Hi again guys,
I've had to start a new topic for this, because a couple of days ago I posted the same message under the old topic and it didn't go to the top of the group, so it's doubtful that anyone would see it (it was several pages down).
Anyway, to recap, we have a dual cylinder, automatic Ideal Security vertical deadbolt (Superguard?) that we purchased in ~1980. Unfortunately, we have lost the piece of wire and the manual that were supplied with it that give the instructions for how to remove the lock.
My dad and I have tried Bob DeWeese's suggestions for using a piece of wire to remove the lock, but unfortunately we've had no luck at all. We just can't seem to find anything inside for the wire to latch onto, and it's virtually impossible to shine any light in there to see what we're doing. Joe Kesselman suggested that there may be a retainer inside that needs to be pressed down while turning the key all the way in either direction, but we can't find this either.
I don't know how to post pictures into these newsgroups, so I've hosted the pics myself and have included the links below. I apologise for the quality, as the only digital camera we have is the one in my phone :(of the lock of cylinder (interior of house), showing the holes where the wire is inserted. Note that the top hole is half covered, and this is the same whether or not a key is inserted. In this picture, the bottom hole is fully covered, as it is only uncovered when the key is turned to a certain angle. picture as above, except the key is inserted and turned to reveal the bottom hole. The top hole is still half covered as above. of lock and handle from outside the house. of entire lock from the side of the door. Note that the metal ball is missing (round hole in the middle of the picture). This used to act like a catch so the door wouldn't swing open by itself when it wasn't deadbolted. don't know if this is in fact called a striker plate, but it is the part that the lock latches into when the door is shut. view of the "striker plate". Note that our door jam is very thin - I'd say less than an inch. piece of wire that dad made up to try and get the lock off :) This is *not* the original that came with the lock. We have been inserting the left end into the lock.
If anyone could lend us a hand with specific instructions on how to get this lock off, or even a scan (or hyperlink to) of the inside of the lock, it would be much appreciated. We have tried pretty much everything we can think of to get it off so far, other than actually breaking the lock :)
We also don't know which hole we are supposed to be putting the wire into. I would have thought it would be the top one, since half the hole (is this possible? :P) is never covered. However, my dad thinks it is the bottom hole, since the entire hole is exposed when the key is turned to a certain angle. How far do we insert the wire, and approximately where (and what) are we supposed to be "grabbing"? Thanks in advance for your help,
