Key Control Locks

Control Chart: Each order of key control locks comes with a paper control chart that contains the serial number and the corresponding combination numbers. A school’s complete charted system is kept on file by dudley®.

Even though a paper control chart is forwarded with each order, there are three (3) other options available to receive said data in an Excel-file:

  1. Diskette
  2. CD or

Refer to caption Electronic Control (EC) on our School Order Form under DATA for cost in relation to the above captioned option.

Lost Combination Retrieval

In order for us to be able to provide you with the lost combination number(s), we will require the serial number(s) of the lock(s) in question. However, only records for the last 10 years are available.

For your information, the serial number is engraved at the bottom of the lock or on the back of the lock for the DY1525 or DYA400K.


Our warranty on all serialized locks is two (2) years from date of purchase. Liability is limited to the replacement of our product only. The warranty does not cover damage resulting from mis-use or abnormal abuse.

All defective locks must be returned to us freight or postage prepaid (Collect shipments will not be accepted). Therefore, to reduce and avoid unnecessary shipping costs for locks beyond the guarantee period, we suggest that you first fax or e-mail the serial number of the defective locks to verify if still on warranty. Fax and e-mail address as follows:

Fax: 1-800-229-0081 e-mail:

Once your list has been verified, a Customer Service Representative will advise you which locks are still under warranty and how to proceed. Should defective locks need to be returned to our attention, we will provide you with a RA (Return Authorization) number which is required to be referenced on your school letterhead.
