Cost of Car Key Replacement Losing your car keys can be a huge hassle and can be expensive to replace. The cost can vary depending on the type you have. Contacting a locksmith or dealer for an estimate is the best way to find out how much it will cost to replace keys. Here is a list that includes several factors that could affect the price. Transponder Keys Transponder keys, also referred to as chip keys, contain an electronic microchip that is embedded in the keyhead. When the chip is placed in the ignition lock cylinder and it sends a coded message to the immobilizer of the car. This code is in line with an ID number attached to the vehicle. This makes it extremely difficult to steal a vehicle since it isn't able to be started without the proper code. The motivation behind the creation of this type of key was to make it harder for thieves to wire a vehicle. Before the invention of this technology it was quite easy for thieves to start vehicles by connecting two wires, a process called "hot wiring." The transponder keys are secure because they require a unique code to be activated. They are extremely difficult to duplicate with standard tools, and need to be duplicated only by an auto locksmith. In the end, the transponder key is more expensive than conventional bladed keys. However, this cost is often worth it in the long run, especially when considering the security benefits that come with this kind of key. Consider the importance of security for you before deciding to purchase transponders. Consider your budget and lifestyle before deciding if the expense is worth it. Car dealerships often charge a premium for car key replacement services. This is due to the fact that they are the only dealers of certain car models and have large expenses. There are many professional locksmiths for cars that provide the same service at lower cost. If you're unsure if your car has a transponder chip, you can consult the local dealer or auto locksmith. They'll be able to determine if your vehicle is chip-equipped and can also help you determine the cost of getting a new one. If you decide to go with the less expensive non-transponder keys or the more expensive transponder key it's essential to find a reliable auto locksmith that has worked with your model of car. Laser-Cut Keys Certain newer cars use keys with more sophisticated designs known as a sidewinder or laser cut key. These keys are made by a locksmith or dealer and include an embedded computer chip in the keys. These keys are more expensive, but they provide more security. This is the reason why they're the best choice for those who are looking to protect their car from theft. Laser-cut keys are different from regular two-sided keys since they only have a cut in the middle. These cuts are more precise and harder to duplicate than the standard notches on regular blades. They are also difficult to discern and are a great deterrent for would-be thieves. To create a laser-cut key, dealers or locksmiths use an exclusive milling machine. These machines employ a tool that looks like a drill to slowly remove the key's metal. They can take out the exact amount of metal needed to make the key in question and provide an extremely high level of accuracy which makes it difficult for thieves to make their own copy. Another reason why keys that are laser-cut are more secure than conventional keys is because they can't be used to unlock similar vehicles like they would use regular keys. When a standard car key is used, it sends a signal the vehicle which allows it to recognize it. This is why the engine will refuse to start if it detects an unrecognized key. Laser-cut keys, however, have a built in transponder that is registered to a particular vehicle. This means that even if a burglar can cut and program a laser-cut keys, the engine will still not start. A technician will need the Vehicle Identification Number (VIN), of the vehicle, to locate the CNC machine's specifications to cut a laser-cutkey. The process can take anywhere from 15 minutes up to a few days, depending on the model and brand of the vehicle. Once the correct specifications are entered, the laser-cut key is ready to be programmed by the locksmith or dealer. Dealerships The process of replacing your car keys at a dealership is the most expensive option, but it is often necessary. It is usually covered by your insurance or warranty. Check with your auto insurer to ensure that the replacement of keys is covered in the policy. It's also a good idea to get any stolen, lost or damaged keys deprogrammed by the dealership, since this will ensure that no one will be able to use them in the future. If you have a standard fob replacing it at a dealership may be the least costly alternative. If your key fob has a built-in chip and cannot be duplicated it is likely to cost more to have it replaced at the dealership or by locksmiths. The cost of a key fob can vary widely depending on your car's model and make. It is recommended to talk to local locksmiths, mechanics, or dealerships to get an accurate estimate. Another way to cut costs is by bringing your spare key with you to the dealer and having it copied there. This can be cheaper than having it cloned by a locksmith, however you'll want to make sure your spare key is compatible with your vehicle. If you're replacing your car key at the dealership or through locksmiths, it's essential to take the time to note down your vehicle identification number (VIN). This will ensure that your replacement key fits correctly and can be connected to your vehicle. You will be able to locate your VIN on the dashboard of your vehicle on the windshield at the corner of the windshield and on the side of the engine block or in the owner's manual. In the past, losing a car key was no big deal. Modern technology has made it more difficult to replace keys, and this could be costly. Always keep a spare car key at and ready in the event that your keys are stolen or lost.
