Quincy House is replacing the striker plates on all doors in its new wing today after the discovery Wednesday that door locks were defective.
House Superintendent Carmen Levesque said yesterday the problem arose because striker plates on the doors were too large for new locks.
When Quincy House replaced its locks several years ago, he said, the old strikers remained on the doors. Locks were not fitted and therefore insecure, Levesque said.
Stephen S.J. Hall, vice president for administration, said there was a thorough investigation of locks at the University two years ago. He said he was "surprised" to hear of the faulty locks at Quincy.
Levesque said he did not know whether the increase of theft in recent years was due to the defective striker plates or to students leaving doors unlocked.
