Types of Ignition Key Replacement The most basic type of car key is the blade that you insert into an ignition lock cylinder in order to start your car. Older cars have these kinds of keys however modern models incorporate transponder chips inside the keys, which must be programmed to work with the car. It is common to replace these keys at a dealership or an automotive locksmith. They can provide an replacement with your car's VIN number. Transponder Keys Transponder chips can be found in vehicles manufactured within the last 20-years. This technology is a perfect combination of mechanical and electronic security, and it works by sending a coded signal to the vehicle every time you put the key in the ignition. The engine control unit compares this code against its own database to determine if you're the owner of the vehicle who is authorized. If you are then, the car will start. The process is completely invisible and takes milliseconds. You will see a small chip on the front of your key, if you've got a transponder. The most efficient way to test it is to insert the key into your ignition and then turn it on. If your car responds to the keys it means it has been programmed and confirmed as an authentic transponder. The reason for this additional layer of security is because while traditional keys rely on matching the lock tumblers transponder chips actually transmit an electronic signal to the car's computer. This prevents people from hot-wiring their vehicles by ensuring that the right key is used. To reprogram a transponder device you must follow some simple instructions. First, make sure that the key functions and then put it aside. Then, you can insert the blank key into the ignition and turn the key to the “on” position. Leave it there for about 15 minutes, and then turn the ignition off. After 15 minutes, you can then try to start the car again. If it isn't starting then you'll need to repeat the procedure of turning off and on the car. The process of reprogramming the transponder key is more complicated and expensive than duplicating a standard mechanical car key. It is also necessary to cut your key professionally and a key programmer is required to take the code and match it to a transponder that is new. Smart Keys Smart keys enable drivers to unlock doors and start their engines by pressing a button without the need to put the key in the ignition. Inside the fob is a transponder chip that communicates with the vehicle's immobilizer and disarms it to allow the car to start. The fob comes with remote control buttons that open the tailgate, unlock the trunk and operate the door locks. Some include a panic switch that, when pressed blasts the horn of the vehicle in order to scare away thieves. Like all technologies, smart keys have advantages and disadvantages. They do provide increased security and ease of use – particularly for those with an inclination to not lock their car. These features also can save you money over the long term.

They have an electronic chip embedded in the head of the key that communicates with a receiver in the vehicle and allows it to start only when the correct code is sent. This kind of key has been very effective in reducing theft from vehicles and the process of programming a new key and transponder is quite simple for a professional car locksmith. Another kind of key is the flip-style, which tucks the key blade inside an enclosure when not in use. This helps to protect the blade from damage, and also reduces bulk for more convenient carrying. The key fob component of this kind of key usually has remote control functions, allowing drivers to lock and unlock trunk or car doors, and start the engine remotely. Laser cut keys are readily available for those looking to add an additional layer of protection against auto theft. Lasers are used to cut the shanks of these keys, creating a pattern that is more difficult to duplicate. Although these keys are more expensive than standard keys and key fobs but they also provide an increased level of security against theft by unauthorized users. Additionally, there are switchblade keys, which resemble the bladed weapons that helped popularize the term “switchblade.” These keys fold into the shape of a key fob handle when not in use. The handle opens when a button is pressed, revealing the blade of the key. Locksmiths can replace the key blade or key fob portion of this kind of key, but they can be a bit more costly than basic replacements. Smart keys are the latest advancement in security for vehicles. They provide a completely electronic system for unlocking and opening your car. G28 Car Keys communicate with your vehicle via antennas embedded in the car frame and body.

This stops old codes from being re-used and makes keys stolen from the car useless to thieves. Key fobs can also be used as a backup option to unlock and start the car if the key is somehow lost.
