Did you try sitting on the seat, or pushing down on the seat to lighten the load on the release mechanism ?

If this doesn't work, there are two Phillips head screws that hold the lock mechanism to the frame, it's a tight access area and you need something like a ratcheting 90 degree screwdriver to remove the screws .

Most likely they have never been off since the bike was built, so they will be a bit tough to get broke loose the first time .

If you're dealing with an R65 -and please consider including your bike model and vintage in either your question, a sig line or with your avatar- you'll have an easier time removing the seat lock box after pulling the rear fender.

You may reach the Phillips screw heads on the back of the lock box with a 90 degree driver, but getting enough pressure on 'em to break them loose will give you bloody knuckles. [smiley=furious3.gif]

Its probably off one of the hinges there are two small circlips on the end of the hinge pins if you can be bothered to fit the fiddly little buggers.
I have had this with mine and you need to be a bit brutal to release it, press the button while levering the seat up somewhere near the catch with a large screwdriver or tyre lever, it will release with out damage to the mechanism.

[size=13]"It's like deja-vu, all over again."[/size] - Yogi Berra

Another perfect weather day in North Texas so rode the R100S to deliver a prescription to my 87-year-old mum. Stashed my gloves under the seat, hung my helmet on the frame loop and locked the seat. First time I'd used the seat lock. You can guess, right?
The seat lock "locked" but would not unlock when I was attempting to head home. [smiley=furious3.gif]

So here's ATGATT Monte riding down the highway wearing his leather bike jacket but no gloves and the helmet's floppin' on the side of the bike. Not a pretty picture.

Spent the next two hours getting the seat open. Using HD tie downs to compress the seat did nothing but help me bend, then eventually, crack the key. Ain't that just swell.

With the LWB bike and some fender clearance, I was able to get a 90[ch730] screwdriver behind the lock box and remove the two screws. This took some time and did draw a little blood.

With the lock box off, I could access the small screw and lock ring that holds the lock set in place. This chore required a short, small, flat-blade driver, a mirror and a flashlight.

After that struggle, it was possible to push the locking bar away from the seat peg and open the seat. Whew...

Examination of all the parts determined that the lock itself is gerfunken. "Someone" -most likely my late pal and PO Steve- had the same issue. The lock was beat up and had marks that appeared to be from a vise! Totally hammered, it is.

The pot metal seat lock box itself is cracked and bent from previous exorcisms. None of the damage is visible when all is installed. Lucky me, huh?

So, for now, the lock is in the dumpster and the seat latch is functional. I had previously purchased a new key lock for the '81 R65 and they ain't particularly cheap. Think I'll just ride commando for awhile.

Really glad the problem did not occur with either of the R65s. Those SWB scoots have all but zero space twix lock box and fender. And removing the fender requires an open seat to access the hardware.

I'm feeling your pain, livingdeadhead.

thanks bud, been trying again today , solutions up to now are in no particular order, remove mudguard unscrew screws behind lock , cant access nuts of mudguard with seat on. 90 degree screwdriver, about 1" of  
space clearance , sit on seat press button , (how will it open i'm on the seat?) hit seat while pressing button ,(bad seat! how dare you not open!) .
funny thing is i was in the upholsterers with my old seat and they said the place i'd just picked my spares up from had them , rang , they had 1 near new £80.00 about what it would have cost for reupholstery. rang them with my problem they said 'drop the mudguard' and 'fiddle with it'! the only solution i know will work involves stanley knives , hack saws and crowbars , but i doubt if i'll get a refund .  >:(

Wondering if it's possible to remove the 2 hinge pin c-clips, slide the seat off the hing pins and working the seat peg latch/lock from there?  Possible?

I had a similar problem with the large seat peg that latches in the lock was ever so slightly bent causing a mis-alignment in the lock.

i think that would only work by bending the hinges, ive tried pulling it back but its about a 1/4 inch its got to move and the hinges are shall we say ,substantial !. i think my best option is to trailer it back to the supplier
say its not fit for purpose , take it back and gimme a refund! i think youre probably right about the pin alignment.

Only other advice I could lend is to have another body on the right side of the bike and either bumping the left side of the seat by smacking it with the palm of your hand, with the button depressed or pushing the left side of the seat with some force to the right trying to release the peg slot form the locking mechanism.

I feel your pain.  Let us know what develops and what the cause was - if you get that far.

I've had this happen too many times now not to have worked out a way out that works for me. Invariably the seat won't open because the seat is NOT properly on the two hinges ....one pin is just not in it's hinge hole! It is usually the front hinge hole. The pin is jammed on the side of the hinge. I take a large screwdriver to that front hinge and misaligned pin and wedge it a bit so that it goes into the hinge hole. All works then. I am paranoid now about closing the seat without an absolute confirmation that the pin is IN the hinge hole. WAPITA!
Why I don't put a circlip on the back pin??? Well it just keeps falling off and they are special circlips with a wedging-off lip that are hard to find for me. Also, the gas tank and battery come off easier if seat can open all the way up and over. Stays there better too...and won't just shut with a bang that usually ends up with the pin and hinge all messed up again!

So lesson...always use a strong flashlight to confirm proper alignment of pin and hole before shutting seat down!! It is one of my "arrrgghh" moments and usually happens when I am in a hurry.

Monte, now that you've taken the clasp off will you consider tracing a template for me?  (I told you it could be done!)

Just can't do it on an R65 SWB. No way on God's Green Earth to reach the lock set ring and screw without chopping up the rear fender.

I might advise livingdeadhead to yank the rear wheel and Dremel off the under-seat fender hardware to remove the fender, sans damage to it.
