I had some issues with my ignition key failing to go into the lock barrel. I removed the barrel and gave it a good clean and lubricated it with graphite. I replaced it and reconnected the battery. Now the car will not start, all electrics are good. There is no click of the starter solenoid. All fuses are OK. The key moves to the start position but nothing happens. Prior to disconnecting the battery and removing the barrel there have never been any issues.

Sounds as though the ignition switch isn’t turning the electrical switch. Have got a spare key to try in case it’s lost connection to security system?

Tony.

The electrical part of the switch is known to fail, however since you have had the barrel out you need to check its engaged correctly with the switch. Take the lower part of the steering wheel shroud off and you will see the switch at the end of the barrel housing. The switch is held in my a small screw, loosen it and the switch will pull out. Check it operates by turning it with a screwdriver and check the end of the barrel that slots into the switch. Refit it ensuring its seated correctly and test it using the key. If it still fails then get a used one from Quarry Motors, I keep a spare in the garage as I thought mine had failed but it turned out the starter motor had died.

Thanks, I had come to the conclusion that there had to be some issue around the switch. I have two keys and both are the same.
