Many members sharing one suite

Why shared offices are a different lock problem

An ordinary office has a small, stable group of people who need access. A coworking space or shared suite has a changing crowd. Members join, leave, pause and return. Some need round-the-clock access, others only business hours. Guests, cleaners, couriers and building staff also need to get in at times. Each of these groups has to be handled in a way that is secure, fair and workable for the operator who manages it.

The classic problem is key sprawl. Every time a metal key is handed to a new member, there is a chance that a copy is made, that the key is lost or that it is never returned. After a year of turnover, no one knows how many working copies exist. The operator faces a choice between living with that uncertainty and rekeying often, and rekeying can be disruptive and costly when many doors and members are involved.

This is why many shared offices move toward electronic access, where a person's credential can be added or removed without touching the lock. Even so, mechanical locks remain part of the picture, at suite doors, storage rooms, private offices, meeting rooms and cabinets, and they need a thoughtful plan too. This page walks through the main decisions.

Who needs access, and to what

Before choosing any hardware, map out the people and the spaces. A simple table, written down, saves a lot of confusion later. List the groups: full-time members with private offices, hot-desk members, day-pass visitors, staff and operators, cleaners and maintenance, building management and emergency responders. Then list the spaces: the building entrance, the suite door, common areas, meeting rooms, private offices, storage, server or network closets, supply rooms and the manager's office.

For each group and each space, decide whether access is needed, during which hours and for how long. A day visitor may need the front door and the common area for a few hours and nothing else. A private-office member may need the front door at any hour and their own office door at all times, but not other members' offices. A cleaner may need all common areas after hours but no private offices.

This map becomes the specification for the lock system. It tells you how many different levels of access you need and which doors need to be individually controlled. It also reveals where a simple lock will do and where an electronic system is worth considering. A technician can use it to suggest realistic options and to explain what each would involve. Our guide on access control planning goes through this process step by step.

Member access options

There are several common ways to give members access, each with trade-offs. A short summary helps you compare them:

• Metal keys are simple and need no power, but they are hard to track and expensive to change when a member leaves without returning one.
• Keypad entries use a PIN, which can be changed quickly, but a PIN can be shared or watched, so it needs regular changes and clear rules.
• Proximity cards and key fobs are issued to individuals, can be deactivated individually and can leave a record of use, but they need a reader and a management system.
• Phone-based credentials let members use a mobile device, which reduces lost cards but depends on the system and on members having compatible phones.
• Combined approaches use electronic access at the suite entrance and mechanical locks on interior offices, which is common and often practical.
• Every option needs a plan for power loss, lost credentials and emergency exit.

Rotating PINs and shared entries: benefits and limits

Many small shared spaces use a keypad at the main door with a PIN that is changed from time to time. It is simple and inexpensive, and it avoids handing out metal keys. It is also easy to misuse. A PIN given to one member can be passed to a friend, written on a note or watched by someone standing nearby. Once it has been shared, there is no way to tell who used it, and there is no way to remove one person without changing the entry for everyone.

If you use a shared PIN, build in a schedule for changing it, a way to tell members promptly and a rule that members must not share it. Change it whenever a member leaves, whenever you suspect it has leaked and at regular intervals. Remember that frequent changes create a communication burden, and members who are inconvenienced may write the new number somewhere visible.

Individual PINs or credentials, where each member has their own, solve the sharing problem and make removal clean. If your system supports it, they are generally a better choice for any space beyond a very small group. A technician can explain which hardware supports individual entries and which does not, and what it would involve to move from one to the other.

Private offices, meeting rooms and storage inside the space

Inside a coworking space, individual rooms need their own locks. Private offices are often rented to a single member or a small team, and the member expects privacy and security for their equipment and documents. Meeting rooms are shared and typically need either no lock or a booking-based arrangement. Storage rooms, supply cabinets and server closets need locks that restrict access to authorized staff.

