Rekeying changes the inside of a lock so that a new key operates it and every previous key becomes useless. The hardware stays on your door. Only the pin configuration changes. For a home you have just bought, a tenant who moved out, or a set of keys that went missing years ago, it is usually the most sensible way to restore control over who can enter, without paying to replace good hardware.

In La Cañada Flintridge this matters more than it might elsewhere. Many homes here are large mid-century ranches from the 1950s through the 1970s, and a single property can have a front door, a back slider, a side gate, a garage entry, a pool or guest house, and a pedestrian gate at the street. Over decades, keys for all of those get copied, handed to contractors, housekeepers, neighbors and previous owners. Rekeying lets you pull all of that back to one key you control.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so there is no shop to drive to. We bring the tools and key stock to your property, work on site, and test every lock before we leave. We are available around the clock, which helps when you want a rekey done the same day you get the keys to a new house.

How it works in La Cañada Flintridge

  1. 1

    Tell us what needs rekeying

    Call (323) 997-8867 and describe the property: how many entry doors, whether there are gates, a garage door entry, a mailbox or outbuildings, and what brand of locks you have if you know it. This lets us plan the visit and bring the right parts.

  2. 2

    We come to you

    We are fully mobile and available 24/7, so we meet you at the house, whether it is a hillside property in Flintridge or a ranch home off Foothill Boulevard. There is no storefront, and the work happens at your door.

  3. 3

    Inspect each lock

    Before taking anything apart, we check that every lock is in good working order. Rekeying only makes sense on hardware that is sound. If a deadbolt is worn, loose or an outdated grade, we will tell you honestly and explain your options.

  4. 4

    Rekey to a single key

    We remove the cylinders, replace the internal pins to match a new key, and reassemble. Where the brands allow, we match the front door, side gate, garage entry and other locks to one key so you carry just one.

  5. 5

    Test and cut spare keys

    We test each new key repeatedly in every lock, and confirm that the old key no longer works. We then provide extra keys as needed so family members or trusted people have what they need.

  6. 6

    Review upgrade options

    If you want more security, such as a high-security deadbolt, restricted keyways or a smart lock, we can talk it through. It is optional, and you decide whether to rekey only or upgrade.

What affects the price

  • The number of locks and cylinders to be rekeyed, since each one is handled individually.
  • The brand and type of hardware, because some locks and gate locks are simpler to rekey than others.
  • Whether you want everything keyed alike to one key, or separate keys for certain doors.
  • How many copies of the new key you need, and whether they are restricted or high-security blanks.
  • Whether any lock is worn or damaged and needs to be replaced instead of rekeyed.
  • The time of day and location of the visit, since we operate 24/7 and some requests are urgent or after hours.

Why La Cañada Flintridge chooses us

  • Fully mobile service. We come to your property rather than asking you to drop locks off anywhere.
  • In business since 1987, with owner and lead tech David Shar involved in the work.
  • Experience with multi-entry properties, including perimeter gates, pedestrian gates, garage doors and side doors, not just a single front door.
  • Honest recommendations. If a lock is better rekeyed, we say so, and if it is truly worn out, we say that too.
  • Available 24/7, which is handy for new homeowners who want locks changed the moment they get the keys.
  • Option to pair rekeying with high-security deadbolts or smart-lock setups for owners who prefer them.

Lock Rekeying across La Cañada Flintridge

La Cañada Flintridge is split by the 210 Freeway, and its housing changes as you move from the flats to the slopes. Near Foothill Boulevard and the older parts of 91011, we often see well-kept mid-century ranch homes where a new owner, perhaps a JPL engineer who just bought nearby, wants the house, side gate and garage all on one key. Rekeying is a practical fit: the existing hardware stays, and the previous owner's keys stop working.

Up in Flintridge and Alta Canyada, and around the Sagebrush area, properties tend to be larger, with long driveways, perimeter gates and pedestrian gates. A gated hillside estate off Alta Canyada may have several gate locks plus multiple house doors, and rekeying them together can simplify daily life. Many owners here also like high-security deadbolts or smart-lock packages, and we can add those during the same visit. ZIP code 91012 and 91011 both include properties like these.

We also work around the area's gathering places. If you are visiting Descanso Gardens or Memorial Park and have a car lockout or key-fob problem, call (323) 997-8867 and we will help. Whether you live near Flintridge Preparatory School, off Verdugo Boulevard, or toward Angeles Crest Highway, our mobile service reaches you day or night.

Lock Rekeying in La Cañada Flintridge — FAQs

What is the difference between rekeying and changing locks?
Rekeying alters the pins inside your existing lock so a new key works and old keys do not. Changing locks replaces the hardware itself. Rekeying is usually the more economical choice when your locks are in good shape. Call (323) 997-8867 and we can advise on which fits.
Should I rekey after buying a home in La Cañada Flintridge?
Yes, it is a smart first step. You cannot know who has copies of the old keys, including past owners, agents, contractors and housekeepers. Rekeying makes sure only the keys you hold will work.
Can you rekey all my locks to the same key?
In most cases yes, when the locks are compatible brands and keyways. We can often put the front door, side gate, garage entry and other locks on a single key. We confirm what is possible when we inspect them.
Can you rekey gates and pedestrian gates?
Yes. Many properties here have perimeter or pedestrian gates in addition to house doors. We rekey compatible gate locks and can include them with the rest of the property so everything works from one key.
Do I need to be home during the rekey?
Someone authorized should be present so we can get access and hand over the new keys. For a new home, many owners meet us right after closing. Call (323) 997-8867 to arrange the visit.
Will my old keys still work afterward?
No. After rekeying, the old keys no longer turn the lock. We test this on each lock before we leave.
When is replacing a lock better than rekeying?
If the lock is worn, damaged, loose, or does not offer the security level you want, replacement is the better choice. Some owners also upgrade to high-security deadbolts or smart locks. We will give you a straight recommendation.
Do you offer service at night or on weekends?
We are available 24/7 and fully mobile. We do not have a storefront, since we come to you. To schedule rekeying or ask a question, call (323) 997-8867.
