[200q20v] closer...almost a cigar

This afternoon I bought a set of Channelock snap-ring pliers at Home Depot
(model #907). This is a "two-way" tool (for both internal or external
circlips) with a nice assortment of tips, and it's much better than what
I'd been using. With the new tool I could get the circlip off the lock
cylinder easily. With help from my wife--holding the flashlight--I verrrry
carefuly re-aligned the tiny "rack and pinion" so that the two half-teeth
matched up. But now I encountered a new crisis, which was that upon
re-installing the circlip retainer I found it had evidently become
"sprung-out" (stretched), and would not adequately grip the lock cylinder's
groove. It's barely holding on and would soon fall off with any real-world
use. So I may try re-bending the circlip to its original diameter diameter
and hope it doesn't just fatigue and break. But I'd much prefer use a
fresh one, so tomorrow I'll try to locate up a spare (or two) locally.
Well, what about the gear-teeth alignment--did I finally get that right? I
was able test it even though the door is apart. I used a block of wood to
hold the door-jamb switch closed. A successful test of the alarm system
activation is to hear that brief "beep" when the key is turned clockwise.
However my testing appears to have uncovered yet another problem. What I
found was that the lock only *sometimes* is able to properly arm the alarm,
but most of the time it didn't work. Hmm, so my careful alignment failed,
right? But wait....! Why had it become intermittant?
When I looked more closely at the plastic switch-housing (it contains the
little gear/microswitch assembly) I noticed that its white plastic cover
was very loose-- loose enough for the cover and its attached gear to wobble
when the key is turned. But if I pushed the white cover/gear firmly into
place with my finger while doing the beep "test"--it worked
fine--consistently, over and over again! Whenever I allowed the white cover
to lapse back into its "loose" position, the alarm activation (i.e. "beep")
would fail after a just couple of lock/unlock cycles.
My solution was to snugly wrap the little switch-case with some duct tape
and then with a length of thin stainless steel wire. This holds the
gear/cover tightly in place, and I think it should affect a long-term
"cure". Has anyone else experienced such looseness in that gear cover? It's
a pretty delicate little bit of plastic and it's no wonder that as it ages
and loosens it can throw off the alignment and screw up the switch
activation. Now, it's just a matter of getting a "fresh" circlip installed,
and I should be done. Phew!
