The methods described below should only be used in emergencies and with the understanding that you are responsible for any consequences.
Using Screwdriver and Drill
- Drill a hole: Using a drill, make a hole in the keyhole of the ignition switch. Be careful not to damage any internal components.
- Insert a screwdriver: Insert a flat-head screwdriver into the hole after drilling the hole.
- Turn the screwdriver: Apply pressure and turn the screwdriver clockwise, simulating turning a key. This should start the engine if done correctly.
By Hotwiring
- Locate the wiring harness: Find the wiring harness under the steering column or behind the ignition switch.
- Identify the wires: Look for the battery, ignition, and starter wires. They are usually red, yellow, and green or blue, respectively.
- Strip the wires: Carefully strip the ends of the battery and ignition wires.
- Connect the wires: Twist the stripped ends of the battery and ignition wires together. The dashboard lights should turn on.
- Touch the starter wire: Briefly touch the stripped end of the starter wire to the connected battery and ignition wires. The engine should start.
Using Red Coil Cable
- Locate the coil: Find the ignition coil in the engine bay.
- Identify the red cable: Look for the cable connected to the coil.
- Disconnect the red cable: Carefully disconnect the red cable from the coil.
- Connect a jumper wire: Attach a jumper wire to the disconnected end of the red cable.
- Touch the battery: Touch the other end of the jumper wire to the car battery’s positive terminal. This should start the engine.
Bypassing the RFID System
- Locate the RFID system: Find the RFID system, usually located around the ignition switch.
- Disconnect the RFID system: Carefully disconnect the RFID system from the car’s electrical system.
- Install a bypass module: Connect a bypass module to the disconnected RFID system, which can be purchased online or at an automotive store. This will allow the car to start without the chip key.
Calling a Professional
Suppose you cannot start your car using the methods above or are uncomfortable attempting them. In that case, it is best to call a professional locksmith or your car’s dealership for assistance.
Always remember that these methods should only be used in emergencies and with the understanding that you are responsible for any consequences. It is always best to have a spare chip key or FOB available to avoid such situations.
How to hotwire a car with a chip key?
- Gather necessary tools: You will need a pair of wire strippers, electrical tape, and a screwdriver.
- Disconnect the battery: Before working with any electrical components, disconnect the car battery’s negative terminal to avoid short circuits or electrical shocks.
- Remove the steering column cover: Use a screwdriver to remove the screws securing the steering column cover, and then carefully remove the cover to expose the ignition switch and wiring.
- Locate the wiring harness: Find the harness connected to the ignition switch. It usually consists of several wires bundled together.
- Identify the necessary wires: Look for the battery, ignition, and starter wires. They are typically color-coded: red for the battery, yellow for the ignition, and green or blue for the starter.
- Strip the wires: Carefully strip the ends of the battery, ignition, and starter wires using wire strippers.
- Connect the battery and ignition wires: Twist the stripped ends and ignition wires together. Secure the connection with electrical tape. The dashboard lights should turn on once the connection is made.
- Bypass the immobilizer: Since the car has a chip key, it likely has an immobilizer system that prevents unauthorized access. To bypass this, locate the immobilizer’s wire (usually a thin white or brown wire) in the wiring harness, and strip its end. Connect this wire to the battery and ignition wires’ connection to disable the immobilizer.
- Start the car: Briefly touch the stripped end of the starter wire to the connected battery and ignition wires. The engine should start. Once the engine is running, remove the starter wire from the connection.
- Reconnect the battery: After successfully starting the car, turn off the engine and reconnect the car battery’s negative terminal.
- Reassemble the steering column: Replace the steering column cover and secure it with the screws.
