The Key Won’t Turn
Because of the position of the ignition hole on the 450, 451 and Roadster, it’s very common for them to get full of shit like dust, cake, sugar, fur, crumbs, bogies, chocolate, finger nails etc. The ignition barrel isn’t open underneath so anything that falls in, stays in. Eventually it can stop the key going in all the way or it’ll interfere with the mechanism.
If the key isn’t all the way in or the pins/discs don’t line up, the key won’t turn. If the key don’t turn, you ain’t goin’ anywhere.
Clean Out Your Slot
The 450 and Roadster use standard pin tumbler cylinders.
The 451 and 453 uses centre disc cylinders. The keys are often called Laser keys or Sidewinder keys.
The 450 and Roadster suffer more because of the cylinder design.
Step 1 – Vacuum
Get your vacuum, fit the nozzle and start vacuuming the ignition hole. This will help pull out loose stuff.
Step 2 – Pressure
If you have a compressor and air duster, go for it. If not, you can buy cans of air duster. The cans are very good as they tend to have a straw that can be put into the hole. Once you have done this, try vacuuming it again to remove anything you have dislodged.
Step 3 – Lubrication
Don’t be tempted to use WD40 or any other wet lubricant. You need a dry lubricant such as graphite powder.
Puff some into the hole.
This shit gets everwhere.
Put the key in and out of the ignition a bunch of times to help distribute the graphite lube.
Step 4 – Vibration
Place the key into the ignition…
…and grab something that vibrates. I have a DA sander but you can borrow your wife’s vibrating fish bonker.
Hopefully at some point between step 1 and 4, your key will turn as it should do.
Last Ditch Attempt
Remove the SE Drive, click here. Turn it upside down and smash the side to try and dislodge anything stuck in it.
