Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece of metal. It is a complex process that guarantees security, efficiency, and longevity of the keys.

It is not unusual to lose your car key or have it break off in the lock. You'll need a replacement car key to ensure that you are able to drive your vehicle at all times.

Transponder Keys

If your car was manufactured within the past 20 years, it is likely to have transponder chips. These microchips are in the handle of the key and transmit a signal the onboard computers of your vehicle when you turn the key. The computer onboard is able to verify the digital serial number of the chip before giving the car permission to begin. This stops theft of vehicles as thieves would have to know your unique serial number to be able to take over it.

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

Car keys with chips can be created at locksmiths that offer these services. They can also be bought at a few automotive stores like AutoZone. These stores offer a wide variety of keys, and can assist you in finding the best one for your vehicle. They can even help you program the chip to your vehicle, which is necessary for it to function.

Laser cut keys are more secure than flat keys. They are more secure than traditional flat keys due to having locks that are more difficult 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 high-end cars, but it is now accessible in a variety of affordable automobiles as well.

Another type of car key that is hard to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the key blade that is programmed with one of fifteen possible values to stop the car key cutting and programming near me from starting that it's not meant to. These keys are more expensive to purchase and require a special key programming machine that is only found at some locksmiths.

VATS Keys

Before the advent of transponder keys and cars equipped with computer chips to control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses a key with a resistor embedded in it to verify that the correct key was used to start the car. The black VATS Pellet located in the middle of a VATS Key isn't a smart chip like those used on the majority of modern keys. It is simply carbon or a block which is sized to provide an electrical resistance.

GM employed 15 different resistances for the VATS Pellets and attached them to key blades in a way that, when the key is turned on, a coded message is sent to module. If the signal matches the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine begins to run. This doesn't make a car secure from burglary however it could delay thieves for at least fifteen to twenty minutes.

Unfortunately, after a long period of usage, the VATS module in your car could start to wear out. The two small wires in the ignition move each when the key is placed. As time passes, the wires may begin to break. Once enough of the wires are broken, the signal to the module is lost and it won't start the car.

The good news is that you can fix this problem yourself at home by decoding your VATS key. You'll need a multimeter and a chart to find out the resistance value of your key, but it's not that difficult. All you need 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 examine the display of your ohm meter to find out the resistance value of your key.

This is a great way to test a brand new key and check whether it will work in your vehicle. Remove the key from the ignition first before you test it. If not the key may have an incorrect VATS and will not function in your vehicle.

Smart Key Fobs for Keys

Today's key fobs can do more than unlock or start the car. They also function as used as a security device and theft deterrent, with many of them featuring advanced features that owners might not even be aware of. They can lock and unlock your door remotely, make chirping noises to help you locate your vehicle in a parking lot, or allow you to activate it by pressing the button. That's a lot more than you'd expect from the traditional keychain remote. Smart key fobs are more expensive to replace because of their extra functionality. They also need to be programmed by the dealer.

Some dealers will charge up to $100 for a single smart fob. It's a huge price for a device that's frequently tossed around in purses and pockets where it can be damaged, thrown or exposed to extreme temperatures and moisture. Fortunately there are automakers who have developed ways to protect smart key fobs from common types of electronic attacks like relay attacks. These are typically combined with a remote start hack that allows thieves access to your vehicle's settings by the transmission of a fake signal by another transmitter near.

To protect a smart fob, you can store it in a metal casing or even an RFID blocking case. This will prevent the transmission of these signals. The ease of use of this technology is diminished if you have to take your key fob out every time you take it out of the protective case.

Fortunately, some newer car-insurance policies, auto key cutting club memberships, and extended warranty insurance policies will cover the cost of replacing a fob or pay for the loss of a fob. You can also avoid paying new-car dealer fees by having your fob copied at a hardware or locksmith retailer that provides key-fob cloning.

The decision of whether to buy a new fob is largely 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 case you lose yours. And if you need to buy a new replacement, Batteries Plus has a wide selection of fobs for the majority of cars and trucks. Plus, our quick and convenient service costs about 50% less than the price you'd buy from the dealership.

Traditional Keys

Traditional keys for cars are a single piece of metal with a series of grooves cut into it to fit into a particular lock. These keys will open your locks and start your vehicle, provided that you haven't replaced them with the remote key or smart key. The only drawback to using an old-fashioned car key is that you must physically insert it into the ignition to start the engine. If your car key has been damaged or lost you'll need to visit a Gainesville Locksmith to have a new one made.

Depending on how much time has passed since you last cut your keys there are a variety of alternatives to select from when it comes to getting another copy made. Certain keys are cut with mechanical machines or lasers, while others are cut with added security features.

Modern keys are equipped with advanced features, such as encryption and anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or take locks. Transponder chips are an additional anti-theft device. They are embedded into the key and can communicate with your vehicle. This makes it only effective when you're within a certain distance.

If you decide to use a traditional, standard key, a locksmith key cutting is able to 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 using a key fob or a transponder key, and you'll still be able to operate your doors, locks and trunk.

You could also replace your traditional car keys with a laser-cut version that has an unique pattern. The first time these keys were introduced was in the late 1990s, and they're a popular choice for people who want to enhance the security of their automobiles. Laser cut keys are usually equipped with transponder chips programmed to only work with your vehicle. If these chips are not installed in your vehicle, it won't respond to the signals generated by the key.
