Step by Step Guide on How to Break Ignition Lock Cylinder

Step One: Identify Your Car

The first step to breaking the ignition lock cylinder is knowing which kind you have. To do this, try locking and unlocking your car with your keyless remote. If it works, you have a transponder-based system.

Transponders are small radio frequency transmitters placed inside of your keys that communicate with the car. If it doesn’t work, you might have a non-transponder system. If the car is still old enough and hasn’t been re-keyed by a previous owner, or if it’s a rental car, you probably have a non-transponder system.

Step Two: Get Your Drill Ready

Now that you know which system you have, it’s time to get your drill. First, make sure you have a drill bit that matches your transponder key’s blade. If it’s the wrong size, the lock won’t budge, and you’ll just be drilling into the blade.

Make Sure You Have a Drill Bit That Matches Your Transponder Key's Blade

Non-transponder keys may also have a flat blade or a different colored key head. If this is the case, make sure you get the appropriate drill bit for these blades.

Step Three: Drill In

Take your drill and place it on any of the grooves at the top of the lock cylinder. Drill into it until you feel resistance. Then, drill around the grooves, including the center pin, until they are no more. Take note that it takes more time to drill this type of lock, but you get the satisfaction of breaking into your car.

You can also use a screwdriver instead of a drill for this procedure. If you choose to do so, make sure you have either an electric or manual screwdriver. A flathead screwdriver will not work. However, now that you know how to break an ignition lock cylinder, you can save yourself some money and do it yourself.

Step Four: Get Your New Ignition Lock Cylinder

Once you’ve opened up the old ignition lock cylinder, please take note of how it looks. If you have a transponder system, the metal blade should pull out easily. Otherwise, your keys might be stuck inside, so get your magnet ready. Then, compare this to a new ignition lock cylinder and choose the appropriate one.

Insert Your New Ignition Lock Cylinder and Push the Metal Blade Inside

After doing so, insert your new ignition lock cylinder and push the metal blade inside. It should fit in securely without any problems or resistance. This might take a try or two but keep at it until it fits in. Once you’ve done this, take your screwdriver or drill and make four vertical grooves around the circumference of the center pin. This will keep it secure during use.

Step Five: Reassemble Everything

Insert the key into the ignition lock cylinder. Now that you’ve broken into your car, turning it on should be easy. If not, you didn’t put the key in all the way, or your blade is facing the wrong direction. Please take note of which side faces up and make sure it gets inserted correctly every time. In addition to doing this, check if anything is blocking it from turning.

Take everything apart again and look at how the ignition lock cylinder works. Make sure your key fits in there smoothly and easily. If it doesn’t, you might have a faulty ignition lock cylinder that needs to be replaced.

Step Six: Test Your Car

Once you’ve put everything back together again, test whether or not the new ignition lock cylinder works. Try locking and unlocking the car with your keyless remote. If the car responds, it means that you’ve done everything correctly.

Try Locking and Unlocking the Car With Your Keyless Remote

If not, or if you have a flathead screwdriver instead of a drill, this is a sign that your ignition lock cylinder is faulty and needs to be replaced. In either case, it’s time to visit a professional. Otherwise, you can go ahead and use your new ignition lock cylinder to drive the car again.

Step Seven: Enjoy the Power

When you do get the new ignition lock cylinder to work, enjoy your newly acquired power. Don’t let anyone drive your car ever again and lock all of your friends out. Although you probably won’t go on road trips together anymore, this is a small price to pay for knowing how to break into your car.
