I've got a friend who bought a house with window lock pins installed. He has
no key or wrench to remove the pins so they can open the windows. The pins
(or screws) have a round head except for one side which is flat. Imagine a
hex-head bolt with only 1 flat side instead of 6. I'm trying to help but I
don't know where to get the key. Home Depot, Lowes, Ace, all have different
versions of these security pins - none of which match the type described
above. Ace has a hex head screw/pin. Lowes and Home Depot have pins with a
key you use to pry the pin out. Where would one get a key/wrench which could
handle this semi-circular head? The pin/screws are recessed and can't be
reached with a regular pair of pliers. Ideally a key would work (like a gas
starter key) but it has to match the contour.
Their realtor couldn't locate the key and the prior owners aren't to be
found. The house was purchased from the bank as a foreclosure. There must
be a wrench/key which will fit this semi-circular bolt head. Any further
Get a metal rod that's exactly the same diameter as the screw-head,
and a few inches long. Grind the end, leaving a nub that just fits
the flat-spot on the screw-head. Find a metal tube that this
rod JUST fits inside, which will therefore fit over the screwhead.
Glue, or screw the rod inside the tube, flush with the end, or
just bend the entire assembly to keep them from twisting relative
to each other.
It's not a tumbler key so I didn't think to suggest a locksmith. Anway we
solved the issue. Using a pair of needle nosed pliers we were able to get
enough of a grip on the semi-circular head to unscrew it. We replaced all
of these locking screws with screws which had regular hex heads and a
matching hex key. Thanks anyway.
