| Problem |
Probable Cause |
| 1. |
The outside knob and inside handle retract the latch when turned TOWARDS the door frame. (250/255 models only).
|
The spindle is positioned at the wrong angle. Refer to the code change instructions. Remove the lock from the door as shown in the instructions. On 255 locks ensure that the blue screw on the lever handle plate is in the correct hole. |
| 2. |
The knob will not turn after entering the original code.
|
The code does not match the card. Remove the lock from the door, turn the lock case upside down and check that the red tumblers correspond with the code on the card. NB: the 'C' tumbler is not coloured - but MUST start every code.
|
| 3. |
The knob will not turn after entering a newly changed code.
|
One or more of the code tumblers are the wrong way around. Re-read the code change instruction and check that the square notches on the tumblers face to the outside edge of the lock with the coloured tips on top.
|
| 4. |
The latch bolt does not move smoothly in and out.
|
The lock is installed incorrectly. Check that the lock is square on the door and positioned accurately over the latch. Check that the latch is positioned horizontally and parallel to the door surfaces. Check the door thickness against the spindle measurement. If the spindle is too long it may be trapped between the front and backplate. The dimensions marked on the spindle refer to the minimum and maximum door thickness for that spindle.
|
| 5. |
The outside knob turns after entering a correct code but does not retract the latch.
|
The spindle is too short for the door thickness. If the spindle is too short then it will not engage with both the outside knob and the inside handle at the same time, or it may slip out of one side after some use. The dimensions marked on the spindle refer to the minimum and maximum door thickness for that spindle. |
| 6. |
The outside knob turns freely without retracting the latchbolt.
|
The knob has been forcibly turned. Return the combination lock to Codelocks for free of charge repair. Be aware that someone has tried to gain entry by forcing the outside knob.
|
| 7. |
The inside lever handle does not return to the upright position after operating.
|
The lever return spring is broken. Call the Helpline for a replacement spring, free of charge. |
| 8. |
The latch does not engage and so the door remains unlocked after use.
|
The latch is not entering the strike. Your door or frame may have warped since the lock was installed. Check that the latchbolt is lined up with the strike aperture and adjust the position of the strike as necessary. Make sure the deadlocking plunger does not enter the aperture alongside the latchbolt.
