Rekey or replace? How to decide
Rekeying keeps your lock and changes what's inside it. We take the cylinder apart, swap the small pins that match the old key, and cut new keys to the new pin set. Every old key stops working, and the door looks exactly the same.
Replacing the hardware, or changing the locks outright, makes more sense when:
- The lock is worn, loose, or the bolt no longer throws all the way.
- You want a different style or finish, say a new handle set to match a repainted front door.
- The existing deadbolt is a light-duty model and you want a sturdier one.
- The house has a mix of brands, and some won't take a common key.
Rekeying is also the answer when a key goes missing. Say your key ring disappeared somewhere between a Southwestern College class and the Otay Ranch Town Center parking lot, and your address was on something in the same bag. A rekey makes that lost key useless without touching the look of your door. Same for a housekeeper who stopped coming, a roommate who moved out, or an ex who never returned a copy.
Just bought a home? Rekey on day one
When you close on a house, you get the keys the seller hands over. You don't get a list of everyone else who has one. Many 1980s and 1990s homes in Rancho del Rey, Sunbow and Hilltop are changing hands. On a resale there, that list can include past owners, their relatives, a dog sitter from years back, the listing agent's lockbox and a string of contractors.
New construction isn't a clean slate either. In the newest parts of Otay Ranch, like Escaya and Millenia, and in Eastlake's later phases, crews, inspectors and subcontractors all came and went during the build. Builders often use construction keys, and they don't always stop working the way they're meant to . A rekey settles it. In San Miguel Ranch and Rolling Hills Ranch, we can rekey on the van's tailgate while the boxes are still going into the garage.
Our move-in checklist:
- Rekey every exterior door: front, back, patio and the door from the garage into the house.
- Rekey or replace the side-gate lock if it takes a key.
- Reset the garage door opener code and the exterior keypad, and clear old remotes from the opener.
- Check that every deadbolt throws fully and the strike screws reach the framing.
- Count the new keys, and decide who gets one.
Items 3 and 5 are yours. We handle the rest in one visit.
One key for every door
Keying alike means one key opens the front door, the back door, the garage entry and the side gate. It's the most common request we get on west-side homes in Castle Park and Montgomery, where a 1950s or 1960s house might have a front knob from one decade, a back deadbolt from another and a garage lock from a hardware-store sale.
Deadbolt installation and handle set replacement
For deadbolt installation, we fit residential deadbolts in Grade 1 and Grade 2, the two sturdier ratings in the ANSI/BHMA standard. We also install new knobs, levers and full handle sets. On a 1950s door in Castle Park or Montgomery, we check the bore first, because many older doors were drilled for a knob and never for a deadbolt.
- Longer strike screws. Three-inch screws that reach the stud behind the jamb, instead of the short ones that only bite the trim.
- A matched finish. The new deadbolt matches the knob, the hinges and the kick plate, so one replaced lock doesn't stand out on the door.
- Keyed to what you have. The new lock takes the same key as your other doors, so replacing one lock doesn't mean a new key ring.
Lock repair for sticky cylinders and stiff keys
Not every stubborn lock needs replacing. Castle Park Locksmiths repairs residential locks with these common problems:
- A key that turns hard or sticks. Often a dirty or dry cylinder, sometimes a worn key. We clean the cylinder and cut a fresh key.
- A bolt that won't throw. Usually the door has settled. We adjust the strike or the door rather than forcing the lock.
- A loose knob or lever. Stripped mounting screws or a worn spindle, fixed in place.
Near the Bayfront and the Sweetwater Marsh, in west-side 91910 and 91911, we see more corroded cylinders and seized latches from the damp salt air.

Rekey and lock change questions
Should I rekey or change my locks?
Rekey if your locks work well and you only need the old keys to stop working; change them if the hardware is worn, light-duty or not the look you want. Rekeying keeps the lock on the door and swaps the pins inside, so it usually costs less and the door looks the same. Changing also makes sense when a 1950s Castle Park or Montgomery house has a mix of brands that won't take one key.
Should I rekey my house after moving in?
Yes, on the first day. The seller hands over their keys, but past owners, relatives, agents and contractors may still hold copies, whether it's a resale in Rancho del Rey or Sunbow or a new build in Otay Ranch. We rekey every exterior door, including the door from the garage into the house and the side gate, in one visit, so only the keys in your hand work.
Does a brand-new home need a rekey?
It's worth doing. During a build in Otay Ranch's Escaya or Millenia, or in Eastlake's later phases, crews, inspectors and subcontractors come and go, and nobody gives you a list of who handled a key. A rekey on move-in settles the question without replacing the new hardware or changing its finish.
Can you make one key work on all my doors?
Usually, yes, when the locks share a keyway. Keying alike means one key runs the front door, back door, garage entry and side gate. On older west-side homes in Castle Park and Montgomery, where a front knob and a back deadbolt can be decades apart, we replace any lock that can't take the common key with one that can. Text us the brand name on each lock face and we tell you what will key together.
Why is my front door lock sticking?
Most often the cylinder is dirty or dry, or the door has settled so the bolt drags on the strike. In west-side 91910 and 91911 homes near the Bayfront and the Sweetwater Marsh, damp salt air is also hard on brass and steel. We clean and lubricate the cylinder, adjust the strike or the door, and cut a fresh key from code. When corrosion has gotten into the pins, we replace the cylinder rather than keep cleaning it.
Moving in, or down to one key?
Call to book a rekey or a new deadbolt. Tell us how many exterior doors you have and whether there's a side gate.
