Rockshox Recon SL Solo Air gone stiff

My RS Recon SL Solo Air (came standard on my 2010 Scott Scale 50) has suddenly gone stiff. It won't compress or if I really lean on it it will only compress about 10mm. It all seemed to be working fine a month ago which was the last time I was out on my bike.
At first I thought it may be the lockout (the fork feels as though it's been locked out) but the lock/unlock cam on the top of the stanchion seems to move freely, i.e. it doesn't feel like it's stuck in the locked position.
Any ideas what the problem may be? Is it likely to be the 'lockout cartridge'? What else could make it go stiff like this?
The fork has never been serviced but I always wipe the stanchions down a lube the seals. I've seen the tutorials for servicing the forks and am quite comfortable with stripping the fork.
If I strip the fork down should I do a full seal replacement too while I'm at it or would that be wasting my money?

The damper has leaked oil into the lower leg - it will need servicing ie o rings replacing.0

Thanks for the reply ss. On further investigation, I let out the air in the fork and the fork does now compress although it's quite stiff and requires my weight on it to push it down. If I lift the bike the fork will extend again although slowly to about 50% of it's travel. I can then easily full the fork out to it's full length. It feels like there is a lot of stiction or friction on the stanchion or seals. So I'm not sure it's an oil leak otherwise the fork wouldn't compress even with the air out.
I have a fairly long ride planned tomorrow and won't be able to get a seal kit in time to service the fork. Is there anything I can do to check and clean / free up the seals without a new seal kit so I can use the bike tomorrow? If not I'll cancel. I don't want to be out in the middle of nowhere with a fork that decides to stop working.
Do you think it's more than likely the wiper seal on the stantion causing the resistance or and internal seal or impossible to say without looking? I'm just trying to establish where to start. Can the fork be stripped cleaned and reassembled without replacing the seals?0 -
Still sounds like some damper problem, maybe the lockout function is half closed. I doubt it is the seals, but only a full strip will find that out.0

OK thanks. I spoke to my LBS, they don't do the service but send the fork away and with August holidays around the corner advised against sending it now as it probably won't be back before September. He also wouldn't be able to get a seal kit for at least a week.
So it seems I'm stuck for the moment. I looked for kits in the UK but they won't send oils overseas. I can buy the seals but would have to source the oil locally. Is there anything special about the oil or is it just a standard synthetic oil of 2.5W and 15W?
Where is the best place in the UK to purchase the seal kits from and would you also buy the stanchion wiper seals? For some reason they are sold separately.0 -
I found TF tuned. They won't ship the oil outside of the UK. They do have the seals though on their own. Not tried Mojo. Will look them up. I'm shocked at how expensive a few 'o' rings and seals are.0

Plenty of kits on EbayI don't do smileys.

Are they having a laugh? Take it to another bike shop that wants your trade rather than fobbing you off. I have just seen you're not based in the UK but this is still a long turn around for a fork service0 -

I've seen kits on ebay from about £15, maybe the UK sellers will post to you?0

Use motorcycle fork oil (I use Yamalube), half the price and twice the volume of MTB specific oil. If it's good enough for a 160mph motorbike it's good enough for an MTB.
I've been using it for years with no ill effects.0
