If you have a reputable and experienced auto locksmith with the appropriate equipment, they can complete the process quickly for you.

These pieces of software are not compatible with all models or brands and may be difficult to use. It is better to let a professional software the key to your success because they have the proper tools and will know exactly how to use it.
You'll require an assortment of keys that match your vehicle's model and make to do this. You can buy them on the internet at a bargain cost, but make sure they're blank. You can also go to a locksmith, but these are more likely to charge you more as they need to purchase their own software and advanced car key programming tools to program your car keys for you.
These sophisticated key programming devices for cars are expensive and available only to professionals with the right license. In addition, these cars typically have a "token" system that allows only one program attempt to be made every day or hour. This means that if you try to program a key over and again, it's possible that the code on the car will corrupt.
It is recommended to let an experienced auto-locksmith reset your keys. They will have an understanding of the software and security systems involved, which will greatly lower the chance of corruptions or errors occurring.

What are the prerequisites to program a key?
Modern vehicles require keys with special chips that can communicate with car's systems. These chips must be programmed to work with your specific vehicle and make it impossible to just use any key fob in your car even if it's a duplicate. This makes car theft more difficult however, it also means that you cannot replace your broken key with a brand new fob and expect it to work. This is the reason why most people will need to contact an auto locksmith to program the new key for their vehicle, though it is possible to do it yourself in certain situations.
To accomplish this, you'll require two car keys that are working. Once you have them, you can sit in the driver's seat and open the ignition. Insert your new key in the ignition, then turn it on to turn on your car. This will link the new key to your system and make it a functioning replacement for the lost one. This process can vary slightly depending on the manufacturer. Consult the instructions that came with your key, or go online for your specific model/year/make in order to discover the specific steps.
Consider purchasing a keyshell rather than the head of a key if you are looking to cut down on key programming costs. You can purchase the shell, which is the piece of plastic which holds the key blade, at less cost in hardware or auto stores. You'll still need to transfer the internals (the circuit board and chip) from the old keyhead to the new shell.
A professional can save you time by taking care of this for you, but be aware that it is more expensive than a regular spare key. The professional will have to have an advanced programmer to connect to your car's computer and the device could cost thousands of dollars. On the internet, you may be able to buy a lower version. However, this will not work with your vehicle.
Reprogramming the key can be difficult and certain cars are more difficult to program than others. Some models have a simple procedure that can be completed via the onboard computer or an OBD2 reader, while others require being programmed with a specialized tool called an EEPROM reader.

How long before the key is programmed?

The key must be able to communicate with the computer onboard to unlock the doors and begin the engine. A professional auto locksmith will solve this problem quickly and efficiently.
Some car brands can be difficult to program even for a skilled professional. The process can take hours or days for these models. This is because the process will require EEPROM programming procedures that most locksmiths are not able to.
Other features of cars could also require programming in order to function correctly. This could be remote starts, an automated transmission, or power windows. In these cases a professional auto locksmith will be able to assist if you have lost or broken keys.
Before determining the precise tools required, the majority of professionals will need the make and model number of the vehicle. Additionally, they will need to have a key blank compatible with the vehicle. Once they have these two things they can program the key fob or transponder chip as well as duplicate the key if required. After all work is completed, they will test the key to make sure it's functioning.
If the key isn't properly programmed, the security light on the dashboard will stay illuminated until it is. This is to notify the owner that the key isn't working properly and needs to be reprogrammed by an expert.
