How to Remove an Ignition Lock Cylinder How to Remove an Ignition Lock Cylinder
Most vehicles are fitted with a removable ignition lock cylinder or "Interchangeable Cores." These have the advantage of being removed easily, if new keys are required. The procedure may vary between various manufacturers, but nearly all are altered using a special key.
If you are finding it tough to start your car, and have found no problem with the starter or alternator, you may need to replace its ignition lock cylinder. Although, this job is usually done by a professional auto electrician or a mechanic, you can do it yourself if you are confident enough.
You have to get the "core key" for the switch. The core key is like a master key. Rather than unlocking the car doors and locks, it enables the removal of the cylinder, or core, out of the ignition lock casing. The core key is not used to unlock anything, but can unlock a gadget without a key. For instance, a screw driver can be used to open a lock that does not have a core. Troubleshooting and replacing an ignition switch is work that you can do, if you follow the steps below.
Step 1-Disconnect the Battery
Remove the negative cable terminal connection from the battery. Unscrew the screws, to take out the upper and lower covers from the steering wheel column.
Step 2- Remove Steering Wheel
Lift the steering wheel up, by pulling at the center cover. Disconnect the wires connected to the horn, and remove the steering wheel retaining nut and washer. Pull out the steering wheel, to remove it from its shaft.
Step 3- Strip off Wipers and Indicator Switches
Take off the windscreen wiper and indicator switches, by pulling them away.
Step 4- Remove Sleeve from Steering Column
Remove the spacer sleeve from the steering column, by sliding it up after you have removed the wiper and indicator switches.
Step 5- Remove the Ignition Switch
Unscrew the mounting screws for the ignition switch. Pull the ignition switch out. Disconnect wires from the connector at the rear side of the ignition switch. Loosen the tabs to pull it out.
Step 6: Remove the Core
Insert the core key into the core of ignition switch, like any other key. Press down the retaining pin, using a small screwdriver. Turn the key about 10 degrees, to reach the off position. This will release the cylinder from the lock casing. When the key is free, it should be in the locked position.
Withdraw the key slowly from the lock. The cylinder will also pull out of the housing, as you withdraw the key. Please note that if you turn the key back before withdrawing, only the key will come out.
These steps will vary, or you may have to perform some additional steps, depending upon the make and model of the vehicle. Refer to manufacturer’s manual for more details. Each type of car may have a different method for removing an ignition lock cylinder.
