If your car / truck key is lost or the key fob is broken, getting a replacement can be a chore and it can cost a pretty penny depending on the type of vehicle you drive. A car key programmer enables you to reprogram keys, program new keys, and set up the IMMO system so that you are ready to use again. This saves you time and money. Some automotive scan tools have important programming functions built in. These models are often designed for experienced DIY enthusiasts or professionals. A standalone key programmer is a lower cost option for drivers or locksmiths who do not require scan tools functionality. I will make sure that after reading these instructions you will find a suitable one for your car key. Choose the type you want and go with me!
The Xhorse VVDI key programmer is a professional tool that can perform multiple functions. It is equipped with Bluetooth and WIFI connectivity for communication to the Xhorse key cutting machine, mini OBD tool, and other subsidiary products needed for other purposes.

Let’s look at the similarities and differences of the tools in the detailed comparison below:
Transponder key programming
Transponders were introduced in the late 1990s to improve car security. This involved embedding chips in the car keys, which emit signals to communicate with your car IMMO system. The car will never start if an incorrect signal sequence is received, even if you can flick the mechanical switch on the ignition.
Replacing car keys with transponders has since become a problem, requiring advanced car key programmers. Autek Ikey820, VVDI, and CK100 are all having this capability.
