Safe lock troubleshooting › Globaloks (Millennium Locks) › Globaloks ULIX (ring of keys around a knob)
The Globaloks ULIX is an electro-mechanical safe lock made by Millennium Locks Corporation. The keypad is a ring of ten number keys around a round knob, with PROG and END buttons and three small lights at the top. You enter a six-digit code, and then turn the knob to open the door. This guide covers how to open it (single, dual-control and time-delay versions), change your code, the batteries, what the lights mean, and the 10-minute lockout.

Is this your lock?
- A round keypad with a ring of ten number keys (0 to 9) around a knob in the middle. The word ULIX and a Globaloks badge are on the knob. A PROG button and an END button are near the top.
- Three small lights at the top of the keypad: red (hourglass), green (open padlock) and yellow (battery).
- On some versions the knob is replaced by a key cylinder (the ULIX-C models, with a Medeco cylinder).
- The lock comes in four bolt types: ULIX-1 (the bolt is pulled back by hand and goes out by itself after a short delay), ULIX-2 (pulled back and pushed out by hand), ULIX-3 (a dead-latching slam bolt) and ULIX-4 (a non-dead-latching slam bolt).
- It uses two six-digit codes. Depending on how it was set up, either code opens it (single user), or both are needed (dual control), and it may have a time delay.
How to open it
What you do depends on how your lock was set up. If you are not sure, try the single-user steps first.
- Enter your six-digit code. The red light comes on and the keypad beeps for each digit.
- After the last digit, the green light flashes.
- Within 5 seconds, turn the knob to pull back the bolt. After 5 seconds, the lock locks itself again.
Dual control (two codes)
- Enter the first six-digit code. The green light flashes and the keypad beeps.
- Enter the second six-digit code. The green light flashes once after the last digit.
- Within 5 seconds, turn the knob.
With a time delay (single user)
- Enter your six-digit code. The green light flashes after the last digit.
- The red light flashes every second during the delay. Wait for it to finish.
- When the delay ends, the green light flashes every second during the open window. Enter the same code again now.
- When the green light flashes after the last digit, turn the knob.
With a time delay (dual control)
- Enter one of the six-digit codes. The green light flashes after the last digit.
- Wait for the delay: the red light flashes every second.
- In the open window (the green light flashes every second), enter the second code.
- When the green light flashes, turn the knob.
- If a code is wrong, the red and green lights flash alternately and the keypad beeps.
- If you do not enter the code inside the open window, the lock locks again and you have to start over.
- The END button clears a partly entered code at any time.
- The time delay can be set up to 99 minutes, with an open window of up to 9 minutes.
How to change the battery
The keypad runs on two AA batteries. Millennium says they last about 3 years or 50,000 openings with alkaline cells, or 5 years or 75,000 openings with lithium cells. We recommend Procell alkaline. A flashing yellow light means the batteries are getting low.
- What the lock does when the battery is low: the yellow light flashes. If you ignore it, the lock keeps working for another 32 openings and then fails in the locked position. At that point, if you press any key, the yellow light flashes and the sounder beeps for 30 seconds.
- Your codes are safe: they are kept in the lock’s memory, so they are not lost when the batteries are taken out and replaced.
- The battery compartment is part of the keypad (in Millennium’s pamphlet picture it is a tray below the ring). Millennium’s instructions do not give steps for changing the batteries, so we are not guessing here. If you cannot reach them or the safe is locked and dead, call us and we will open the safe and replace the batteries.
How to change your code
Do this with the safe door OPEN.
Test the new code 3 times with the door open before you close it. If a time delay is set, wait for the delay to run first, and then open the door. Millennium says to change both factory codes to new numbers.
- Press the PROG button.
- Enter your existing six-digit code. The red light comes on.
- Enter your new six-digit code. The green light comes on.
- Enter the new code again. The green light goes off: the new code is set.
- Test the lock three times with the door open.
- You have 10 seconds to finish. If you take longer, or make a mistake, the red and green lights flash, the sounder beeps, and the lock goes back to your old code.
- Press END at any time to clear a partly entered code.
- Each of the two codes is changed by its own user, with that user’s own code.
What the lights mean
| What you see and hear | What it means |
|---|---|
| Red light on, keypad beeps for each key | Your digits are being entered. |
| Green light flashes after the last digit | The code was right. Turn the knob within 5 seconds (or wait for the next step if there is a delay or dual control). |
| Red and green flash alternately, beeps | A wrong code, or a mistake while changing a code. |
| Red light flashes every second | The time delay is running. |
| Green light flashes every second | The open window: enter the code now. |
| Yellow light flashes | The battery is getting low. Replace it soon. |
| Red and yellow flash alternately every 2 seconds | The 10-minute lockout is running. |
| Yellow flashes and the sounder beeps for 30 seconds when a key is pressed | The batteries are too weak to work the lock. |
Wrong codes
Three wrong codes in a row shut the lock down for 10 minutes. Further codes are ignored during that time, and the red and yellow lights flash alternately every 2 seconds. Wait it out before you try again.
If it still won’t open
The green light flashed but the knob will not turn
You have only 5 seconds after the code. If it will not turn, wait for the lock to relock and start again, and turn the knob right away.
The red and green lights flash alternately
The code was not accepted. Press END and enter it again, slowly. Three wrong codes start a 10-minute lockout.
The yellow light is flashing
The batteries are low. Replace them soon. The lock only keeps working for about 32 more openings.
The keypad beeps for 30 seconds and the lock will not open
The batteries are too weak to run the lock. Call us: we can open the safe and replace the batteries.
I forgot the code
Please do not keep guessing: three wrong codes shut the lock down for 10 minutes. Call us.
