Rekeying is the practical way to take back control of who can open your doors. Instead of replacing hardware, we change the internal pin configuration of the lock you already own, so the old keys no longer turn the cylinder and a new key does. It is the usual first step after buying a home, ending a tenancy, parting ways with a roommate or contractor, or losing a set of keys.
Covina is an older, established San Gabriel Valley city, and its housing reflects that. Downtown Covina near Citrus Ave has 1920s and 1930s Craftsman and Spanish bungalows, where original mortise locks and older rim locks are still common. Around them sits post-war tract housing, with ranch-style and larger-lot homes toward Charter Oak and Covina Hills. Each of these calls for a slightly different approach, and a technician who knows the hardware can tell you quickly whether rekeying is the right choice or whether a lock is too worn to be worth it.
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, with no storefront to visit. We bring the tools and key blanks to your door, whenever you need us, day or night.
How it works in Covina
- 1
Call and describe the locks
Call (323) 997-8867 and tell us what you have: how many exterior doors, whether there are deadbolts, knob locks, a garage entry or side gates, and roughly how old the hardware is. This helps us arrive prepared for your property.
- 2
Inspect each lock on site
We check every cylinder before touching it. A lock that works smoothly can be rekeyed. One that is badly worn, damaged, or mismatched may be better replaced, and we will tell you plainly which is which, especially with original hardware on older Covina bungalows.
- 3
Rekey the cylinders
We remove each cylinder, replace the internal pins to match a new key cut, and reassemble it. Where it makes sense, we can set multiple locks to the same key so you carry one key for the front door, back door, and garage entry.
- 4
Test every lock and key
We operate each lock with the new key several times, confirm the bolts extend and retract fully, and verify that the old key no longer works. Doors that stick or misalign are noted so they do not become a lockout later.
- 5
Hand over keys and advise on next steps
You receive the new keys and, if you like, suggestions on weak points such as a short strike plate screw or an aging deadbolt. Upgrades are always optional and discussed before any work is done.

What affects the price
- The number of locks and cylinders being rekeyed, since each one is handled individually.
- The type of hardware, such as standard deadbolts, knob sets, mortise locks, or high-security cylinders.
- Whether you want all locks keyed alike or each kept on a separate key.
- The number of new keys you need cut.
- The condition of the locks, as worn hardware may call for repair or replacement rather than rekeying alone.
- The time of day and location of the visit, since we serve customers around the clock.

Lock Rekeying across Covina
Covina's mix of housing means rekeying needs vary from block to block. In Downtown Covina, around Citrus Ave and Heritage Plaza, Craftsman and Spanish bungalows often still carry original mortise locks, and a deadbolt upgrade sometimes pairs well with a rekey. Small downtown retail and offices near the Covina Center for the Performing Arts also call for rekeying when staff change or a tenant moves out.
A common request comes from buyers in Charter Oak (91724), who want every lock rekeyed right after a purchase closes so previous owners, agents, and contractors no longer hold working keys. Covina Hills, to the south, has larger-lot homes with more doors, side gates, and garage entries, which makes keying them alike especially convenient. We also serve homes and apartments in 91722 and 91723.
Whether you live close to Azusa Ave, Grand Ave, Badillo St, or Arrow Hwy, or commute from the Covina Metrolink station on the San Bernardino Line, we come to you. Call (323) 997-8867 any hour to arrange a visit.
