Replacing a Problematic Car Ignition Cylinder

Your car’s ignition holds a dual purpose. Firstly it allows you to start the engine. Secondly it forms a protective barrier so should a car thief force entry into your vehicle, they will not be able to simply drive it away.In recent years technology has given birth to a number of clever ignition systems including wireless keys that work on a rolling code protocols. However there are still a large number of vehicles that still rely on the classic key system, which uses basic mechanics and is therefore prone to fatigue and failure.

One of the first and only signs that your ignition barrel is undergoing problems is a sticky key mechanism. If the key is failing to turn properly and you are having trouble getting any response from the engine, then the chances are you should replace this part. It is a fairly simple procedure that can be completed with even the most basic of mechanical knowledge as it only requires minor adjustments under the bonnet.

You will need: adjustable spanner and a paper clip

Remove Power from the Ignition

Open your car bonnet and locate the battery. Using your adjustable spanner remove the cable from the negative terminal, which will usually be located on the right and indicated by a “-“ sign. When you have disconnected the cable put it to one side away from the battery.

Insert Key and Disconnect Cylinder

Put the key into the ignition and slowly turn it round into the accessory position. When this is in place, straighten out a paper clip and insert one end into the hole on the ignition cylinder at the base of the key slot. Now, whilst holding the paper clip in place, turn the key back to the off position. This should now allow you to pull the lock cylinder out of the ignition clip.

Replace Cylinder

Put the key into the new ignition cylinder and insert the assembly into the place left by the old cylinder. When you are satisfied this is in place turn the key to the accessory position and then to the off position to attach it to the ignition system. As a final step you’ll want to pop open the hood and connect up the battery.

The proof that the ignition cylinder is in the correct place is simple. Start your car’s engine in the normal fashion and if there is no sticking or friction with the key then you can be sure you’ve successfully completed the installation.
