While most newer cars have gone to great lengths to hide the car’s wiring or otherwise secure the steering column with safety measures to avoid breaking the lock, older cars from the middle 90s and earlier are good candidates for unlocking. Breaking the car lock is necessary when you lose your keys while you need to use the car. Always use extreme caution when working with cords and should see the Owner’s Manual for specific instructions on the color coding and type of cord to go with your vehicle. If you want to learn how to unlock the steering column and learn more methods, see Step 1 to learn more.
Steps
Break the steering column lock

Sit in the car. Do not break into the vehicle if you are not the owner of the vehicle and do not have identification. You need to know that the vehicle will alarm when it is broken into if it is equipped with this device.
- This method and the fact that most methods of breaking the car lock will only work on older cars from the mid 90s onwards. Newer vehicles are equipped with a locking mechanism in place that prevents you from breaking the lock unless you are extremely familiar with each vehicle’s characteristics. If you try this method on a 2002 Honda Civic, you will make the car sound the alarm and lock the starter, which means no one can drive anymore.
- If you’ve seen the manual, check to make sure the steering column and gearshift can be disabled. This method can lead to damage to the gearshift mechanism and steering column.

Remove the plastic cover on the steering column. They are usually held in place by sealing clips or #2 Phillips screws. Remove them and pull the shield out.
- Similarly, on some older vehicles, you can break the locking pins on the ignition by tapping a flat-head screwdriver into the keyhole and twisting it out. This is very difficult – if not impossible – to do with your bare hands, but if you think this model is old and can be done, you can give it a try.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/54/Hotwire-a-Car-Step-3-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-3-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/54/Hotwire-a-Car-Step-3-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-3-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Find the seat belt assembly. Once you have removed the frames from the steering column, you should see a spool of wires. Don’t get too confused, learn to recognize the correct bundle of wires. There will be 3 types of typical wire bundles:
- The wires to the pole-mounted controls are on one side, like lights, field controls, and more
- The wires lead to the pole-mounted controls on the other side, like the wipers or seat heating
- The wires to the battery, igniter and starter go straight to the steering column
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/cf/Hotwire-a-Car-Step-4-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-4-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/cf/Hotwire-a-Car-Step-4-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-4-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Pull out the battery, ignition and starter cord assembly. One of these wires is the main power supply for the ignition switch, one is the ignition wire and the other is the starter wire. Colors vary depending on the manufacturer. Check out the user manual and search the internet to be sure you’re aware of all the possibilities.
- Sometimes the ignition wire is brown, the starter wire is yellow, but the battery wire is usually red. It should be noted that the only way to be sure is to read the manual. You simply are not MacGyver, mishandling the wire will immediately electrocute you.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f3/Hotwire-a-Car-Step-5-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-5-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f3/Hotwire-a-Car-Step-5-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-5-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Strip about 2.5cm of insulation from the battery wires and twist them together. Wrap them with electrical tape if available, and don’t let them touch metal parts of the vehicle. Connecting these wires together powers the ignition, so the engine can run when the starter is on.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/95/Hotwire-a-Car-Step-6-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-6-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/95/Hotwire-a-Car-Step-6-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-6-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Connect the on/off ignition wire to the battery wire. You should observe that the dashboard lights and other electrical appliances are working at this time. If all you want to do is listen to the radio, you’re done. If you want to drive, you’ll need to ignite the starter cord, and that’s pretty dangerous. [1] X Research Source

Be very careful, strip the starter cord about 1/3cm. This cord is live so you need to be extremely careful and hold on to the stripped wire. Touch the end of the wire to the wire connected to the battery. Don’t try to twist, you just need to spark the battery wire to start the car.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/7e/Hotwire-a-Car-Step-8-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-8-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/7e/Hotwire-a-Car-Step-8-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-8-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Accelerate engine rotation. If you’ve already started the car, speeding up the engine revs a few times will keep your car from stalling and you won’t have to repeat the process.
- Once the engine has started, you can unplug the starter cord and continue. When you want to turn off the engine, simply remove the battery wire from the ignition wire and the car will stop. [2] X Research Source

