In this blog, I will explain to you step-by-step How to do Key fob Programming or in simple words how you can Reprogram your Key Fobs, so you don’t have to take it to an auto-dealer and spend your money.
A Key fob is a small security hardware device with built-in authentication used to control and secure access to mobile or computer, network, and data. The key fob displays a randomly generated access code, which changes periodically usually every 30 to 60 seconds. Users will first authenticate themselves on the key fob with a personal identification number, followed by the current code displayed on the device.
In this article, we are talking about car key fobs.
If you are like me, it is safer to have a backup key for emergencies. Don’t limit yourself to having only one key fob, you never know when that one key will need replacing!
The battery might die in the fob and you decide to replace it yourself.
I think no one on the earth likes to give their money to someone if they know how to do that stuff. So this might be a good reason to learn How to program your key fob.
Maybe you purchase a used vehicle that only comes with one key instead of two. Or maybe it’s a family car that multiple people drive, meaning they each need their key.
Ok, let’s jump right into it:
Note: Different cars have different ways to reprogram their key fobs. The process mentioned below is the simplest way to reprogram any key, but sometimes you need to find information for your exact car model. You can find more specific information about your car’s remote from the manual.
Replace the battery of key fobs if you haven’t done so for a while. A bad battery can give you a headache while you are trying to program/reprogram it. The batteries are often cheap and also easy to replace.
You can free to check the car’s manual if you do not know how to replace them.
Get in the driver’s seat with your car keys and the remote and close all the doors. As it may disturb the process of programming your key fob if you leave one open.
Now, Insert the key into the ignition and turn to the ‘On’ position (so the electrical systems are powered).
Make sure that the ignition is not in the radio mode, and do not start the engine.
With the key in the ‘On’ position, press the fob’s lock button and turn the key back to the ‘Off’ position. Repeat this process at least three times, end cycle with the key in the ‘On’ position.
This sends an indicator to your electronic control units that it’s your key in the ignition sending out the signal, and it does save the data afterward.
Once you have repeated the above process, you will hear the lock sound. This indicates that you have entered the programming mode. Once this is done, press the lock button again within five seconds, and the programming will succeed.
Once you are done, turn the ignition back to the ‘Off’ position to terminate the programming procedure.
Take your key fobs with you and leave the vehicle and close all doors. Test to both unlocks with your key fobs that got programmed to verify the function.
If you still have trouble with Programming your Key fob I highly recommend you to go to any auto-dealer and ask for this they usually do it for you for 60$.
