Locks and Keys

Locks (Maintaining, Changing, and Installing)

We install, replace, and service locks. For safety and security reasons, locks that are not keyed off the master key system cannot be installed. If you need a lock that is not on the system due to unusual security requirements, you'll need to obtain approval from Public Safety and provide a copy of the key. Contact Public Safety at 212-305-8100 for more information.

For ID access or card reader repair, submit a request to Public Safety.

If you have been locked out from a non-residential space, call Public Safety at 212-305-8100. The locksmith is on site Monday through Friday, 7 a.m. to 3:30 p.m.

If you are in a residential space, contact the Office of Housing Services at 212-305-HELP (4357), option 2; after-hours, contact your front desk.


There is a charge for lock service based on an hourly labor rate, plus the cost of materials.

Key Duplication

We make keys for all academic and administrative departments and buildings. Report lost keys immediately to Public Safety at 212-305-8100.


Fees for key duplication range from $10 to $20, depending on the type of key. For security reasons, the duplication of keys by outside locksmiths is strictly prohibited.
