Having trouble with a faulty ignition switch and no key? Whether you’ve lost your keys, the key is broken, or the ignition cylinder itself is jammed, removing the ignition switch lock cylinder without the key can seem daunting. This guide provides a step-by-step process for safely removing a non-functional ignition switch lock cylinder when you don’t have the key. This procedure is typically required when the lock cylinder is inoperative and cannot be rotated.
Step-by-Step Guide to Removing a Keyless Ignition Switch
Here’s how to remove your ignition switch when you’re facing a lost key or a jammed cylinder.
-
Disconnect the Battery: Safety first! Before starting any electrical work on your vehicle, disconnect the negative battery cable. This prevents accidental shorts and ensures your safety throughout the removal process. Refer to your vehicle’s service manual for the specific location of the negative battery terminal and proper disconnection procedures.
-
Remove the Steering Wheel: Gaining access to the ignition switch mechanism often requires removing the steering wheel. This provides the necessary clearance to work on the steering column shroud and access the ignition switch components. Consult your vehicle’s repair manual for detailed instructions on steering wheel removal, as procedures can vary across models.
-
Access and Drill the Retaining Pin: Locate the access hole on the lower steering column shroud. Using a small pilot punch, carefully center punch the retaining pin visible through this hole. Once centered, use a 1/8-inch diameter drill bit to drill out the retaining pin. Drilling out this pin is crucial as it secures the ignition switch lock cylinder in place.
-
Separate the Ignition Switch Cap: With the retaining pin drilled, the next step involves removing the ignition switch cap or bezel. Employ channel lock pliers or vise grip pliers to firmly grip and twist the ignition switch cap or bezel. Continue twisting until it separates from the ignition switch lock cylinder. This might require some force, but be careful not to damage surrounding components.
-
Drill the Lock Cylinder: Now, using a 3/8-inch diameter drill bit, carefully drill down the middle of the key slot. Drill to a depth of approximately 44 mm (1.75 inches). This process is designed to break the ignition switch lock cylinder loose from its breakaway base. Drill slowly and steadily to maintain control and avoid damaging the steering column housing.
-
Remove Components and Clean: Once the lock cylinder is broken loose, you can remove the lock cylinder itself along with any drill shavings. Also remove the bearing retainer, steering column lock housing bearing, ignition switch lock cylinder, and steering column lock gear. Thoroughly clean the steering column lock cylinder housing to remove all drill shavings and any other foreign materials. This ensures smooth operation of the new ignition switch.
-
Inspect for Damage: Carefully inspect the steering column lock cylinder housing for any damage that might have occurred during the removal process. If you notice any significant damage, it is essential to replace the steering column lock cylinder housing before proceeding with installation.
Installation
Installation is generally the reverse of removal.
-
Replace Damaged Housing: If the steering column lock cylinder housing was damaged during removal, replace it with a new one.
-
Install Bearing and Retainer: Install the steering column lock housing bearing and bearing retainer as per your vehicle’s service manual.
-
Install Trim and Electrical Parts: Reinstall any trim pieces and reconnect any electrical components that were removed during the process.
-
Install New Ignition Switch Lock Cylinder: Install a new ignition switch lock cylinder. Ensure it is compatible with your vehicle and follow the manufacturer’s instructions for proper installation.
-
Reinstall Steering Wheel: Reinstall the steering wheel, ensuring it is properly aligned and secured.
-
Reconnect Battery: Finally, reconnect the negative battery cable.
-
Check Operation: Test the operation of the new ignition switch lock cylinder to ensure it functions correctly.
