Modern cars require keys that have special chips that can communicate with vehicle systems. These chips must be programmed to work with your specific car which makes it impossible to use any key fob that is compatible with your car, even if it is a duplicate. This makes it more difficult to steal your car but also means you can't just replace your broken key with a new fob and expect it to work. Most people will need to get a locksmith's help to program the key to their vehicle, but it is possible in some cases to do this yourself. To do this, you'll require two car keys that are working. Once you have them you can sit in the driver's seat and access the ignition in your car. Put the new key into the ignition and turn to start your car. This will link the new key to your system, making it a functional replacement for the lost one. This procedure can differ depending on the manufacturer. Consult the instructions that came along with your key, or search online for your specific model/year/make in order to discover the specific steps. If you're looking to save money on your key programming costs, consider purchasing a new keyshell instead of a new key head. The shell is essentially the plastic part that houses the key blade, and you can often buy them for less at auto parts or hardware stores. You'll still need to transfer the internals (the circuit board and chip) from the previous keyhead to the new shell. A professional can save you time by taking care of this for you, but keep in mind that it will cost more than just an ordinary spare key. The professional will need to be equipped with a sophisticated programmer to connect to your car's computer and the device could cost thousands of dollars. On the internet, you may be able to purchase a less expensive version. However, this won't work with your car. The process of reprogramming the key can be difficult and certain cars are more difficult to program than others. Some models have a simple process that can be done on-board or using an OBD2 reader, whereas other models need to be programmed using a specific tool called an EEPROM reader. Some of these tools are only available through dealers and cost a lot. It is best to leave this to experts. How long will it be before a key is programmed? It depends on what type of car you own and whether it has any special anti-theft features. For instance, many vehicles have a system that prevents the key from starting the vehicle if it's not programmed to work with the particular vehicle. This is to stop theft and will require a professional car locksmith for each model. The key needs to communicate with the onboard computer to unlock the doors and begin the engine. A professional auto locksmith will be able to solve this problem quickly. Certain car brands are difficult to program even for a seasoned professional. For these models, the process could take a long time or even days. This is because the process will require EEPROM programming techniques that the majority of locksmiths are not able to. Cars may also come with various other features that require specific programming to work properly. This could include a remote starter, an automatic transmission or power windows. A professional auto locksmith will assist you if your keys have gone missing or are damaged. Before determining which tools are required, professionals will require the manufacturer and model number of the vehicle. They will also require an uncut key that is compatible with their vehicle. Once they have these two items they can program the transponder chip or key fob, and also clone the key, if required. Once all work is completed and the key is tested, they can test the key to make sure it's functional. If the key isn't programmed properly, the security light on the dashboard will stay in place until it is. This is to alert the owner that the key isn't operating properly and must be reprogrammed by a professional. It is essential to have a spare key in case you lose or damage the one you have. It can be costly and difficult to program a damaged key. A professional auto locksmith can complete the task faster and at a lower price.
