Why access control is really a people question
Most owners start this topic by asking which product is best. A better first question is who needs to get through which door, and how often that list of people changes. A dental office with six staff and a cleaning crew has a very different answer than a self-storage office, a restaurant with high turnover, or a small warehouse with delivery drivers arriving at odd hours.
Every access method is a way of recording a decision: this person may enter this door at these times. A mechanical key records that decision once, at the moment it is cut, and then loses track of it. A keypad records it as a shared number that anyone can pass along. A card or phone credential can record it per person, and some systems keep a log of use. None of these is automatically better. Each fits a different pattern of trust, turnover and budget.
In South Florida there is an extra layer. Many commercial spaces are leased, and the lease often says who may change locks, who must hold a copy of every key, and whether the landlord needs to be told. Before any hardware changes, confirm that the person asking for the work is the owner, the property manager, or a tenant with written permission to alter the door. A reputable locksmith will ask about this on the phone, and that question is protecting the business, not slowing it down.
Mechanical keys: simple, familiar, hard to track
A keyed cylinder is the baseline. It needs no power, has no software, and a skilled technician can service it on the spot. In humid, salt-influenced coastal air, a well-maintained cylinder often outlives electronic parts that sit in the same door. For a small office with a stable team, a keyed deadbolt or lever lock can be entirely reasonable.
The weakness is accountability. A key can be copied at a hardware counter without anyone's knowledge, and when a person leaves, there is no way to cancel that one key short of changing the cylinder. Businesses with real turnover end up either rekeying often or living with unknown copies in circulation.
- Good fit: stable teams, low door count, owners who keep a written key list.
- Poor fit: high turnover, shared spaces, doors used by outside contractors.
- Upgrade path: restricted keyways, which limit unauthorized duplication to the supplier that holds the blank records.
- Always pair keys with a simple sign-out sheet, even if it is just a notebook kept by the manager.
Keypads and shared numbers
A keypad lock lets people enter a number instead of carrying a key. The appeal is obvious: nothing to lose, nothing to copy, and the number can be changed from the door in minutes on most models. For a back door used by a rotating crew, that convenience is real.
The honest limit is that a shared number belongs to everyone who has heard it. If a former employee still remembers it, the door is effectively still open to them until someone changes it. Keypads also show wear on the most pressed buttons, and in strong sun the faceplate can fade or become hard to read. Treat a keypad number the way you would treat a key: write down who knows it, change it when someone leaves, and avoid obvious sequences.
Some keypad models support individual user entries instead of one shared number. That makes it possible to remove one person without disturbing everyone else. If you are comparing options, ask specifically how many individual entries a model supports and how it behaves when batteries run low.
- List everyone who currently knows the number.
- Decide who truly still needs it.
- Change it on a schedule your manager can remember, and always when someone leaves.
- Keep a mechanical override key in a controlled location in case batteries fail.
Card, fob and badge systems
Card and fob systems assign a credential to each person. If one is lost, the office deactivates that card and nothing else has to change. This is why they are common in medical offices, multi-tenant buildings, and larger retail or industrial spaces. Many also record which credential opened which door and when, which helps resolve disputes about who was in the building.
The tradeoff is infrastructure. A reader at the door, a controller, wiring or a network connection, and a power supply are all parts that can fail. During storm season, power interruptions are a normal planning item in Broward and Palm Beach, so ask what the door does when power is lost. Some strikes unlock when power fails for life safety reasons, and some stay locked. The right behavior depends on the door, the building rules and how people exit.
Exit rules matter more than entry rules. A person inside must be able to leave without a key, a card or insider knowledge. Panic hardware and egress requirements are set by the local fire and building authorities, so any change that touches a path of exit should be checked with them rather than guessed at. A locksmith can describe options but the final decision belongs to the owner and the authority having jurisdiction.
Phone and app-based credentials
Some newer systems let staff open doors using a phone. Credentials are issued and revoked online, which suits a manager overseeing several sites. The benefits are fast changes and detailed records. The cautions are reliance on accounts, passwords and service plans that must be maintained, plus staff who may not want work software on personal phones.
