Your door belongs to more than one party
In a house, the front door is yours to change as you please. In a condo or high-rise, the answer is less simple. The unit entry door often sits on the boundary between your private space and a common corridor, and many associations treat the door, the frame or the outside face of the hardware as common property or as something that must follow a building standard. The inside of the lock may be yours, but the door itself may not be.
This is why the first step in any lock project in a multi-unit building is to read your governing documents or ask your property manager. Typical questions are whether the association must approve a new lock, whether there is a required brand or finish, whether the management holds a master or emergency key, and who pays for what. Skipping this step can lead to an order to reverse the work.
None of this is meant to discourage you from improving your security. It is simply the correct order of operations. Once you know the rules, a locksmith can work comfortably inside them, and the result will be something the building accepts and the first responders can still open if they ever need to.
Fire-rated doors and why they matter
Unit entry doors in many multi-story buildings are fire-rated. That means the door, its frame, its hinges and its hardware have been designed to work together to slow the spread of fire between the unit and the corridor. A fire-rated door is usually heavy and is often fitted with a self-closing device so that it shuts and latches on its own.
Because the rating depends on the whole assembly, certain changes can undo it. Drilling large new holes, removing the closer, wedging the door open or replacing the latch with something that does not engage reliably can all reduce its protective value. A locksmith who works in multi-unit buildings knows to keep the door's function intact and to choose hardware that suits a rated door.
For you as an owner, the practical rule is simple: do not modify the door's structure or its closing hardware without advice. If your door no longer latches by itself, tell the property manager. A door that has to be pulled shut by hand is a safety issue, not only a security one, and it should be corrected promptly by someone who understands the assembly.
Lobby doors, fobs and elevator access
Most towers use electronic access at the lobby, the garage, the pool and sometimes the elevators. Residents carry a fob, a card or a phone credential. When that credential is lost, the usual route is through the association or building management, which can deactivate the old one and issue a new one. A locksmith generally does not handle the building's access system, which belongs to the association and its vendor.
Where a locksmith helps is at your own unit. If you are locked out of your door while you hold a perfectly good fob, that is a lock problem, not an access system problem. Likewise, a broken key in the unit deadbolt or a lever that no longer latches is a locksmith job. Knowing which party to call first saves a lot of time and frustration.
If you rent your unit to others, keep track of fobs as carefully as keys. A tenant who moves out with a fob can still enter the lobby until it is deactivated. Contact the management office at move-out so the old credential is cancelled, and consider a rekey of the unit door at the same time.
Association rules on keyways and master keys
Some buildings run a master key system or a restricted keyway so that the association, and sometimes emergency services, can open any unit in an emergency. If your building does this, you may not be allowed to switch to a different keyway or to install a lock that management cannot open. That is not an unreasonable rule when a burst pipe or a medical emergency requires entry to an empty unit.
A locksmith can often work within that rule by rekeying your existing cylinders or by installing a new lock that matches the building's required keyway. Do not assume you may choose any brand. Ask the management what is required and, if possible, get the requirement in writing so that the technician can match it.
If you are considering a smart lock, ask the association first. Some buildings allow them with conditions, such as a backup key cylinder that fits the building's system. Others do not. Our smart lock buying guide lists what to check on the product side, while the association can tell you what its rules allow.
Lockouts in a tower: what is different
A lockout in a high-rise has a few quirks. The corridor is shared, so noise and time matter. A hallway camera may record the visit. Building management may need to know. Some towers ask that a locksmith check in with the front desk and show identification, which is a good practice that protects every resident.
You will usually be asked to prove that the unit is yours, with identification that matches the unit or with a lease and the property manager's confirmation. This is not an obstacle but a protection. A locksmith who opens any door for anyone who asks is a risk to everyone in the building.
If you are locked out and a child, an elderly person or a pet is inside, say so right away, and if anyone's safety is at risk, call 911 first. Emergency responders have their own means of entry. For ordinary lockouts, call, describe the door and the building, and hear the service call charge and the quote before dispatch. Our house lockout page explains the general process.
Balcony doors and sliding glass
Many condos have a balcony or patio reached through a sliding glass door. On upper floors the risk of entry from outside is lower, but ground-floor and second-floor units are a different matter, as are units with shared balconies or adjacent roofs. A sliding door with a weak latch can often be lifted out of its track or forced with modest effort.
A simple and sensible measure is a bar or pin in the track so that the door cannot slide open even if the latch is defeated, together with a working secondary lock. Our sliding glass door guide goes through the options. Check your association rules about changes to balcony doors, because the glass and frame may be common property.
On any floor, a balcony door left unlocked is an open invitation, and a door that has been left unlocked by habit is a common cause of insurance questions. Make a habit of checking the balcony door as part of your leaving routine.
Buying or moving into a condo
When you buy a unit, you inherit a history of keys. Previous owners, tenants, cleaners, agents and contractors may have held copies, and there may be keys in a lockbox or with the management office. The sensible first step after closing is to rekey the unit door and any other locks that matter, such as a storage cage or a mailbox, subject to association rules.
Ask the management office for a list of what they hold, what they do not, and whether the building keeps a key on file for your unit. If the association holds a key for emergencies, find out how it is stored and who can access it. Understand what happens if you change the lock and whether you must provide a new key to the office.
Take the opportunity to check the door, too. Does it close and latch on its own, is the weatherstripping intact, and does the deadbolt throw fully? A small adjustment now is easier than a lockout later. Our moving-in security steps cover more of the checklist.
