Lockwood 3572 Key Override Digital DX Lockset

The Lockwood Digital DX Locksets provide a mechanical method of keyless entry.

For extra security when under forced attack, the inbuilt clutching mechanism allows the outside knob to rotate without operating or damaging the lock.

The factory set 5 digit code is easily changed to any 4, 5 or 6 digit code using the code changing kit provided with each lock.

Lockwood Digital DX Locksets are designed to control access into commercial areas, especially when frequent combination changes are needed to maintain security.

As the digital lockset utilizes mechanical operation, electrical wiring is not required. Selected locksets combined with digital access pads provide keyless entry.
