What Is a Keyed Alike System?

A keyed alike system means one key opens several different locks. The cylinders are rekeyed or supplied to match the same key.

When Keyed Alike Locks Make Sense

• Front and back doors on one key
• Shop, office, storeroom and shutter on one key
• Garage, side gate and outbuildings without a separate key for each
• Several rental properties managed with fewer keys

What Is a Master Key System? 

A master key system lets different people open different locks, while one master key opens them all. Each lock has its own key, and the person in charge holds the master key. Larger buildings can add a grand master key and extra access levels.

Example of a Master Key System 

A tenant’s key opens only their own door, while the landlord’s master key opens every door in the building.

Keyed Alike or Master Key: Which Do You Need? 

Keyed alike

• One key opens every lock you choose.
• Simple and convenient, you carry only one key.
• Best for homeowners, small shops, garages and gates.
• Anyone holding the key can open every lock, so access is all or nothing.

Master key system

• Each lock has its own key, plus a master key that opens them all.
• You can give different people access to different areas.
• Best for landlords, offices, schools, care homes, hotels and warehouses.
• Staff or tenants carry only the keys they need, while you or a manager keep overall control with the master key.

Frequently Asked Questions 

What is the difference between keyed alike and master key systems? 

A keyed alike system uses one key to open every lock in the group. A master key system gives each lock its own key, plus a master key that opens them all, so you get far more control over who can go where.

Can you make my existing locks keyed alike? 

Often, yes. Many cylinders can be rekeyed to work with one key, which can cost less than replacing everything. We’ll tell you if any locks need replacing.

How much does a master key system cost in London? 

The price depends on the number of locks, the cylinder type, and the level of security you need. We give a free, no-obligation quote after assessing your property, so there are no surprises.

Is a master key system suitable for landlords?

Yes. Landlords, letting agents, and HMO owners can access every property or room with one key, while each tenant holds only their own.

What happens if a master key is lost? 

Contact us as soon as possible. We can rekey the affected locks or reconfigure the system so the lost key no longer works.

Can you add more doors to the system later? 

In most cases, yes. A well-planned system can grow with your business or property portfolio.

Do you cover commercial and industrial premises? 

Yes. We fit systems for offices, shops, schools, care facilities, hotels, apartment blocks, warehouses and industrial sites across Palmers Green and North London.

Do you offer a free quote? 

Yes. We offer a free, no-obligation assessment and quotation. Call 07741 425051 to arrange it.
