Car Key Cutting Explained

Cutting a car key is more than just bending a piece metal. It is a complex procedure that ensures security, functionality, and longevity of the keys.

It is not uncommon to lose your car keys or even break it in the lock. To ensure you're able to always drive your vehicle you'll require a replacement key cut.

Transponder Keys

If your car was built in the last 20 years, it is likely that it has a transponder chip. These chips are tiny microchips inside the key's handle that send a signal to the vehicle's onboard computer when you are using it. The onboard computer reads the digital serial number in the chip and only allows the car to start if it is the correct one. This helps prevent theft of cars since thieves need to know your unique serial number in order to be able to take over it.

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

Locksmiths that offer these services can design car keys with chips. Some auto dealers like AutoZone sell them. They have a huge variety of keys, and can assist you in choosing the appropriate one for your vehicle. They can even help you program the chip to your vehicle, cedrus.market which is essential to make it work.

There are also laser cut keys, which are more secure than flat keys. These keys feature an cylinder for locking that is much more difficult to pick, and they can only be duplicated using expensive laser key cutting equipment or specialized software. This technology is most commonly found in high-end vehicles but is now accessible on many affordable models.

Another kind of car key that's hard to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor on the key blade that is programmed with one of fifteen possible values to prevent them from starting a vehicle that it's not meant to. These keys are costly and require the use of a key programming machine which is only available through certain locksmiths.

Keys to VATS

Before transponder keys and 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 regular key with a pellet of resistance embedded in it to confirm that the correct key is being used to start the car. The VATS pellet that is black in the middle of a VATS Key is not an electronic chip that is like those present on 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 connected them to the blade of the key to ensure that, when the key is turned in the ignition, a coded signal is transmitted to the module. If the signal matches the one of the transistors in a VATS pellet, then the relay in starter circuit will activate and the engine will start to run. This doesn't make a car burglar-proof, but it can delay thieves for at least 15 to twenty minutes.

After a lot of usage the VATS module may start to wear out. Each time a key is inserted into the ignition, it reroutes two small wires within the ignition, and over time the wires may start to break. When enough wires break, the signal to the module gets lost and the module won't be able to start the car.

The good news is that you can solve this issue at home by decoding your VATS key. You'll require a multimeter and a chart to find out the resistance value of your key, but it is not that difficult. You can determine the resistance value by placing one of the leads on the prongs made of metal on both sides of your key.

This method is also a good way to test a new key to see whether it will work in your vehicle. Just be sure to remove the key from the ignition prior to testing it, or else the new key may have an incorrect VATS value and not function in your car.

Smart Key Fobs with Smart Keys

Key fobs today are more than just unlock or start the vehicle. They are also an alarm system and a security measure against theft, with many of them featuring advanced features that owners may not even be aware of. They can lock and unlock your door remotely, make chirping noises to aid in locating your vehicle in a parking lot, or allow you to summon it by pressing a button. This is more functionality than you can get from a traditional keychain remote. Unfortunately, all that extra capabilities can mean that smart key fobs can be more expensive to replace than traditional keychain remotes, and they usually need to be programmed 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 often tossed around in purses and pockets where it can be damaged, dropped or exposed to extreme temperatures and moisture. Fortunately there are automakers who have developed ways to safeguard smart key fobs from common types of electronic threats like relay attacks. These are typically combined with remote start hacks that allows thieves access to your vehicle's settings through the transmission of a fake signal from another transmitter nearby.

To secure a smart card you can put it in a casing made of metal or even an RFID blocking case. This will stop the transmission of these signals. The convenience of this technology is diminished if you have to remove your key fob each time you want to use it from the protective case.

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

For most drivers who want to buy an additional key fob is contingent on how crucial your car's keyless entry and push-button start functions are. In any event you should have an extra fob or key in case in case you lose it. Batteries Plus offers a large selection of replacement fobs that will fit most cars and trucks. Plus, our quick and efficient service is 50% less than what you would buy from a dealership.

Traditional Keys

The car key of old is one piece of metal with a series of grooves carved into it. These grooves are made to fit specific locks. They can open your locks and begin your car, provided you haven't replaced them by an electronic key or a remote key. The only downside of using an old-fashioned car key is that you need to 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 get new keys made from the blank.

Based on the amount of time that has passed since you last had your keys cut, there are several different alternatives to select from when it comes time to get another copy made. Certain keys are cut with mechanical machines or lasers, while others are cut with security features that are enhanced.

Some of these modern features that come with modern keys include encryption as well as other anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or take locks. Transponder chips are another anti-theft device. They are embedded in the key and connect to your vehicle. This means that they only work only when you're within certain distance.

If you choose to use a traditional standard key, a locksmith can create a new one using a standard key cutter machine, which is available at most hardware stores. This is less expensive than a key fob, or a transponder, and you are still able to operate your trunk, locks, 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 1990s and are a popular option for those looking to protect their vehicles. Laser cut keys are usually equipped with transponder chips that are programmed to work only with your vehicle. If these chips are not present in your vehicle, it will not respond to the signals generated by the key.
