lubricating ignition key barrel

My ignition key has started to not always spring back after turning the key to the start position, or at least spring back slowly. I believe my procrastination to fix it cost me a starter yesterday when my wife and daughter went for a drive - I think it stayed in the start position and burned up the starter.

Any do's or don't here? I was thinking of trying some powered graphite in the key hole, but don't want to make it worse.

tia,
charles

I always use a product called Lock Ease. It's like a fast drying liquid graphite. Works mint for me. I personally would avoid any kind of oils and stuff. That attracts dirt in my opinion.

Yeah that's what I was thinking. Ok, hopefully graphite will solve it. I guess it would be hard to make it worse. lol.

I heard that you shouldn't use graphite on Land Rover locks... It mixes with their lubricant and acts like a glue or something like that... I think they suggested a Kevlar lube or something like that.... Microlube.... I can't remember.. I'm sure you can do a search for it...

I use a little 3-in-one in the slots of the key. Probably not ideal because it might breakdown the OE grease but I try to keep up in it 2-3x year.

What? Could a starter really stay on with the cylinder not fully popped? I have to jiggle the cylinder a bit after I pull my key out. Otherwise I'll get the warning bell that my truck still thinks the key was left in the cylinder. I never paid it any mind because if someone opened the door, it'll ding like as if they set off an alarm. Nice effect! ;-) But when I park it securely or for a longer period, I always give it a jiggle so that it pops fully just in case.

Listen, I wasn't there, so let me explain what I know and see if you'd come to the same conclusion.

Wife and daughter (with learners permit) went off for a drive. Wife started it and backed out of the garage, then daughter drove. They trolled the streets of the hood for maybe 10 mins? Came to a stop sign and it died. Said smoke was coming out form under the hood. Awful burning smell. Truck would not start. Ignition switch definitely sticks and does not spring back.

When I got there, the smoke was gone, smell still there and seemed to come from the starter area but can't be sure. I check battery voltage, could hear a relay click but not a peep from the starter. I had a spare starter in the troy box, but tools were at home and the engine was hot so I just said F it, and took a tow of shame home.

Yesterday after work I checked for voltage at the starter, and the exciter wire when the key was turned, so swapped in my replacement starter and it fired right up. Went for a test drive for 10-15 minutes, long enough to come to full temps, and long enough that if something was going to blow, it would have.

So that's why I can only assume the starter was engaged an just burned up. Have not tried to bench test it or anything yet - need to go diagnose a BMW misfire right now

Been using WD40 for 25 years on mine, twice/yr. so while it may be a problem, it is slow to show. And have used on Defenders, Classics, Discos, even Series- remember WD is water displacing.

Lock

Charles-same thing happened to me a year ago. Smoked my starter. I replaced it and went to Cherrydale Hardware in Arlington, described my problem and the guys inside took a lubricant called Tri-flow or something rather, gave it a squirt or two (free of charge) and it always springs back. I'd look into this stuff.

Thanks all

Damn, there is a lot of conflicting info out there on this one. I still haven't done anything yet, but thinking maybe "flush" it with brake cleaner and then use a teflon based lubricant like TriFlow.

Oh, definitely! I think you've got it pegged. My cylinder issue is not remotely identical as it is purely related to the key, whilst yours was rotational recoil. Sorry you had the tow of shame despite having the solution on board. I bet it was sitting right there in the Troy next to a spare fuel filter, sender, and stepper! ;-) Best of luck with the bummer bimmer and all the best.

Just for the record, I found I had a liquid graphite product called "Lock Ease" on the shelf (no recollection of buying this ever), so gave it a few squirts. The lock feels great and springs back fine now. Time will tell if it's a good long term fix

Only down side to graphite is your key gets that pencil lead on it.... Eventually it does work it's way into the lock

Yeah my daughter found that out before I had a chance to warn her to wipe off the key before putting it in her pocket. LOL

Before you're trapped....

replace the switch.....it's such a simple job and wish I'd have done it before I was in BF Kansas.

Having said that, I "squirted" dry graphite into every hole...ha ha...that's what she said...and am amazed at the difference in turning effort and smoothness.

I say, try graphite..
