How to Maintain a Master Key System

04/21/2015 Back To Blog

All apartment buildings, most commercial buildings and large residential properties have a master key system. It is designed to keep the level of security high and to provide fast lockout resolution. In order for this system to work effectively at all times, it must be maintained properly. Find out how to provide effective maintenance.Provide Care to All Components

Locks are fixed and replaced by expert locksmiths


Perform Thorough Check

Confirm the presence of all keys and evaluate their condition - The check must cover the grand master, master and sub-master keys. Make sure that all people who have such keys have a spare one as well. It is best if the change keys are covered too. If necessary, resort to new key cutting without delay. The keys must be checked for dullness, deep scratches, deformation and all other signs of damage and wear and tear. Repair or replacement must be provided timely.

Inspect all master keyed locks - The inspection should cover the cylinder, latching mechanism and strike plate. You have to watch out for scratches, chips, dents and deformations. Look closely for loose components and especially for loose bolts. Knobs must turn easily. The handles should waggle a bit when shaken gently.

Provide Care to All Components

Clean locks and keys - You should use a solution made from liquid detergent dissolved in warm water. Avoid using cleaning products as they may have corrosive compounds. Use a soft sponge for dirt removal. It will not cause scratches when you rub the surfaces. Rinse the items with clean water and dry them with microfiber cloth. Our experts in Egham suggest that you use only the mildest and sagest rust remover and solvent, if necessary.

Provide proper lubrication - All master locks should be lubricated with graphite lubricant which is especially designed for such devices. Make sure that the applicator is thin enough for the keyholes. Apply lubricant into the keyholes of cleaned locks only. Spread a tiny amount of it on the cylinders of external locks to lower the risk of freezing.

Replace and tighten bolts - This is essential for keeping door lock cylinders and strike plates securely in place. If strike plates have to be changed, you should consider ones which are held by four bolts rather than the traditional ones which use two bolts. The four-bolt units tend to be more reliable and durable.

If master system locks or keys have to be replaced, this must be done without delay so that the optimal level of security is restored in the fastest possible manner.
