Care & Maintenance Advice

Mortice Lock, Key in Knob & Key in Lever Locks

Lock Mechanisms

At twelve (12) monthly intervals, the internal lock mechanism should be lubricated by an aerosol lubricant.

Cylinder Mechanisms 

Under no circumstances should any fluid or aerosol lubricant be used in the cylinder mechanism. Use only Kaba Cleaner for lubrication and cleaning.

In harsh environments it is recommended to maintain the cylinders on a six monthly cycle or as required. The procedure is to spray Kaba Cleaner into the keyway and insert and withdraw key three times. Wipe the key blade clean to remove any debris that may have been in the keyway.

Latchbolt Mechanisms 

At twelve (12) monthly intervals, the internal latchbolt mechanisms should be lubricated by an aerosol lubricant.

In highly corrosive environments it is recommended that the spindles and cams should be sprayed with a lubricant or smeared with white lithium grease for protection when servicing locks.

External Knobs, Levers and Roses 

All external lock components should only be wiped over with a soft damp cloth. In the case of Satin Stainless Steel or Satin Chrome Plate, a gentle abrasive cloth/sponge may be used to remove ingrained grit.

For soft finishes such as Antique Brass, Architectural Bronze, etc. under NO circumstances should any cleaning product be used. The cleaning product may contain solvents which may damage the protective coating. Window cleaning solutions are some of the worst offenders.

These finishes should only be wiped with a soft cloth and then polished with a silicone based spray. This should be done approximately every two (2) months. In the case of Oil Rubbed Bronze, instead of a silicone based product, use “Furniture Oil” or similar.


Door Closers 

At twelve (12) monthly intervals, the fixing screws from the closer shoe (bracket) to the frame and the closer body to the door should be tightened. Also, in the case of adjustable arms, the adjustment screw on the arms should be tightened.

At any time during the closer life, the closing cycle adjustment valves can be varied to best suit the working environment of the door. If however it is constantly necessary to increase the closing speed or the closing force because “the closer seems to be slowing down”, then we recommend that the door hinges be examined as they may be worn and causing ‘binding’ and thus overstressing the closer.

If the closer cycle valves are adjusted, open and close the door at least four (4) times to allow the valves to “seat” themselves in their new position. If the cycle is still unacceptable, commence the full procedure again.


Exit Devices 

At twelve (12) monthly intervals the following maintenance should be followed:

  • All fixing screws should be tightened
  • All strikes should be checked for correct alignment
  • Internal mechanisms need to be lubricated with an aerosol lubricant
  • External surfaces need to be treated as stated in (knob, levers and roses)
  • Hinges should be checked for ware as this may cause misalignment of the latch



When in environments at high risk of airborne salt deposits such as a coastal areas, dirt and grime build up and external applications. It will be necessary for maintenance to be undertaken in one (1) month intervals for all products. Kaba Australia also offers an optional ocean front coating to avoid these situations.
