Default Ignition Key Difficult to get in the lock.

This has been happening off and on just recently, you can't push the key into the barrel, just solid won't go in, then keep trying and it goes in. The next time will be okay, but the problem returns randomly. Any ideas ?

You could try rubbing a soft grade pencil tip up and down the key blade. It worked for me, as the graphite eases insertion.

I used to have it where occasionally I couldn't turn the key unless I moved the steering wheel due to the steering lock being engaged, wonder if it could be similar here. Next time the key won't go in try moving the steering wheel.

The graphite is a good idea But------------It's probably the spring loaded tumblers that are sticking.

You need a liquid lubrication like WD 40 that will run down around the spring plungers and unstick them.--

Wouldn't advise WD40 as it can attract dirt and gum up a lock.

I believe that WD info says the opposite and thin oil might gum up things a bit as WD 40 is supposed to clean them. The WD does seem to evaporate after a while though and leaves hardly a trace of it having been there.

Personally I have, over time, unstuck lots of things that have stayed un-stuck using WD 40.--The main thing to keep it off is anything with pure rubber in as opposed to synthetic stuff. Pure rubber swells up..--

Over here in France I have bought a couple of spray cans that appear to have a very light oil in them coupled with Graphite. The oil seems to almost vanish leaving a semi-dry lubricant in the exact place you want it to be. Might be on sale too in the UK.

Graphite powder and white grease is the correct method.

You need something that acts like Wax-Oil. Flows into where it's needed then semi-sets. Graphite powder and white grease won't flow. They need something like the pressure of a grease gun to get where they are needed.

You won't have much luck with an ignition lock unless you use a grease gun.-----------


You only have to look at a cross section through the ignition lock to see what I mean. Those plungers and springs need liquid lubrication.---



That white grease is great on boats as it's waterproof. Used it for over 20 years of boating off Teignmouth in south west Devon in my sea fishing days. Prop shaft seals, pulleys and cables etc.

Better off with LMH grease in car applications. Wheels ,bearings, bonnet cables etc.

I would take the lock barrel out & give it a good wash & blow out with an airline, that what I did with mine . I found it better just dry and clean. I seem to remember one needed to take off the cowling, prise off the transponder coil , and the barrel will come out with the key in the first position using a straightened paper clip pushed down the small hole at the edge of the barrel which then releases it.
On another 75 I had a new barrel supplied through XPart coded from the vehicle VIN to the existing key, so I didn't end up with a mismatched set of keys.
