How do I get a key programmed?

Reprogramming a car key involves inserting a blank chip into the key and programming it to be compatible with your vehicle's current settings.

What do I need to get a key programmed?

Modern vehicles require keys that have special chips that communicate with the car's systems. The chips are programmed to work only with the vehicle you own and make it impossible to use any other key fob, even if it has duplicate. This makes car theft more difficult but also means that you cannot replace your broken key with a new fob and expect it to work. Most people will need to contact a locksmith to create the key to their vehicle however it's possible in some instances to do it yourself.

To accomplish this, you'll require two car keys that are working. Once you have them, sit in the drivers' seat and open the ignition. Then, put the new key in the ignition and turn it to start your vehicle. This will connect the new key with your system, making it a functional replacement for the key you lost. This procedure can differ according to the manufacturer, so you should review the instructions that came with your key or look up your specific year, make and model online to find the exact steps.

If you're looking to save money on your key programming expenses, think about buying a new key shell instead of a new head. The shell is the plastic piece with the key blade, so 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 one.

It can be done by a professional, however it will cost you more than a spare key that you can buy. The professional will have to have an advanced programmer to connect to the computer in your car and this equipment can cost thousands of dollars. Online, you may be able to buy a lower version. However, this is not compatible with your vehicle.

Reprogramming a key can be complicated and some vehicles are more difficult to program than others.

Some of these tools are only available from a dealer, and they are expensive, so this is something you should leave to an expert.

How is the time it will take to have a key programmed?

It's all dependent on the kind of car you own and whether it comes with special anti-theft features.

A professional auto locksmith will be able to figure this out quickly.

Even for experienced professionals, some models of cars can be difficult even to program. For these models, the process can take days or even hours. The procedure requires EEPROM programming procedures that locksmiths do not have.

Cars can also have many other features that require a specific program to operate properly. This could be a remote start, automatic transmission or power windows. A professional auto locksmith will help you if your keys have gone missing or are broken.

Before determining the exact tools needed, most professionals will require the make and model number of the vehicle. They will also require a blank key that is compatible with their vehicle. Once they have these two items they can program the transponder chip or key fob and clone a key, if required. After all the work is done the key will be tested to ensure that it works.

If the key isn't properly programmed the security light on the dashboard will stay in place until it is. car key programming is to notify the owner that the key isn't working properly and needs to be reprogrammed by an expert.

It is essential to have a spare key in case you lose or damage the one you have. However, if you've got a broken key or fob that has to be programmed, it can be time-consuming and expensive. A professional auto locksmith is able to complete the task faster and at a lesser cost.
