Ignition Lock Lubrication

Apologies for what is a very basic question but ......

I can't recall ever having had to lubricate the ignition switch/lock on my maxiscooters.
The Crowman is becoming a bit reluctant to take the key, possibly because it stood for nine months and is now in a slightly damper climate.

I have a tube of graphite dry lubricant. I've used it on ordinary locks - doors, padlocks and so on but I want to check that it's okay to simply squirt some in where the key goes.

The following link is to the actual product which is sitting on my PC desk on front of me.

Thanks in advance.

Yes, that’s the stuff. WD-40 will only invite tumbler pins to gum up. Graphite powder is the way to go.

Thanks, Tim.
I need reassurance these days; I think it's an 'Age' thing.

Out of the blue last month the key would not turn the ignition/switch lock . Tried every delicate, jiggle and wiggle maneuver with the hand and key , nothing . A quick puff of the magic graphite powder , and it functions as should .

3rd for the graphite. The lock sits vertical and can get moisture etc. in it. A liquid lube can gunk up, not a good thing.
