[diesel_mercedes] Routine Lock Lubrication

 


Go to Chrysler / Jeep Dealer and ask the Parts Dept. guy for " Heat Riser Solvent " ~ it comes in a shaving cream can (remember those ?) with a plastic snorkel in the nozzle , what it is is graphite in a light carrying fluid that you shoot into the key holes and them work the key back and forth a few times , have a clean rag handy as you should spray it in the keyhole until it burps back out .

This same product will work wonders on every key lock you have , NOW is the time of year to do every lock on the property so they'll work easily and smoothly until spring .

DO NOT get suckered into using WD40 or other worthless crap in key locks ! it's a solvent that washed the dirt and lubricant out allowing temporary ease of operation as the lock's delicate innards rapidly grind them selves to death .

I have posted the MoPar P/N before .

I went to lock my car (80-240) the other day, the locks have always worked good, but this time the key would hardly turn, I did lock it, very carefully, it felt like the key might break if I turned it normal like. Is my car getting old or something?  What to do? Max

[diesel_mercedes] Sticky Key Lock

 



Now you should puff some graphite into it .

As Brian mentioned , once in a while the key lock cylinder will be *so* bad / dirty / gummed up you'll have to take it carefully apart and clean it , re lubricate with graphite grease then re assemble .

I always try to do this with a few extra junk yard locks at hand and I find I can swap out the old worn brass ' dogs ' to better match the key you have .

When my ignition lock played up for the last time I took desperate
measures and flooded the cylinder with WD-40. Believe me, I know this
is not what you should do. The cylinder immediately worked and has
worked for months. I figured, what do I have to lose.
