Car Key Cutting Explained
Cutting a car key is more than just bending a piece metal. It is a complex process that ensures security, functionality and long-term use of keys.
It is not unusual to lose your car key or have it break off in the lock. To ensure you're able to always drive your vehicle, you will require a replacement key cut.
Transponder Keys
If your car was constructed within the last 20 years, it's likely to have a transponder chip. These microchips are tiny inside the handle of your key which transmit a signal to the vehicle's onboard computer whenever you use it. you can check here in the car scans the digital serial numbers in the chip and only allows the car to start if it's the correct one. This prevents car theft since thieves need to know your unique serial number in order to have a chance at hijacking it.
The microchip in your car key transmits an low-level radio signal to the receiver inside the car. The radio signal activates your microchip which then transmits code to the computer onboard of the car. The car will only start when it recognizes the code. This prevents the use of "hot wiring" and other methods of taking cars.
Locksmiths who provide these services can design keys for cars that contain chips. Some auto dealers like AutoZone offer keys with chips. These stores have a large range of keys and can assist you in finding the right one for your car. They can assist you in programming your vehicle's chip which is needed to use the device.
Laser cut keys are more secure than flat keys. These keys feature the lock cylinder, which is much more difficult to pick, and can only be duplicated using expensive laser key cutting equipment or specialized software. This technology is more common in high-end cars, but it is now accessible in a variety of affordable cars too.
The VATS (vehicle-anti-theft system) key is a different type of key that's difficult to duplicate. These keys have a black 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 designed to. These keys are more expensive to purchase and require a special key programming machine that can only be located at certain locksmiths.
Keys to VATS
Before transponder keys or cars that had computers built-in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS makes use of a key with an internal resistor to confirm that the right key was used to start the car. The black VATS pellet inside the middle of the VATS key isn't an electronic chip like the ones present in modern smart keys, it's simply a carbon block appropriately sized to have an electrical resistance that is specific to.
GM used 15 different resistances for VATS pellets and connected the key blades to them so that when the key was turned in the ignition a coded message is sent to module. If the signal is in line with the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine starts to run. This doesn't make a car secure from burglary, but it can delay the thief for a minimum of 15 to twenty minutes.
After a lot of usage the VATS module may start to wear out. The two small wires in the ignition are moved each time the key is introduced. Over time, the wires may begin to break. Once enough wires are broken the signal goes out to the module and the car will not start.
The good news is that you can fix this issue at home by decoding your own VATS key. It's not difficult to determine the resistance value of a key by using a multimeter. All you have to do is place one of the leads of your ohm gauge on the prongs made of metal sticking out on both sides of the key, then read the ohm meter's display to find out the resistance of your key.
This can also be a good method to test a new key to determine if it will work in your car. Remove the ignition key first before you test it. Otherwise the key may have an incorrect VATS and will not function in your vehicle.
Smart Key Fobs for Keys
Key fobs today can do more than just unlock or start the car. A lot of them come with advanced features that many owners are not aware of. They can be used as a security device or as a theft deterrent. They can lock and unlock your door remotely and make chirping sounds to aid in locating your vehicle when you're in a hurry, or allow you to activate it by pressing the button. This is a lot more than you'd think of from a standard keychain remote. Unfortunately, all that added functionality also means that smart key fobs can be more expensive to replace than traditional keychain remotes. They also need to be programmed by the dealer.
Some dealers charge up to $100 for one smart fob. It's a steep price to pay for a device that is often jostled in purses and pockets in the event that it gets damaged, dropped or exposed to extreme temperatures and humidity. Some automakers have developed methods to shield smart key fobs from common electronic threats, including 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 safeguard a smart fob to protect it, you can place it in a casing made of metal or put it in an RFID blocking case. This will block the transmission of these signals. The convenience of this technology is diminished if you have to take your key fob out every time you want to take it out of the protective case.
Fortunately, a few of the latest car insurance policies such as auto club memberships and extended warranty coverage will cover the cost of a replacement or pay for the loss of a fob. You can also avoid paying new-car dealership fees by having your fob cloned by a locksmith or hardware retailer that provides key-fob cloning.
The decision to buy a new fob is dependent on the significance of your car's keyless entry and start functions. It is always advisable to keep an extra key or fob on hand in the event that you misplace yours. Batteries Plus offers a large choice of replacement fobs that will fit on most cars and trucks. Plus, our quick and convenient service costs about 50% less than what you'd spend at the dealership.
Traditional Keys
The classic car key is one piece of metal with a series grooves carved into it. These grooves are designed to fit certain locks. They can unlock your locks and start the car, provided you haven't changed them out for a smart key or remote key. The only drawback to using the traditional car key is that you need to physically insert it into the ignition to start the engine. If your car key is lost or broken it is necessary to visit the Gainesville Locksmith to get a new one created.
You have a few options to choose from depending on how long it has been since you cut your keys. Certain keys employ mechanical cutting machines to make copies, while others employ laser-cut keys that have been specifically designed with enhanced security features in mind.
Some of these advanced features that come with modern-day keys include encryption and other anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or pick locks. Transponder chips are an additional anti-theft feature. They are embedded in the key and can communicate with your vehicle. This makes it only work when you're within a certain distance.
If you opt to use a traditional, standard key, a locksmith can create a new key with a standard key cutting machine which can be purchased at most hardware stores. This is cheaper than using the key fob or transponder key, and you'll be able to use your locks, doors and trunk.
Another alternative is to get your standard car key substituted with a laser-cut version with a unique pattern. The first keys of this kind were released in the 1990s and are a popular option for those who want to protect their vehicles. Laser cut keys typically contain transponder chips that are programmed to work only for your specific vehicle. If these chips aren't present in your vehicle they will not respond to the signals generated by the key.
