Safe lock troubleshooting › Sargent & Greenleaf › D-Drive (Z02 2004 series and the multi-user / dual-control 2005 series)
The Sargent & Greenleaf D-Drive is an electronic safe lock where you turn the keypad itself to open the safe: you enter your code and then turn the round keypad ring clockwise about 70 degrees. A small yellow tab at the top of the ring is the clue. It has one 9-volt alkaline battery in the keypad. S&G has sheets for the Z02 D-Drive (2004 series, single user) and for the 2005 series multi-user and dual-control D-Drive. This guide covers how to open it, change your code, replace the battery, and what the beeps and lockout mean.

Is this your lock?
- A round keypad with a chrome ring that turns, with a yellow tab at the top and the S&G logo under the keys. There is no handle on the keypad: the ring is the handle.
- Codes are six digits or six letters and end with #. The keys have letters on them.
- Z02 D-Drive (2004 series): one user at a time by default, with a master code, an optional supervisor code and up to five user codes. 2005 series (S&G’s sheets call it the X03 D-Drive): multi-user or dual control.
- S&G lists the 6130-2XX and 6130-3XX keypads for these locks.
How to open it
- Make sure the keypad ring is turned counterclockwise to the stop.
- Press your code digits or letters in order, then #.
- Within six seconds, turn the keypad ring clockwise about 70 degrees, until it comes to a positive stop.
- Do not put any pressure on the safe handle until after the keypad has been turned. Then open the door.
- To re-lock, close the door and turn the keypad ring back counterclockwise to the stop.
- Each button press gives a beep and the keypad LED lights for a moment. A pause of more than 10 seconds resets the entry: start again from the first digit. Press * to clear a mistake.
- If the safe’s boltwork is pressing on the lock bolt, move the handle to the fully locked position, make sure the keypad is turned counterclockwise to the stop, and enter a working code again.
- If a time delay is on, a valid code starts the delay (3 short high beeps). The lock then beeps once every 10 seconds, makes 10 rapid beeps at the end, and you have the opening window to enter a valid code and turn the keypad.
How to change the battery
The D-Drive uses one 9-volt alkaline battery (we recommend Procell), housed in the keypad behind the ring. The lock does not forget your codes during a battery change, even with no battery in for a long time. Always change the battery with the door open. When the battery is low, you hear twenty consecutive beeps after you enter a code and the lock will not open until the battery is replaced. On the 2005 series you first get an early warning of five sets of two short, high-pitched beeps before it opens. Hold * for about three seconds (three chirps), then enter your code, to hear the low battery simulator (a different chirp) without a weak battery.
- Pull the yellow tab at the top of the keypad toward you slightly. It is not meant to come off.
- Carefully turn the keypad ring counterclockwise to the stop, then pull the ring away from its base far enough to see the battery compartment.
- Put your finger in the compartment and carefully pull out the battery cables, so the connector and old battery come out. Disconnect the old battery.
- Snap a new alkaline 9-volt battery onto the connector, lining up the terminals.
- Carefully slide the battery behind the keypad into its cavity. Make sure it drops all the way to the bottom.
- Tuck any extra wire into the cavity so it cannot be pinched between the ring and the base.
- Push the ring back against the base and turn it clockwise until the yellow tab snaps back into place.
- Check the lock at least three times with the door open before you close it.
How to change your code
Always change codes with the safe door OPEN.
Wait for each set of beeps to end before you press the next key. If you hear a long continuous error beep during a change, you made a mistake: start the steps over. The old code is kept. Check the new code at least three times with the door open. The factory master code is in S&G’s sheet and we are not printing it here.
Z02 D-Drive: change your own code
- Press 3 3 *.
- Enter your current code and #.
- Enter your new six-digit code and #, then the new code again and #.
2005 series (multi-user and dual): change your own code
- Press 2 2 *.
- Enter your old code and #, then your new code and #, then the new code again and #.
- A user cannot delete their own code. Master and supervisor code holders add and delete other codes (that is administrator-level, so call us).
- Do not use birthdays or other personal data as a code.
Beep patterns
| What you hear | What it means |
|---|---|
| One beep and an LED flash with each key | A key was accepted. |
| 3 short high beeps | A code was entered to start a time delay. |
| 1 short high beep every 10 seconds | The time delay countdown is running. |
| 10 short high beeps | The time delay is finished. Enter a code now. |
| 2 short high beeps every 6 seconds | The opening window is running. |
| 1 long continuous beep | An incorrect or incomplete code. |
| 2 long continuous beeps | A code was entered during a penalty lockout. |
| 5 sets of 2 short high beeps before it opens | The battery is getting low (2005 series). |
| 20 short high beeps, lock does not open | The battery is too low for the lock to work. |
| 1 low/high beep sequence | The bolt extended: the lock is locked. |
Wrong-code lockout
Z02 (2004 series): four incorrect codes in a row shut the lock down for five minutes. Pressing any button during the lockout resets the timer to the full five minutes, so keep your hands off the keypad. 2005 series: five incorrect codes in a row shut it down for ten minutes, you hear two long error tones if you try a code, and button presses do not affect the timer. A wrong programming sequence can also trigger the lockout. Wait it out.
If it still won’t open
It beeps but will not open
Check that you turned the keypad ring (clockwise, within six seconds) after the code. The battery may also be too weak for the solenoid: replace it with a fresh 9-volt alkaline battery. If the boltwork is binding, move the handle to the fully locked position, turn the keypad counterclockwise to the stop and try again.
No sound at all when I press keys
Dead battery is the most likely cause. Replace it (steps above).
It seems locked out
If it gives a long error beep on everything, it may be in penalty lockout. Do not touch the keypad for the full time (5 minutes on the Z02, 10 on the 2005 series), then try your code.
I forgot the master code
Please do not keep guessing: wrong codes start a lockout. Your safe’s maker may have a reset code for it. Call us.