Before choosing this route, ask who owns the account. If an installer or a former manager set it up under a personal email, the business can be locked out of its own system. Account ownership should sit with the company, with at least two authorized administrators, so one departure does not create a crisis.
Also ask about the fallback. Phones die, apps fail to update, and networks drop. A door that depends entirely on a phone should still have a plain mechanical or card-based backup that the manager controls.
Comparing the options side by side
The table below is a general comparison, not a recommendation for any one building. Real choices depend on door type, frame condition, how many people use the entrance and what the lease allows. Quotes for any of these are given only by phone, and complicated installations need an on-site visit so the technician can see the door, the frame and the power situation. For larger sites with many doors, see also master key systems for businesses, and for exit hardware read about panic bars and exit devices.
| Method | Strength | Main weakness | Typical fit |
|---|---|---|---|
| Mechanical key | Simple, no power needed | Copies cannot be tracked | Small stable teams |
| Shared keypad number | Nothing to lose or copy | Number spreads by word of mouth | Back doors, small crews |
| Individual keypad entries | Remove one person at a time | Needs careful setup and upkeep | Offices with moderate turnover |
| Card or fob | Per-person control and records | Needs power and controller | Medical, multi-tenant, larger sites |
| Phone credential | Remote changes, strong records | Depends on accounts and phones | Multi-site managers |
Humidity, salt air and heat on access hardware
South Florida is hard on electronics. Humidity gets into housings, salt air corrodes contacts and screws near the coast, and direct sun warms exterior readers beyond what many indoor-rated parts expect. When a reader starts to misbehave after a wet week, moisture is often the first suspect. A technician will usually check seals, gaskets, cable entry points and whether the product was rated for outdoor use at all.
Doors themselves move with the climate. Wooden and metal doors swell, sag or rub, and a latch that no longer lines up with the strike can make an electronic lock seem faulty when the real problem is alignment. A good technician checks door fit before blaming the electronics, and that is one reason an on-site visit is often needed before anyone can responsibly quote a repair.
Regular upkeep usually costs less than an outage, but we do not quote anything on this page. What you can do is keep a simple routine: look at each reader monthly for cracks or lifted seals, test the door after storms, and keep spare batteries on hand for battery-powered units.
- Check that exterior readers are rated for outdoor use.
- Look for green or white corrosion at screws and cable entries.
- Confirm the latch lines up with the strike when the door is closed normally.
- Test the emergency exit path after every storm.
Authorization: who may change an access system
Changing who can enter a commercial space is a serious act. A responsible locksmith will not reprogram a keypad, remove a credential or rekey a door for someone who cannot show a right to do it. Typical proof includes a lease or ownership document, a government photo identification that matches the name on that document, or a written authorization from the property manager. The point is to stop a former partner, an angry ex-employee or a stranger from locking out the people who legitimately run the business.
In shared buildings, authority is often split. A tenant may control the suite door while the landlord controls the building entrance and holds a master key. If a tenant wants to replace a lock with a card reader, the landlord may need to approve it, may want a key kept for emergencies, and may require that fire and life-safety rules be respected. Ask before the work, not after.
If you are unsure who has authority, say so on the phone. Honest uncertainty is easier to resolve than a job that stalls at the door. Our overview of locksmith authorization for businesses lists the documents that usually settle the question, and after-hours access planning covers who should be reachable when a door fails at night.
Questions to settle before choosing a system
Before calling for a quote, write short answers to the questions below. They make the phone call faster and help the technician understand what to bring. They also protect you from buying a system that solves the wrong problem.
- How many doors need control, and which are exits that must always open from inside?
- How many people use each door, and how often does that list change?
- Do you need a record of who entered, or only a way to keep strangers out?
- What happens at the door when power fails, and is that acceptable?
- Who owns the system account or master credentials, and who is the backup administrator?
- Does your lease or association require landlord approval, a key copy, or a specific contractor?
