Check Your Key And Door Cylinder

The first thing you need to do if your engine fails and the Immobilizer is on, preventing access? Make sure you’re using the right key; double-check for lost or forgotten keys in case it isn’t yours. If not, look out preferably with another one of your own, which unlocks both doors and turns on ignition as well, so no mistake can happen again!

And lastly, rule out dead batteries by inspecting them ourselves before getting replacements from somewhere else. This time around, be more careful than usual about where these things come into contact since they only work through RFID transmissions and nothing else!

Also, check if the door is in good shape and that there are no signs of forced entry. If you feel confident that nothing has been tampered with or damaged, then proceed to step two!

Deactivate Immobilizer System

To deactivate this system, you’ll need to look for the key code on your key that will tell you which immobilizer system is installed or ask your dealer to provide that information for you. Once you have that information, you can deactivate this system.

It will be necessary to either have the chip that corresponds with the code sent to a professional automotive locksmith or simply take your vehicle into a locksmith shop so they can copy the code manually.

Test Key

Once you have gotten this key copied, test it by inserting it into the ignition to see if it will start your vehicle. If this key doesn’t work, you’ll need to go back and get another copy made so you can try it out again.

Set Any Other Keys

If your key does start your car, then all that’s needed is for you to have any other keys that you have made for your vehicle so that you can easily drive it.

Record All Codes Used To Start Car

If this key doesn’t work, there’s a good chance that you may find yourself sitting at the side of the road waiting on some help to come along soon, but by having written down all the codes used on the keys that have allowed you to start your car, this will be able to help in an emergency situation.

This information can also be used for the purposes of having the keys copied by a professional locksmith so that they don’t miss any codes when doing so, which would prevent it from working properly once more.