For private offices, it is common to fit a lockset that can be rekeyed or reconfigured when the tenant changes, so a new member does not inherit access held by the last one. A keyed lock whose cylinder can be changed relatively quickly is practical here. Some operators use a master key system so that staff can reach every private office when necessary, while members only hold keys to their own. Our guide on master key systems for business explains how this works and what to watch for.

Cabinets and desks inside shared space also deserve thought. Members often keep documents and equipment in lockable furniture, and the operator should decide who holds the keys and how they are tracked. See our page on filing cabinet and desk locks for more on this.

Turnover: what to do when a member leaves

Every time a member leaves, the operator needs a routine to close the loop. Credentials should be deactivated or collected, keys returned and counted, and any shared PIN changed if the member knew it. For private offices, the lock should be rekeyed or its cylinder changed if there is any doubt about whether all keys came back.

The routine should be written down and followed consistently. A short checklist for staff avoids the common situation in which a member leaves, a key goes missing from the log and no one acts because it seems minor. Over time, those small gaps accumulate into a real security problem. Record who holds which keys, who returned them and when. Keep that record in a place that can be audited.

Plan for the cost and scheduling of rekeying in advance. If you know that private offices are turned over often, ask a technician about locks that can be rekeyed efficiently, and discuss how many offices can be handled in a visit. For multiple units, our guide on property management lock turnover offers a similar framework that can be adapted for shared offices.

After-hours access, safety and exit requirements

Many coworking members value access outside business hours, and that raises security questions. Think about who can enter at night, how entry is recorded, whether the building has its own security and how members are expected to behave when alone in the space. Locks are only one layer, and cameras, lighting and clear policies add to them. Our guide on securing a business after hours covers these related points.

Exit is as important as entry. People must always be able to leave quickly in an emergency, so doors on routes of escape must not be locked in a way that traps anyone inside. Local fire and life-safety rules govern which hardware is acceptable on exit doors, and an operator should confirm requirements with the building owner or the appropriate local authority before changing hardware. We do not give legal advice, and rules differ by building, but the principle is that security must never prevent safe exit. Our page on magnetic lock and fire safety basics describes some of the issues involved.

Also think about power failure and system failure. If an electronic system loses power, what happens to each door? Does it stay locked, unlock or fall back to a mechanical key? The answer should be chosen deliberately for each door, not left to the default of whatever hardware was installed.

Working with the building, the landlord and the lease

Coworking operators usually lease their space from a building owner, and the lease may limit what changes can be made to doors and locks. Before replacing hardware, check what your lease says, and whether the building uses its own master key system that your locks must fit into. Some buildings require that the landlord keep keys to every suite, and changing the lock without coordinating with them can lead to a dispute.

In multi-tenant buildings, the entrance doors and common areas are usually controlled by the building, and your authority extends to the suite door and the interior. Ask building management who approves lock work, what hardware is acceptable and how keys are tracked. Put approvals in writing. A technician will often ask who is authorized to request the work, and having documents ready speeds the process. Our guide on commercial authorization and key records explains what is typically needed.

Good communication with the landlord also helps in an emergency. If a lockout or a security concern happens after hours, everyone should know who to call and who has authority to approve action.

What a locksmith visit for a shared space looks like

A visit usually starts with a conversation about how the space works: the number of doors, the groups who need access, the current locks, the problems you are having and what you hope to change. The technician looks at the doors, the frames and the existing hardware, and asks about the building's rules and your lease.

From there they can explain realistic options, whether that is rekeying key doors, adding a keypad or reader to the entrance, installing individually keyed locks on private offices or planning a staged project over several visits. Quotes are given by phone, and a larger or more complicated project needs an on-site visit, with the service call charge explained on the phone before dispatch.

Have these ready before the visit: a list of the doors and their purposes, a note of the current keying arrangement and any key records, your lease or the contact details of the building manager, and a note of who is authorized to approve the work. If you would like to talk through a shared office or coworking space, call and describe it, and we can explain how a plan might be built.
