For good reason they are locked files!
They are usually critical databases that programs will LOCK when in use so
they don't get corrupt
There are Many Programs that use this Extension
http://www.file-extensions.org/lck-file-extension
Depending on where you find them would be a good clue
on what program is using them.
If they are "GROWING" in a directory
and you think something is wrong.
It could mean that the program involved with them is either being shut down
incorrectly
or malfunctioning.
Depending on where the located, search out support for that application
and see if they have a specific newsgroup/support help
that others are having the same issue.
A great Program to help you "Clean up" things is
ccleaner.exe
http://www.ccleaner.com/
I hope this helps
