If your vehicle won’t turn on and you see a little car and lock light on your dashboard, your anti-theft system is probably preventing the car from turning on. As confounding as this may be, the solutions here are probably very easy to carry out, and you don’t need any fancy tools or complex diagnostic gear. In this article, we’ll show you how to fix the anti-theft system so that you can back on the road.
Things You Should Know
- Try using your spare key. If the vehicle turns on, the transponder in the other key is dead. Take it to a dealership to get it fixed.
- Unlock your door and disconnect your battery to reset the vehicle’s computer and turn the anti-theft system off.
- Manually reset the transponder connection by turning the key to the “on” position for 10 minutes, then turn it "off" for 30 seconds. Repeat the process 3 times.

Tips
- Some vehicles have a dedicated fuse for the anti-theft system. If this fuse is blown, your anti-theft system may assume someone is tampering with the vehicle and it won’t start. Purchase a replacement fuse and find the fuse location on your electrical panel by reading your manual. Remove the old fuse and put the new fuse in place . [7] X Research sourceThanks
- Bad wiring can also cause an anti-theft system to turn on when it shouldn’t, although this seems to be a relatively rare cause on most vehicles.Thanks
