Types of Ignition Key Replacement The car key with a blade is the easiest to use. It's as simple as inserting it into the ignition lock cylinder, and you're ready to go. These keys are used in older cars, however the newer models have transponder chips which must be programmed into the car in order to work. The keys can be replaced by a dealer or an automotive locksmith. They can create a replacement using your car's VIN number. Transponder Keys If your car was built in the past 20 years, it's an absolute guarantee that it has a transponder chip embedded inside. This technology is a perfect blend of electronic and mechanical security. It works by sending a coded signal to the vehicle every time you put the key in the ignition. The engine control unit examines this code against its own database to determine if you are the authorized owner of the vehicle. If you are then, the car will start. The process takes place in milliseconds, and is not visible to the naked eye. If you have a transponder key, you'll be able see tiny electronic chips on the face of your key. Inserting the key into your ignition and turning it on is the most efficient method to test. If your car responds, it means that the key has been programmed and successfully verified as an authentic transponder key. This is because, whereas traditional keys work with lock tumblers to unlock the vehicle, transponder chips transmit an electronic signal directly to the computer. This helps prevent people from hot-wiring their cars by ensuring that the right key is used to activate the ignition system. Follow these easy steps to reprogram a transponder. First, ensure that the key is in working condition and then put it aside. Next, sit in G28 Car Keys and insert the new key blank into the ignition, turning it to the off position. It should remain there for around 15 minutes, then turn off the ignition. After 15 minutes, you can attempt to start the car once more. If it doesn't start, then you will need to repeat the procedure of turning off and on the car. Reprogramming transponder keys is more complicated and expensive than duplicating a standard mechanical car key. In addition, you'll require the key cut professionally and a car key programming device is needed to extract the code from your ECM and then match it to the new transponder key. Smart Keys With smart keys, drivers can open their doors and start the engine by simply pressing a button without having to insert the key into the ignition. Inside the fob is a transponder chip that communicates with the immobilizer of the car and disarms it to allow the car to start. The fob typically has remote control buttons that control the door locks, unlock the trunk and open the tailgates. Some include a panic switch that, when pressed blasts the horn of the vehicle to scare away intruders. Smart keys aren't any different. They come with their advantages and disadvantages, just like every other technology. They do provide increased security and ease of use – particularly for those with a tendency to forget to lock the car. These features can help you save money over time. Smart keys are not only an excellent way to stop thieves from stealing cars and other valuables, but they also aid you in avoiding the infamous phrase, “it's somewhere in here.” Instead of using a traditional metal key shaft, smart keys communicate with your car via radio frequency signals. They are not duplicated using a traditional key. This does not mean that you can't find the key in case it is lost. Depending on the manufacturer, smart keys may be more expensive than traditional groove cut keys, depending on the manufacturer. This is because they are equipped with electronic components, making them more complex and difficult to repair if something goes wrong. Pop-A Lock can replace and program smart keys at a fraction of what dealerships charge. We can complete the process in a shorter amount of time, saving you from having to arrange alternative transportation while your vehicle is being repaired. If you're thinking about getting a smart key for your car, do yourself a favour and buy a spare fob to keep in a secure place, or invest in motor insurance that will have a large payment in case you lose your keys. Keep it out of the people's eyes. Low frequency transmissions allow someone to steal your car. Switchblade Keys There are a variety of options when it comes to replacing the ignition key. The traditional key is the most common one, and has a steel shaft that has distinct notches or cutouts which correspond to lock tumblers in the ignition cylinder and door. They lack advanced features like remote unlocking or keyless entry, but they are reliable and easy to use. Transponder keys, on other hand, are an enormous leap forward in the field of automotive security technology. These keys have an electronic chip embedded in the head of the key that communicates with a receiver inside the vehicle that allows it to begin only if the correct code is sent. This type of key has proven effective in reducing the theft of vehicles, and the process of programming a new key with a transponder is fairly simple for a professional locksmith for cars. Another kind of key is the flip-style key that is designed to tuck the key blade inside a housing when not in use. This protects the blade of the key from being damaged, and makes it easier to carry. This kind of key comes with an accessory key fob that has remote control features. Drivers can lock and unlock car trunks, doors, and start their engines from a distance. Laser cut keys are offered to those who want to add an extra layer of security against auto theft. Lasers are used to cut the shanks of these keys, forming patterns that are difficult to duplicate. These keys are more expensive than traditional keys and key fobs but they provide a higher level of security. Finally, there are switchblade keys that resemble the bladed weapons that popularized the term “switchblade.” These keys fold into a key fob handle when they are not being used. When the user presses a button the handle opens and exposes the key blade as a switchblade knife would. Locksmiths can replace the key blade or the key fob part of this type of key, but they are slightly more expensive than standard replacements. Smart keys are the most recent technology in security for cars. They are a fully electronic system for unlocking and launching your car. The keys communicate with your vehicle via antennas that are inserted into the car's body and frame, eliminating the requirement for a traditional blade, and the need to physically insert the key into the ignition cylinder. Some of the most advanced models can even lock and start the car without the key being inserted into the ignition. However you must be in range. Key Fobs Key fobs are basically remotes for cars that let you to lock and start the vehicle without ever needing to touch the actual ignition. They are small, rectangular and come with buttons that can be used for various functions. From locking the doors to remotely starting your car they can do everything. They are attached to the key via a small plastic case, which may have buttons to open the trunk and trigger an alarm. Some cars of recent years also come with a combination key that offers the traditional key shank as well as the key fob, the latter usually controlling the ignition. They can also be called a “transponder key.” Many modern car owners use their key fobs as a way to access their vehicle, and most people don't even know that they are doing it. While these devices are great for making driving more convenient, they also come with certain disadvantages that need to be considered. The most obvious problem is that the battery in the key fob could fail. The electronic signals that unlock your car and then start it operate by sending an electronic code to the car's computer, so if the signal is interrupted or is lost the key fob will not be in a position to operate the car. Fortunately, modern key fobs have been designed to deter such threats. They are often programmed with a sequence of random numbers that can be used to generate unique unlocking sequences each time they transmit a signal to the car's system. This prevents old codes from being used again and renders any stolen keys useless to thieves. If the key is lost the key fob will serve as a backup to unlock and start the vehicle. Some manufacturers go one step further by providing apps that can be used to control the car in the event you cannot find your key fob. A professional locksmith can help you replace the lost key fob. They can assist you, and their services are generally cheaper than those of a dealership.
