Business locks are different from residential locks in one important way: more people have access. Employees, vendors, cleaning crews, contractors. As that population changes, the locks need to reflect who currently has authorized access.
This post is a practical guide for when a Dallas business should rekey, how to do it efficiently, and what to expect from the process.
When rekey makes sense for a business
Employee turnover with key access. If an employee who held a key has left, those keys should be considered out of your control. People intend to return keys; they often don’t. Even when keys are returned, you don’t know if copies exist. Rekey the affected doors.
Termination of a key-holding employee. Especially if the termination was contentious. Don’t wait. Rekey the same day or the next business day.
Departure of a key-holding contractor. Long-term contractors, cleaning services, or service vendors sometimes retain keys. When the relationship ends, rekey.
Security incident. Break-in attempt, missing keys, signs of attempted entry, theft of property where keys may have been compromised. Rekey immediately.
Property change. New tenant in a leased space, new ownership, or new business operating in the building. Rekey as part of the move-in.
Annual or periodic rotation. Some businesses rotate keys annually as a routine practice — particularly businesses handling money, sensitive data, or controlled inventory. This isn’t necessary for every business but is reasonable for some.
Lost or unaccounted-for keys. If someone reports a lost key, treat the affected doors as compromised.
After issuing too many keys. If you’ve lost track of how many keys exist and who has them — common in older businesses — rekey and start over with a documented system.
What “rekey” looks like for a business
The technician arrives with the right pinning kits and key blanks. For each cylinder you want rekeyed:
- Remove the cylinder from the lock.
- Take out the existing pins.
- Install new pins in a different configuration.
- Cut a new key (or several) to match the new configuration.
- Reinstall the cylinder and test.
The old keys stop working immediately. The new keys are clearly labeled and handed to you.
For a small office (5-10 doors), this typically takes 2-4 hours of on-site work. Larger offices scale up linearly.
Master-key systems for businesses
A common request: “Can we have one master key for managers that opens all the doors, and individual keys for each employee that only open their work area?”
Yes. That’s a master-key system. It’s planned and built once, and then maintained as employees come and go.
A typical small business master-key system might have:
- Grand-master (or owner) key: opens everything.
- Department or manager keys: open all doors within a department.
- Employee keys: open only the doors that employee needs (their office, the break room, restrooms).
- Public-area keys: for visitors who need limited access (e.g. a tenant in a shared building).
Each tier is built into the pinning during the initial setup. When an employee leaves, only their level of key needs to change — you don’t have to rekey the whole building.
The trade-off: master-key systems are more complex to design and more expensive to set up. They pay off over time for businesses with frequent turnover.
Scheduling business rekey work
Most Dallas businesses prefer rekey work to happen outside business hours, so the office can continue operating during the day. We routinely schedule:
- Evenings (after 6 PM).
- Weekends.
- Early mornings (before 8 AM).
Larger jobs sometimes split across multiple evenings, hitting different sections of the building each visit. The whole building stays operational throughout the work.
For emergency rekey (after a termination or security incident), we can usually respond the same day even on short notice. Tell us when you call.
What you should give the locksmith
Before the rekey:
- Door count and lock brand if known. This affects the pinning kits we bring.
- Which doors need rekey. Not always the whole building.
- Whether you want all locks keyed alike, or with separate keys.
- Whether you want a master-key system or just simple rekey.
- Any compliance requirements (e.g. high-security cylinders for insurance).
- Operational constraints — what time we can work, which doors are highest-priority.
With those inputs, we can quote and schedule.
Documenting the new system
After any business rekey, you should have:
- Clearly labeled new keys — at minimum, which door each key opens.
- A written record of how many keys exist and who has each one.
- For master-key systems: a written master-key plan showing which keys open which doors.
- A secure place to store the master record (your safe, not on a desk).
If your previous locksmith didn’t leave you with documentation, ask. Without records, the next rekey is harder than it needs to be.
Common mistakes Dallas businesses make
Waiting too long after termination. “We’ll rekey next month” turns into “we’ll rekey next quarter” turns into never. Then there’s an incident.
Issuing keys with no record. Every key out the door should be logged — who got it, when, and the expectation for return.
Trusting that returned keys are the only copies. They aren’t always. Treat any departed employee’s key access as potentially compromised regardless of whether they returned a key.
Rekeying everything when only some doors need it. Most rekey jobs only need to hit a few cylinders, not the whole building.
Buying new locks when rekey would suffice. New locks aren’t more secure than rekeyed ones (same hardware grade). Save the money for hardware upgrades you actually need.
Ignoring the master-key plan when it gets messy. As businesses grow, the original master-key plan often gets ignored — keys are issued ad-hoc, locks get changed by maintenance, and nobody knows what opens what. Periodically auditing and resetting the plan is worth the cost.
What about smart locks for businesses?
Smart locks are increasingly relevant for small businesses. They offer:
- Code-based access that can be revoked instantly when an employee leaves.
- Audit logs showing who entered when.
- No physical keys to lose track of.
- Time-based access (e.g. cleaners can only enter between 6-8 PM).
For some businesses, smart locks dramatically simplify access management. For others (high-security, regulatory compliance), traditional keyed access is still the right answer.
Most Dallas small businesses we work with use a hybrid: smart locks on the main entry, traditional locks on internal sensitive doors.
How we approach business rekey
When you call us, we:
- Talk through the situation on the phone — door count, lock types, urgency, master-key needs.
- Quote a price range and schedule.
- Arrive with the right hardware and pinning kits.
- Do the work within your operational constraints.
- Label all keys and provide written documentation.
- Test every door before leaving.
We also keep your information confidential. Many businesses we work with prefer that we don’t discuss their specific access plans with anyone outside the business. That’s standard.
Bottom line
For most Dallas businesses, rekey is the right answer most of the time — and it’s an event-driven decision, not a calendar-driven one. Anytime your trusted access list changes meaningfully (employee leaves, contractor relationship ends, security incident), rekey the affected doors.
If you want to talk through your specific situation, call us at (972) 962-9955. We do business rekey work across Dallas, scheduled around your hours, with proper documentation.
