Rekeying is the quiet fix that makes a move or a sale feel safe. Instead of replacing hardware, we change the internal pin configuration of the cylinder so a new key works and every previous key does not. The locks you already like stay on the door, and the people who held the old keys lose their access. In a city like Signal Hill, where homeowners often inherit locks from several previous owners, contractors, and tenants, that matters.

Signal Hill is a compact hilltop city completely surrounded by Long Beach, and its housing varies a lot from block to block. There are older homes, a big wave of 1990s and 2000s hillside townhomes and view condos built on redeveloped oil land, and commercial and industrial parcels, including the Cherry Avenue auto corridor. Each of these has different rekeying needs, from a single front-door deadbolt to a whole set of gate padlocks that should all open with one key.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no storefront to visit. We bring the tools and key-cutting equipment to you, which is handy when you are in the middle of unpacking boxes or standing at a property you just closed on.

How it works in Signal Hill

  1. 1

    Tell us about the locks

    Call (323) 997-8867 and describe what you have: how many doors, whether they are deadbolts, knob sets, mailbox locks, or gate padlocks, and the brand if you know it. Mention whether any are smart locks or keypads, since those are handled differently. This helps us arrive with the right parts.

  2. 2

    We come to you

    We are available 24/7 and fully mobile, so we drive to your Signal Hill address, whether that is a hillside townhome, a house near Discovery Well Park, or a commercial lot off Cherry Avenue. Because we work from a vehicle, there is no shop visit or drop-off.

  3. 3

    Inspect each cylinder

    Before rekeying, we check that each lock is in working condition. Worn or corroded cylinders, common on exterior hardware and oil-field gates, may need cleaning or freeing up first. If a lock is too damaged to rekey reliably, we will tell you and explain the options.

  4. 4

    Rekey to a new key

    We remove each cylinder, replace the pins to match a new key cut, and reassemble it. We can key multiple locks alike so a single key operates your front door, back door, and garage entry, which is convenient for households and small businesses.

  5. 5

    Test and hand over keys

    We test every lock with the new key and confirm that the old key no longer turns it. You receive the new keys and we can cut extra copies. Anything left unresolved, such as a smart-lock setting, we walk you through before we leave.

What affects the price

  • The number of cylinders being rekeyed, since each lock takes its own labor and pinning.
  • The type of lock: standard deadbolts and knob sets differ from high-security cylinders, mailbox locks, or commercial padlocks.
  • Whether locks are in good condition or corroded and seized, which is common at oil-field and industrial gates and takes extra effort to free up.
  • Whether you want all locks keyed alike, and how many extra key copies you need.
  • The time of day and the urgency of the visit, since we serve 24/7 including nights, weekends, and holidays.
  • Any additional work found during inspection, such as a broken cylinder or smart-lock reprogramming that goes beyond a straightforward rekey.

Why Signal Hill chooses us

  • Fully mobile service. We bring the equipment to your door in Signal Hill, with no storefront and no need to carry locks anywhere.
  • In business since 1987, with owner David Shar leading the work, so you are dealing with long experience rather than a rotating call center.
  • Comfortable with Signal Hill's mix of property types, from older homes to hillside townhomes to industrial parcels and dealership lots.
  • We tell you plainly when rekeying makes sense and when a lock is better replaced, rather than pushing the bigger job.
  • Available 24/7, which suits move-in days, late closings, and security concerns that cannot wait until morning.

Lock Rekeying across Signal Hill

Signal Hill sits on a hill in the middle of Long Beach, and its streets reflect that history. Around the Hilltop area near Hilltop Park, many homes and condos have views and share access systems with HOAs, and a lot of owners have never rekeyed locks that were installed when the buildings went up in the 1990s and 2000s. Moving in is a natural time to change them, and we handle that kind of job at addresses in ZIP code 90755 regularly.

Down in the Discovery Well district, near Discovery Well Park where oil was found in 1921, you will find older housing next to active oil-pumping parcels. The Panorama Promenade links that area with Hilltop Park, and the properties around it range from small residences to industrial lots. Perimeter gates and padlocks on working oil sites get exposed to weather and grime, so corroded cylinders are a real issue. We can rekey them, free up stuck ones, and set them so authorized staff share a key.

Along the Cherry Avenue auto corridor and the Signal Hill Auto Center, businesses deal with keys of a different kind: shop doors, lot gates, offices, and the occasional lost vehicle key or fob. Whether you are off Spring Street, Willow Street, California Avenue, or just off the I-405, call (323) 997-8867 and we will come to you.

Lock Rekeying in Signal Hill — FAQs

What is the difference between rekeying and changing locks?
Rekeying changes the internal pins of your existing cylinder so a new key works and old keys do not. Changing locks replaces the hardware itself. Rekeying is usually the simpler option when your locks are in good shape. Call (323) 997-8867 if you are not sure which fits.
Should I rekey after buying a home in Signal Hill?
Yes, it is a smart step. You cannot know who still has keys from previous owners, tenants, or contractors. Rekeying makes sure only the keys you hold will work, and it is especially useful in hillside townhomes and condos where you may inherit several locks.
Can you rekey locks that are corroded or stuck?
Often, yes. Exterior locks and oil-field gate padlocks can seize up from weather and residue. We inspect them first, free them up where possible, and rekey them. If a cylinder is too damaged, we will explain whether replacing it makes more sense.
Can all my locks work with one key?
In most cases, yes. We can key your front door, back door, and other compatible locks alike so one key opens them all. Mixed brands can sometimes limit this, which we check during inspection.
Do you rekey smart locks and keypad locks?
Mechanical cylinders in those locks can often be rekeyed, but keypad codes and smart features are reprogrammed instead. Many newer Signal Hill townhomes and condos have these systems. Call (323) 997-8867 with the model and we will tell you what to expect.
Do you work with businesses on Cherry Avenue?
Yes. We can rekey shop doors, offices, and gate locks, and we can discuss lost-key or fob needs for vehicles. Describe the situation when you call and we will let you know how we can help.
Do I need to visit your shop?
No. Crenshaw Lock Company is fully mobile and has no storefront. We come to your Signal Hill address with the tools needed to rekey on site.
Are you available at night or on weekends?
Yes, we are available 24/7, including nights, weekends, and holidays. Call (323) 997-8867 any time to arrange rekeying.
