Safe lock troubleshooting › LA GARD (dormakaba) › LA GARD LGAccess 3900 (keypad in the handle)
The LA GARD LGAccess (3900) is a safe handle with the keypad built in. You enter a six-digit code on the keys in the handle, and then turn the handle to open the door. It works with LA GARD’s LG Basic (3765-2) and SafeGard (3260) electronic swing bolt locks. This guide covers how to open it, change your code, replace the 9-volt battery (it is behind the handle), what the signals mean, and the Manager commands for the LG Basic lock.

Is this your lock?
- A door handle with a keypad in it: two vertical rows of five keys (1 to 0), each with letters, and a small red LED. A small LG logo sits at the bottom of the handle. LA GARD’s cut sheet lists it in chrome, brass and black.
- It uses one 9-volt alkaline battery in a compartment on the back of the handle.
- It controls a LA GARD LG Basic (3765-2) or SafeGard (3260) dual-handed swing bolt lock, which is inside the door. You turn the handle to open the door. The LG Basic has a Manager and one User, and the code is six digits.
- If your keypad is a round keypad on the door and not a handle, see our guides for the 3000 / 3035 / 3125, or the 5715 / 5750 / 5750-K keypads.
How to open it
- Enter your six-digit code.
- The lock gives a double signal (the LED flashes and the unit beeps) to confirm the code is valid.
- Within 4 seconds, turn the handle to the open position.
- Pull the door open.
- An invalid code gives a triple signal (the lock signals three times).
- On a safe with more than one lock, LA GARD says the swing bolt lock must lock first.
How to change the battery
The handle uses one 9-volt alkaline battery in a compartment on the back of the handle. Change it at least once a year (we recommend Procell). Repeated beeping during an opening means the battery is low and needs to be replaced right away. The lock keeps its programming in memory even with the battery out.
- Open the safe door and keep it open while you work.
- With a ballpoint pen, push the tip into the hole at the bottom of the handle to pop off the black plastic battery cover on the back of the handle.
- Take off the cover and gently pull on the battery until it drops out of the handle.
- Unsnap the connector from the two terminals on top of the battery. Never pull on the battery leads.
- Snap the connector onto a new 9-volt alkaline battery.
- Gently push the battery and its leads all the way up into the compartment.
- Put the cover back on by sliding the top in first and then snapping the bottom into place.
- Test the lock several times with the door open before you close it.
- If the battery is too weak to open the lock, change it as shown above. You do not lose the code when the battery is out.
How to change your code
Always do this with the safe door OPEN.
Test the new code several times before you close the door. Do not use a birthday or other predictable number.
- Press 0 six times.
- Enter your existing six-digit code one time.
- Enter your new six-digit code two times.
- A double signal means the code is accepted. A triple signal means it was not, and the old code still works.
- If you make a mistake, wait 30 seconds and start again from the first step.
Signals
| What you hear / see | What it means |
|---|---|
| Double signal (LED flashes and the unit beeps) | The entry is valid or accepted. |
| Triple signal (three signals) | The entry is not valid or not accepted. |
| Repeated beeping and LED flashing while opening | The battery is low. Replace it right away. |
| Red LED flashing at intervals, keys do nothing | The 5-minute wrong-try penalty is running. |
Wrong tries
Four invalid codes in a row start a 5-minute delay. During the delay the LED flashes red at regular intervals (LA GARD’s LGAccess sheet says every 5 seconds, and its LG Basic sheet says every 10 seconds), and the keys do not respond. When the delay ends, two more invalid codes start another 5 minutes. Wait it out, and then enter the right code slowly.
Manager commands (LG Basic lock)
The LG Basic (3765-2) lock behind the handle has a Manager code and one User code. The Manager can add, disable, reinstate and remove the User. Do these with the door open. For each one, enter the Manager code and hold down the last digit until the lock signals with two sets of double beeps, then release.
- Add a user: press 1 (the lock signals twice), then enter the new User code two times. The lock signals twice after each valid entry.
- Disable a user: press 2. The lock signals once, and the user is temporarily disabled.
- Reinstate a user: press 1. The lock signals once, and the user is back.
- Remove a user: press 3. The lock signals once, and the user is permanently removed.
- If you make a mistake, wait 30 seconds and start again. A valid entry gives a double signal, and an invalid entry gives a triple signal.
If the lock is a SafeGard (3260)
The SafeGard 3260 lock has more features than the LG Basic: a second user, a time delay (delay 1 to 99 minutes, open period 1 to 19 minutes), time delay override, dual control, a silent alarm and a remote override signal. LA GARD’s sheet says those settings are made with an optional hand-held programmer, and the alarm and remote signals need an optional alarm box. If your safe has one of these turned on, call us rather than guessing.
If it still won’t open
It beeps over and over when I open it
That is the low battery warning. Change the 9-volt battery behind the handle.
I get a triple signal
The code was not accepted. Wait 30 seconds and try again. After four bad tries in a row you get a 5-minute delay.
It beeped twice, but the door did not open
You only have 4 seconds after the double signal to turn the handle. Be ready to turn it right away.
The keys do nothing
The battery may be dead, or the lock may be in the 5-minute delay. Change the battery with a fresh alkaline one, and wait out the delay. If it is still dead, call us.
I forgot the code
Please do not keep guessing. Call us and we will open the safe and sort out the lock.
