Ordering Cover Lock Keys
For protection against unauthorized key duplication, the cover lock is a high-security
lock. Keys (see Figure 16) for these locks are a factory-restricted series and duplicate
keys are not available through normal commercial channels. The serial number of the
lock is stamped on each key. Make a note of this number. The additional key supplied,
and your note of its number, should be stored in separate secure areas.
If you lose the key, or it becomes faulty, a replacement key can be purchased from the
Illinois Lock Company.