- What is the condition of the door and frame, since a sagging door defeats good hardware?
What happens when you call
When you call about access control, expect questions before any commitment. The dispatcher will ask about the type of business, the door, what is happening, and who you are in relation to the property. You will be asked to confirm you have authority to request the work. Quotes are given only by phone, and anything more involved than a simple repair needs an on-site visit so the technician can examine the door, the frame and the electrical situation.
There is a service call charge for sending a technician, and it is explained on the phone before dispatch. The company does not promise arrival windows for any specific moment or place. If your situation is urgent because a door will not secure the building, say that clearly, and ask what temporary measures are safe while you wait. If anyone is in danger or a crime is in progress, call 911 first.
Have these ready: the business name, your role, the door location, a photo of the lock or reader if you can take one safely, and any lease or management document that shows authority. When you are ready to talk through your building, call and describe what you need.
Questions people ask
Is a keypad lock more secure than a key?
Not automatically. A keypad removes the risk of a lost or copied key, but a shared number can spread to people who should no longer have it. Security depends on how the number is managed, how often it changes, and whether former staff are removed promptly. A well-managed key system can be stronger than a neglected keypad, and the reverse is also true.
Do card systems work during a power outage?
It depends on the design. Some electric strikes stay locked when power is lost, and some release, depending on the door and exit rules. Many systems include a battery backup for a limited time. Ask what the door does during an outage and whether a mechanical override exists. The technician can explain the options for your specific door during an on-site visit.
Can my tenant change the lock on a suite without telling the landlord?
Often not. Leases commonly require landlord approval for lock changes and may require that the landlord keeps access for emergencies. Doing the work without checking can create a lease problem and a safety concern. A locksmith will usually ask about authorization, and a written permission from the property manager makes the process smoother.
How much does an access control system cost?
Pricing is given only by phone, never on a web page. The answer depends on how many doors, what type of door and frame, whether wiring exists, and what features you want. Complicated installations need an on-site visit first. There is a service call charge for dispatch, and it is explained on the phone before anyone is sent.
What should I do if an ex-employee still knows the keypad number?
Change the number as soon as you can, and if the model supports individual entries, remove that person's entry specifically. Then review who else knows the number. If you think the person may return without permission, consider rekeying any mechanical lock too, and keep a record of who has what. If you feel threatened, call 911.
Is it safe to install an access system myself?
Simple battery-powered keypad locks are often a manageable project, but anything involving wiring, electric strikes, exit devices or doors that are part of a required exit route should be left to a qualified professional. Mistakes can trap people inside or leave a door unsecured. Do not alter any lock on an exit path without checking local requirements.

Power failures, batteries and what happens when the system goes down
Electronic access systems depend on power, and South Florida sees outages during storms. Before choosing a system, ask what happens when power fails. Some locks are fail-secure, meaning they stay locked, while others are fail-safe, meaning they release. The right choice depends on the door. An exterior security door may prefer to stay locked, while a fire exit must release for safety. Understanding this prevents unpleasant surprises. It is also smart to know where the power shutoff for the access system sits, and who can reach it, so staff do not wander the building during an outage guessing.
Battery-powered keypads and smart locks have their own risks. Batteries run down, often at inconvenient times, and many units give a warning for only a short period. Build a habit of replacing batteries on a schedule, such as at the start of storm season, instead of waiting for the warning light. Keep a spare set where staff can reach them, and know whether your lock has an external contact for emergency power. After a storm, test every keypad and reader, even those that seem fine, since water, surge and heat can damage electronics in ways that only show up later.
Mechanical backup is worth keeping. A key override on an electronic lock gives you a path in when the system fails. Store that key safely and let only a few people hold it. A technician can describe how a particular lock handles power loss and what options exist. Authority to approve changes is confirmed first, and the scope and any quote are explained before work begins. Call us to confirm availability. A tag on the override key that does not say what it opens is a sensible precaution, and keeping a second copy in a sealed envelope at another location is a useful backup.
