Basically what you have is a device that locks onto your steering wheel, so if anyone breaks into your vehicle they cannot steer your vehicle because it limits the movement of your wheel. A couple of the nice features, one is the push button lock so when you set it to where you want it you push the button and you are done. Also at the end you will see there is a flashing LED that will make it look like you have an extra security device on it. Now we will show you how it installs. It is pretty easy. You just put it over the center and spread it apart and when you get it to your desired length, you just push the button. Now you push this little blue button to make it official. To uninstall it, you simply turn your key until the lock pops back out and you are done. There you have it for part # 263DAT, the TI3 high security steering wheel lock.
