You have just moved into a home, a tenant has returned the keys, or one key has gone missing. The first question is usually simple: how long does lock rekeying take? For most standard residential locks, an experienced locksmith can rekey a single lock in about 10 to 20 minutes. A whole house with several exterior doors often takes around 30 minutes to an hour.
The exact time depends on the type and condition of the locks, how many locks need service, and whether they can all be set to work with one new key. Rekeying is usually much faster and less expensive than replacing good hardware, especially when the goal is to prevent an old key from working.
How Long Does Lock Rekeying Take for Most Homes?
A straightforward rekeying job is not an all-day project. If your deadbolt and doorknob are standard residential locks, in good working condition, and accessible, the work moves quickly. The locksmith removes the cylinder, changes the small internal pins to match a new key, tests the lock, and makes sure the key operates smoothly.
For one exterior door with a deadbolt and keyed knob, plan on roughly 20 to 30 minutes. For two or three doors, many jobs are finished within an hour. That includes checking the locks and cutting enough new keys for the household.
A locksmith can often rekey several compatible locks to one key. That is convenient when you are tired of carrying separate keys for the front door, back door, side gate, garage entry, or office. It can add a little setup time, but it saves frustration every day afterward.
What Can Make Rekeying Take Longer?
The biggest factor is the lock itself. Older locks, damaged cylinders, high-security hardware, and locks that have been painted over or badly worn may need extra attention. A lock that sticks, turns roughly, or has a broken key inside it should be repaired before it is rekeyed.
Here are the situations that commonly extend the appointment:
- Several doors or locks: A larger home, rental property, or business with many entry points naturally takes longer than one front door.
- Different keyways and brands: Not every lock can be keyed alike. Some brands or keyways are incompatible, so separate keys may be needed unless hardware is changed.
- Worn or damaged hardware: A locksmith may find a loose deadbolt, a failing latch, stripped screws, or a cylinder that is nearing the end of its service life.
- High-security or restricted key systems: These locks may require special parts, authorized keys, or more detailed work.
- Missing keys and unknown lock history: Rekeying can still be done without an existing key, but disassembling and servicing the cylinder may take longer.
These issues do not always mean you need a replacement. In many cases, a skilled locksmith can repair the problem and rekey the lock during the same visit. But if a lock is badly corroded, damaged from a break-in attempt, or no longer reliable, replacing it is the better call.
Rekeying Without the Old Key
Customers often assume they need to hand over an old working key before a lock can be rekeyed. That is not always true. A locksmith can usually rekey a lock even when the old key is lost, stolen, or left with a former tenant.
It may take a little more time because the cylinder must be accessed and decoded without using the existing key. Still, this is a common service call. If security is the concern, do not wait to locate a missing key before getting the lock changed.
Rekeying vs. Replacing a Lock
Rekeying changes who can use the lock. Replacing changes the lock hardware itself. If your locks are solid, operate properly, and meet your security needs, rekeying is often the practical choice.
Rekeying makes sense after buying a home, ending a lease, changing staff access, losing keys, or giving out too many spare keys over the years. It gives you control over access without throwing away hardware that still works.
Replacement is worth considering when the lock is damaged, outdated, difficult to operate, or does not provide the level of security you want. It can also make sense if you want to upgrade from basic hardware to a stronger deadbolt, a keypad lock, or a commercial-grade setup.
A good locksmith should not push replacement when rekeying will solve the problem. On the other hand, rekeying a lock that is already failing can leave you with the same reliability issue. The right answer comes down to the condition of the hardware and what you need it to do.
What to Expect During a Rekey Appointment
A professional rekey appointment should be simple and straightforward. The locksmith will first look at each lock, identify the brand and keyway, and confirm which doors you want changed. If you want all locks to use one key, this is the time to mention it.
Next, the locksmith removes and services the cylinders, installs the new pin combination, and cuts new keys. Each lock should be tested several times from both sides of the door. The key should turn smoothly, the deadbolt should fully extend into the strike plate, and the door should latch without forcing it.
For a home, it helps to decide ahead of time which doors need attention. Do not forget the garage-to-house door, side gates, storage rooms, sheds, or a back entry that is rarely used. An old key that works on one forgotten door can defeat the purpose of rekeying the main entrances.
If you manage a rental or small business, make a quick list of doors and keyholders before the locksmith arrives. That helps avoid missed access points and makes it easier to decide whether employees, maintenance staff, vendors, or former occupants should still have access.
Can Locks Be Rekeyed in an Emergency?
Yes. Rekeying is often requested after a lost key, theft, eviction, break-in, or relationship change. In those cases, speed matters, but the work should still be done carefully. A rushed job that leaves a lock sticking or a door unsecured is not a solution.
Mobile locksmith service is especially useful because the work can be completed at your location. Joe’s Lock and Key serves Bakersfield and nearby communities with practical on-site help for homes, businesses, and vehicles. Whether the concern is one missing key or several doors at a property, the goal is to restore control of access without creating more hassle.
If there has been forced entry or visible damage, ask the locksmith to inspect more than the key cylinder. The strike plate, door frame, latch, and deadbolt can all be affected. Rekeying stops the old key from working, but it does not repair hardware that has been compromised.
A Few Ways to Keep the Job Moving
You do not need to prepare much for lock rekeying, but a few details can save time. Make sure the locksmith can access every door you want serviced, including a side yard or detached garage. Keep pets safely inside or away from the work area, and have a decision ready about how many keys you need.
If you have keys that you want matched, bring them out before the appointment starts. If you are unsure whether every lock should use the same key, the locksmith can explain what is compatible and what makes the most sense for your property.
Rekeying is one of the quickest ways to get peace of mind after your keys have changed hands. When the locks are in good condition, it is usually a short visit with a lasting result: the people you trust have working keys, and the old ones no longer do.
