Why Dunmore Locksmith Is Tustin’s Preferred Change Door Locks Company
Tustin homeowners call us because the housing stock here demands a locksmith who actually understands old hardware, not just someone who swaps cylinders on modern spec homes. A big part of our reputation in Tustin comes from work on pre-1950 doors, where a standard Kwikset cylinder will not fit an original mortise lock case without modification. Perry Osgood, who leads Dunmore Locksmith, drills every technician on this: identify the hardware before touching it, quote a written price, and never upsell a replacement when a rekey is the honest fix.
We also get repeat calls from Tustin Ranch and Tustin Legacy residents who appreciate the Threshold Standard. That means every technician is background-checked, identity-verified, uniformed, carrying a photo ID badge, and sent to you by name and photo before the visit. You never open the door wondering who is standing there. Our Change Door Locks in Tustin customers tell us that single detail matters more than speed.
Response time to most Tustin addresses runs 30 to 45 minutes during normal hours, and we maintain 24-hour coverage so a lock change at 2 a.m. gets the same written-price treatment as one at noon.
Change Lock Cylinder in Tustin
Change Lock Cylinder work in Tustin is the job that separates a parts-swapper from a real locksmith, because so many of our local doors use non-standard cylinders. What the term means: we remove the existing lock cylinder, the part your key slides into, and install a new one with new pins and keys. For a modern deadbolt on a Tustin Ranch door, that is usually a 20-minute job and costs $85 to $140. For an Old Town Tustin home with a 1910s mortise lock, the cylinder may need to be sized to the original cast-iron case, and that runs $150 to $240 because the work requires custom fitting rather than a drop-in swap.
When Rekeying Is the Smarter Call
Rekeying means changing the internal pins inside your existing cylinder so the old keys stop working. If the lock body, the cylinder housing, and the strike plate are all in decent shape, rekeying is almost always the better choice for a Tustin homeowner. It costs less than replacing the cylinder, and on antique mortise locks, it preserves hardware that cannot be matched at a big-box store anyway.
When the Cylinder Must Be Replaced
You need a new cylinder when the old one is cracked, the keyway is so worn a key wiggles loosely, or someone broke a key off inside and the extraction damages the plug. We stock Abloy, Medeco, and Baldwin cylinders in common Tustin formats, and we order spec-matched cylinders for the older mortise cases around Old Town when needed.
Door Lock Installation in Tustin
Door Lock Installation in Tustin almost always means one of two scenarios: a brand-new deadbolt or handle set on a door that never had one, or a replacement lock on a door where the existing hardware failed. Basic installation of a Kwikset or Baldwin single-cylinder deadbolt runs $120 to $190 including the hardware. A higher-security Medeco or Abloy deadbolt with a reinforced strike plate runs $200 to $285. If your Old Town door has an original mortise lockset, installation may require routing or chiseling the door to fit a modern lock body, which adds $60 to $120 for the case work.
Retrofitting Old Doors Without Ruining Them
A lot of what we do in Tustin is retrofit work on original doors that deserve to stay original. We can often install a modern deadbolt above an existing antique lockset without removing the historic hardware, preserving the look while adding modern security. The price is the same as a standard installation plus a small retrofitting charge, and we always show you the written total before drilling.
Smart Lock and Electronic Deadbolt Setup
Newer Tustin Legacy apartments and 2010s-era Tustin Ranch homes often want electronic deadbolts. We install and program Yale and Baldwin smart locks, including keypad models and ones that pair with a phone app. Installation runs $180 to $320 depending on the lock and whether you need the app set up and tested with you on site.
Trusted Brands We Service in Tustin
We are factory-authorized to work on Schlage, Medeco, Mul-T-Lock, Abloy, Baldwin, Yale, Kwikset, and Sargent hardware, which matters because Tustin homes carry all of them. Tustin Ranch tract homes from the 80s and 90s run heavily on Kwikset and Schlage. Tustin Legacy buildings skew toward Yale and Baldwin. Old Town doors are the wildcard: original mortise locksets that sometimes need parts matched by size and era, not brand. Our Change Door Locks team keeps common cylinders, tailpieces, and strike plates stocked for all three eras, so most Tustin jobs finish in one visit.
Common Change Door Locks Problems We See in Tustin Homes
- Original mortise locks in Old Town bind because the door itself has warped. A 1920s wood door that has swollen and shifted over a century will press a lock bolt against the strike plate no matter how good the lock is. We fix the alignment first, then decide if the cylinder even needs work.
- Modern deadbolts dropped into old doors fail early. We regularly see Tustin homeowners who bought a standard Kwikset deadbolt and tried to install it in an old mortise door. The case dimensions do not match, and the cylinder ends up misaligned. That requires retrofit work, not just another new lock.
- Aluminum sliding door locks in Tustin Ranch bind in the heat. Tustin inland temperatures run 10 to 15 degrees hotter on summer afternoons than coastal Orange County, and the wider day-night temperature swing makes aluminum frames expand and contract. The misalignment causes the lock to stick, and coastal locksmiths rarely see it at this frequency.
- Mixed hardware eras in a single house. Many Tustin homes have been renovated in stages, leaving a 1990s Schlage deadbolt on the front door, an original mortise lock on a side door, and a smart lock on the garage entry. That is not a problem for us, but it confuses homeowners trying to buy one brand and make everything match.

FAQs About Change Door Locks in Tustin
We can rekey most original mortise locks in Old Town Tustin homes, and doing so preserves hardware that cannot be replaced off the shelf. Rekeying an antique mortise cylinder runs $85 to $140 if the cylinder is intact. Replacement only becomes necessary if the cylinder is cracked, the keyway is wallowed out, or a previous repair damaged the plug. Call (910) 714-4287 and describe your door; we will tell you honestly which path applies.
Your Tustin Ranch sliding door lock binds because the aluminum frame expands and contracts with Tustin’s inland temperature swings, which can shift the door slab enough to jam the lock bolt against the keeper. A front deadbolt on a wood door does not experience the same thermal movement. The fix is realigning the door and often adjusting or replacing the sliding door lock, not just lubricating it. We handle this constantly in Tustin Ranch.
Rekeying changes the internal pins so the old key stops working, while changing the cylinder removes and replaces the whole keyway unit. In a Tustin Legacy apartment, most move-in lock changes are rekeys, which cost $85 to $110 per lock. You would change the cylinder only if the apartment uses a worn or damaged cylinder, or if you want a higher-security keyway. We can tell you which one your building needs from a photo or a quick visit.
Yes, we stock common antique mortise lock parts and source era-matched cylinders for Old Town Tustin storefronts along El Camino Real and nearby streets. In one 1910s storefront near the 300 block of El Camino Real, our tech opened a binding original cast-iron mortise lock non-destructively and replaced only the worn cylinder with an Abloy unit sized to the existing case, leaving the historic hardware intact. On a second door on the same block, a simple rekey with new pins was the honest fix. If you own a historic Tustin storefront, call (910) 714-4287 and we will assess what your hardware actually needs.
For most Tustin homes, a Grade 1 deadbolt with a bump-resistant cylinder is the smartest security upgrade, and it runs $200 to $285 installed for brands like Medeco or Abloy. If your home is in Old Town, we also recommend keeping the original mortise lock functional and adding a modern deadbolt above it rather than gutting the historic hardware. We will give you a written price for either setup before any work starts.
