Copying a key sounds simple until you are holding a worn, third-generation copy that barely turns, or a key stamped with a restriction that the hardware store down the street will not touch. In Covina, where a good share of the housing is older, those situations come up often. A key that has been duplicated from a duplicate drifts a little further from the original cut each time, and eventually it sticks, jams, or breaks off in the lock.

Crenshaw Lock Company is fully mobile. David Shar has run the business since 1987, and we bring the cutting equipment to your home, office or business rather than asking you to drop keys off somewhere. That matters if you only have one working key and cannot afford to hand it over, or if the lock itself needs a look before a copy is worth making.

This page explains how on-location duplication works in Covina, what changes the cost, and what to expect with different kinds of keys, from the old mortise locks in Downtown Covina bungalows to the newer deadbolts in tract homes around Charter Oak and Covina Hills. If you would rather just talk it through, call (323) 997-8867 at any hour.

How it works in Covina

  1. 1

    Tell us what you need copied

    Call (323) 997-8867 and describe the keys: house, office, mailbox, padlock, or a restricted key. Tell us about the lock's age and brand if you know it. We are available 24/7, so you can call whenever it suits you.

  2. 2

    We come to your Covina location

    Because we are fully mobile, the work happens at your door, whether that is a bungalow near Citrus Ave, an apartment off Azusa Ave, or a larger-lot home in Covina Hills. There is no shop to drive to.

  3. 3

    Inspect the original key and the lock

    Before cutting, we check the key for wear and test it in the lock. If the original is badly worn, a copy of it will inherit the problem, so we may recommend cutting from the lock's code or rekeying instead.

  4. 4

    Cut and fit the copies

    We cut the new keys on location and test each one in the actual lock, not just compare it by eye. A copy that looks right but binds in the cylinder gets adjusted or recut.

  5. 5

    Verify restricted and special keys

    Restricted keyways require authorization from the lock's owner or proper documentation. We will explain what is needed and will not copy a restricted key without it.

  6. 6

    Final check and hand-off

    We confirm every key works smoothly, including the deadbolt and any secondary locks, and hand them over so you can try them yourself before we leave.

What affects the price

  • Key type: a basic house key is a different job from a high-security, restricted or dimple key, which need specialized blanks and equipment.
  • Number of copies: more keys cut in one visit generally means less cost per key than separate trips.
  • Condition of the original: a worn or damaged key may need to be duplicated by code or the lock serviced, which adds work.
  • Restricted keyway authorization: restricted systems involve verification steps and sometimes manufacturer-controlled blanks.
  • Lock age and hardware: older mortise or rim locks in historic buildings can need hand fitting, while newer deadbolts are usually quicker.
  • Time of day: because we operate 24/7, after-hours and holiday requests can be priced differently from daytime visits.

Why Covina chooses us

  • Fully mobile: we cut keys at your door, so you never have to give up your only working key or travel anywhere.
  • In business since 1987, with long experience on older hardware like the mortise and rim locks found in Covina's 1920s and 30s buildings.
  • We test copies in your actual lock rather than trusting a visual match, which avoids keys that look right but stick.
  • Honest recommendations: if a worn key or tired lock means a copy will not hold up, we say so and suggest rekeying or repair instead.
  • Available 24/7 at (323) 997-8867, including for office and business keys that cannot wait until the next business day.
  • Careful with restricted keys: we follow proper authorization steps instead of copying anything that walks in.

Key Duplication across Covina

Covina has a lot of variety in its locks. Around historic Downtown Covina, near Citrus Ave, Heritage Plaza and the Covina Center for the Performing Arts, you find 1920s and 30s commercial buildings and Craftsman and Spanish bungalows where original mortise and older rim locks are still common. Keys for those can be worn thin or oddly shaped, and a careful cut and fit makes the difference. Small downtown retailers also often need extra office or storefront keys for staff.

East of downtown, Charter Oak (91724) and the post-war tract streets of 91722 and 91723 are mostly single-family homes, many with deadbolts that have collected a handful of copies over the years. Covina Hills to the south adds ranch-style and larger-lot homes, often with several entry doors, gates and side locks that all need matching keys. A new owner after a closing often asks for extra keys, and sometimes a rekey so that old copies stop working.

We travel the corridors people here already use, including Interstate 10, Azusa Ave, Grand Ave, Badillo St, San Bernardino Rd and Arrow Hwy, and we can meet commuters at home near the Covina Metrolink station on the San Bernardino Line. Whether it is a spare for a teenager, a mailbox key, or office keys for a business, call (323) 997-8867 and we will come to you.

Key Duplication in Covina — FAQs

Can you copy keys at my home in Covina without me leaving?
Yes. We are fully mobile and cut keys on location at your home, apartment or business. There is no storefront to visit. Call (323) 997-8867 to arrange a visit.
Do you offer key duplication at night or on weekends?
Yes, we are available 24/7. Call (323) 997-8867 any time and we will discuss what you need and schedule a visit.
Can you copy a key marked Do Not Duplicate?
That marking alone is not a legal barrier, but we are careful. For truly restricted keyways, we require proper authorization before cutting. We will explain the steps when you call.
My key is very worn. Is a copy worth making?
Often a copy of a worn key inherits its flaws and may stick or break. We may recommend cutting by code or rekeying the lock. We will check the key and lock first.
Can you duplicate keys for the older locks in Downtown Covina bungalows?
Yes. We regularly work with older mortise and rim locks common in 1920s and 30s buildings. Some need hand fitting, and we can talk through options at the door.
Should I rekey instead of copying keys after buying a home in Charter Oak?
If you do not know who holds copies of the old keys, rekeying is usually wise, since it makes old keys useless. We can rekey and cut new keys in one visit.
Can you make mailbox or office keys?
Yes, we cut mailbox, office and building keys on location. For restricted or shared building systems, authorization may be needed. Call (323) 997-8867 with the details.
How is key duplication priced?
Price depends on key type, how many copies, the condition of the original, any restricted keyway steps, lock age and time of day. We explain what applies before starting work.
