Car Key Cutting Explained

Cutting keys for cars is more than just bending metal. It is a complicated procedure that ensures safety, functionality and long-term use of the keys.

It is not uncommon to lose your car keys or even break it in the lock. You'll require a replacement car key to ensure that you are able to drive your car at all times.

Transponder Keys

If your car was built within the last 20 years, it's likely that it has transponder chips. These microchips are located in the key's handle and send a signal to the onboard computers in your vehicle when you use the key. The computer on board scans the digital serial numbers inside the chip and allows the car to start if it's the right one. This prevents thieves from taking over your vehicle since they'd need to know the unique serial number.

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

Locksmiths that offer these services can create keys for cars with chips. Some car dealers, like AutoZone offer keys with chips. These stores have a wide selection of keys and can help you get the right one for your car. They can also help you program the chip to your vehicle, which is required to make it work.

There are also laser cut keys that are more secure than flat keys. These keys feature an cylinder for locking that is more difficult to pick, and they are only duplicated using expensive laser key cutting equipment or specially designed software. This technology is more prevalent in high-end cars, but it is now available in a variety of affordable automobiles as well.

The VATS (vehicle-anti-theft system), local key cutting is another 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 fifteen potential values to prevent the car from starting that it's not intended to. They are expensive and require an instrument for programming keys, which is only available at a few locksmiths.

VATS Keys

Before transponder keys cut near me now or cars with computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an internal resistor to confirm that the right key was used to start the car. The VATS pellet in black in the middle of a VATS Key isn't an electronic chip that is like those used on the majority of modern keys. It is merely carbon or a block that is sized to have an electrical resistance value.

GM used 15 different resistance values for 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 sent to the 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 starts to run. This doesn't make a car safe from theft however it can delay the thief by at most 15 to 20 minutes.

After a prolonged period of usage the VATS module may start to wear out. The two wires that connect the ignition move each time a key is inserted. As time passes the wires can begin to break. When enough wires are broken the signal to the module gets not received and it will not start the car.

The good news is that you can solve this issue at home by decoding your own VATS key. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it is not difficult at all. All you need to do is put one of the leads of your ohm gauge on the prongs of metal that are visible on both sides of the key, and then read the ohm meter's display to find out the resistance value of your key.

This is a great opportunity to test a new key and determine whether it works in your car. Remove the key from the ignition first before you test it. If not, the key may have an incorrect VATS and not work in your vehicle.

Smart Key Fobs with Smart Keys

Key fobs today do more than simply unlock or start the car. They also function as a security device and a security measure against theft, with many of them featuring advanced features that owners may not be aware of. They can lock and unlock your door remotely and emit chirping sounds to aid in locating your vehicle in a parking lot, or allow you to activate it by pressing a button. That's a lot more than you'd imagine from a traditional keychain remote. Unfortunately, all that extra features also means that smart key fobs could be pricier to replace than traditional keychain remotes, and they usually require programming by the dealer.

Some dealers charge up to $100 for one smart fob. It's a high cost to pay for a product that is frequently tossed around in pockets and purses 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. These are usually utilized in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings through a fake signal from another nearby transmitter.

One method of protecting the key fob's RFID is to keep it in a metal case or a specially designed RFID blocking case that blocks the transmission of these signals. The ease of use of this technology is compromised if you have to remove your key fob each time you need to use it from the case.

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

The decision to buy an additional fob is dependent on the significance of your car's keyless start and entry functions. In any event it is advisable to keep an extra key or fob handy just in case you lose it. If you have to buy a new replacement, Batteries Plus has a wide selection of fobs for the majority of cars and trucks.

Traditional Keys

These keys can open your locks and begin your car, assuming you don't replace them with an electronic key or a remote key. The only disadvantage of using traditional keys is that it has to be physically inserted into the ignition in order to start the vehicle. If your traditional car key is lost or broken you'll need to visit an Gainesville Locksmith to get a new one created.

Based on the amount of time that has passed since you last had your keys cut, there are several different options to pick from when it comes to having another copy made. Certain keys are cut with mechanical machines, while others are laser-cut with added security features.

Modern keys cut in my area have advanced features such as encryption and anti-theft mechanisms. The encryption ensures that only the right key can be used to start your vehicle making it much more difficult for thieves to duplicate or pick locks. Other anti-theft features include transponder chips, which are embedded into the keys to connect with your vehicle and allow it to only function when it's within a certain distance of your vehicle.

If you choose to use a traditional, standard key, a locksmith could create a new key using a standard key cutter machine which can be purchased at many 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 to your car with a laser-cut version with a distinctive pattern. These keys were first introduced in the 1990s and have become a popular option for those who want to secure their vehicles. Laser cut keys typically come with transponder chips that are programmed to work only for your specific vehicle.
