E36 sticking drivers door lock barrel

[beeeamer 0]

in the last few weeks the drivers door lock has started getting sticky when locking/unlocking the door with the key. i sprayed a bit of CRC in there which fixed it for a few days but started sticking again, so weekend before last i shoved some grease in there which fixed it but now it's sticking again after a week and a half.

it can require a bit of force to turn the key so i've started unlocking/locking using the boot or passenger door since they work sweet and i'm worried about snapping the key or damaging the lock.

any idea what would be causing this?

i think it's a sign to get an alarm with remote central locking haha

Hmmmm i had no problem with this, I always just dropped a tad of wd40 into all the locks about once a month to keep everything fresh.

You should not use a wet lubricant inside a lock barrel, will collect dirty and crap over time making it worse.

Best to use a dry lubricant like graphite dust. I got mine for a few bucks from Mitre10, made in Germany too!

yeah it was sweet until the constant rain started, just assumed it might have started to corrode a little bit inside maybe.

pretty sure dad's got some graphite dust, i'll try that next time i pop over