Owners who rent their unit
Landlords in multi-unit buildings face a repeated question: what happens to the keys between tenants? The best practice is to rekey the unit at every turnover, so that no previous tenant retains access. It is quick, it is usually modest in scope compared to replacing hardware, and it removes a lot of doubt.
Short-term rental owners have a different need. Guests come and go and keys can be lost or not returned. A keypad lock that allows changing the entry number between guests can help, provided the association permits it. Where it does not, a lockbox arrangement may be the answer, again subject to building rules, because some buildings ban lockboxes in common areas.
Whichever method you choose, keep records: who has a key, when the lock was last changed and what the association has been told. If you use a property manager, make sure they follow the same process. Our property manager service page describes how we work with managers across several units.
Common mistakes in multi-unit buildings
The first mistake is buying hardware online and installing it before asking the association. A lock that does not match the required finish or keyway can be ordered removed, and the cost of doing the work twice is entirely avoidable. Ask first, then buy or have a locksmith supply the right product.
The second is treating a lost fob as a lost key. They are separate systems with separate owners. Calling a locksmith about a lobby fob wastes a visit, while calling the front office about a broken key in your unit deadbolt does the same. Sort the problem into building access or unit lock before you pick up the phone.
The third is leaving the door in a condition that no longer latches on its own. Weatherstripping that drags, a closer that has been disconnected because it was noisy, or a latch that sticks can all lead to a door resting slightly ajar. In a corridor, that is both a security and a safety problem. A quiet fix by someone who understands rated doors is better than a workaround.
The fourth is sharing a key casually. Cleaners, dog walkers, relatives and friends may all have a copy by the end of a year. Keep a written list and rekey when the list gets long or the people on it are no longer part of your life. In a building where neighbors are a few steps away, a calm routine of key control is the simplest form of protection.
Things to check before you call
A little preparation makes a locksmith visit smoother and the phone quote more accurate. Gather the unit number, the building name and the address of the main entrance. Know whether there is a front desk or a gate and how a visitor gets in. Have your identification and your proof of residence ready.
Think about what you want to achieve. A rekey, a new deadbolt, a smart lock, a repair of a stuck lever or a replacement of a worn cylinder are different jobs with different parts. If you have documents from the association about hardware, have them handy. If the building has a required keyway or brand, say so on the call.
Remember that quotes are given by phone only, and complicated jobs, such as hardware on a rated door that needs adjustment, may need an on-site look first. A service call charge applies and is explained before dispatch. When you are ready, call and tell us about your building.
- Unit number, building name and entrance instructions
- Identification and proof that the unit is yours
- Association rules or approval about hardware, if any
- The type of work you want and any problems you have noticed
- Whether a child, an elderly person or a pet is inside the unit
Keeping a tower unit secure day to day
Security in a building is partly about hardware and partly about habits. Do not hold the lobby door for people you do not know, do not prop a unit door open while you carry things in, and report a door that no longer latches. If a neighbor has lost a fob or a key, an alert to management helps everyone.
Keep your own key and fob count under control. Write down how many exist and where. Avoid leaving a spare with a person you do not fully trust, and avoid hiding one in the corridor, where cameras and neighbors are not a substitute for a lock. If you must share access with a cleaner or a family member, consider rekeying when the arrangement ends.
A good lock on a good door in a building that follows its own rules is a strong combination. If something feels off, such as a deadbolt that sticks or a latch that does not catch, have it looked at before it fails. Call and describe what you notice, and a technician will help you decide what is worth fixing.
Questions people ask
Can I change the lock on my condo front door?
Often yes, but the door may be common property or the association may require a specific brand, keyway or approval. Check your governing documents or ask management first. Once you know the rules, a locksmith can rekey or replace hardware that fits them. Call and describe your building so the technician can plan the work.
Why should I not modify a fire-rated unit door?
The door, frame, hinges and hardware work together as a rated assembly. Large new holes, a removed closer or hardware that does not latch reliably can reduce its protection. Ask a locksmith who understands rated doors, and tell management if your door no longer closes and latches on its own.
Does a locksmith handle lobby fobs and building access?
Generally no. Lobby, garage and elevator access belongs to the association and its vendor, so a lost fob is a matter for building management. A locksmith helps with your own unit lock, such as a broken key, a stuck deadbolt, a lever that will not latch or a rekey.
What proof will I need if I am locked out of my unit?
Expect to show identification that matches the unit, or a lease plus confirmation from the property manager. This protects every resident from someone opening doors for strangers. Some buildings also ask a visiting technician to check in at the front desk. Mention anyone inside who might be at risk when you call.
Should I rekey after buying a condo?
It is a sensible step. Previous owners, tenants, agents and contractors may have held copies of the keys. Rekeying makes the old keys useless. Check association rules about the keyway and whether management holds a key, then call and describe your door so a quote can be given by phone.
Can I install a smart lock in a high-rise unit?
Possibly, but ask the association first because some buildings allow them only with conditions, such as a backup key cylinder in the building's keyway. Others do not allow them. A locksmith can advise on products that fit a rated door. Quotes come by phone, and complicated jobs need an on-site visit.
Describe the situation by phone and we will tell you what the job involves. Quotes are given by phone. Jobs that cannot be quoted without seeing them need a technician on site, and the service call charge is explained on the phone before anyone is dispatched.
