Rekeying is the lock job we handle most in Altadena, and for good reason: much of the housing stock here dates from 1900 to 1950, so we’re often working with original mortise locksets and solid wood doors rather than modern pre-drilled slabs. Altadena’s dry heat and Santa Ana winds cause wooden doors to shift seasonally, which means locks that worked fine in February can bind or misalign by August. If you need a locksmith in Altadena who understands century-old hardware, call Greystone Locksmith at (866) 497-9415.
Why Altadena Homes Are Different
Altadena sits at the base of the San Gabriel Mountains, and the housing reflects its history as a foothill community that grew in distinct waves. The ZIP codes we serve, 91001 and 91003, are dominated by detached single-family homes, many of them Craftsman bungalows with original mortise locksets, skeleton-key hardware, and solid wood doors that have been opening and closing for a century or more. This is not like working in a newer Pasadena condo building where every door is pre-drilled for a standard cylindrical lock. In Altadena, a rekey or hardware replacement often means careful retrofit work: preserving the original escutcheon plate, re-boring a door without splintering the millwork, or sourcing vintage parts rather than reaching for a modern cylinder that doesn’t fit the existing prep.
The climate compounds this. Hot, dry summers and occasional Santa Ana winds cause wooden doors and frames to warp, which throws latch alignment off and makes locks stick. We see seasonal call patterns for exactly this reason: a homeowner notices the deadbolt feels stiff in June, and by September the door won’t latch at all. The wildland-urban interface adds another layer. After the 2025 Eaton Fire, we handled a significant volume of rekey and temporary-security work across 91001 as residents returned to damaged or evacuated homes and needed to re-establish control over who had keys.
Styles & brands we work with







Our Main Altadena Services
Two services account for most of the calls we take from Altadena homeowners and drivers. Here’s what each involves locally, and where to read the full breakdown.
Car Key Replacement in Altadena
Losing a car key or having one break off in the ignition is different here than in a denser part of Los Angeles. Altadena’s hillside streets and long driveways mean you can’t always walk to a dealership or wait for a tow. We handle automotive key replacement in the field, cutting and programming transponder keys, fobs, and high-security keys on-site. See Car Key Replacement in Altadena for the full scope, including what we need from you when you call.

Emergency Locksmith in Altadena
Lockouts happen at the worst moments: late at night, with groceries in the trunk, or after returning from an evacuation order. Altadena’s spread-out residential layout means our response needs to be coordinated, not casual. We run emergency calls for lockouts, broken keys, and failed hardware, and we arrive prepared for the specific lock on your door, not just whatever happens to be on the truck. Read Emergency Locksmith in Altadena for response expectations and what counts as urgent.

Rekey Locks in Altadena
Rekeying is the smarter move for many Altadena homeowners, because the existing hardware is often worth keeping. A 1920s Craftsman bungalow with original brass mortise locks doesn’t need a new lock; it needs the pins inside that lock changed so the old keys stop working. That’s what a Rekey Locks service does, and it’s usually a fraction of the cost of replacing the whole set. In a neighborhood where doors and locks have been together for decades, rekeying preserves the integrity of the original installation while giving you total key control.
Lock Rekey
Signs you need it
You’ve moved into a home in 91001 or 91003 and you don’t know who else has a key, or you’ve had a falling out with a roommate, tenant, or contractor.
What it costs in Altadena
A standard lock rekey in Altadena typically runs $85 – $125 for the service call and first lock, with each additional cylinder rekeyed at $20 – $35 per lock.
How we do it
We remove the cylinder, swap the pins to match a new key, and reassemble the lock in place, testing the deadbolt and latch for smooth operation before we leave.
Rekey Door Lock
Signs you need it
A specific door no longer operates with the key you want to use, or you’re consolidating multiple doors to one key and need each cylinder re-pinned to match.
What it costs in Altadena
Rekeying a single door lock in Altadena falls within $85 – $125 for the visit and first cylinder, with additional door locks on the same visit at $20 – $35 each.
How we do it
We re-pin the cylinder to the new key, lubricate the internal springs, and align the strike plate if the door has settled, which is common with Altadena’s older wood frames.
What Rekey Locks Costs in Altadena
Here’s a practical breakdown for Altadena homeowners, based on the work we typically perform in 91001 and 91003.
| Item | Typical range in Altadena |
|---|---|
| Service call + first lock rekeyed | $85 – $125 |
| Each additional cylinder rekeyed | $20 – $35 |
| Keyed-alike consolidation (multiple locks to one key) | $120 – $220 |
How much does it cost to rekey a house in Altadena?
Most homes in Altadena have three to five locking doors. You’re looking at roughly $85 – $125 for the first lock and $20 – $35 per additional cylinder, so a full-house rekey commonly lands between $120 and $265 on a single visit. Call (866) 497-9415 for an exact quote.
Is rekeying better than replacing locks in an old Altadena home?
Usually yes. The original mortise locksets and brass hardware on a Craftsman home are worth keeping, and rekeying preserves the fit and finish that a replacement cylinder rarely matches. We’ll tell you honestly if a lock is too worn to rekey and replacement makes more sense.
Brands We Service in Altadena
We work on the lock in front of us, not just the brands we prefer. In Altadena that means a lot of vintage Schlage and Kwikset hardware, plus high-security lines like Medeco and Abloy on homes where the owner has upgraded. We carry common pins, springs, and parts for these brands, so most rekey work in Altadena happens in a single visit. See our brands for the full list and what each one needs.

A cylinder that hasn’t been opened in 40 years may need a more careful disassembly, and a warped door frame from Santa Ana winds may require strike plate realignment before the new key works smoothly. Our price is quoted on the phone before anyone is dispatched, and that’s the price on the invoice. No call-out surcharge added on arrival.
