I have a boot issue, as in, I need to get into the boot!

I've got a 1985 w123 230E with original key. For a few weeks, I have found that I need to jiggle the key in the boot lock to get it to unlock. Tonight, I went to unlock it and they key will not turn at all. I've given it the WD40 and entirely too much time on my knees jiggling, wiggling, turning over the key &c but it just won't rotate in the lock at all.

The key is also a bit stiff in the driver's door lock but is working in the ignition without issue.

Vacuum system is working perfectly.


Is it just a case of the key being worn and a replacement will work just fine?

Many thanks in advance,

MA

That's why I am asking....the key is worn and the boot has been needed a bit of wiggling to get it to turn.

If it is a seized tumbler...how is it corrected?

Lube has been sprayed into it already before I posted.

My only solution is to order a new barrel? I'll try my local independent.

To try and open hold something that vibrates on the key, this can jiggle the levers so that they can drop down to the key profile

No, you can dismantle the barrel, sand, clean and lubricate it, if the fault with the lock is wear or dirt or corrosion then the lock can be brought back to working order again.

The door lock can benefit from the same treatment.

I meant if your locks tumblers were too worn. I've bought replacement tumblers for my other car's ignition lock - yet to fit them :Oops: - because I had problems actually turning the key. I've since remove the tumblers & filed them, but as the new tumblers were just a few quid delivered, I thought I'd treat it. ;)
