Key Control Locks

Note: this section is for School Administration only.

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, you receive said data in an Excel-file by email.

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

Find these by pulling up on the shackle and rotating the dial CCW and noting the range where the dial 'sticks' while still pulling up on the shackle. Identify if your master lock has a serial number. A serial number is 6 digits. If there are only 4 digits, it is a date code and not a serial number. The serial number may be located on the back or bottom of the lock.

Lost Combination Retrieval

Only serialized locks may have the option of 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 from the last 10 years MAY be 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.
