Overview

Electronic locks are battery operated which means the batteries need to be changed regularly. However, not all locks are equal in usage and priority of access. If a study room lock dies unexpectedly, it isn't nearly as problematic as the locks in the loading dock area. The schedule of maintenance takes these factors into consideration. Additionally, the Valley Library is not responsible for maintaining all of the electronic locks in the building. Some are managed by other groups. This page outlines:

Maintenance Schedule

Every 2 months

  • Both locks in the loading dock area (2711)
  • Currently the first week of odd numbered months

Every 3 months

  • Locks for all other staff areas
  • Currently scheduled the first week of September, December, March, and June.
  • Note that twice a year staff locks and the loading dock locks are changed at the same time.

September

  • Research room and study room locks are changed the first week of September.
  • This ensures the batteries are freshest during our busiest time of year, beginning of Fall term.
  • Staff areas and the loading dock locks are also changed in September which means every electronic lock should have the batteries changed during the first week of September.

Annual Summer Unlock

  • Every summer we use the Smart Time feature to set the 5th floor study rooms to automatically unlock during the day.
  • Patrons are not required to reserve 5th floor study rooms or check out the key card at the Circulation desk during the summer.
  • At the end of summer intersession, the locks are set to automatically lock again.

Battery Replacement

CM Series lock (old locks)

Supplies
  • Check-off form
  • Philips head screwdriver or cordless drill
  • 4 AA batteries per lock
  • Study Rooms Master key
Steps to replace batteries
  • The battery compartment is located under the interior latch, secured by four Philips head screws, one at each corner. 
  • Remove all 4 screws while carefully holding on to the back of the lock so it doesn't fall. 
  • Carefully pull the piece off of the door.
  • This is most easily done with the door closed. 
    • When you do this, you are locking yourself in the room. Don't freak out.
    • The piece you are removing will look like this.

  • The part remaining on the door will have a square hole that should have a peg with a spring on it. Sometimes the peg will fall out. Some of the doors are missing the spring.When you put it back in, make sure the rounded end is outward facing. 

  • Remove the old batteries and replace with new ones.
  • Fit the back panel back, being careful to line up the peg and spring. Then replace the screws. 
    • Take care to sink the screws properly; if you don't, the threads inside the panel will be stripped and the screw will not screw in completely. It may also cause damage to the panel.
    • A good trick is to put the screw in by hand, turn it counter-clockwise until you feel the screw slip into place. Then carefully turn the screw clockwise by hand a rotation or two to properly thread the screw.
  • Finally, pull on the handle to make sure that the latch engages. If it doesn't, remove the back panel again and check whether the batteries and the spring and pin are in correctly.
  • Record completion of door.
  • When all doors have been completed, record in table at the bottom of this page.
