your traditional key has been lost, damaged or stolen, you'll need to visit the Gainesville locksmith to have new keys made from the blank.

Based on the amount of time that has passed since you last had your keys cut there are a variety of options available for you to select from when it comes time to get another copy made. 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 modern features that come with modern types of keys include encryption and other anti-theft mechanisms. Encryption ensures that only the right key is used to start your vehicle making it much more difficult for thieves to duplicate keys or pick locks. Other security features to prevent theft include transponder chips that are embedded in the key to communicate with your vehicle and allow it to work only when it's within the distance of your car.

If you choose to use a traditional, standard key, a locksmith could create a new one with a standard key cutting machine that can be found at many hardware stores. This is less expensive than a key fob or a transponder, and you are still able to operate your locks, trunk and doors.