Unlock the steering wheel. You’ve got the car started and you’re ready to go for a walk in the sunset, right? Wrong. While the car is moving, the steering column may already be locked at that point, which means you’ll have to break the lock to get it to drive, unless you want to drive straight to a rocky slope or something like that.
- On some models, all you need is to hit the metal keyhole to expose the spring and then break the lock. If you’ve used a screwdriver before on a car you had from the mid 70’s to the mid 80’s, the lock is probably done.
- Some models respond quite well to a sufficient amount of crankcase grease. Turn the steering wheel sharply to the sides as if you were naturally twisting it. You can also use a hammer to fix the steering wheel and use it as a lever. You have to hear a cracking sound and then the steering wheel turns and you can drive normally.
Drill the Locking Pins
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a7/Hotwire-a-Car-Step-10-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-10-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a7/Hotwire-a-Car-Step-10-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-10-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Locate the drill on the keyhole about 2/3 deep of the keyhole. Your goal with this approach is to break the locking pins and allow you to start the car using the screwdriver, not the key. This is a common practice when the car key is lost.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/91/Hotwire-a-Car-Step-11-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-11-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/91/Hotwire-a-Car-Step-11-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-11-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Drill in to a depth equal to the length of the key. Each padlock has two sections followed by a spring, so drill at least twice, bringing the drill out after each drill so that the locking pieces inside are in place.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a2/Hotwire-a-Car-Step-12-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-12-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a2/Hotwire-a-Car-Step-12-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-12-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Insert the screwdriver like you would a lock. You don’t need to go deep because the locking pins are broken. Do the same as you would a key, turning about a quarter clockwise to start the engine. [3] X Research Sources
- Warning: this will damage the lock and anyone with a screwdriver or strong nails can steal your car.
Power Transmission to Control Panel
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/97/Hotwire-a-Car-Step-13-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-13-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/97/Hotwire-a-Car-Step-13-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-13-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Open the car’s front cover and locate the red coil. Both the wiring harness and the filter wire are located at the back of most V8s. Four-cylinder engines are usually located on the right side, near the center of the engine. The six-cylinder engine is located in the opposite position: on the left side, near the center of the engine.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/78/Hotwire-a-Car-Step-14-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-14-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/78/Hotwire-a-Car-Step-14-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-14-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Take out the starter cord. Connect the priming wire from the positive terminal of the battery to the positive terminal of the coil, or connect the red wire to the coil. It will help transmit power to the control panel, which is essential if you want to start the engine.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/48/Hotwire-a-Car-Step-15-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-15-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/48/Hotwire-a-Car-Step-15-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-15-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Identify the starter coil. In Ford vehicles, it is located on the right side of the shield, next to the battery. In GM vehicles, it is located on the starter below the steering wheel.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/20/Hotwire-a-Car-Step-16-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-16-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/20/Hotwire-a-Car-Step-16-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-16-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Unlock the steering wheel. Place one edge of the flat-head screwdriver on the center top of the steering wheel, pushing the part between the steering wheel and the steering column. You want to push the locking pin out of the rudder. Don’t worry, you can be aggressive at this step.
- The latch won’t open or ring an alarm so you should look for the coil underneath.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/14/Hotwire-a-Car-Step-17-Version-5.jpg/v4-728px-Hotwire-a-Car- Step-17-Version-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/14/Hotwire-a-Car-Step-17-Version-5.jpg/ v4-728px-Hotwire-a-Car-Step-17-Version-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Connect the coil to the positive terminal of the battery. You should see a small wire at the top of the coil and the battery anode wire below. Remove the ignition wire from the coil and, using an insulated screwdriver, connect the positive terminal of the coil to the connection point to the ignition wire.
- This process will supply 12V current to the battery. It will activate the coil and the starter will start the car.
Advice
- You risk damaging the vehicle if you break the lock.
- Vehicles with a computer chip in the ignition will not be able to perform the lock, the chip will activate the Electronic Control Unit to work, without it the car will not be able to run.
- Never let the ignition wires get twisted together once you’ve started the car. It could cause the vehicle’s ignition system to catch fire or at least drain the battery.
- Most cars will sound an alarm when you break the wrong lock.
- Apply this knowledge responsibly.
Warning
- Wear insulating gloves.
- If the ignition wire comes loose while you’re driving, the engine will die instantly, and your car will be deemed to be out of fuel, unable to drive, or unable to brake.
- Do not use this method for illegal purposes such as car theft.
